Note: Other oils or refrigerants may be used in your chamber Equipment Start-Up/Installation CHAMBER INSTALLATION

First, locate the area in which your chamber will be installed. Check the area selected for its serviceability to the machinery compartments, both electrically and mechanically. In the event your equipment is too large to move through halls and doorways, consult factory as to what can be detached for the move in.

Place equipment in desired location, reinstall any detached components that had been detached through arrangements with Weiss Technik for the move in. We recommend that the chamber and machinery compartment (being either a self- contained system or component system) be leveled. Leveling helps assure the systems’ optimum performance promoting good oil return on the refrigeration system and proper drainage of any accumulated moisture.

ELECTRICAL INSTALLATION

Electrical power for your test chamber is typically supplied in one of two methods.

One method of connecting your test chamber to electrical power is with the use of a receptacle and plug. Before connecting power, verify current voltage and phase of your chamber. This information is located on the equipment’s’ specification page and on the electrical drawing. If you have any questions regarding your chamber power requirements, please consult the factory. The use of improper power can void your warranty.

Another method of connecting electrical power to your equipment is by hard wiring. A main power distribution block or a main power disconnect (optional) will be located in the electrical compartment for this purpose. Again verify that proper voltage and current requirements have been supplied according to the information on the equipment specification page and on the electrical drawing.

For questions regarding wire sizing, conduit sizing or conduit piping practices, please consult a licensed contractor in your area or your facilities manager. State, local and company codes govern the methods and practices used on installation of electrical hook ups and use your LOTO Procedures.

WARNING: Dangerously high voltages are present. Do not turn on the electrical power until you are instructed to do so in the start -up procedure.

WARNING: Disconnect the electrical power before working near moving parts. Keep all guards and shields in place.

ELECTRICAL SYSTEM

An electrical system drawing has been included in this manual. Please refer to the drawing during the following explanation of the system.

You will note in the upper left hand corner of the drawing, the appropriate voltage and current requirements of the system. Before applying power to the system, verify that the appropriate electrical service has been supplied.

There are numbers running vertically along the left side of the print. These are line numbers that allow you to utilize the information given along the right hand side. Along the right side of the circuitry, you will find line identifications and numbers. These numbers will indicate what line(s) a component such as a contactor (or relay) has contacts located. Multiple line numbers indicate that there are several contacts.

The print shows all of the wires located within the system. The main control wires have been returned to the main terminal strip within the electrical enclosure for ease of troubleshooting.

Please note that all high voltage components have a current rating shown on the drawing. It is generally recommended that these readings be checked during the start-up procedure. During normal calibration or preventive maintenance checks, it is recommended that current readings be taken to verify that everything is in good working condition. Readings should be within +/-10% of the ratings shown on the drawings.

If a high-heat limit is shown on the drawing, it is recommended that the performance of this limit be checked periodically. Simply adjust the temperature setting of the high heat limit (typically set at 360˚ F) to a lower value and verify that it trips. Once the device is tripped, a manual reset is required.

WARNING: Dangerously high voltages are present. Do not turn on the electrical power until you are instructed to do so in the start -up procedure.

WARNING: Disconnect the electrical power before working near moving parts. Keep all guards and shields in place.

LN2 BOOST INSTALLING A GN2, LN2, SYSTEM

WARNING: Improper installation of a GN2 (gaseous nitrogen), or LN2 (liquid nitrogen), system can cause death by suffocation. Make sure the chamber is vented to the following instructions.

1. Connect a vent line from the chamber vent, located on top of the chamber, to the outside of the building.

• Make sure the vent outlet is not near a fresh air intake to the building.

• To prevent back pressure, the vent line must be short, straight, and at least as large in diameter as the chamber vent.

• If your chamber has more than one vent, repeat this step for the other vent(s).

2. Find the GN2, LN2 inlet on the chamber (the assemblies are labeled), and connect the needed supply:

• For GN2 systems, connect a gaseous nitrogen supply to the inlet at a maximum pressure of 100 psig.

• For LN2 systems, connect a liquid nitrogen supply to the inlet at a maximum pressure of 80 psig. Include a high-pressure relief valve in the line, and insulate the line.

3. Use a leak-detecting solution to check for leaks.

The cooling portion of this Weiss Technik Test Chamber is being enhanced through direct injection of liquid nitrogen. This is used as a boost for faster pulldown rates.

The system utilizes a redundant solenoid as well as a control solenoid. The redundant solenoid is enabled whenever there is a cooling command.

The control solenoid circuit is enabled via a delay timer. This timer setting should be great enough to avoid overshooting at control. A repeat cycle timer is also energized (sometimes called a percentage timer) cycling the control solenoid off

Equipment Start-Up/Installation

LN2 BOOST INSTALLING A GN2, LN2, SYSTEM (Continued)

then back on. This repeat cycle timer can be changed to vary the pulldown rates. An indicator light next to the function switch will indicate when the LN2 control solenoid is open.

Power will be de-energized to the LN2 boost circuit when the cooling output of the controller starts pulsing as the chamber nears the setpoint.

WARNING: Avoid exposing yourself to air and equipment that is not at room temperature. Please check the equipment nomenclature to see if the LN2 boost applies to your chamber.

LN2 COOLING INSTALLING A GN2, LN2, SYSTEM

WARNING: Improper installation of a GN2 (gaseous nitrogen), or LN2 (liquid nitrogen), system can cause death by suffocation. Make sure the chamber is vented to the following instructions.

1. Connect a vent line from the chamber vent, located on top of the chamber, to the outside of the building.

• Make sure the vent outlet is not near a fresh air intake to the building.

• To prevent back pressure, the vent line must be short, straight, and at least as large in diameter as the chamber vent.

• If your chamber has more than one vent, repeat this step for the other vent(s).

2. Find the GN2, LN2 inlet on the chamber (the assemblies are labeled), and connect the needed supply:

• For GN2 systems, connect a gaseous nitrogen supply to the inlet at a maximum pressure of 100 psig.

• For LN2 systems, connect a liquid nitrogen supply to the inlet at a maximum pressure of 80 psig. Include a high-pressure relief valve in the line, and insulate the line.

3. Use a leak-detecting solution to check for leaks.

The cooling portion of this Weiss Technik Test Chamber is through direct injection of liquid nitrogen.

The system utilizes a redundant solenoid as well as a Baumann LN2 control valve. The redundant solenoid is enabled when the cool switch has been turned on and the controller is calling for cooling. The redundant solenoid will close after there hasn’t been a cooling demand for 90 seconds.

The Baumann I/P positioner receives a linear 4-20mA signal from the controller.

Equipment Start-Up/Installation

LN2 COOLING INSTALLING A GN2, LN2, SYSTEM (Continued)

The positioner converts this signal to an air pressure based on the following for- mulas 4-20mA = 3-15 psig. The air pressure then opens the control valve allowing LN2 to be injected into the chamber. When the chamber nears the setpoint, the pressure will be reduced allowing the valve to close, thereby reducing the flow of LN2. An indicator light next to the function switch will illuminate when there is a cooling signal to the I/P converter.

Your chamber is equipped with a Baumann Series 763 Single-Acting Positioner. Before operation, you may need to verify calibration. Sometimes during shipment, settings may change. Use operation instructions contained in this manual to re-cali- brate if required. If you require further assistance with this procedure, please call our Product Support Group.

REFRIGERATION SYSTEM INSTALLATION

Prior to starting any refrigeration system, the following checks should be made.

1. Verify that all refrigeration lines remained secure during shipment.

2. Look for the presence of fractured lines. This is sometimes indicated by the presence of an oil mist coating lines and components.

3. Backseat all valves with yellow tags prior to start-up. Your system has been pumped down for shipment. (If applicable to your chamber.) Reference yellow sheet on the inside of the electrical box door. Initials on this sheet will indicate the number of valves front seated.

Equipment Start-Up/Installation

REFRIGERATION SYSTEM INSTALLATION (Continued)

CAUTION: To remove compressor, heavy component: Compressor weighs greater than 65 lbs. To safely remove, you should first slide the compressor towards the rear of the (tool) chamber before attempting to lift it. This requires a two-person lift.

REFRIGERATION SYSTEM The refrigeration portion of your Weiss Technik test chamber may be configured in one of many variations, based on the size of the compressors. Refer to the enclosed system drawing during the following explanations of system operation. Weiss Technik recommends using a trained refrigeration technician. Call our Service Department for help and cost to assist 1-800-368-4768 or visit www.weiss-na.com. By referring to the electrical drawing, you are able to determine which safety devices have been installed in your system. These devices will be located directly to the left of the compressor safety relay (generally marked CR2). Typically, there are from two to six safety devices, depending on the size of the system. The high-low pressure switches are intended to monitor the pressures within the individual refrigeration systems. If the high-low pressure switch(es) are tripped, they must be reset manually. Do not reset more than twice without consulting the factory. Each compressor will have oil pressure monitoring via an oil pressure system, pressure transducer or other monitoring system. The oil level should be observed at the oil level indicator on each compressor. The oil levels should be maintained per compressor manufacturer's recommendation. If improper oil levels are observed, our Product Support Group should be contacted.

Inherent overload protection may also be included in the compressors. If tripped, these devices must cool down before they reset themselves. If the inherent protection is tripped, our Product Support Group should be contacted.

Equipment Start-Up/Installation

NOTE: THE TERM HIGH SIDE APPLIES TO SINGLE STAGE SYSTEMS AND THE HIGH SIDE OF CASCADE SYSTEMS.

Equipment Start-Up/Installation

CAUTION: ONLY QUALIFIED SERVICE PERSONNEL SHOULD ATTEMPT TO CHARGE A REFRIGERATION SYSTEM. LOW SIDE REFRIGERANT CAN EXCEED A PRESSURE GREATER THAN 600 PSIG AT AMBIENT TEMPERATURE. EXTREME CARE SHOULD BE USED IN HANDLING THIS REFRIGERANT.

LOW SIDE REFRIGERATION SYSTEM CHARGING PROCEDURE To verify that the low side pressures are normal, first look at the serial tag located within the electrical compartment. Compare the actual pressure with the pressure required.

To obtain the system standby pressure, follow this procedure:

1. Backseat the suction and discharge service valves on the low side compressor; valves turned all the way counterclockwise.

2. Connect a set of manifold gauges to the system, suction gauge to suction service valve and discharge gauge to discharge service valve. Attach the center hose to the tank of refrigerent. Prior to allowing gas to enter the system, the hoses should be evacuated by using a vacuum pump or an EPA recognized method of purging the hoses.

3. After the lines have been either evacuated or purged, close the supply tank and tighten all of the fittings. Then open both the suction and discharge valves 1/2 turn. The standby pressure of the system will now be observed on the gauges. Proper charges will be read only if the chamber and cascade condenser are stabilized at ambient temperature.

If, after observing standby pressure, it is determined that additional gas is required, follow this procedure:

1. Leak check entire system with either electronic or Halide leak detectors. 2. Repair leaks as necessary. 3. Evacuate system. 4. Attach manifold as previously discussed. 5. Open both manifold valves and open the supply tank to allow gas to flow into the system. When the gauges record the proper standby, close the valve on the supply tank. Allow the chamber to stand for 15 minutes to stabilize the pressure. If required, add additional refrigerent and repeat the above procedure until the proper standby pressure is maintained. 6. After the proper pressure has been maintained, close both manifold valves (clockwise) and the supply tank valve. 7. Allow the system to run and verwify operating pressures. 8. If pressures are normal, backseat the compressor service valves and remove the gauges.

Equipment Start-Up/Installation

CAUTION: ONLY QUALIFIED SERVICE PERSONNEL SHOULD ATTEMPT TO CHARGE A SYSTEM.

HIGH SIDE OR SINGLE STAGE REFRIGERATION SYSTEM CHARGING PROCEDURE

The high side system is not charged by standby pressures. To monitor the high side of the system, turn the system on and set in a low temperature set point so that the system is reducing the chambers temperature (pulldown). After 2 minutes of operation, observe the sightglass. The sightglass P should be free of all bubbles. If not, additional refrigerent is required.

To charge the system, proceed as follows:

1. Backseat the suction and discharge service valves on the high side compressor. Valves turned all the way counterclockwise.

2. Connect a set of manifold gauges to the system, suction gauge to suction service valve and discharge gauge to discharge service valve. Attach the center hose to the tank of refrigerent. Prior to allowing gas to enter the system, the hoses should be evacuated by using a vacuum pump or an EPA recognized method of purging the hoses.

3. After lines have been either evacuated or purged, close the supply tank and tighten all fittings. Then open both the suction and discharge valves 1/2 turn. The pressure of the system will now be observed on the gauges.

4. Allow the system to operate for 2 minutes (minimum).

5. Open the suction manifold only. DO NOT PUT REFRIGERANT INTO THE DISCHARGE PORT. Allow liquid refrigerant to flow into the suction side until the sightglass becomes clear. Do not allow suction pressure to exceed 50 PSI while adding liquid refrigerant.

6. Continue to monitor the sightglass during the pulldown and if required, add more refrigerent.

7. After the bubbles clear, backseat the compressor valves, frontseat the manifold valves and remove the gauges.

The jack shaft(s) and blower wheel(s) combination may have been removed from this environmental test chamber due to shipping height considerations. Please follow this procedure to insure proper performance and reliability.

1. Mount this jack shaft assembly on the top of the chamber in the orientation shown on your assembly drawing. The bolts needed have been placed back in their proper holes on top of the chamber. Remove these before setting the jack shaft assembly in place, on top of the 1/8” thick neoprene gasket. Bolt down the jack shaft assembly with the bolts, lock washers and flat washers provided.

2. Now that this is done, determine the shaft that each blower wheel will mount on. (This will be marked on each wheel.) Remove the inlet cone(s) from the plenum. Inspect the interior shafts and blower wheel. The shaft also has a washer and a LH threaded screw tapped into its end; remove these for blower installation.

Note on the blower wheel, the two set screw locations. There are two set screws per hole; the second one is to lock the first set screw in position. Each set screw must be prepared with the removable “loctite”.

3. Prepare each set screw with “loctite” and thread into the tapped hole without protruding into the bore. Insert the keyway into the keyseat and slide the blower wheel onto the appropriate shaft. The back plate of the blower wheel should be approximately 1” from the chamber liner.

4. Align the set screw to the drill cup located on keyways and tighten to the shaft. Then thread the “jam” set screws into each tapped hole and tighten. Replace the washer and LH bolt in the end of the shaft and tighten. Repeat this paragraph for each blower wheel. Equipment Start-Up/Installation

JACK SHAFT / BLOWER WHEEL INSTALLATION (Continued)

5. Re-install the inlet cone for each wheel, make sure the wheel will not rub on the inlet cone when spinning. Make any appropriate adjustments.

6. Make sure all bolts and set screws are tight. Then re-connect the liquidtite conduit to the motor(s); wire as shown on the motor nameplate. The final step is to attach the jack shaft guard to the jack shaft framework.

LUBRICATION PROCEDURE

Lubricating the fan shaft bearings is a very important preventive maintenance procedure that must be upheld in order to extend bearing life.

It is recommended that the bearings be lubricated once every month for a chamber that is operating 40 hours per week or greater and once every two months for a chamber that is operating 20-40 hours per week. The recommended lubricant is Dow Corning BR2-Plus or a grease conforming to NLGI grade #2.

When lubricating the fan shaft bearing, it is best to look at the bearings to prevent over-greasing. Add grease to each bearing until the first sign of grease is exiting out from between the bearing and the outer race. This is a sign that the bearing is properly lubricated. The recommended amount of grease is 1 to 2 strokes (5/8 to 7/8 oz.) with a standard grease gun.

Follow the above directions very carefully to maintain optimum performance characteristics. Please call our Product Support Group if there are any questions regarding this procedure.

HUMIDITY SYSTEM

Weiss Technik offers two different types of humidity systems. The first is a Mechanical Humidity System or steam generator type. The second being an Atomizing Humidity System.

It is very important to determine which type of humidity is incorporated in your environment test chamber.

CAUTION: Humidity chambers need purified water to create humidity. As the water is heated to create vapor for humidity, it leaves any impurities behind. Supplying straight tap water will leave deposits on the humidity heater, which requires more cleaning, produces less efficient heating, and shortens the heater’s life.

On the other end of the spectrum is water that is too pure. Water which is too pure will try to refresh itself with missing minerals. Over time, too-pure water will etch holes into the stainless steel material on the chamber. A hole in a chamber will allow moisture to fill up the insulation space.

Weiss Technik recommends having your supply water (tap water) evaluated by a reputable source to identify impurities in your water supply. One such source would be Thermo Scientific (Barnstead). This is usually a free service.

TERMINOLOGY: What is deionization? Deionization (or demineralization) simply means the removal of ions. Ions are electrically- charged atoms or molecules found in water which have either a net negative or positive charge. For many applications using water as a rinse or ingredient, these ions are considered impurities and must be removed from the water.

ACIDITY: pH Value – measured on a scale of 0 to 14 -0 = very acid -7 = neutral -14 = very alkaline

TURBIDITY: Suspension of fine, non-dissolving particles in water; sometimes indicated by cloudy or colored water and usually measured in ppm (parts per million).

Equipment Start-Up/Installation

CAUTION Continued:

HARDNESS/ION CONTENT: Many compounds, mainly calcium and magnesium but including sodium, potassium, chloride, nitrates, iron, copper, etc., break down and dissolve in water. Measured by resistivity (Ω-cm); conductivity (µmho/cm), or complete water analysis (ppm each contaminant).

HUMIDITY WATER REQUIREMENTS: TURBIDITY less than 5 NTU* and preferably less than 1 NTU* COLOR Less than 5 on the pH color scale FREE CHLORINE Less than .2 ppm CHLORAMINE Less than .2 ppm CHLORIDE Less than .2 ppm TOTAL IRON AND MANGANESE Less than .3 ppm ORGANICS Less than 1 ppm (as determined by oxygen ACIDITY (pH) Between 6 to 7 pH RESISTIVITY Between 50,000 Ω to 1 MΩ.

* Turbidity is measured in NTU: Nephelometric Turbidity Units

Humidity water quality is an important issue. Non-corrosive, non-scale-forming water is required for humidity systems. Water that is super pure or impure will cause problems in the system.

EFFECTS OF UNACCEPTABLE WATER: • HEATER FAILURE • EXCESS SCALE AND MINERAL DEPOSITS IN VAPOR GENERATOR • POOR HUMIDITY CONTROL • CORROSION OF HUMIDITY SYSTEM • MINERAL “LEACHING” FROM CHAMBER OR PRODUCT

WEISS TECHNIK RECOMMENDED WATER DEIONIZATION SYSTEM: Supply water regulated to 25-30 psi. Pre-filter to remove the rust/iron from the supply water, using the followingBarnstead - brand products: D5839 B-Pure, ½ size filter holder (one each) D2780 Dual pressure gauge kit (one each) FL583X1 5 Micron Filter, ½ B-Pure

Equipment Start-Up/Installation

CAUTION Continued:

After the pre-filter, use a D0832 cartridge (contains carbon and mixed-bed resin) to remove the chlorine, chloramine and chloride from the water. After the pre-filter, this is the first filtration cartridge in the holder.

The second cartridge, D0809 (removes carbonates), completes the filtration process to condition the water for the chamber. Cartridge D0832 combined with the D0809 will process a total of 2350 liters to the above-listed water requirements.

The above-listed water-deionization system satisfies Weiss Technik humidity water requirements. Other systems may be used if equivalent. Using improperly-deionized water may affect your warranty if components are damaged.

RECOMMENDATION: It is also recommended the chamber be cleaned between tests using a 50/50 solution mix of distilled water and white vinegar to neutralize and clean contaminants. This will neutralize and clean contaminates between tests without adding additional chemicals.

Adding a compressed air purge system to add additional oxygen to the system is recommended in areas where chloramine is added to the supply water.

MECHANICAL HUMIDITY WATER REQUIREMENTS

On a humidity system, water is required for the steam generator. Also, systems not utilizing a solid state humidity sensor may use a wick tank to measure wet bulb temperature for relative humidity measurements. If a wick tank is included, periodic replacement of the wet sock is required. It is recommended that the wet sock is replaced once a week or prior to a test that has a duration of more than two weeks. Refer to: Humidity System Caution Section. Connect humidity inlet water to the connection provided marked humidity water inlet. Water levels in the wick tank and the steam generator are controlled automatically by individual float mechanisms.

The humidity water outlet should be connected to an open drain.

Humidity Water Reservoir Tank

If your system utilizes a reservoir tank, the tank must be placed on top or at an elevation higher than the chamber.

ATOMIZING HUMIDITY WATER REQUIREMENTS

On a humidity system, water and air is required for the atomizing humidity system. Also, systems not utilizing a solid state humidity sensor may use a wick tank to measure wet bulb temperature for relative humidity measurements. If a wick tank is included, periodic replacement of the wet sock is required. It is recommended that the wet sock is replaced once a week or prior to a test that has a duration of more than two weeks. Refer to: Humidity System Caution Section. Connect humidity inlet water to the connection provided marked humidity water inlet.

ATOMIZING HUMIDITY SYSTEM

In some systems an atomizing system is used for humidity control in lieu of a traditional steam generator system. The atomizing system consists of:

Water and air regulator/filter/gauge assembly

Control solenoids

Atomizing nozzles

Mounting plate complete with all necessary plumbing

The system is controlled by the humidity output from the programmer/controller on your system. Time proportioned outputs are used to pulse/modulate the control solenoids which then introduce the atomized mist into the plenum. Water droplets are roughly the size of a dust particle, which produces the desired fogging within the chamber.

The advantages of the atomizing system over the steam generator are: 1. Less maintenance 2. Faster response 3. Better control due to the faster response 4. Easier to install 5. Less costly to operate (110 V only is required)

Refer to: Humidity System Caution Section.

Equipment Start-Up/Installation

HUMIDITY SYSTEM OPERATION

Systems that incorporate humidity as an option, require the enabling of an Event or Auxiliary for humidity control. One type of controller is listed below for examples on how this is accomplished.

1) Solutions Plus To operate your system in the humidity mode, Auxiliary 1 must be on. This is accomplished in one of two methods. Either as part of your program, Editor Program Screens, Item #14 (Auxiliary 1) or Manual Control Screen, Item #11.

Measurement of humidity can be accomplished in two (2) different methods. A Direct relative humidity (solid state) sensor like Vaislsa’s HMM30C or wet bulb dry bulb control.

OPERATION SAFETY INSTRUCTIONS Follow all WARNINGS to prevent personal injury and death.

WARNING: To safely operate the chamber, you must read the General Safety Instructions and all the instructions in this manual.

WARNING: Avoid exposing yourself to air and equipment that is not near room temperature. Port gloves are not designed to insulate your hands.

WARNING: Using gloves left in a chamber when the temperature is lower than 0 °C (32 (F) or higher than 37.8 °C (100 °F) could cause frostbite or burn your hands.

WARNING: Use your chamber only for testing the products it was designed to test. Do not put combustible or explosive materials in the chamber.

WARNING: Keep the chamber door closed while the chamber is operating.

WARNING: Breathing gas from the GN2 (gaseous nitrogen), LN2 (liquid nitrogen) system can cause death from suffocation. Dilute the air before entering the chamber.

Follow all CAUTIONS to prevent equipment damage.

CAUTION: Do not operate the chamber beyond the specifications.

CAUTION: To protect from temperatures that are too high or too low, you must use a protection device. Product protection is your responsibility.

Before proceeding with this section, be sure that the Start-up Checklist and the Start-up Procedure have been completed. The Start-up Checklist and Start-up Procedure are completed initially when the chamber is installed and need not be repeated.

1. Turn the master switch to the “on” position. This will enable the remaining switches to be functional by providing control circuit power.

The light switch, when applicable, enables the chamber compartment light. System Operation

SYSTEM OPERATION (Continued)

2. Turn the circulator switch to the “on” position. This not only enables the circulator motor, but also provides control circuitry power to the heat and cooling switches. If the circulator does not run, refer to the Troubleshooting Guide.

3. Turn the heat switch and cool switch to the “on” positions. This will enable the controller to output accordingly with the set point entered. For operating the chamber hot or cold, both switches should be in the on position to achieve the desired setpoint. If the circulator is turned on and the heat and cool switches are off, the chamber temperature will rise above the ambient due to the fan rotation working on the air. The friction of the fan blade on the air will create the heat that is displayed on your controller.

4. If applicable, turn the humidity switch on when operating the chamber in a temperature/humidity mode. A temperature/humidity mode is when both the dry bulb (sensible temperature) and humidity level at that temperature are being controlled simultaneously. The humidity mode switch is typically a manual-off-auto. The position selected is determined by the test you are running. If humidity control is not desired, place the switch in the off position. If you are operating the chamber continuously in a temperature/humidity mode either through the controller key pad or via automatic programmed control, place the witch in the manual position. If you are operating the chamber via pro- grammed control only and your test requires you to change from a temperature only mode to a temperature/humidity mode, then place the switch in the auto position and activate Event #1 (or Aux#1 depending on the type of control instrument) of your program to automatically switch the system from temperature to temperature/humidity modes.

Example: Event #1 on (temperature/humidity mode) Event #1 off (temperature mode)

Every chamber is designed with specific limitations for operating the humidity system. Please refer to the chamber specifications serial tag for maximum dry bulb temperature and minimum dewpoint temperature. Weiss Technik North America, Inc.

Note: On the following Preventive Maintenance Pages, you will find a brief description of the above routine checks. Preventive Maintenance

PREVENTIVE MAINTENANCE PROCEDURES

Procedure No. 1: HIGH STAGE CHARGE

Observe the sightglass to see if there are any bubbles. This should be checked during pull down after at least 2 minutes of operation. Bubbles indicate a lack of refrigerant. If bubbles are seen during bypass operation, this does not indicate a gas shortage. Also, observe the color of the moisture indicator in the sightglass. Green is dry Yellow-green (chart reuse) is caution Yellow indicates moisture.

Procedure No. 2: LOW STAGE STAND-BY

The stand-by may be read on the low stage discharge gauge prior to the day’s operation if the equipment has been turned off overnight.

If the equipment has been running, the chamber (and cascade section) must be at ambient temperature and equalized to read the stand-by pressure.

Procedure No. 3: COMPRESSOR OIL LEVEL

With compressor(s) running, the oil levels should be maintained according to the manufacturer's recommendations. Oil leakage should not be tolerated. Any deviation from the normal oil level should be investigated immediately.

Procedure No. 4: CIRCULATOR MOTORS

Check the rotation of the fan/blower (suction at the grill) and check the fan/ blower for stress fractures and cracks on blades or vanes and tightness on the motor, shaft/jack shaft assembly. If your equipment has a jack shaft assembly, the bearings require lubrication once a month using Dow Corning BR2-Plus or a grease conforming to NLGI grade #2.

Revision Date 03/13/2015 Ref. 130000000494

Specific hazards : Cylinders are equipped with pressure and temperature relief devices, but may still rupture under fire conditions. Decomposition may occur. Contact of welding or soldering torch flame with high concentrations of refrigerant can result in visible changes in the size and colour of the torch flame. This flame effect will only occur in concentrations of product well above the recommended exposure limit. Therefore stop all work and ventilate to disperse refrigerant vapors from the work area before using any open flames. This substance is not flammable in air at temperatures up to 100 deg. C (212 deg. F) at atmospheric pressure. However, mixtures of this substance with high concentrations of air at elevated pressure and/or temperature can become combustible in the presence of an ignition source. This substance can also become combustible in an oxygen enriched environment (oxygen concentrations greater than that in air). Whether a mixture containing this substance and air, or this substance in an oxygen enriched atmosphere become combustible depends on the inter-relationship of 1) the temperature 2) the pressure, and 3) the proportion of oxygen in the mixture. In general, this substance should not be allowed to exist with air above atmospheric pressure or at high temperatures; or in an oxygen enriched environment. For example this substance should NOT be mixed with air under pressure for leak testing or other purposes. Experimental data have also been reported which indicate combustibility of this substance in the presence of certain concentrations of chlorine.

Special protective equipment : In the event of fire, wear self-contained breathing apparatus. Use personal for firefighters protective equipment. Wear neoprene gloves during cleaning up work after a fire.

Further information : Use water spray or fog to protect the fire fighters and to cool container. Self- contained breathing apparatus (SCBA) is required if containers rupture and contents are released under fire conditions. Water runoff should be contained and neutralized prior to release. Cool containers/tanks with water spray.

SECTION 6. ACCIDENTAL RELEASE MEASURES NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections before proceeding with clean-up. Use appropriate PERSONAL PROTECTIVE EQUIPMENT during clean-up.

Safeguards (Personnel) : Ventilate area, especially low or enclosed places where heavy vapours might collect. 4 / 14
