Immediately after the reception of the devices, check the condition of the packaging and whether the delivery is complete on the basis of the attached specifications and packing lists.

Unloading of the units, handling them onto the assembly site and handling of the unit parts to the site of sitting must be performed using specialized equipment and by properly qualified personnel.

The units in the facility must be stored in a hardened, dry area under a roof. A hardened area should be considered flat, horizontal, hard surface the properties of which shall remain unchanged under the weather conditions.

Units and unit elements should be stored away from areas where machine traffic (vehicles, lifts and other construction machinery) is present, in a place where they are not exposed to mechanical damages, moisture, aggressive chemical agents, dusts, sands and other external factors that may affect the condition of the units and elements stored.

Before lifting of the device make sure that inspection doors and flaps are closed.

Units should be transported only in a position in which they are normally operated and blocks must not be stacked when stored. Units and their parts should be stored in rooms where: »» relative ϕ< 80% at t=20OC »» ambient temperature -40OC < t < +60OC »» the devices are prevented from exposure to dusts, caustic gases and vapours, and other chemical agents causing corrosion to the equipment and structural elements of the device.

For the storage period unseal the film.

Any damages resulting from improper handling of the units or their elements in the facility, unloading and storage are not covered by the warranty, and any claims in this respect shall not be considered by JUWENT.

5. SITTING, MOUNTING AND CONNECTIONS

5.1. SITTING The unit should be set on: »» foundation screed; »» steel foundation framework embedded in the floor; »» specially prepared rigid steel structure. Foundation, framework or steel structure must be flat and level to ensure that stability is kept throughout the entire period of use and be of sufficient strength adequate to the weight of the unit.

10 www.juwent.com.pl 5.2. SITTING LOCATION The unit should be set so as connections of the related systems (ventilation ducts, pipeworks, cable routing) create no collision with inspection panels. In order to ensure efficient mounting, use and service of the units, keep a minimum distance equalling to at least the unit width +200mm between the operation side and the structural elements (walls, supports, pipeworks, etc.) present in the installation site however no less than 100cm. Within the operational space it is permitted to install systems, pipeworks, support structures only if their disassembly and assembly can be done problem-free for the time when service and repair works are performed. 5.3. CONNECTING VENTILATION DUCTS Ventilation ducts should be connected to the unit using flexible connections preventing transmission of vibrations and eliminating slight alignment deviations between a duct and the unit outlet. Ducts connected to the unit must be supported or suspended on own support elements. Method of routing the ducts with fittings should eliminate the possibility of increase in noise levels within the ventilation system. 5.4. CONNECTING HEATERS AND COOLERS Connecting heat exchangers should be carried out so as to protect them against likeliness of stresses which could cause mechanical damages or leaks. Connections on heat exchanger should not be affected by weight of the pipework or thermal stresses. Depending on local conditions use compensation in pipework system on supply and return lines in order to reduce length-wise expansion of the pipes. During installation of the supply system to heat exchangers with threaded connection, heat exchanger connection should be locked using an additional wrench. The supply system should be arranged so that it does not impede access to other sections of the unit. Supply and return line connections on heat exchangers should be connected so as the heat exchanger operates counter-flow. Counter-flow operation reduces average difference in temperature which determines the heat exchanger efficiency. Connection of freon cooling coil to the supply system with refrigerating unit should be carried out by a qualified cooling system technician in accordance with valid rules for freon cooling equipment. Once installed heat exchangers should be heat insulated with e.g. mineral wool with aluminium foil. 5.5. CONDENSATE DRAINAGE In drip trays in the cooler and cross-flow heat exchanger, condensate drainage tubes are installed, and they are lead outside the unit housing. A trap, formed of a flexible hose, is normally installed on tank connection of cross-flow heat exchanger. The trap should be connected to the drip tray tube, and is intended to drain water dropping out of the heat exchanger at various pressure values in the section and in the ambient. The assumed height H should be 100mm. Drain trap of the cooler drain tray should be ordered separately.

Fig. 2. Siphon on suction side

www.juwent.com.pl 11 5.6. ELECTRICAL CONNECTION Electrical connections of elements of the unit equipment should be carried out by properly qualified and authorized people in accordance with standards and regulations valid in a country of the device installation. Sections and types of cables (e.g. screened cables) feeding the individual functional equipment items should be selected according to current rating and conditions specific for the unit location (e.g. ambient temperature, method of cable installation, distances from the power cubicle). Before connecting the power supply make sure the voltage and frequency values of the mains are compatible with the data given on data plates of the devices. Admissible tolerances in values of the supply voltage and its frequency in relation to the values given on the data plate are ±5%. If any incompatibilities are found, do not connect the devices. 5.7. ELECTRIC HEATER Connection of the heater should be carried out so as it is protected against possibility of activating the heater if the fan is not on. Apart from that if the fan operation is interrupted, the heater’s power supply must be disconnected. The heater’s power is stepless adjustable. The heater’s heating coils will be damaged if supply voltage is fed with no air flow. The must be incorporated into the heater’s control system. Operation of the thermostat is based on the properties of a bimetallic element causing opening of contacts in the heater’s supply control circuit with the air temperature around the thermostat of 65°C. After an automatic emergency stop of the heater the air temperature is reduced by 20°C. After a scheduled or an emergency (caused by overheating) supply voltage cut-off, the supply air fan must operate for an adequate time (0.5-5 mins) to cool down the electric heater’s heating coils. 5.8. FAN MOTOR In RGS recuperators 1-phase 1~230V electrically commutated (EC) fans are used. The EC fans feature very high efficiency, low noise level and high durability and reliability. Control signal dependant rotation adjustment enables accurate and optimum adjustment of the unit’s operation within a particular ventilation system. All electronic control elements are integrated within the motor housing: »» motor thermal protection system PTC (requires no additional external thermal protection); »» rotation adjustment system, which can be controlled by an external controller with 0…10V DC analogue signal. An analogue signal also can be achieved using potentiometer (10kΩ ) connected to adequate terminals. RGS recuperators, depending on their size, are equipped with two or four fans. As standard the recuperator’s fans are equipped with two 0.4m cables suitable for power supply and control connection. Connection of the fan’s cables to supply and control cables should be carried out in an additional junction box (to be ordered separately). Marking of the cable wires in accordance with diagrams, Figure 3 or diagrams provided by JUWENT (for orders including automatic equipment). Maximum section of a supply cable for all unit types: 2.5mm2, while control cable: 1.5mm2. In order to avoid any interferences, pay attention to sufficient clearance between supply and control cables. Length of control cables should be max. 30m, and if longer than 20m cables must be screened. When a screened cable is used, the screen should be one-side connected to protective conductors, i.e. only to a device with protective conductor.

Do not route supply cables through inspection panels. Do not start motors if they are not provided with short circuit and overload and voltage drop protection according to PN-89/E-05012.

Never start and operate a motor without natural or protective grounding.

ANTI-FREEZE THERMOSTAT MV1 The system protecting the heating coils against freezing (i.e. anti-freeze thermostat) is a recommended part of the control system in the ventilation and air handling units with water heating coils. The thermostat has a capillary evenly unrolled along the field of the heating coil that - after decrease of air temperature (even on a short section of the capillary) below the limit temperature (recommended 5OC) - transmit a signal to the controller, which - to the thermostat’s response - signals an alarm condition, turns off the fan, shuts off the external air air damper, opens completely the heating water valve of the heating coil and activates the water pump. The system returns to the normal operation condition after increase of the heating coil temperature.

After all the above inspection procedures have been completed, carefully close all inspection panels on the device.

Do not operate the device if any inspection panel is opened.

20 www.juwent.com.pl 7. USE AND MAINTENANCE Personnel in charge of the unit operation should learn the instruction manual herein before any use and maintenance. If no own personnel of the required technical qualifications is available, JUWENT Authorized Service should be called to carry out on-going inspections of the units.

Any and all damages to the unit and its parts resulting from failure to follow the guidelines in the documentation shall not be subject to repairs under the warranty.

Basic technical data of the units such as type, types and dimensions of elements (filters, heat exchangers, fans, electric motors) are included in the data sheet.

Any service works on the unit should be carried out only with the device shut off. In order to ensure safe operation of the device install a service switch outside the fan section to cut off the power supply to the fan motor during service works. Disconnection of the power supply circuit must take place with the de-energized device. Service switch should be placed nearby the inspection panel of the fan section.

Careful, regular maintenance and control of technical condition of the unit and its equipment is necessary to find any incompatibilities on an early stage before major damages occur. The herein documentation includes only general instructions for control intervals to ensure correct operation of the unit due to various external conditions of their operation and use. Therefore control intervals must be adjusted to the current conditions (contamination, number of starts, load, etc.). Personnel in charge of the unit operation should, from the moment of its starting, run on-going records in “Inspection and Maintenance Chart”, at the end of the documentation, where any works resulting from normal, routine operation of the device should be included. A carefully run record is the only valid document to confirm condition of the device operation, terms of current inspections, and any potential device malfunctions found. When it is necessary to contact JUWENT representations always give the device’s serial numbers which can be found both on the housing and in the documents delivered with the unit. Time intervals between particular activities are defined for the unit non-stop operation and for the system with low dusting and absence of other conditions which would interfere with normal operation of the device. In environments where high dusting is present in the supply and/or exhaust it is advisable to carry out inspection more frequently. Spare parts and accessories for the unit can be ordered at the local JUWENT Authorised Service Point. When placing an order, give the device type and its serial number. This information can be found on the device’s data plate. 7.1. FILTERS

With standard conditions of the unit operation, filters should be replaced approximately once every half year. An indication when filters need to be replaced (apart from visual assessment of their function) is an increase in the pressure above 150Pa. The units are equipped with G4 cartridge filters. If the final difference in pressure for a filter exceeds the value as defined, the filter must be replaced. Filters are intended to be used once. When replacing a filter also remember to clean the filtration section by dusting or wiping it with a damp cloth. If a new set of filters needs to be ordered at a JUWENT Authorised Service Point, give the filter class and size of the unit, and possibly size and number of filters. The units must be operated with installed air filters, as otherwise power consumption by the fans may exceed the set points, and thus result in burning of the motor windings. Data regarding sizes of filters is given in the list of elements on page 26.

www.juwent.com.pl 21 7.2. WATER HEATER

Water heaters in use should be equipped with anti-freeze protection system. Alternatively, in the winter period, the heater can be supplied with a non-freezing agent (e.g. glycol solution). If the supply of a non-freezing agent is cut or during the unit idle period and in situation when decrease in air temperature below +5°C is likely, the heater should be emptied. For this purpose: »» close valves for heating medium supply and discharge (cut off the heater from the heating system), »» remove drain vent and vent plug from stub connections, »» blow the heater with compressed air fed into the vent, »» in short intervals, repeat the blowing several times until only air without visible water drops comes out of the drain vent, »» put the drain vent and vent plug in place. At least every four months check whether heater panels are not contaminated. Dust deposits on the heater surface cause reduction in its heating capacity and increase in pressure drop at the air supply side. Even if the unit is equipped with filters, it is natural that on the air supply side dust will deposit on the heater panels. If excessive soiling is found, clean using the following methods: »» using vacuum-cleaner with soft nozzle from the air supply side, »» blowing compressed air jet in the direction opposite to the normal air flow, directing the air jet in line with panel arrangement, »» washing with water with cleaning agents causing no corrosion to aluminium and copper. Before cleaning provide protection of the adjacent unit sections against released dirt and dust. In order to achieve full thermal efficiency, the heater must be well deaerated. For this purpose use vent plugs on the heater’s stub connections. During the device’s idle period the heating medium flow should be limited to a minimum so that the temperature inside the device is no more than +60°C. Increase in the temperature above this value may damage some elements or assemblies (motor, bearings, parts, etc.) installed in sections adjacent to the heater. 7.3. ELECTRIC HEATER Electric heater battery consists of unprotected heating coils. During the unit operation, when the heater is out of operation, dust may deposit on the heating coils. When the heater is restarted, thick dust deposit may cause a burnt dust smell, and even present a fire hazard. In regular intervals (every 6 months), and particularly before the heating season is started, check electric connections, technical condition of heating elements whether they are not deformed, and excessively contaminated. Any potential contaminations should be removed with a vacuum-cleaner equipped with a soft nozzle or with compressed air.

Never wet clean electric heaters.

Also check functionality of excess temperature protection in the case if air flow drop occurs.

22 www.juwent.com.pl 7.4. FREON COOLING COIL Operation of freon cooling coil requires the same activities as for water heater. When washing freon cooling coil with warm water remember to empty cooling system by sucking freon into a tank. Otherwise high risk of uncontrolled increase in freon pressure and damage of cooling system may be present. 7.5. CROSS-FLOW HEAT EXCHANGER Operation of the exchanger only takes an inspection of its technical condition and soiling of aluminium panels, carried out every four months. Dirt deposits in cross-flow heat exchangers are often limited to the first 50mm in the exchanger. Before cleaning protect the adjacent sections. Necessary cleaning should be carried out using one of the following methods: »» dusting with use of a soft nozzle, »» blowing ducts with air jet in the direction opposite to the normal air flow, »» washing the entire length of air ducts with water with cleaning agents causing no corrosion to aluminium, »» more contaminated exchangers can be cleaned by rinsing them with jet of high-pressurized water. During cleaning when mechanical means are used for soiling removal: be particularly cautious and pay attention so that exchanger plates are not deformed or damaged. When using the heat exchanger at temperatures below zero, before restarting the unit dry the exchanger completely. Apart from that check: »» damper operation, »» condition of drip tray, »» serviceability of condensate drain system, »» before starting the unit fill the trap with water, »» anti-frost system for proper mounting (if mounted), »» whether by-pass damper is closed tightly, when de-frosting is not required. 7.6. FAN UNIT Before any works (fault, maintenance, servicing) on the unit, and particularly before opening inspection panels of the fan section and removing guards from live parts, make sure that: »» the device is properly disconnected from the power supply. This applies to both main and auxiliary circuits, »» rotor is in standstill, »» fan is cooled down, and the temperature on its surface presents no risk of suffering a burn, »» fan is secured against an accidental start. 7.6.1. FANS Fans are intended to transfer dust-free or slightly dusted air. They are not intended for use with aggressive gases, vapours or highly-dusted air. Fan operation in non-compatible environment may lead to damaging bearings, corrosion, unbalance of rotor and vibrations. For fan servicing check whether: »» rotor rotates freely, »» rotor is balanced and shows no run-out, »» rotor is securely mounted on the axle, »» rotor is not shifted against entry funnel, »» flexible connection (if present) is not damaged, »» all bolts mounting the fan unit elements are tightened. Loss of rotor balance may be caused by: »» dust deposits on rotor blades, »» loss of additional balance weights, »» damage to rotor blades.

www.juwent.com.pl 23 Inspect contaminations in the housing interior, rotor and motor once every 6 months, and if needed clean: »» the housing interior with vacuum-cleaner, »» rotor with vacuum-cleaner or using wet cleaning with a mild detergent. 7.6.2. MOTORS Careful, regular maintenance and control of motor condition is necessary to find any incompatibilities before major damages occur. Before any works related to the motor or other motor equipment, and particularly before removing guards provided for protection against contact with movable or live parts, make sure that the motor is correctly disconnected from the power supply. Moreover, also disconnect additional and auxiliary circuits. Follow the below safety rules: »» disconnect the power supply, »» use protection against accidental activation, »» check functionality of safe isolation of power supply, »» use guards on adjacent live parts. All the above precautions should be kept until all maintenance works are not completed and the motor is not fully assembled and ready to be started. For fan motor servicing, check whether: »» defined specifications are met (power consumption, temperature of windings, bearings), »» there are no grease leaks, »» the motor operates properly and noises coming from the motor and bearings do not get louder, »» all mechanical and electrical connections are properly fixed, »» resistance of insulation of the windings is correct, »» wires and insulations are in good condition and there are no discolorations. All changes and incompatibilities should be removed immediately. Moreover: »» the motor is properly mounted and mounting bolts are tightened, »» the motor housing is not contaminated. Excess contamination hampers the motor cooling, what in consequence may lead to overheating of the motor windings and its damage. The motor can be dry cleaned with a brush or blown with dry compressed air. 7.7. CONTROL MEASUREMENTS After having completed maintenance inspections and works, check and adjust functional parameters of the device in accordance with recommendations in item 6. Any conducted maintenance and control measurements must be recorded in Inspection and Maintenance Chart. Parameters for noise emission are given individually for each device. 8. DISPOSAL The device should be disposed of by a company specialized in dismantling and disposal of such devices.

24 www.juwent.com.pl 9. OHS INSTRUCTIONS Connection and start-up of the units should be carried out by qualified personnel in conditions compliant with valid regulations, particularly in use of electrical equipment.

Do not power the system before connecting the unit to protective system. Do not carry out any repairs and maintenance without having previously turned off the unit power supply.

Do not operate the unit with removed inspection panel from any unit section.

Person in charge of operation, repair or maintenance must be properly qualified and authorised in accordance with regulations valid in a country of the device installation.

Location of the unit installation must be equipped with the required protective equipment providing safe operation and necessary fire protection equipment in accordance with local provisions.

Despite the fact that the device has been designed and manufactured in accordance with the standards valid as for the moment of the manufacture launching, injury and damage to health when using the device is likely. This likeliness is related to frequency of accessing the device when using, cleaning and repairing it, presence of people within the danger area, and failure to respect the safety rules as set out in the instruction. Severity of the bodily injury and deterioration of health is dependent on numerous conditions which can be foreseen partially only by considering them when designing the device and by providing descriptions and warnings as pictograms in the instruction manual and on the device. Therefore residual risk is present if recommendations and advices in the instruction manual and warnings as pictograms placed on the machine are not followed. 10. INFORMATION Regular inspections carried out by qualified technical service or by JUWENT Authorised Service Points shall ensure a reliable, problem-free and long lasting operation. At any time our service technicians can be called up to conduct start-ups of the devices and carry out maintenance works on them, and are at your disposal in emergency situations.
