Tact-Air Model 10-8 Mercury Vapor Ionizer

INSTALLATION INSTRUCTIONS TACT-AIR MODEL 10-8 MERCURY VAPOR IONIZER

Components

(1) Electronics Unit -Cabinet containing electronics, fan and a metal mesh lint trap filter. (2) Stainless Wall Plate Collector Unit-White acrylic wall-mount unit containing a stainless steel plate with protective styrene grill. (3) Interconnect Cable -A twenty-five foot length of 15,000 volt insulated (GTO-15) white cable with connector fittings at each end is supplied. Longer lengths are available on request.

Component Placement Considerations

The objective of the installation is to deliver the maximum flow of negative ions through the common breathing space between the patient, the dentist and the assistant in order to carry away toxic mercury vapor generated by the drill, polishing tool and other dental procedures.

The ideal placement of the Electronics Unit is on a counter, wall cabinet or shelf near the patient’s head with ion flow directed from the head of the chair towards the foot of the chair. This will carry negatively charged mercury vapor molecules away from the patient and down the corridor between the dentist and the assistant minimizing exposure to anyone in the operatory.

The ideal positioning of the Stainless Wall Plate Collector Unit will be near the foot of the chair allowing the positively charged plate to collect the maximum volume of mercury vapor molecules with minimal re-circulation of mercury vapor throughout the Operatory. The Stainless Wall Plate Collector Unit will function anywhere in the room but try not to create an ion flow which will place the dentist or assistant directly in a line running from the Electronics Unit to the Wall Plate Collector Unit. The choice location of the Stainless Wall Plate Collector Unit should be at least five feet high to keep inquisitive children from exploring with their fingers.

The Interconnect Cable is intended to be concealed within the walls and ceiling to make it as unobtrusive as possible. Most offices have hollow walls and suspended ceilings, making it convenient to thread the cable up through the wall from the Electronics Unit, across the air plenum space in the ceiling and down the opposite wall to the chosen location of the Stainless Wall Plate Collector Unit. A 1” to 1.25” hole drilled in each location of wall entry and exit will allow the insulated cable connector to pass through in either direction.

In the event that you are located in a refitted building which does not allow easy access to wall or ceiling interiors, you may have to revert to surface mounting of the cable, but at some point you will have to enter the wall near the collector plate in order to attach to the rear mounted connector. If the wall behind the collector is solid with no access to the interior, give us a quick call and we will exchange an optional wall unit with top-mounted connector to permit surface mounting of cable and collector. If the cable is too short we will similarly exchange for a custom made length of your specification.

A) For standard plaster walls, use the yellow wall anchors and the 1” #8 oval head screws. B) For drywall construction a light duty application will result from the long silver drywall screws. For mounting in a high traffic areas use the large self-drilling inserts which screw directly into the wallboard with a medium Phillips screwdriver. The same #8 oval head screws will then seat into the insert for a solid mount. C) For wood, hard board, or other materials, use either screw as appropriate directly into wall.

If an extension cord is needed to reach the electrical outlet it is imperative for safety and operational reasons that a three-wire appliance cord be used. The unit requires a ground connection in order for the ion level control to function. If no ground connection is present only the “medium” level of ion output will be available and the vapor precipitation efficiency will be impaired. The ground is also required for safety and to minimize static charges on the surface of the unit.

Inside the cabinet at the base of the metal mesh filter is a Safety Interlock Switch which disables the unit when it is not fully depressed. If the mesh filter is removed, or is jarred out of its precise fitting during shipping or handling, the switch will “open” and the unit becomes inoperative.

When the unit is installed, connected to the power outlet and the power switch turned “on”, the indicator light will glow and the silent fan will start up. If they fail to operate, it is likely that the interlock safety switch is not closed due to improper positioning of the metal mesh filter. Simply re- seat the filter so the bottom edge fits snugly atop the metal chassis where the power cord and fuse are located.

Testing the Unit

Testing requires a specialized set of instruments to demonstrate the ion flow. This procedure was carried out for proper operation prior to shipment. If the indicator light is on and the fan is blowing, ions will be flowing.

Caution: High voltage static charges are present

When using any electrical appliance, the following safety precautions should always be followed in order to reduce the risk of fire, electric shock, and/or injury:

1. Do not place cord, plug or any component of the Tact-Air Model 10-8 in water or other liquid. 2. There are no customer-serviceable parts inside the Electronics Unit. Repairs should only be done by authorized personnel. 3. Close supervision is necessary when any appliance is used by or near children. 4. Do not operate the appliance with a damaged power cord or Interconnect Cable 5. Do not use the unit in the presence of explosive and/or flammable fumes
