Surge resistor is an integral part of the new power supply. 4. Install proper length bus bar. 5. Route wires so they will not contact high-voltage circuit and install wire clip. 6. Reinstall power door in air cleaner. 7. Turn on main electrical supply to the air cleaner and air handler. 8. Check air cleaner for proper operati

It may be necessary to adjust individual fan wheels or move entire fan shaft. See the following two sections. Fan Shaft Position Adjustment — Loosen setscrew or locking collar of each fan shaft bearing. Slide

Remove screw holding contact spring to cells and reinstall at opposite end (See Fig. 17). Be sure all airflow arrows are pointing in the direction of the airflow through the air cleaner and that the prefilters are on the entering-air side. 3. Deform prefilter guide on side opposite prefilters so that prefilters may not be reinstalled incorrectly. 4. Replace power door by first inserting bottom tab into place on bottom edge of door opening. Push top of door and guide door attachment knob screw

When outdoor air is added, make certain that it is far enough ahead of the air cleaner to be mixed and warmed properly. If not, baffles must be installed to force mixing of the air. 2. Preheat coil. If a large amount of outdoor air is used, it must be heated. A thermostat should be used to control the heater. (A strip heater or hot water coil are typical heaters.)

See Power Door. 2. Disconnect surge resistor at power supply. 3. Remove screws holding the bus bar. Cell — Plate-type and media-type, Fig. 14. The cell contains the ionizer wires, the ionizer ground plate, Fig. 15, item 1, and the charged and grounded collector plate assembly, item 3, of the plate-type cell. The plate-type and media-type cleaners are the same electrically. Physically, however, while the media-type cell has the same type of ionizer as the plate-type, a fiber glass pad between

If an atomizing humidifier must be mounted upstream of the Infinityt Air Purifier, it should be mounted as far upstream as possible (at least 6 ft. recommended), and a standard disposable furnace filter should be mounted between the humidifier and the air purifier to trap hard water salt deposits and water droplets. Transitions If the return air duct or fan coil openings do not fit the Infinityt Air Purifier cabinet openings, gradual transitions are recommended to reduce air turbulence and maxim

Before installing or servicing system, always turn off main power to system. There may be more than 1 disconnect switch. ! WARNING EQUIPMENT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. This unit cannot be powered directly from blower motor leads. Do not wire directly to blower motor. Wiring to blower motor will damage power supply and void warranty. ! CAUTION A06414 Fig. 7 --- Flow Sensor Cable Installed A06413 Fig. 8 --- Power Cord Installe
