Wiring
For the wiring in the furnace and fan coil wiring
compartments
The incoming power supply wiring and connections for the air
purifier should be routed away from the output duct of the furnace
or fan coil unit, and the incoming power connections for the air
purifier in the furnace or fan coil unit must be properly rated. The
maximum rated current draw for the furnace 120VAC and fan coil
230VAC air purifiers is 0.3 Amps.
The installation involves direct connection to the duct and to a
furnace controller EAC terminal output. The field wiring
connection shall be suitable for a maximum possible rating of
90
_
C of the field wiring terminal box/terminals.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing or servicing system, always turn off main
power to system. There may be more than one disconnect
switch. Lock out and tag switch with a suitable warning label.

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. Voltages can exceed 190 VAC (120v motors). Do not
wire directly to blower motor. Wiring to blower motor will
damage power supply and void warranty.
CAUTION
!
1. Ensure power has been removed from the heating and cool-
ing system.
2. Turn the Air Purifier power switch off.
For mounting on furnaces:
1. Route the power conduit from the purifier to a knockout on
the furnace that provides access to the EAC terminals on the
furnace control board. Affix the end of the conduit to the
furnace using the included conduit fitting.
2. Attach the quick connect terminals on the wires exiting the
power conduit assembly to the furnace EAC--1 and EAC--2
spade connections. Attach the ground ring terminal on the
third wire to furnace chassis ground. See Fig. 11 and 12.
NOTE
: The Air Purifier should only be powered when airflow is
present. The furnace control EAC spade connections, shown in
Fig. 12, provide power only when the furnace blower is operating.
Air Purifier models PGAPAXX1625 and PGAPAXX2025 are
designed to be powered from the electronic air cleaner (EAC)
terminals on a furnace electronic control. If EAC terminals are not
available, the Accessory Flow Sensor Kit, model KIT--160--000,
must be purchased for use with the Air Purifier.
