Wiring
For the wiring in the furnace wiring compartment
The incoming power supply wiring and connections for the Return Air
Purifier should be routed away from the output duct of the furnace, and
the incoming power connections for the Return Air Purifier in the
furnace must be properly rated. The maximum rated current draw for the
furnace 120VAC Return 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 shall be copper
conductors only, suitable for a maximum possible rating of 90°C of the
field wiring terminal box/terminals.
For wiring from the unit to the furnace:
1. Route a wire or power conduit (depending on local codes) from the
purifier electrical box to a power supply disconnect located within 6
feet of the unit; then from the disconnect to a knockout on the
furnace that provides access to the EAC terminals on the furnace
control board. Affix the ends of the wire or conduit to the furnace
and electrical box with proper UL rated fittings.
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 ( Fig. 15 and Fig. 16 ).
NOTE: The Return Air Purifier should only be powered when airflow is
present. The furnace control EAC spade connections, shown in Fig. 16 ,
provide power only when the furnace blower is operating. Return Air
Purifier RGAPAXX1625 is designed to be powered from the electronic
air cleaner (EAC) terminals on a furnace electronic control.
For wiring from the unit to the furnace:
1. Route a wire or power conduit (depending on local codes) from the
purifier electrical box to a knockout on the fan coil air handler that
provides access to the incoming power wiring compartment. Affix
the ends of the wire or conduit to the fan coil unit and electrical box
with proper UL rated fittings.
2. Remove the yellow and black primary wires from the fan coil air
handler transformer terminals and connect the quick connect
“piggyback” terminals of the quick connect kit leads exiting the air
purifier power conduit assembly to the transformer terminals.
Reconnect the yellow and black primary wires to their respective
transformer terminals on the “piggyback” terminals. Attach the
ground ring terminal on the third wire to fan coil air handler chassis
ground ( Fig. 15 ).
NOTE: Power connections are to be made inside the fan coil wiring
compartment per local electrical codes, and the two in-line fuses that are
provided with the air purifier must be installed in the fan coil wiring
compartment.

WARNING
!
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.
CAUTION
!
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.
