A.
Route the power conduit from the purifier to a knockout on the fan coil air
handler that provides access to the incoming power wiring compartment.
Affix the end of the conduit to the fan coil air handler using the included
conduit fitting.
B.
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 the fan coil air handler chassis ground.
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.
For Fan Coil Purifiers: Black Lead − connect to L1; White Lead − connect
to L2; Green Lead − connect to Appliance Ground (Chassis).
A.
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.
B.
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.
Note:
The Air Purifier should only be
powered when airflow is present.
The furnace control EAC spade
connections, shown in image at left,
provide power only when the furnace
blower is operating.
