Remove Existing Electrical Hardware:
Identify the existing air cleaner located in the return air
duct of a central forced-air furnace/air handler. The air
cleaner is typically installed as shown in Figure 6.
FURNACE AND AIR HANDLER - (120 VAC models):
If the existing air cleaner is an electronic type Perfect
Fit™ air cleaner filter (EAC), switch the POWER button
to the “OFF” position. All furnace applications, and
some air handler applications use 120 VAC 3 prong

electrical outlet.
AIR HANDLER - (240 VAC models):
If the EAC is internally wired into the air handler, the
power cord and polarized connector adapter will need to
be removed from the air handler system.
1. Disconnect the strain relief connector. See Figure 14 to
the right.
2. Remove the six pin polarized connector on the adapter
located between the female polarized connector on the
heater and the male polarized connector from the air
handler control box. See Figure 14.
3. Reconnect the female polarized connector on the heater
and the male polarized connector from the air handler
control box.
