ELECTRICAL
The air cleaner unit has an air flow sensor installed. There-
fore, control wiring is not required.
FURNACE & AIR HANDLER - 120 VAC models
These models require a 3 prong, grounded, 120 VAC outlet
with a minimum circuit protection of 15 amps. A power cord
is shipped with the air cleaner that matches the 120 VAC
input to the air cleaner and the 3 prong, grounded 120 VAC
outlet. Plug the power cord into the receptacle below the
switch on the air cleaner power door and to power source
outlet.
DO NOT REMOVE THE GROUNDING PIN FROM THE POWER
CORD!
AIR HANDLER - 240 VAC models
These air cleaner models are designed to be connected to 240
VAC using the power cord and polarized connector adapter
shipped with the air cleaner as follows:
1.Install the polarized connector end of the power cord,
supplied with the electronic air cleaner, into the air
handler through the front lower right electrical knock out
using the attached strain relief connector. See Figure 8.
2.Plug the power cord into the receptacle below the switch on
the air cleaner power door.
3.Connect the power cord polarized connector to the three
wire plug on the polarized connector adapter.
4.Connect the six pin polarized connector on the adapter
between the female polarized connector on the heater and
the male polarized connector from the air handler control
box. See Figure 8. The polarized connectors are keyed to
aid in preventing incorrect assembly.
NOTE: If no accessory heater is installed, install the plug
adapter between the polarized connector on the junction box
and the polarized connector from the air handler control
box.
5.Connect the green ground wire on the plug adapter to the
air handler ground located on the left heater barrier
between the heater and the cabinet. See Figure 8.
Install strain relief, included
with power cord, here.
Connect green ground
lead from adapter to air
handler cabinet ground.
If no accessory heater is
installed, mate this plug with
the polorized connector mounted on
the electrical junction box.

5.
Check that the front of the air cleaner cabinet is facing
the front of the unit.
6.
Securely attach the air cleaner cabinet to the unit using
the heavy-duty self-tapping sheet metal screws provided.
It is recommended that sheet metal turning vanes be
installed inside an elbow on ductwork attached to the
entering airstream side of the air cleaner. This improves the
air distribution over the cells. (See Fig. 7.)
Use transition fittings where return air duct dimensions do
not match the air cleaners opening dimensions. Gradual
transitions are preferred for greatest efficiency. Four inches
per linear foot (approximately 20° angle) should be allowed,
space permitting.
7.
Seal all joints in the return air system to prevent dust
from entering the airstream.
NOTE: Do NOT use a silicon base sealant. This causes a
coating on the ionizing wires that will decrease the efficiency
of the Air Cleaner.
8.
Reinstall the pre-filter, collecting cells and power door.
