Warning:
Instructions listed for interlocking the
filtration unit to a furnace is an example
only. Actual wiring of interlock connection
may vary depending on the system
Wiring the AC500 Air Cleaner
to an ICP 80% or 90 % +%Furnace
The wiring together of the GeneralAire AC500 Air cleaner onto an ICP electronic fan
control (EFC) board is as simple as 1-2-3. Control boards on different brands of
furnaces vary but in principal are all quite similar.
Step 1:
Turn-off electric power to furnace and use a
120V coil SPST N/O relay (such as the Relay-
In-Box #RIBU1C L39-103). Mount relay to a _
knockout.
Step 2:
Wire the HOT EAC terminal on the furnaces
EFC board to one side of the 120V coil on the
relay. Wire the other side of the 120V coil
back to a spare common terminal on the EFC
board.
Step 3:
Wire 120V HOT from blower door safety
switch (use a spade terminal splitter similar to
Johnstone #G21-414) to one side of the open
contact on the relay (red wires on L38-180).
Wire from the relay to a receptacle you
mount in a 2X4 handy-box on the outside of
the furnace. Wire the common side of the
receptacle to the common terminal on the
furnace EFC board. 4. General Maintenance Information

Function
The Whole House HEPA system is comprised of a ventilator, speed selection
switch, 3 stages of filtration and the cabinet enclosure system. The ventilator
pulls air through the pre-filter and pushes the same air threw the impregnat-
ed carbon pad for odor control and finally the last stage of filtration is the HEPA
filter which removes 99.97% of particles 0.3µm in size.
Operation Mode Options
The unit features two speeds of operation for your convenience. The speed
selection switch is located on the front of the motor assembly. At lowest speed
the unit will provide 220 CFM of clean air while at highest speed, the unit will
provide 300 CFM of clean air. It is recommended that the unit be operated on
highest speed at all times to maximize the benefits of the HEPA filtration
system. If for some reason the filtration needs are not as important then one
might operate the unit at low speed.
An access door is provided at the front of the unit
to permit access to the filters and speed selection
switch. Opening the latch on the right side of the
unit will permit the door to swing open. A safety
door interlock switch cuts the power to the motors
for your safety. If needed the door can be removed
from the cabinet hinges by holding the top part of
the door with one hand and gently taping on the
bottom edge of the door with the other hand to
release the door from its hinges.
Recommended Operation
The return plenum mount model operates in conjunction with your forced air
heating/cooling system. A forced air distribution system continuously
circulates the same air inside your home. The whole house HEPA filtration
system operates on the principal of bypass filtration, which means that a
portion of the air being returned into the furnace is filtered on each pass. Over
time all the air in the home gets cleaned. It is recommended that the furnace
blower be in operation whenever the filtration system is in operation.
For stand-alone attic installation, the HEPA filtration system must be
operated continuously whenever a part of all the system is located in an
unconditionned space to avoid condensation in the ductwork below freezing
(32°F ,0°C)
Maintenance of the unit should be performed at regular interval to keep the
benefits of the HEPA filtration unit.

System
installation
The Whole House HEPA Filtration system is
designed to install directly onto the return
air plenum of the forced air heating/cooling
system. Choosing this type of installation
eliminates the need to externally duct the
HEPA filter unit to the plenum system. If you
choose this type of installation, it is
recommended that you run the fan on your
forced air system continuously to maximize
its cleaning ability.
TIPS
to installer
The Whole House HEPA Filtration system
does not replace the filter from the forced
air heating/cooling system. Regular
maintenance of this filter is necessary to
permit the good operation of the forced air
heating/cooling system.
Optional collar

installation
Using kit no. CMK500 the Whole House

use 8 inch round collars for application
requiring ducting. The kit includes two, 8
inch round collars, two mounting brackets
for wall or floor mounting, installation
guide and fasteners.
