AIR CONDITIONING
Whenever possible, your Air Cleaner should be installed
upstream of the cooling coil. This will clean the air before
it reaches the evaporator coil.
GENERAL INSTALLATION STEPS
1.
Remove existing equipment filter and clean
blower compartment:
Thoroughly clean the blower
compartment since your Air Cleaner cannot remove
dirt from the blower chamber and distribution ducts.
2.
Leave sufficient room around your Air Cleaner:
There must be adequate room to remove the filter.
NOTE:
Once your Air Cleaner has been installed, do
not allow the placement of a new hot water heater,
water softener, gas pipe, or electrical cable to be put
in front of or within 12 in (30 cm) from the top of the
Air Cleaner. Otherwise, this will not allow for the
removal of the Air Cleaner filters, which are necessary
for maintenance or upgrading later.
3.
Installing the cabinet:
Make sure rivets or screws
do not protrude into the cabinet, causing filters to
catch.
4.
Transitions:
When the air duct does not fit the Air
Cleaner opening, a gradual transition is
recommended to reduce air turbulence through the
Air Cleaner and to increase its efficiency. There
should not be more than 20
o
of expansion used on
each side of the transition fitting, approximately 4
inches per running foot (10 cm per 30 cm).
Do not reduce ductwork to fit a smaller Air
Cleaner. This will increase the velocity of air flow
and may decrease cleaning efficiency.
5.
Turning vanes:
If the Air Cleaner is installed
adjacent to an elbow or angle fitting, turning vanes are
recommended to improve air distribution across the
filter.
6.
Seal the joints in the return air system:
All joints
between the Air Cleaner and the heating/cooling
equipment should be sealed to prevent dust from
entering the clean air stream.
To improve the performance of your Air Cleaner,
these simple steps should be followed:
•
Run your heating/cooling system fan continuously, on
low speed if available, since your Air Cleaner only
removes particulate matter which passes through to
the filter.
•
Remove furniture or carpets from the front of the
return air grilles so that air moves freely to the
heating/cooling equipment.
•
Check the fan belt on the furnace blower and see that
there is no more than approximately 1/2 in (1.3 cm) of
play on each side. A loose belt slips on the pulley.

MAINTENANCE
CAUTION
Turn off your heating/air conditioning system fan before
performing maintenance to your Air Cleaner.
The MERV 11 Media Filter needs to be replaced once or
twice a year, depending on amount of contaminants in air
.
Use original manufacturer’s filter only to avoid
damage to your furnace or air handler. These filters
are Perfect Fit.
Use of improper or generic filters can
cause dust load build up on motor, blower and coils of
your heating and cooling system, which can lead to higher
energy consumption and failure of HVAC equipment. A
clogged filter may cause a restriction to the air flow
through the system. This may cause poor circulation of
conditioned air or the evaporator coil to freeze.
1. Remove Air Cleaner door.
2. Remove filter and discard.
3. Install Original Manufacturer’s Filter per below.
4. Arrow must point toward the system fan.
5. Close Air Cleaner door.
