Filters
One of the most common causes of a problem in a forced air
cooling systems is a blocked or dirty filter
be inspected monthly for dirt accumulation and replaced if
necessary.
Filters must always be used and must be kept clean. When
filters become dirt laden, insufficient air will be delivered by
the blower, decreasing your unit's efficiency and increasing
operating costs and wear and tear on the unit and controls.
This unit is not equipped with a filter or filter rack. A factory
filter kit (Part Number 194807830001) may be ordered from
Fedders distributor. If a non-factory filter is used, the filter
MUST have a pressure drop of less than 20pa.
WARNING
DO NOT OPERATE UNIT WITHOUT AN AIR FILTER.
WARNING
DISCONNECT THE ELECTRICAL POWER TO THE UNIT
BEFORE ATTEMPTING ANY MAINTENANCE. FAILURE TO
DO SO MAY CAUSE ELECTRICAL SHOCK RESULTING IN
SEVERE PERSONAL INJURY OR DEATH.
Consult your installation contractor or service technician if
you have any questions regarding filters.
Routine Examination
It is good practice to give a quick inspection each time you
inspect or clean the air filter.
Things to check:
• All areas around the air openings should be clear and
free of obstructions.
• Check the venting to ensure that it is still fastened to the
unit. It should be physically sound, without holes or
excessive corrosion.
• The return air duct connection must be sound and
securely fastened.
• All ductwork should be secure, and all ductwork should
be solidly supported throughout the heating system.
• The unit should be well supported. Base support should
be physically sound without sagging, cracks, gaps, etc.
• Check for obvious signs of deterioration.
Cleaning
It is advisable to keep dust buildup on warm surfaces to a
. Air filters should
minimum, since dust, in some cases, can be combustible.
Dust buildup in the circulating fan can impair blower
performance; therefore, reduce efficiency. Because the
blower wheel is fastened directly to the blower motor, we
recommend that major cleaning be left to your service
contractor.
