Filter Information
The filter in your Friedrich removes dust, pollen and other
impurities from the air as they are drawn through the unit.
The filter is permanent and reusable, and has a germicidal
treatment which is not affected by washing.
Won’t Cool
If the unit operates, but doesn’t cool, check to see that the con-
trols are properly set. Inspect the filter and clean it thoroughly, if
needed. Check to see if the chassis seal gasket is installed (refer
to installation instructions).
Won’t Run
If the unit does not operate at all, check that the power supply
connections are tight. Check for blown fuses or tripped circuit
breakers. Replace blown fuses with the proper size time-delay
fuse. The nameplateon theunit shows the proper fuse size. After
restoring power, wait three minutes before restarting the unit.

Cleaning
The front grille of your Friedrich, as well as the complete cabi-
net may be cleaned with warm water and a mild detergent. The
coils and base pan should be cleaned periodically for the most
efficient operation. We suggest you call your Friedrich dealer
for th
is service.
Lubrication
Fan motors are factory lubricated and sealed. No lubrication
is required.
A clogged, dirty filter reduces the air flow through the unit and
reduces its efficiency. You should check the filter every seven
to ten days, depending on the amount your unit is used. Clean
the filter regularly.
