How to cleanthe air filter
Your Friedrich Room Air Conditioner is equipped with a
Pernaalbam reusable air filter with a germicidal treatment,
which is not affected by washing. The filter serves to remove
dust, pollen, and other impurities flom the air.
KEEP THE FILTER CLEAN - A clogged, dirty filter will
reduce the operating efficiency of your unit and contribute to
frosting of the indoor coil. Be sure to check the filter every 7 to
10 days. The filter check procedure is easy, due to the unique
design of the Friedrich DECORATIVE FRONT.

upper right and left side comers. Pull out until the GRILLE
is released from the upper retaining snaps. Tilt down toward
you, lilt up and out of the bottom retaining snaps. This will
expose the filter. Remove the filter by pulling it toward you.
Wash the filter in hot, soapy water, rinse, squeeze lightly to
remove excess water, shake dry - do not twist - and replace
in the unit on the two support hangers. Replace the INTAKE
GRILLE by positioning the bottom of the GRILLE into the
bottom retaining snaps. Tilt the flout up and away flom you.
Press in lightly on top and the GRILLE will position itself into
the upper retaining snaps.

Electricalrequirements
IMPORTANT: Betbre you begin the actual installation of
your air conditioner, check local electrical codes and the
iulbrmatiou below.
Your air conditioner must be connected to a power supply
with the same AC voltage and hertz rating as marked on the
nameplate located on the chassis. Only alternating current
(AC) can be used. Consult pages 2 and 5 lbr the correct type
of receptacle lbr your model.
An overloaded circuit will invariably cause malfunction
or failure of an air conditioner, therelbre, it is extremely
important that the electrical power and the wiring is
adequate. Consult your dealer or power company if in doubt.
CIRCUIT PROTECTION - Belbre installing or relocating
your Friedrich Room Air Conditioner, check the amp rating
of the circuit breaker or "TIME-DELAY" fuse. Refer to the
nameplate located on the air conditioner chassis to determine
the correct fuse or circuit breaker amperage lbr your model.
The rating MUST NOT exceed the value stated on the
nameplate. If the air conditioner is connected to a circuit
protected by a fuse, a "TIME-DELAY" fuse must be used
due to the momentary high current demands when your air
conditioner is started.
