Troubleshooting tips and
home maintenance
Won't cool
If the unit operates, but won't cool, determine if the controls are
properly set. Set the thermost to a cooler position in order to check
control settings. Check the filter and clean it thoroughly, if
needed. Check to see if the vent door is closed.
Won't heat (for heat/cool models only)
If the unit operates, but won't heat, determine if the control settings are
o c e r r . t c d A u j t s h t t e e h m r s o t a t
operates. Also, check the fi e t l
Odors in heating (for heat/cool models only)
You may notice a smoke odor the fi rst time the heater element comes
on. This is common in any type of heat system when fi rst turned on
for the winter. The odor comes from dust and other particles that
accumulate during the warm months. The odor will dissipate quickly.
Won't run
If the unit fails to operate, check to see if the power cord is fi rmly
plugged in. Check for blown fuses, tripped circuit breakers or a
tripped LCDI Device (Refer to LCDI reset instructions in the Power
cord information section). Restore the circuit breaker or replace the
blown fuse with a proper size "TIME-DELAY" fuse. The proper fuse
size is shown on page in these instructions. After restoring the
3
current supply to the unit, wait three minutes before unit will restart.
Certain operating conditions may produce indoor coil frost. During
the cooling operation, a dirty filter or restricted air distribution in
combination with cool, damp weather could cause such an occurrence.
Should the indoor coil frost over while cooling, set the control to FAN
and keep it running until the frost on the coil is gone. Setting the
ther mo stat to a slightly warmer position will probably keep the coil
from frosting over again.
The decorative front of your Friedrich room air conditioner, as well
as the complete cabinet, may be cleaned with warm water and mild
detergent. Under adverse operating conditions, the indoor and outdoor
coils and base pan may require periodic cleaning to maintain eficient
operation. Your Friedrich dealer should be called when this service
is required.

STEP 1
The wall opening required for a WSE SLEEVE is 17 ¼"
high by 27 ¼" wide.
STEP 2 LINTELS must be used in opening of brick veneer and
masonry walls to support the material above the WSE
SLEEVE. The following considerations should also be given:
A. A minimum distance of 1" must be allowed on all sides of the unit
to adjacent wall and floor. Where the subbase is required, the
minimum distance from the floor to the sleeve must be 3 ½".
To minimize chances of short cycling of the compressor, the
minimum clearance between the ceiling and the top of the unit
should be 24".
B. Adjustable SUBBASE (SB) or other unit support must be provided
for panel wall type construction and for walls less than 8" thick.
