WELCOME to years of economical comfort
Your new Friedrich Room Air Conditioner has been carefully
engineered and manufactured to give you many years of dependable,
efficient operation, keeping your room at a comfortable temperature
and humidity level. Many extra features have been built into your
Friedrich Room Air Conditioner to assure quiet operation, greatest
circulation of cool, dry air, most flexible selection of function controls,
and high economy of operation.
6. Have a fireplace? Be sure the damper is closed during air
conditioner operation.
7. When it’s time to reroof or repaint the outside of your home,
choose light colors. They reflect heat instead of absorbing it.
8. Shade your outside walls (especially on the west) from the direct
sun; most importantly, shade the unit itself Trees and shrubs
provide natural shading, but make sure they don’t block the air
flow around the unit. If natural shade isn’t present, awnings are
the best solution for shading the unit and the windows. Also,
avoid areas where too much dust or pollen would be drawn
into the air conditioner.
There are many things you can do in and around your home to save
more money - and even increase the efficiency and long life of your
Friedrich unit. Here are a few examples:
1. How to Set Thermostat: When you first turn on your air
conditioner, select the highest fan speed and set the thermostat
to its coldest position to cool the room. When the desired
temperature is reached, turn the thermostat control toward
"warmer" until the compressor goes off. The thermostat
will then cause the compressor to go on and off to maintain
this selected temperature. You can adjust the fan speed for
optimum air circulation.
9. Inside the house, use blinds, screens, or drapes on windows
exposed to the sun. They will reduce your cooling needs.
(Lined or insulated draperies will also help cut heating costs
in winter).
10. Make sure your attic area is properly vented. In addition,
consider installing turbine or power ventilators to help remove
hot air from your attic.
2. Do not block the flow of air to and from the unit - make sure the
louvers are directed to give even distribution of air throughout
the room. Caution: If air is obstructed and/or deflected back
into the air conditioner, this may cause the unit to cycle on and
off rapidly, which could damage your unit.
11. Keep your Friedrich unit clean. Use a vacuum cleaner
attachment for accessible parts, but take care not to damage
them. Clean the reusable filter at least twice a month.
12. Set the thermostat at a higher temperature - save 5% in energy
usage for each degree of temperature over 72°F.
3. Adequate insulation - walls, ceilings, and below floors - can save
up to 50% of the cost of cooling in most areas of the country.
These are the most important suggestions for saving money on
cooling costs. Some, however, may not be applicable to your house
or area. Check with your local utility company for more specialized
information.
4. Caulking: in well insulated homes, air leaks around doors,
windows, lighting and plumbing fixtures can account for as
much as 30% of the load on heating and cooling systems. See
that all these areas are well caulked.
5. Install weather stripping (metal is preferable to felt) around
exterior doors and windows.

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.
FILTER ACCESS - Remove the INTAKE GRILLE from the
DECORATIVE FRONT frame by grasping it at the upper right and
left side corners. Pull out until the GRILLE is released from the upper
retaining snaps. Tilt down toward you, lift 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 front up and away from you. Press in lightly on top and the
GRILLE will position itself into the upper retaining snaps.

How to change airflow direction
Electrical requirements
The DISCHARGE GRILLE is installed at the factory to provide 45˚
upward airflow into the room. (Direction 1 in Figure 5). If a vertical
airflow is desired (Direction 2), the direction can be changed by rotating
the DISCHARGE GRILLE.
IMPORTANT: Before you begin the actual installation of your air
conditioner, check local electrical codes and the information 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
3 and 7 for the correct type of receptacle for your model.
Unplug the air conditioner.
Remove the DISCHARGE GRILLE RETAINER attached with one
screw in the right side of the grille.
An overloaded circuit will invariably cause malfunction or failure of an
air conditioner, therefore, it is extremely important that the electrical
power and the wiring is adequate. Consult your dealer or power
company if in doubt.
Remove the DISCHARGE GRILLE from the retaining slots near the
CONTROLS, and rotate the grille as shown in Figure 5.
Reinstall the DISCHARGE GRILLE by placing it in its retaining slots.
Reattach the DISCHARGE GRILLE RETAINER with the retaining
screw. The unit is now ready to operate.
CIRCUIT PROTECTION - Before 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 for 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.
How to cover inner weather panel holes
Two beige plugs are included in the plastic bag taped to the WallMaster
chassis. These plugs may be used to cover the two holes left after
removing the inner weather panel (see Figure 5). The plugs must be
attached before the DECORATIVE FRONT frame is installed.

Never use an extension cord
Once plugged in the unit will operate normally without the need to
reset the LCDI device.
Your Friedrich room air conditioner is equipped with a three-prong
(grounded) plug for your protection against shock hazards and should
be plugged directly into a properly grounded three-prong receptacle.
If you have a two-prong receptacle you will need to have the circuit
replaced by a certified electrician with a grounded circuit that meets
all national and local codes and ordinances. Under no circumstances
should you remove the ground prong from the plug. You must use the
three-prong plug furnished with the air conditioner.
If the device fails to trip when tested or if the power supply cord
is damaged it must be replaced with a new supply cord from the
manufacturer. We recommend you contact our Technical Assistance
Line at (800) 541-6645 ext. 662. To expedite service, please have your
model and serial number available.
NEVER CUT OR REMOVE THE GROUNDING PRONG FROM THE
PLUG.
NOTE: Your LCDI device will resemble one of these illustrations.
Power cord information
All Friedrich room air conditioners are shipped from the factory with
a Leakage Current Detection Interrupter (LCDI) equipped power
cord. The LCDI device meets the UL and NEC requirements for cord
connected air conditioners effective August 2004.

Troubleshooting tips and home maintenance
Won’t cool
Frosting of the indoor coil
If the unit operates, but won’t cool, determine if the controls are
properly set. Wait three minutes before setting the thermostat 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.
Check to see if the chassis seal gasket is properly installed (refer to
page 14 for seal gasket installation).
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
thermostat to a slightly warmer position will probably keep the coil
from frosting over again.
Won’t heat (for heat/cool models only)
If the unit operates, but won’t heat, determine if the control settings are
correct. Adjust the thermostat to a warmer position to determine if it
operates. Also, check the filter and clean it thoroughly, if needed.
Cleaning the decorative front
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 efficient
operation. Your Friedrich dealer should be called when this service
is required.
Odors in heating (for heat/cool models only)
You may notice a smoke odor the first time the heater element comes
on. This is common in any type of heat system when first 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 firmly
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 pages 4 and 7 in these instructions. After restoring
the current supply to the unit, wait three minutes before restarting.
Things to know about a WallMaster heat pump
During the heat pump operation, you may notice some functions that did not occur when the unit was used for cooling:
1. It is common for ice to form on the outdoor coil of your WallMaster Heat Pump. The ice forms due to moisture in the outdoor
air passing over cold (below freezing) coil surfaces.
2. When the outdoor coil forms ice, your heat pump will automatically initiate a defrost. The compressor will stop and the fan will
continue to run. The electric heat will be turned on to continue warming the room while the outdoor air defrosts the outdoor
coil. After the defrost is completed, the unit will automatically return to the heat pump mode.
3. It is normal for vapor (steam) to rise from the outdoor coil during the defrost. This is similar to expelling warm breath on a
cold morning.
4. If the outdoor temperature drops below 43°F during heat pump operation, your WallMaster Heat Pump will automatically
switch to electric resistance heat and will continue to operate in this mode as long as the outdoor temperature remains at
43°F or below.

from the lower right side corner and extending over the
top and down to the lower left side corner. Then push the
chassis all the way into the shell for the remaining distance
so that the plastic front meets the front edge of the shell.
If chassis seal gasket is not installed, the operation of the
unit will be negatively affected. Also, the operation noise
and outside noise will be amplified.

Condensate removal (WS, WE and WY models)
If you desire to drain condensate from the basepan during unit
operation, this unit is provided with a drain nipple that can be
attached to the basepan. You must provide a 3/8" outside diameter
thin-wall plastic or copper tube which will attach to the drain nipple.
Follow the instructions below:
STEP 2
Remove the knockout in the lower right side of the rear
grille. Slide the chassis into the WSC SLEEVE so that
the drain nipple extends through the knockout.
STEP 3
Slide the tubing inside the drain nipple.
STEP 1
Find the drain plate on the rear of the basepan and
remove it. (See Figure 12).
If the chassis must be removed from the sleeve for service, remove
the clamped drain hose before sliding the chassis out of the sleeve.

DK (Drain Kit)
IDK (Interior Drain Kit)
New construction allowing for condensate drain systems built within
the walls can use the Friedrich Interior Drain Kit (Accessory #IDK)
designed for installation in the bottom of the sleeve below the
condensate bellows valve (heat/cool models only).
In the event that the outdoor temperature drops below 37°F, any water
that remains in the chassis basepan is drained into the sleeve pan on
WE and WY models to prevent freezing. (NOTE: In the cooling mode
of the WS, WE and WY models, condensate overflow is possible in
very humid climates). For these particular instances, an optional drain
kit (Accessory #DK) is available for water removal.
