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,  
efcient 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 exible selection of function controls,  
and high economy of operation.  
6. Have a replace? 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 reect 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  
ow 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 efciency and long life of your  
Friedrich unit. Here are a few examples:  
1. How to Set Thermostat: When you rst 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 ow 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 deected 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 lter 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 oors - 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 xtures 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.

Press the Smart Fan button to activate the Smart Fan. The light  
will indicate that this feature is in use.  
Smart Fan will adjust the fan speed automatically to maintain the  
desired comfort level. For example, if the outside doors in your home  
are opened for an extended period of time, or more people enter a  
room, Smart Fan may adjust to a higher fan speed to compensate  
for the increased heat load. This keeps you from having to adjust  
the fan speed on your own.

KEEP THE FILTER CLEAN - A clogged, dirty lter will reduce the  
operating efciency of your unit and contribute to frosting of the  
indoor coil. Be sure to check the lter every 7 to 10 days. The lter  
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 lter. Remove the lter by pulling  
it toward you. Wash the lter 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 airow into the room. (Direction 1 in Figure 5). If a vertical  
airow 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 certied 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 lter 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 lter 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 lter 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 efcient  
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 rst time the heater element comes  
on. This is common in any type of heat system when 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 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 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.

Sleeve installation  
STEP 1 After unpacking the WSC SLEEVE from the carton, remove  
the corrugated FRONT PANEL. Place the WSC SLEEVE  
in the wall opening following the instructions given in the  
INSTALLATION REQUIREMENTS. Attach the SLEEVE to  
the INSIDE WALL by driving two #12A x 2" screws in each  
side of the SLEEVE (see Figure 7). Shim at the top of the  
SLEEVE, midway between the sides. Drive one #12A x 2"  
screw in the top of the sleeve, close to the shim. Install  
screws from inside the SLEEVE. If the wall opening is not  
framed with wood, use expansion anchor bolts or molly  
(toggle) bolts (not provided).  
STEP 2 Once the SLEEVE has been installed, check the LEVEL  
again to be sure the ½ bubble downward tilt is maintained.  
Apply shims, if required, to maintain the proper slope.  
STEP 3 Caulk the perimeter of the entire opening on the inside and  
the outside between the SLEEVE and the WALL.  
STEP 4 The corrugated front panel removed in Step 1 above must  
be remounted back in place if masonry work is to be done  
and/or if the "WallMaster" CHASSIS is to be installed at a  
later date.

WallMaster chassis installation instructions for WS, WE and WY models  
(WSC-A sleeve)  
These instructions are provided for installation of WallMaster air  
conditioner chassis models into thru-the-wall sleeves. This chassis  
has been UL approved with the sleeve listed on the serial nameplate  
of this chassis. Important warranty information is provided on pages  
17 and 18. Keep these instructions in a convenient location for any  
warranty service that may be required.  
STEP 2 Check the electrical receptacle to see that it conforms to  
the requirements for the chassis model to be installed.  
See pages 2 and 5, for the receptacle requirements.  
STEP 3 The decorative front is packaged in a separate box inside  
the chassis shipping carton, between the chassis and  
the carton. Remove this box and set the box aside until  
later.  
STEP 1 Check the sleeve to be certain it has been correctly installed  
in the wall. Remove the corrugated front panel on the WSC  
SLEEVE. Remove the rear WEATHER PANEL. Reverse  
grille. Place lower edge into sleeve tab (Friedrich logo facing  
out). Align slots with screw holes. Secure grille with screws.  
STEP 4  
With the help of an assistant, remove the chassis from  
the shipping carton. Be careful not to allow anything to  
impact against the hairpins as this may result in damage  
to them. With the help of an assistant, lift the chassis by  
the basepan and slide it into the sleeve until it contacts  
the rear grille. With the chassis in proper position, the  
front edge of the basepan must extend out 4 ¾ inches  
from the front (side) edge of sleeve.  
A. Check the anchor screws. There should be four  
(4) in the WSC SLEEVE (two in each side).  
B. Determine if the sleeve has a downward slope,  
to the outside, of ½ bubble on a level. See  
page 10 for further details.  
C. Check to be sure the sleeve has been sealed  
around all edges with an industrial type  
caulking on both the outside and inside to  
prevent rain entry.

WallMaster chassis installation instructions for WS, WE and WY models  
(WSC-B sleeve)  
These instructions are provided for installation of WallMaster air  
conditioner chassis models into thru-the-wall sleeves. This chassis  
has been UL approved with the sleeve listed on the serial nameplate  
of this chassis. Important warranty information is provided on pages  
17 and 18. Keep these instructions in a convenient location for any  
warranty service that may be required.  
STEP 2 Check the electrical receptacle to see that it conforms to  
the requirements for the chassis model to be installed.  
See pages 2 and 5, for the receptacle requirements.  
STEP 3 The decorative front is packaged in a separate box inside  
the chassis shipping carton, between the chassis and  
the carton. Remove this box and set the box aside until  
later.  
STEP 1 Check the sleeve to be certain it has been correctly installed  
in the wall. Remove the corrugated front panel on the WSC  
SLEEVE. Remove the rear WEATHER PANEL. Place lower  
edge into sleeve tab (Friedrich logo facing out). Align slots  
with screw holes. Secure grille with screws.  
STEP 4  
With the help of an assistant, remove the chassis from  
the shipping carton. Be careful not to allow anything to  
impact against the hairpins as this may result in damage  
to them. With the help of an assistant, lift the chassis by  
the basepan and slide it into the sleeve until it contacts  
the rear grille. With the chassis in proper position, the  
front edge of the basepan must extend out 4 ¾ inches  
from the front (side) edge of sleeve.  
A. Check the anchor screws. There should be four  
(4) in the WSC SLEEVE (two in each side).  
B. Determine if the sleeve has a downward slope,  
to the outside, of ½ bubble on a level. See  
page 10 for further details.  
C. Check to be sure the sleeve has been sealed  
around all edges with an industrial type  
caulking on both the outside and inside to  
prevent rain entry.

STEP 5 CHASSIS SEAL GASKET INSTALLATION: After  
STEP 6 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 it down toward you, lift up and out of the bottom retaining  
snaps. Install the decorative front frame in place over the  
sleeve opening and attach it to the chassis with four sheet  
metal screws as shown in Figure 11. 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 upper  
retaining snaps.  
installing the shell, slide the chassis into the shell stopping  
approximately 3" from full insertion. Stuff the chassis seal  
gasket one inch deep between the chassis and the shell  
(see Figure 11). Make sure the gasket is installed beginning  
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 amplied.

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.

Alternate drain kits  
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 overow is possible in  
very humid climates). For these particular instances, an optional drain  
kit (Accessory #DK) is available for water removal.
