Installation & Operation Instructions
For WallMaster®"WS", "WE" and "WY" models
WELCOME to years of economical comfort with your new Friedrich Room Air Conditioner.
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.
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.
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.
3. Adequate insulation - walls, ceilings, and below floors - can save up to 50% of the cost of cooling in most areas
of the country.
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.
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.
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.
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.
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.

To start unit
If your air conditioner is installed and plugged into a proper
receptacle, it is ready to go. The first time the unit is started,
the compressor will delay for three minutes. See Automatic
Component Protection, page 3.
1Touch the POWER ON/OFF button once. The unit
will automatically be in COOL with the temperature
set at 75°F (24°C) and the fan speed at F1, the sleep
setting.
To set mode of operation
When you first turn the unit on, it will be in the COOL mode
(light on) with constant fan.
2Touch the MODE button once to activate the
MoneySaver®(light on).
MoneySaver®is a feature that cycles the fan with the
compressor so that the fan does not run all the time. This
saves energy and improves dehumidification. MoneySaver®
will also run to test the temperature if the off cycle is too

How to clean the air filter
Your Friedrich Room Air Conditioner is equipped with a
Permafoam reusable air filter with a germicidal treatment,
which is not affected by washing. The filter serves to remove
dust, pollen, and other impurities from 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.
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 (Figure 6)
The DISCHARGE GRILLE is installed at the factory to
provide 45˚ upward airflow into the room. (Direction 1 in
Figure 6). If a vertical airflow is desired (Direction 2), the
direction can be changed by rotating the DISCHARGE
GRILLE.
Unplug the air conditioner.
Remove the DISCHARGE GRILLE RETAINER attached
with one screw in the right side of the grille.
Remove the DISCHARGE GRILLE from the retaining
slots near the CONTROLS, and rotate the grille as shown
in Figure 6.
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.
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 6). The plugs must be attached before the
DECORATIVE FRONT frame is installed.
Figure 5
Electrical requirements
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 2 and 5 for the correct type
of receptacle for your model.
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.
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.

Never use an extension cord
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.
NEVER CUT OR REMOVE THE GROUNDING
PRONG FROM THE PLUG.
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.
To test your power supply cord:
1. Plug power supply cord into a grounded 3 prong outlet.
2. Press RESET (See Figure 7).
3. Press TEST (listen for click; Reset button trips and
pops out).
4. Press and release RESET (listen for click; Reset button
latches and remains in). The power supply cord is ready
for operation.
NOTE: LCDI device is not intended to be used as a switch.
Once plugged in the unit will operate normally without the
need to reset the LCDI device.
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 [phone] ext. 662. To expedite
service, please have your model and serial number available.

Won’t cool
If the unit operates, but won’t cool, determine if the con-
trols 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 12
for seal gasket installalation).
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.
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 page 7 for LCDI
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.
reset instructions). Restore the circuit breaker or replace
the blown fuse with a proper size "TIME-DELAY" fuse.
The proper fuse size is shown on pages 2 and 5 in these
instructions. After restoring the current supply to the unit,
wait three minutes before restarting.
Frosting of the indoor coil
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.
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.

Wall preparation
STEP 1 The wall opening required for a "WSC" SLEEVE is 17 1/4" high by 27 1/4" wide.
STEP 2 LINTELS must be used in opening of brick veneer and masonry walls to support the material
above the "WSC" SLEEVE. The following considerations should also be given:
A. Adjustable SUBBASE (SB) or other unit support must be provided for panel wall type
construction and for walls less than 8" thick.
B. 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 1/2". To minimize chances of short cycling of the compressor, the minimum clearance
between the ceiling and the top of the unit should be 24". (See Figure 8).

Installation requirements
STEP 1 The "WSC" SLEEVE should be positioned so that the DRAIN EXTENSION extends a
minimum of 9/16" beyond the OUTSIDE WALL (See Figure 8).
STEP 2 The "WSC" SLEEVE must extend a minimum of 7/8" beyond the INSIDE WALL.
STEP 3 The "WSC" SLEEVE must be installed level side to side.
STEP 4 The "WSC" SLEEVE must also be installed with a downward tilt toward the outside of the
building. If a level is placed so that it rests on the FRONT and BACK UNIT REST as shown
in Figure 9, a properly installed unit provides a 1/2 bubble slope to the outside of the building.
CAUTION: SLEEVE projections and leveling precautions must be observed to prevent the
entry of water into the room.
Sleeve installation
STEP 1 After unpacking the "WSC" SLEEVE from the carton, remove the unpainted FRONT PANEL.
Locate 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 8). 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 1/2 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 unpainted 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
"WS", "WE" and "WY" models
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 14 and 15. Keep these instructions in a convenient location for any warranty service that may be required.
STEP 1. Check the sleeve to be certain it has been correctly installed in the wall. Remove the unpainted front
panel on the "WSC" sleeve. Remove the rear WEATHER PANEL. Leave the rear grille in place.
Discard the other items taken out.
A. Check the anchor screws. There should be five (5) in the "WSC" SLEEVE (two in each side and one in
the top center).
B. Determine if the sleeve has a downward slope, to the outside, of 1/2 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 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 4. With the help of an assistant, remove the chassis from the shipping carton. Remove the cardboard which is placed
against the hairpins and is taped to the condenser shroud (see Figure 10). Be careful not to allow anything to im-
pact against the hairpins as this may result in damage to them. IMPORTANT: Before installing the unit in the wall
sleeve, remove the two yellow shipping blocks. One shipping block is fixed directly below the control panel on the
front, left side of the unit. A second shipping block is located directly below the left side of the control panel. (see
Figure 11). 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 4-3/4 inches from
the front (side) edge of sleeve.

STEP 5. CHASSIS SEAL GASKET INSTALLATION: After installing the shell, slide the chassis into the shell stopping ap-
proximately 3" from full insertion. Stuff the chassis seal gasket one inch deep between the chassis and the shell (see
Figure 12). 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 amplified.
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 12. 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.
Attach the frame to the chassis by installing four (4) 8A-5/8" screws through the slots
in the frame and into the holes in the chassis

Alternate drain kits
"DK" (Drain Kit)
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.
Condensate removal ("WS","WE" & "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 1. Find the drain plate on the rear of the basepan and remove it. (See Figure 13).
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.
If the chassis must be removed from the sleeve for service, remove the clamped drain hose before sliding the chassis out of
the sleeve.

Instrucciones de Instalacion y Funcionamiento
Para los modelos WallMaster®"WS," "WE" y "WY"
BIENVENIDO: A muchos años de comodidad y economia con su nueva unidad de aire acondicionado para habitació de Friedrich.
Su nueva unidad de aire acondicionado para habitación Friedrich ha sido diseriada y fabricada cuidadosamente para dane muchos
años de operación eficiente, confiable y económica, manteniendo su habitación en niveles cómodos de temperatura y humedad. Se han
puesto muchas caracteristicas adicionales en su aire unidad de acondicionado para habitación Friedrich con el fin de gerantizarle un
funcionamiento silencioso, una mayor irculación de aire frio y seco, una seleoción más flexible de controles de funciones y una mayor
economia en toda la operación.
Hay muchas cosas que usted puede hacer en su casa y airededor de ella para contribuir a economizarie dinero y aun a incrementar la
eficiencia y durabilidad de su unidad Friedrich. A continuación detallamos algunos elemplos:
1. Como graduar el termostato: Cuando usted enciende inicialmente su aire acondicionado, seleccione la máxima velocidad del
ventilador y gradúe el termostato en la posición maxima para enfriar la habitación. Cuando se ha obtenido la temperatum deseada,
cambie el termostato a "warmer" (mas caliente) hasta que el compresor se apague. El termostato hara qua el compresor se prenda
y apague, segun sea neoesario para mantaner esa temparatura. Usted puede graduar la velocidad del ventilador para la mejor
circulación de aire.
2. No obstaculice el flujo de aire hacia y dasde la unidad asegúrese de qua las rejillas de ventilación están dirigidas para dar una
distribución adacuada do aire a toda la habitación. Advertencia: Si se obstruye el aire hacia la unidad y este regresa a ella, puede
ocasionar que la unidad se prenda y apague con excesiva rapidez, 10 cual pueda causarle daño.
3. En la mayoria de las área del país, un aislamiento adecuado, en las paredes, cielo rasos y debajo de los pisos, puede economizarle
hasta un 50% del costo do enfriamiento.
4. Unos rellenos rellenos y el no tener corrientes de aire alrededor de puertas, ventanas, conexiones eléctricas y de tuberías, pueden
significar un 30% de economía en el costo de sus sistemas de enfriamiento y calefación. Asagúrese de que todos los rellenos
alrededor de ellos estén bien hechos.
5. Instale cinta aislante para el clima (preferiblemente metálica) alrededor de sus puertas y vantanas exteriores.
6. ¿Tiene una chimenea? Asegúrese de que la compuerta esté cerrada mientras el aire acondicionado esté funcionando.
7. Elija colores claros cuando tenga qua cambiarle el techo o pintar su casa. Ellos refractan el calor en vaz de absorbarlo.
8. Procure crear sombra para sus parades extariores (espacialmonte las del occidente) para evitar a sol directo; aún más importante,
mantenga su unidad a la sombra. Los árboles y los arbustos proporcionan sombra natural, pero asegúrese de qua ellos no bloquean
el aire alrededor de la unidad. También evita áreas en donde haya mucho polvo o polon, los cuales filtrarán a la unidad.
Si no tiene sombra natural, un todo de lona o una marquesina son la mejor solución para dar sombra a la unidad y las
ventanas.
9. Dentro de la casa, use persianas, biombos o cortinas on las vantanas quo están oxpuestas al sol. Esto disminuirá sus necesidades
de enfriamiento. (Las cortinas forradas o con aislamiento también ayudan a disminuir el costo de calentamiento de la vivienda
en invierno).
10. Asegúrese de que su ático este ventilado adecuadamente. Además, considere instalar una turbina o un ventilador para ayudar
a sacar el aira caliente.
11. Mantenga su unidad de aire acondicionado Friedrich limpia. Use una aspiradora para las partes accesibles pero tenga cuidado
do no dañarlas. Limpie el filtro permanente al menos dos veces al mes.
12. Gradúe el termostato en temperatures más altas (menos frías). Puede economizar un 5% de uso de energía por cada grado en
que usted lo tanga por encima de 72 grados Farenheit (22°C).
Estas son nuestras sugerencias más importantes para economizar sus gastos de aire acondicionado. Algunos de ellos quizás no sean
aplicables en su casa o an su área. Chequée con su compañia de servicios para información más especializada para su caso.

Para arrancar la unidad
Si su aire acondicionado se ha instalado y se ha conectado
en un receptáculo apropiado, está listo para comenzar a
funcionar. La primera ves que se enciende la unidad, el
compresor esperará tres minutos antes de activarse. Lea la
sección titulada Automatic Component Protection (Protección
Automática de los Componentes) en la página 20.
1Toque el botón ON/OFF (encendido/apagado) una
vez. La unidad automáticamente estará en el modo
de COOL (enfriamiento) con una temperatura de 75°F
(24°C) y la velocidad del ventilador en F1, (donde se
coloca para dormir).
Para escoger el modo de funcionamiento
Cuando usted enciende la unidad, automáticamente estará
en modo de COOL (enfriamiento) (luz encendida) y el
ventilador prendido.
2Oprima del botón marcado MODE una vez, para acti-
var la función MoneySaver®(la luz se enciende).
La función MoneySaver®hace que el ventilador se
prenda y apague en ciclos con el compresor para que
el ventilador no funcione todo el tiempo. Esto ahorra
energía y seca la humedad. Si usted prefiere puede
hacer que el ventilador funcione permanentemente
para que haya mayor movimiento de aire. Para re-
gresar a la fución de ventilación constante, oprima
el botón MODE, dos veces más.

El Smart Fan (ventilador) graduará automáticamente la
velocidad para mantener el nivel de comodidad que usted
desee. Por ejemplo, si la puertas exteriores de su casa están
abiertas durante largos períodos, o más personas entran a
un cuarto, el Smart Fan (ventilador) puede ajustarse a una
velocidad más alta para compensar el aumento en la carga
de calor. Esto evita que usted tenga que cambiar la velocidad
del ventilador o la temperatura que ha seleccionado.

NOTA: Si se desconecta la unidad o se interrumpe el
surtido de corriente eléctrica, se debe ajustar la HORA
nuevamente, o la función TIMER ON/OFF no operará
cuando se espera.
Protección automática de los componentes
Su unidad viene con una protección automática de los
componentes.
Para proteger el compresor de la unidad, se ha programado un
tiempo de descanso de tres minutos si usted apaga la unidad
o si se corta la energía. El ventilador no se afectará.
Cuando usted va de COOL (frío) a FAN ONLY (ventilación
sin enfriamiento) e lo vuelve a cambiar a COOL (frío), se
ha programado una demora de tres minutos antes de que el
compresor se vuelva a prender. Esto sirve para protegerlo
