Installation Instructions
READ THIS FIRST! Electrical Requirements
WARNING
Electrical Shock Hazard
Make sure your electrical receptacle has the
same conguration as your air conditioner’s
plug. If different, consult a Licensed Electrician.
Do not use plug adapters.
Do not use an extension cord.
Do not remove ground prong.
Always plug into a grounded 3 prong outlet.
Failure to follow these instructions can result
in death, re, or electrical shock.
IMPORTANT: Before you begin the actual installation of your air
conditioner, check your local electrical codes and the information below.
Your air conditioner must be connected to a power source with the same
alternating current (A.C.) voltage and amperage as marked on the name
plate located on the chassis. Only A.C. can be used. Direct Current (D.C.)
cannot be used.
CIRCUIT PROTECTION – Use on single outlet circuit only. An overloaded
circuit will invariably cause malfunction or failure of an air conditioner;
therefore, it is necessary that the electrical protection is adequate. Due
to momentary high current demand when the air conditioner starts, use a
“TIME DELAY” fuse or a HACR type circuit breaker. Consult your dealer or
power company if in doubt.
Refer to the electrical name plate located on the air conditioner chassis
(see Page 2) to determine the correct fuse or circuit breaker amperage for
your model (see Table 1 on Page 5 for electrical receptacle types).
The power cord has a plug with a grounding prong and a matching
receptacle is required.
WARNING
MOVING PARTS HAZARDS
• Do not operate unit out of sleeve or
with front grille removed.
• Do not place hands in blower or fan
blade areas.
Failure to do so can result in serious injury.
CAUTION
Excessive Weight Hazard

Installation Instructions for WSE Sleeve continued
Installation Requirements
STEP 1. The WSE sleeve should be positioned so that the drain
extension extends a minimum of 9/16″ beyond the outside wall
(see Figure 48).
STEP 2. The WSE sleeve must extend a minimum of 7/8″ beyond the
inside wall.
STEP 3. The WSE sleeve must be installed level side to side.
STEP 4. The WSE 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 49, a
properly installed unit provides a 3/8″ slope to the outside of the
building.
NOTICE
Sleeve projections and leveling precautions must be
observed to prevent the entry of water into the room.
Figure 49
Sleeve Requirements
STEP 1. After unpacking the WSE sleeve from the carton, remove the
indoor weather panel. Place the WSE 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 50). Shim at the
top of the sleeve, midway between the sides. Drive one #12A
x 2″ screw in the top of 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 3/8″ downward slope is maintained.
NOTE: If necessary, apply shims below the chassis and inside
the sleeve front unit rest, to ensure a 3/8″ downward slope front
to back.
STEP 3. Caulk the perimeter of the entire opening on the inside and the
outside between the sleeve and the wall.
STEP 4. The indoor weather 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.
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 indoor weather panel.

DRAIN
HOSE
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 WET and WHT models to prevent freezing. (NOTE: In the cooling
mode of the WCT, WET and WHT models, condensate overow is
possible in very humid climates). For these particular instances, an
optional drain kit (Accessory #DK) is available for water removal.
IDK (Drain Kit)
New construction allowing for condensate drain systems built
within the walls can use the Friedrich Interior Drain Kit (Accessory
#IDK). This kit is designed for installation in the bottom of the sleeve
below the condensate bellows valve (heat/ cool models only).

• The outside temperature is below 60 °F
(16 °C).
• The digital control is set to fan cycling mode.
Unit Does Not Cool/ Heat Room
Sufciently, or Cycles On And Off
Too Frequently (continued).
Unit Runs Too Much.
• The air conditioner has insufcient cooling
capacity to match the heat gain of the room.
• The air conditioner has insufcient heating
capacity to match the heat loss of the room.
• This may be due to an excessive heat load
in the room.
• It may also be due to an improperly sized unit.
• This may be normal for higher efciency
(EER) air conditioners.
• You may notice that the discharge air
temperature of your new air conditioner
may not seem as cold as you may be
accustomed to from older units. This
does not; however, indicate a reduction
in the cooling capacity of the unit.
• Do not try to operate your air conditioner in the
cooling mode when the outside temperature is below
60 °F (16 °C). The unit will not cool properly, and the
unit may be damaged.
• Since the fan does not circulate the room air
continuously at this setting, the room air does not
mix as well and hot (or cold) spots may result. Using
the continuous fan setting is recommended to obtain
optimum comfort levels.
• Check the cooling capacity of your unit to ensure it
is properly sized for the room in which it is installed.
Room air conditioners are not designed to cool
multiple rooms.
• Check the heating capacity of your unit. Air conditioners
are sized to meet the cooling load, and heater size
is then selected to meet the heating load. In extreme
northern climates, room air conditioners may not be able
to be used as a primary source of heat.
• If there are heat producing appliances in use in the
room, or if the room is heavily occupied, the unit will
need to run longer to remove the additional heat.
• Be sure to use exhaust vent fans while cooking or
bathing and, if possible, try not to use heat producing
appliances during the hottest part of the day.
• The use of higher efciency components in your new
air conditioner may result in the unit running longer
than you feel it should. This may be more apparent, if
it replaced an older, less efcient, model. The actual
energy usage, however, will be signicantly less
when compared to older models.
• The energy efciency ratio (EER) and cooling
capacity rating (Btu/ h) listed on the unit’s rating
plate are both agency certied.
