INSTALLATION
Features and Installation
1. To prevent vibration and noise, make sure
the unit is installed securely and firmly
2. Install the unit where the sunlight does not
shine directly on the unit.
3. The outside of the cabinet must extend
outward for at least 28cm (11) and there
should be no obstacles, such as a fence or
wall, within 50.8cm (20) from the back of
the cabinet because it will prevent heat
radiation of the condenser.
Restriction of outside air will greatly reduce
the cooling efficiency of the air conditioner.
CAUTION: All side louvers of the cabinet must remain exposed to the outside of the
structure.
4. Install the unit a little slanted so the back is slightly lower than the front 
(about 12.7mm (
1/2)).
This will force condensed water to flow to the outside.
5. Install the unit with the bottom about 76.2cm (30)~152.4cm (60) above the floor level.
Window Requirements
NOTE: All supporting parts should be secured to firm wood, masonry, or metal.
This unit is designed for installation in
standard double hung windows with actual
opening widths from 55.88cm (22) to
91.44cm (36).
The top and bottom window sash must open
sufficiently to allow a clear vertical opening of
38cm (15) from the bottom of the upper sash
to the window stool.

Electrical Safety (Applies to USA and Puerto Rico)
Features and Installation
IMPORTANT
(PLEASE READ CAREFULLY)
FOR THE USERS PERSONAL SAFETY, THIS
APPLIANCE MUST BE PROPERLY GROUNDED
The power cord of this appliance is equipped with a
three-prong (grounding) plug. Use this with a
standard three-slot (grounding) wall power outlet
(Fig. 12) to minimize the hazard of electric shock.
The customer should have the wall receptacle and
circuit checked by a qualified electrician to make
sure the receptacle is properly grounded.
DO NOT CUT OR REMOVE THE THIRD
(GROUND) PRONG FROM THE POWER
PLUG.
A. SITUATIONS WHERE THE APPLIANCE
WILL BE DISCONNECTED ONLY 
OCCASIONALLY:
Because of potential safety hazards, we strongly
discourage the use of an adapter plug. However, if
you wish to use an adapter, a TEMPORARY
CONNECTION may be made. Use UL-listed
adapter, available from most local hardware stores
(Fig. 13). The large slot in the adapter must be
aligned with the large slot in the receptacle to
assure a proper polarity connection.
CAUTION: Attaching the adapter ground terminal to
the wall receptacle cover screw does not ground the
appliance unless the cover screw is metal, and not
insulated, and the wall receptacle is grounded
through the house wiring. 
The customer should have the circuit checked by a
qualified electrician to make sure the 
receptacle is properly grounded.
Disconnect the power cord from the adapter, using
one hand on each. Otherwise, the adapter ground
terminal might break. DO NOT USE the appliance
with a broken adapter plug.
B. SITUATIONS WHERE THE APPLIANCE
WILL BE DISCONNECTED OFTEN.
Do not use an adapter plug in these situations.
Unplugging the power cord frequently can lead to
an eventual breakage of the ground terminal. The
wall power outlet should be replaced by a three-slot
(grounding) outlet instead.
USE OF EXTENSION CORDS
Because of potential safety hazards, we strongly
discourage the use of an extension cord. However,
if you wish to use an extension cord, use a CSA
certified/UL-listed 3-wire (grounding) extension
cord, rated 15A, 125V. Fig. 12

Models: CW-XC64HU, CW-XC64HK, CW-XC84GU, CW-XC84HK, CW-XC84HU
Normal Operation
• You may hear a pinging noise caused by water being picked up and thrown against the condenser
on rainy days or when the humidity is high. This design feature helps remove moisture and improve
efficiency.
• You may hear the relay click when the compressor cycles on and off.
• Water will collect in the base pan during high humidity or on rainy days. The water may overflow
and drip from the outdoor side of the unit.
• The fan may run even when the compressor does not.
Abnormal Operation
Problem Possible Causes What To Do
 The air conditioner is
unplugged.
 The fuse is blown/circuit
breaker is tripped.
 Power failure.
 Airflow is restricted.
 TEMP Control set to a
higher number.
 The air filter is dirty.
 The room may have been
hot.
 Cold air is escaping.
 Cooling coils have iced up.
 Ice blocks the air flow and
stops the air conditioner
from cooling the room.• Make sure the air conditioner plug is pushed
completely into the outlet.
• Check the house fuse/circuit breaker box and
replace the fuse or reset the breaker.
• When power is restored, wait 3 minutes to restart the
air conditioner to prevent tripping of the compressor
overload.
• Make sure there are no curtains, blinds, or furniture
blocking the front of the air conditioner.
• Set the TEMP Control to a lower number.
• Clean the filter at least every 2 weeks.
See the operating instructions section.
• When the air conditioner is first turned on 
you need to allow time for the room to cool down.
• Check for open furnace floor registers 
and cold air returns.
• Set the air conditioners vent to the closed position.
• See Air Conditioner Freezing Up below.
• Set the mode control to High Fanat a high
temperature.
