NOTE!
Before using the air conditioner secure
the front grille with two screws enclosed
with the owner’s manual.
1. Open the inlet grille downward and
remove the air filter.
2. Fasten the front grille with screws.
3. Reinstall the air filter.

How to Install the Unit
Window Requirements
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 14" and there should be no obstacles, such as a
fence or wall, within 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.xz
4. Install the unit a little slanted so the back is slightly lower than the front(about 1/4").
This will force condensed water to flow to the outside.
5. Install the unit with the bottom about 30"~60" above the floor level.
1. These instructions are for a horizontal sliding or a
casement window.
2. The electrical outlet must be within reach of the
power cord.
For installation in a casement window, the window
frame assembly and the side of the building must be
adequate to support the weight of the air conditioner.

1. Loosely attach the Support Bracket to the bottom of Bracket
using Bolts, Washer, and Nuts. Attach the Leveling bolt and
nut. (Fig. 1)
2. Remove protective backing from Window Track Seal and apply
seal to window track. (Fig.2)
3. Measure and lightly mark a line 8-1/4 inches from window

Put the Support Bracket against the outside wall and tighten the
Bolts on top of the Bracket. Adjust the Leveling Bolt so that the
air conditioner will be installed with a very slight tilt (about 1/4")
downward toward the outside for proper drainage.
Tighten the nut. (Fig. 3)
NOTE: DO NOT drill a hole in the bottom of the base pan. The air
conditioner is designed to operate with the bottom of the
base pan approximately half-full of water.

Electrical Data
1. Installation procedure is the same as that described in steps 1 through 11 and step 13 of the Horizontal Sliding
Window installation.
2. If the window opening is wider than 15-3/4 inches you will need to install a filler panel. Make this panel from
3/4 inch thick wood and run it the full length of the window.
Attach it securely to the window frame and paint it to protect it from the weather.
3. Since styles and sizes of casement windows vary widely, it is advisable to have the air conditioner installed by
someone skilled in this type of installation.
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.
Do not under any
circumstances cut
or remove the
grounding prong
from the plug.

IMPORTANT
(PLEASE READ CAREFULLY)
FOR THE USER'S 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. 10) 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 store(Fig. 11). 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.

Before you call for service...
Common
Issues
• 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 thermostat 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.
Troubleshooting Tips
Save time and money! Review the chart below first and you may not need to call for service.
Problem Possible Causes What To Do
■ The air conditioner is unplugged.
■ The fuse is blown/circuit breaker is
tripped.
■ Power failure.
■ Airflow is restricted.
■ The TEMP Control may not be set
high enough.
■ 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.
•
If power failure occurs, turn the mode control to Off.
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.
• Turn the knob to a higher number.
The highest setting provides maximum cooling.
• Clean the filter at least every 2 weeks.
See the care and maintenance 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 conditioner's vent to the closed
position.
• See Air Conditioner Freezing Up below.
• Set the mode control at High Cool with the high
temperature mark 1 or 2.
