About the Controls on the Air Conditioner
Additional controls and important information.
Ventilation
The ventilation lever must be in the CLOSE position in order to maintain the best cooling conditions.
When fresh air is necessary in the room, set the ventilation lever to the OPEN position.
The damper is opened and room air is drawn out.
NOTE: Before using the ventilation feature,
make a ventilation kit. First, pull down
part to horizontal line with part .
Air Direction
The direction of air can be controlled wherever you
want to cool by adjusting the horizontal louver and
the vertical louver.
• HORIZONTAL AIR-DIRECTION CONTROL
Control the horizontal air direction by air swing
system.
• VERTICAL AIR-DIRECTION CONTROL
The vertical air direction is adjusted by rotating the
horizontal louver.
How to Secure the Drain Pipe
In humid weather, excess water may cause the BASE
PAN to overflow. To drain the water, remove the DRAIN
CAP and secure the DRAIN PIPE to the rear hole of the
BASE PAN.

About the Controls on the Air Conditioner
Air Filter Cleaning
The air filter behind the front grille should be checked and cleaned at least once every 2
weeks or more often if necessary.
The grille is designed to clean the filter both upward and downward.
TO REMOVE:
1. Open the inlet grille upward by pulling out the bottom of the inlet grille or downward by
pulling out the top of the inlet grille.
2. Using the tab, pull up slightly on the filter to release it and pull it down or up.
3. Clean the filter with warm, soapy water below 40°C (104°F).
4. Rinse and gently shake the water from the filter and let it dry before replacing it.
CAUTION: DO NOT operate the air conditioner without a filter because dirt and lint will
clog it and reduce performance.
Care and Maintenance
TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.
1. Remove the cover from the back of the remote
controller.
2. Insert two batteries.
•Be sure that the (+) and (-) directions are correct.
•Be sure that both batteries are new.
3. Re-attach the cover.
•Do not use rechargeable
batteries. Such batteries
differ from standard dry
cells in shape, dimensions,
and performance.
•Remove the batteries from
the remote controller if the
air conditioner is not going
to be used for an extended
length of time.

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 11" 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.
4. Install the unit a little slanted so the back is slightly lower than the front(about 1/2").
This will force condensed water to flow to the outside.
5. Install the unit with the bottom about 30"~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 22" to 36".
The top and bottom window sash must open
sufficiently to allow a clear vertical opening of
15" from the bottom of the upper sash to the
window stool.

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.

Electrical Safety
Features and Installation
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. 16) 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. 17). 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.

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.
■ TEMP Control set too
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 conditioner's vent to the closed position.
•See Air Conditioner Freezing Up below.
•Set the mode control at High Fan or High Cool with
the high temperature.

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 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.
