Usage
Cleaning and maintenance
Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp
metal edges.
Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading
to possible electric shock.
When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a
very high speed during operation. There is a possibility of injury if the unit’s power is accidentally
triggered on while cleaning inner parts of the unit.

Service
For repair and maintenance, contact your authorized service dealer.
Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not
expose occupants, pets, or plants to direct airflow for extended periods of time.
Due to the possibility of oxygen deficiency, ventilate the room when using together with stoves or other
heating devices.
Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices,
food, pets, plants, and art objects). Usage in such a manner could harm such property.

Electrical Safety
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 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 WHEN THE APPLIANCE WILL BE
DISCONNECTED 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.
The large slot in the adapter must be aligned with the
large slot in the receptacle to assure a proper polarity
connection.
: 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 WHEN 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
youwishtouseanextensioncord,useaCSA
certified/UL-listed 3-wire (grounding) extension cord,
rated at 15A, 125V.

•Adjusting Horizontal Air Flow Direction
Adjusting the vertical louvers left and right will
change horizontal airflow.
•Adjusting Vertical Air Flow Direction
Adjusting the horizontal vane up and down will
change vertical airflow. The vane can be adjusted
by nudging the vane backward or forward.
Adjusting the Air Flow Direction
For maximum cooling efficiency, CLOSE the vent. This will allow internal air circulation.

Turn the power off and unplug the power plug before cleaning the air conditioner.
Air Filter
The air filter behind the inlet grille should be checked and cleaned at least once every 2 weeks (or as
necessary) to maintain optimal performance of the air conditioner.
How to remove the air filter
The grille may be opened from the top for easy
maintenance after installation.
Open the inlet grille by pulling off the exposed door
on the top of the unit (based on installation).
Pull the tab slightly to release the filter. Pull the filter
in the same direction as the opening.
Clean the filter with warm, soapy water. The water
should be below 40°C (104°F).
Rinse off and gently shake off excess water from the
filter. Let it dry before replaceing it.

How to Attach Drain Pan (Optional)
The air conditioner employs a proper drain method whereby the condensed water (moisture removed from the
air) is drained to the outside.
In very humid weather, (and for reverse cycle models in the reverse mode) excessive condensate water removed
from the air may cause some water to collect. To remove this excess water you can install the drain pan as
detailed below.

How to Install the Unit
To prevent vibration and noise, make sure the unit
is installed securely and firmly.
Install the unit where the sunlight does not shine
directly on the unit.
There should be no obstacles, such as a fence and
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.
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.
Install the unit with the bottom about 30"~60" above the floor level.

allow a clear vertical opening of 19" from the bottom of the
upper sash to the window stool.

Common Issues
ENGLISH
Before calling for service, please review the following list of common problems and solutions.
The air conditioner is operating normally when:
•You hear a pinging noise. This is caused by water being picked up by the condenser on rainy days or in highly
humid conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency.
•You hear the thermostat click. This is caused by the compressor cycle starting and stopping.
•You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid
conditions or on rainy days. This water overflows and drips from the rear of the unit.
•You hear the fan running while the compressor is silent. This is a normal operational feature.
The air conditioner may be operating abnormally when:
Common Problems and Solutions
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 conditioner's vent to the closed
position.
•See Air Conditioner Freezing Up below.
•Set the mode control at High Fan at a high
temperature.
