Usage
Cleaning and maintenance
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.

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 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.
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.

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 at 15A, 125V.

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 (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 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 (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 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
you wish to use an extension cord, use a CSA
certified/UL-listed 3-wire (grounding) extension cord,
rated at 15A, 125V.

Common Problems and Solutions
Common
Issues
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:
Problem Possible Causes What To Do
■The air conditioner is unplugged or
not plugged in completely
■The fuse is blown/circuit breaker is
triggered
■Power failure.
■Air flow is restricted
■The THERMOSTAT may not be
set cool enough
■The air filter is dirty.
■The air conditioner was just
turned on.
■Cold air is escaping.
■Cooling coils are iced up
■The cooling coils are iced over.
•Make sure the plug is completely plugged into
the outlet
•Check the fuse/circuit breaker box and replace
the fuse or reset the breaker
•In the event of a power failure, set the power
control to OFF. When the power is restored,
wait 3 minutes to restart the air conditioner to
prevent the compressor from overloading
•Make sure there are no curtains, blinds,
furniture or other obstacles in front of the air
conditioner
•Turn the knob to a higher setting. The highest
setting provides maximum cooling
•Clean the filter at least every 2 weeks. Refer to
the “Care and Maintenance”section (p.11) of
the manual.
•After the air conditioner is turned on, you need
to give the air conditioner some time to cool the
room.
•Check for open furnace floor resisters and cold
air returns.
•CLOSE the air conditioner vent
•See Ice appears on the air conditioner below
•Ice may block the air flow and obstruct the air
conditioner from properly cooling the room. Set
the fan at MED or HIGH while setting the
thermostat at 1 or 2 until the ice melts.
