HOW TO SECURE THE DRAIN PIPE
AIR FILTER CLEANING
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.
The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped particles in
the filter will build up and block the airflow. This reduces the cooling capacity and also causes an
accumulation of frost on the cooling coils.
1. Open the inlet grille upward by pulling out the bottom of the inlet grille.
2. Remove the air filter from the front grille assembly by pulling the air filter up slightly.
3. Wash the filter using lukewarm water below 40°C (104°F).
4. Gently shake the excess water from the filter completely. Replace the filter.

INSTALLATION INSTRUCTIONS
SELECT THE BEST LOCATION
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 12" 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.
WINDOW REQUIREMENTS
1. This unit is designed for installation in
standard double hung windows with actual
opening widths from 27" to 39".
The top and bottom window sash must open
sufficiently to allow a clear vertical opening of
16" from the bottom of the upper sash to the
window stool.
2. Install the unit a little slanted so the back is
slightly lower than the front(about 1/2").
This will help force condensed water to flow to
the outside.
3. Install the unit from the bottom about 30"~60"
above the floor level.

For Your Safety
Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any
other appliance. Read caution label for flamma-
bility and other warnings.
Prevent Accidents
To reduce the risk of fire, electrical shock, or
injury to persons when using your air conditioner,
follow basic precautions, including the following:
• Be sure the electrical service is adequate for
the model you have chosen. This information
can be found on the serial plate, which is
located either behind the louvers or on the left
side of the cabinet.
• If the air conditioner is to be installed in a win-
dow, you will probably want to clean both sides
of the glass first. If the window is a triple-track
type with a screen panel included, remove the
screen completely before installation.
• Be sure the air conditioner has been securely
and correctly installed according to the separate
installation instructions provided with this
manual. Save this manual and the installation
instructions for possible future use in removing
or reinstalling this unit.
• When handling the air conditioner, be careful to
avoid cuts from sharp metal fins or front and
rear coils.
Electrical Information
The complete electrical rating of your new room
air conditioner is stated on the quality label.
Refer to the rating when checking the electrical
requirements.
• Be sure the air conditioner is properly ground-
ed. To minimize shock and fire hazards, proper
grounding is important. The power cord is
equipped with a three-prong grounding plug for
protection against shock hazards.
• Your air conditioner must be used in a properly
grounded wall receptacle. If the wall receptacle
you intend to use is not adequately grounded
or protected by a time delay fuse or circuit
breaker, have a qualified electrician install the
proper receptacle.
• Do not run air conditioner with outside protec-
tive cover in place. This could result in mechan-
incal damage with in the air conditioner.
• Do not use an extension cord or an adapter
plug.
