NOTE
The power supply cord with this
air conditioner contains a current
detection device designed to reduce
the risk of fire.
Please refer to the section Operation of
Current Device for details.
In the event that the power supply cord
is damaged, it can not be repaired. It
must be replaced with a cord fromthe
manufacturer.
WARNING - For your safety
• Do not store or use gasoline or other
flammable vapors and liquids in the
vicinity of this or any other appliance.
• Avoid fire hazard or electric shock.
Do not use an extension cord or an
adaptor plug. Do not remove any
prongs fromthe power cord.
WARNING - Electrical Information
The complete electrical rating of
your new roomair conditioner is
stated on the serial plate. Refer to the
rating when checking the electrical
requirements.
• Be sure the air conditioner is
properly grounded. 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
connected to 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.
• Ensure the receptacle is accessible
after the unit installation.
• Do not run air conditioner without
outside protective cover in place.
This could result in mechanical
damage within the air conditioner.

To operate on Auto feature:
• When you set the air conditioner to
AUTO mode, it will automatically select
cooling or fan only operation depending
on what temperature you have selected
and the current room temperature.
• The air conditioner will control room
temperature automatically according
to the temperature you’ve set.
• In this mode, the fan speed cannot be
adjusted, as it’s automatically controlled
according to the temperature setting
and room temperature.
To operate on Fan Only:
• Use this function only when cooling is not
desired, such as for room air circulation
or to exhaust stale air (on some models).
(Remember to open the vent during
this function, but keep it closed during
cooling for maximum cooling efficiency.)
You can choose any fan speed you prefer.
• During this function, the display will
show the actual room temperature,
not the set temperature as in the
cooling mode.
• In Fan Only mode, the temperature is
not adjusted.
To operate on Dry mode:
In this mode, the air conditioner will
generally function as a dehumidifier. Since
the conditioned space is a closed or sealed
area, some degree of cooling will occur.

the same time, for 3 seconds.
The Fresh Air Vent allows the air conditioner to:
1. Recirculate inside air – Vent Closed (See Fig. A)
2. Draw fresh air into the room - Vent Open (See Fig. B)
3. Exchange air from the room and draw fresh air into the room - Vent and Exhaust
Open (See Fig. C).

2. PREPARE AIR CONDITIONER
Before installing the unit, the top rail must be assembled on the unit for models with a
capacity of less than 10,000Btu/h.
CAUTION
When handling unit, be careful to
avoid cuts fromsharp metal edges
and aluminumfins on front and rear
coils.
1. PREPARE THE WINDOW
Lower sash must open sufficiently to allow a clear vertical opening (see dimension
H in Table 1). Side louvers and the rear of the AC must have clear air space to allow
enough airflow through the condenser for heat removal. The rear of the unit must be
outdoors, not inside a building or garage.
NOTE
Save carton and these Installation Instructions for future reference. The carton is the
best way to store unit during winter, or when not in use.

Installation
Instructions
1. Place unit on floor, a bench or a table. There is a left and right side accordion panel; be
sure to use the proper panel for each side. When installed, the flange for securing the
panel in place to the window sill will be facing into the room.
A. Hold the side panel in one hand and gently pull back the center to free the open
end. See Fig. 1.
B. Slide the free and “I” section of the panel directly into the cabinet as shown in Fig. 2.
Slide the panel down. Be sure to leave enough space to slip the top and bottom of
the frame into the rails on the cabinet.
C. Once the panel has been installed on the side of the cabinet, make sure it sits
securely inside the frame channel by making slight adjustments. Slide the top and
bottom ends of the frame into the top and bottom rails of the cabinet. Fig. 3.
NOTE
Top rail and side panels at each side are offset to provide the proper pitch to the rear of
5/16” (8mm). This is necessary for proper condensed water management and drainage. If
you are not using the side panels for any reason, this pitch to the rear must be maintained.
NOTE
For safety reasons, all
four (4) screws MUST be
securely fastened.
C: Align the hole in the top rail with those in the top of the unit as shown in Fig. F.
D: Secure the top rail to the unit with the 3/8” (9.5mm) screws as shown in Fig. G.

Check that air conditioner is tilted back
per dimension H (Fig. 5) (tilted about 3°
to 4° downward to the outside). After
proper installation, condensate should
not drain fromthe overflow drain hole
during normal use. Adjust the slope if
otherwise.

Air Filter Cleaning
Cabinet Cleaning
Winter Storage
• Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet and
front may be dusted with an oil-free cloth or washed with a cloth dampened in a solution
of warm water and mild liquid dishwashing detergent. Rinse thoroughly and wipe dry.
• Never use harsh cleansers, wax or polish on the cabinet front.
• Be sure to wring excess water from the cloth before wiping around the controls.
Excess water in or around the controls may cause damage to the air conditioner.
• Plug in air conditioner.
Care and
Cleaning
CAUTION
Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the
unit before cleaning to prevent shock or fire hazards.
NOTE
Never use hot water over 104°F (40°C) to clean the air filter. Never attempt to
operate the unit without the air filter.
If you plan to store the air conditioner during the winter, remove it carefully from the
window according to the installation instructions. Cover it with plastic or return it to
the original carton.
Care and Cleaning
The air filter should be checked at least once a month to see if cleaning is necessary. Trapped
particles in the filter can build up and cause an accumulation of frost on the cooling coils.
• Push the vent handle to the closed position (where applicable). Open the front panel.
• Take the filter by the center and pull up and out.
• Wash the filter using liquid dishwashing detergent and warm water. Rinse filter thoroughly.
• Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing.
• You may also vacuum the filter clean rather than washing.
