CORD
The complete electical rating of your new room air 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 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. Ensure the receptacle is
accessible after the unit installation.
• Do not run air conditioner without side protective cover in place.This could result in mechani-
cal damage within the air conditioner.
• Do not use an extension cord or an adapter plug.
Avoid fire hazard or electric shock. Do not use an extension
cord or an adapter plug. Do not remove any prongs from
the power cord.
Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
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 on the side of the the cabinet and behind the
grille.
• If the air conditioner is to be installed in a window, you will probably want to clean both sides
of the glass first. If the window is a triple-trackty pew it has creen panel included, remove the
screen completely before installation.
• Be sure the air conditioner has been securely and correctly installed according to the
installation instructions in this manual. Save this manual for possible future use in removing or
installing this unit. When handling the air conditioner, be careful to avoid cuts from sharp
metal fins on front and rear coils.

One more thing
Add wood as shown in Caution illustration on page 16, or remove
storm window before air conditioner is installed. If Storm Window
Frame must remain, be sure the drain holes or slots are not caulked
or painted shut. Accumulated Rain Water or Condensation must be
allowed to drain out.
High Pitched Chatter
High efficiency compressors may have a high pitched chatter during the
cooling cycle.
Sound of Rushing Air
At the front of the unit, you may hear the sound of rushing air being
moved by the fan.
Gurgle/Hiss
“Gurgling or hissing”noise may be heard due to refrigerant passing
through evaporator during normal operation.
Vibration
Unit may vibrate and make noise because of poor wall or window
construction or incorrect installation.
Pinging or Switching
Droplets of water hitting condenser during normal operation may cause
“pinging or swishing” sounds. This noise can be reduce by removing the
water plug at the bottom of unit’s rear as shown below. Removing this
plug will lower the Energy Efficiency of your unit.
Note: Don’t try to drill any holes on the base pan to eliminate the normal
sounds, otherwise it will void the warranty.
If AC is Blocked by Storm Window
Normal Sounds
Additional Notes
Noise when unit is working
When you use the mute mode to start the unit. due to the compressor
being hot. the sound of the compressor may be more prominent. lasting
for about 3 minutes. It is normal.
A“da-da" sound may occur for thirty seconds when the unit is turned on
due to the compressor starting. It is normal.
Turn AC off, and disconnect power
cord. Remove sash seal from between windows, and unscrew safety
sash lock. Remove screws installed through frame and frame- lock.
Keeping a firm grip on air conditioner, raise sash and carefully
remove. Be carefully not to spill any remaining water while lifting

How to clean & change your filter
Cleaning & maintenance
Check the air filter once a month
to see if cleaning is necessary
Cabinet Cleaning
The air filter should be checked at least once a month to see if cleaning is necessary. Trappedparticles in the
filter can build up and cause an accumulation of frost on the cooling coils.
• Push the vent handle to the Vent Closed position (where applicable). Open the front panel.
• Take the filter by the center and pull up and out.
• Wash the filter using l iquid dishwashing
detergent and warm water. Rinse filter thoroughly. Gently shake excess water from the filter. Be sure the filter
is thoroughly dry before replacing. Instead of washing, you may vacuum the filter clean.
Note: Never use hot water over 40°C ( 104°F ) to
clean the air filter. Never attempt to operate
the unit without the air filter.
• 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 dishwash-
ing detergent. Rinse thoroughly and wipe dry.
• Never use harsh cleaners, 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.
CAUTION: 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.
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.
