05
Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
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.
For Your Safety
Prevent Accidents
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 in
stalled 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.
WARNING
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 mechanical damage within the air
conditioner.
Do not use an extension cord or an adapter plug.
Electrical Information
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.

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.
Removing AC From Window
Turn AC o, 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
unit from window. Store parts with air conditioner.
High Pitched Chatter
High eciency 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 Eciency 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.

How to clean & change your filter.
Cleaning & maintenance
Check the air filter once a month
to see if cleaning is necessary.
CAUTION: Clean your air conditioner occasionally to
keep it looking new. Be sure to unplug the unit before
cleaning to prevent chock or fire hazards.
CAUTION: If you plan to store the air conditioner during the winter,
remove it carefully from the window according to the installation

detergent and warm water. Rinse filter

filter. Be sure the filter is thoroughly dry before
replacing. Instead of washing, you may vacuum
the filter clean.

clean the air filter. Never attempt to operate
the unit without the air filter.
Cabinet Cleaning
• 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 cleaners, wax or polish
on the cabinet front.
• Be sure to wring excess water from the
cloth before wiping around the controls.
