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.
2. Normal Sounds
High Pitched Chatter
High e ciency compressors may have a high pitched chatter during the cooling cy-
cle.
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 evapo-
rator 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 E
ciency of your unit.
Note:
Don’t try to drill any holes on the base pan to eliminate the normal sounds, other-
wise it will void the warranty.
