CARE AND CLEANING
FRONT PANEL AND CASE
Turn unit off and disconnect power supply.
To clean, use water and a mild detergent. DO NOT use bleach or abrasives. Some commercial cleaners may damage the plastic parts.
OUTDOOR COIL
Coil on outdoor side of unit should be checked regularly. Unit will need to be removed to inspect dirt build-up that will occur on
the inside of the coil. If clogged with dirt or soot, coil should be professionally cleaned.
NOTE: Never use a high-pressure spray on coil.
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Airow restriction may cause damage to the unit.

IMPORTANT: TURN UNIT OFF BEFORE CLEANING
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Do not operate unit without lters in place. If a lter becomes torn or damaged, it should be replaced immediately.
Operating without lters in place or with damaged lters will allow dirt and dust to reach indoor coil and reduce
cooling, heating, airow and efciency of unit. Airow restriction may cause damage to unit.
!
Themost important thing you can do to maintain unit efciency is to clean the lters at least every 30 days (or sooner depending
on application). Clogged lters reduce cooling, heating and airow.
Keeping lters clean will:
• Decrease cost of operation.
• Save energy.
• Prevent clogging the indoor coil.
• Reduce risk of premature component failure.
To Clean Air Filters:
• Vacuum off heavy soil.
• Run water through lters.
• Air dry thoroughly before replacing.
