 7.2 Care and cleaning
FRONT PANEL AND CARE
- Turn unit off and disconnect power supply. To clean, use water and a mild detergent. DO NOT use
bleach and abrasive. 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 and soot, coil should be
professionally cleaned. Clean inside and outside of outdoor coils regularly.
NOTE: Never use a high-pressure spray on coil.
AIR FILTERS
IMPORTANT:TURN UNIT OFF BEFORE CLEANING.
- The most important thing you can do to maintain unit efficiency is to clean the filters at least every 30
days (or sooner depending on application). Clogged filters reduce cooling, heating and airflow.
- Keeping filters clean will:
Decrease cost of operation.
Save energy.
CAUTION: UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation. Airflow
restriction may cause damage to the unit.

coil and reduce cooling, heating, airflow and efficiency of unit.
Airflow restriction may cause damage to unit.
