CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment dam-
age or improper operation. Do not operate unit without fil-
ters in place. If a filter becomes torn or damaged, it should
be replaced immediately. Operating without filters in place
or with damaged filter will allow dirt and dust to reach in-
door coil and reduce cooling, heating, airflow and efficiency
of unit. Airflow restriction may cause damage to unit.
The most important thing you can do to maintain unit
e󰀩ciency is to clean the lters once every two weeks as re-
quired. Clogged lters reduce cooling, heating, and airow.
Keeping lters clean will:
• Decrease cost of operation.
• Save energy.
• Prevent clogged indoor coil.
• Reduce risk of premature component failure.
To Clean Air Filters:
• Vacuum o󰀨 heavy soil.
• Run water through lter.
• Dry thoroughly before replacing.
