Routine maintenance should include the following:
Regular Cleaning
CAUTION:
DO NOT touch any of the internal electrical
components while cleaning the unit.
• The area around the unit and the vicinity of any other
appliances must be kept clear and free of combustible
materials, gasoline, and other flammable vapors and
liquids. Do not store or use flammable items such as
gasoline, paint, varnish, or strippers in the vicinity of
the unit.
• Keep the outdoor unit clean. Hose off periodically and
keep unit fins clear of leaves and grass clippings. Be
careful not to damage the aluminum fins. Clean
the outdoor coil and fins as necessary using a mild
detergent and water. Rinse thoroughly with water.
• Keep the outdoor unit clear of obstructions. DO NOT
obstruct airflow with tall plants or shrubs. Check for and
remove any obstructions such as twigs, sticks, etc.
• Inspect the condensate drain and outdoor coil at the
beginning of each cooling season. Remove any debris.
Air Filters
WARNING:
Never operate the unit without a filter in the
return air system. Dust and lint in the return
air can build up on the internal components,
resulting in loss of efficiency, equipment
damage, and possible fire risk.
• Inspect and clean or replace air filters at the beginning
of each heating and cooling season, or more frequently
if required. A clogged filter could cause airflow related
problems and reduce the overall efficiency of your unit.
Always replace disposable filter(s) installed in your
system only with the same size dimensional filters
that are being replaced.
• Never operate the appliance without a filter installed in
the return air duct. Inspect filters frequently and replace
when necessary with filter of same dimensional size.
