WARNING:
To prevent electrical shock, personal injury, or
death, disconnect all electrical power to the unit
before performing any maintenance or service.
The unit may have more than one electrical supply.
Proper maintenance is important to achieve optimum
performance from the air conditioner. The ability to properly
perform maintenance on this equipment requires certain
mechanical skills and tools. If you do not possess these
skills, contact your dealer for maintenance. Consult your
local dealer about the availability of maintenance contracts.
Routine maintenance should include the following:
• Inspect and clean or replace air filters at the beginning of
each heating and cooling season, or more frequently if
required.
• Inspect the condensate drains in the unit's basepan and
the outdoor coil at the beginning of each cooling season.
Remove any debris. Clean the outdoor coil and louvers
as necessary using a mild detergent and water. Rinse
thoroughly with water.
• To access the outdoor coil on units equipped with louvered
for panel removal
for panel installation.
• Inspect the electrical connections for tightness at the
beginning of each heating and cooling season. Service
as necessary.
• Do not attempt to add additional oil or grease to motors
unequipped with oil tubes or grease fittings. Most outdoor
unit motors are manufactured with sealed, permanently
lubricated bearings that are designed for the life of the
equipment without maintenance.
• The compressor is hermetically sealed and shipped from
the factory with the proper oil charge for most installations.
Lubricating oil should only be added by trained personnel
and is typically only required for long line-sets or tall riser
applications.
