FAN MOTORS:
Lubricate fan motors annually. All
ClimateMaster Rooftop Units are fully lubricated at the
factory. Do not oil during installation.
Conduct Amperage checks annually. Amp draw should
not exceed normal full load or rated load amps by
more than 10 percent of the values noted on the unit
nameplate. Maintain a log of Amperage values to detect
deterioration prior to component failure.
UNIT INSPECTION:
Visually inspect the unit annually. Pay
special attention to hose assemblies. Repair any leaks and
replace deteriorated hoses immediately.
COMPRESSOR:
Conduct an Amperage check on the
compressor(s) annually. Amp draw should not exceed
normal full load or rated load amps by more than 10
percent of the values noted on the unit nameplate.
Maintain a log of Amperage values to detect
deterioration prior to component failure.
Preventive Maintenance
MAINTENANCE PROCEDURES -
Perform the
maintenance procedures outlined below periodically
as indicated.

WARNING!
To prevent injury or death due to electrical shock
or contact with moving parts, open unit disconnect switch
before servicing unit.
�
CAUTION!
�
CAUTION!
To avoid fouled machinery and extensive unit
cleanup, do not operate units without filters in place. Do
not use equipment as a temporary heat source during
construction.

WARNING!
�
WARNING!
When replacing the compressor contactor or
lockout controls, use only ClimateMaster replacement parts.
Substitution of other components may result in an inoperative
safety circuit and may cause a hazardous condition.
FILTERS:
Inspect filters. Establish a regular maintenance
schedule. Clean filter and maintenance frequently
depending upon need. To remove the filter from a
Rooftop Unit, slide the filter out of its frame located in
the return air opening. When reinstalling the filter, use
the slide-in rails of the filter frame to guide the filter into
the proper position. Verify that the airflow arrow found
on the top of each filter points toward the unit. Always
replace filters with the same size and quantity of filters as
removed from the unit.
CONDENSATE PANS:
Check condensate drain pans
for algae growth every three months. If algae growth is
apparent, consult a water treatment specialist for proper
chemical treatment. The application of an algaecide every
three months will typically eliminate algae problems in
most locations.
AIR COIL:
Inspect the air coil annually for dirt
accumulation. Clean coil as needed using a spray-on
foaming coil cleaner. Rinse with clean water. Brushing
coils should be avoided to avoid damage to coil fins.
