☐ Check the unit’s drain pans and condensate piping
to ensure that there are no blockages.
☐ Check that the condensate overflow switch float
moves freely.
☐ Inspect the evaporator and condenser coils for dirt,
bent fins, etc. If the coils appear dirty, clean them
according to the instructions described in “Coil
Cleaning” later in this section.
☐ Inspect the economizer outside air and return air
damper hinges and pins to ensure that all moving
parts are securely mounted. Keep the blades clean
as necessary.

☐ Manually rotate the condenser fans to ensure free
movement and check motor bearings for wear.
Verify that all of the fan mounting hardware is tight.
☐ Check that all compressor crankcase heaters are
working. Repair any that are not working and wait 8
hours before starting the associated refrigeration
circuit.
☐ Verify that all damper linkages move freely;
lubricate with white grease, if necessary.
☐ Check supply fan motor bearings; repair or replace
the motor as necessary.
☐ With the unit running, check and record the
following:
– ambient temperature
– compressor oil level (each circuit)
– compressor suction and discharge pressures
(each circuit)
– superheat and subcooling (each circuit)
