SECURE OWNER’S APPROVAL
When the system is functioning properly, secure the
owner’s approval. Show him the location of all discon-
nect switches and the thermostat. Teach him how to
start and stop the unit, how to adjust temperature set-
tings within the limitations of the system, how the
defrost cycle is controlled and how the anti-cycle timer
operates.
MAINTENANCE
CLEANING
Do not allow dirt to accumulate on the outdoor coil.
Clean the coil with a brush or vacuum cleaner as often
as necessary to assure good system performance and
efficient operation. If the coil is extremely dirty, it may
be necessary to use an industrial grade detergent and
a hose to clean the fin surface.
LUBRICATION
The outdoor fan motors are equipped with factory lubri-
cated and sealed ball bearings. They do not require
any maintenance.
REPLACEMENT PARTS
Contact your local UPG Distribution Center for replace-
ment compressors, fan motors, controls, etc.
NOTICE TO OWNER
If a lockout occurs, check the indoor filters and the out-
door coil before calling a serviceman. If the filters are
dirty, clean or replace them. If there is an accumulation
of snow, leaves or debris blocking the outdoor air coil,
remove the blockage. Reset the thermostat and wait 5
minutes. If the unit doesn’t start, call a serviceman.
