MAINTENANCE / SERVICE
DISCONNECT AND LOCK OUT
POWER WHEN SERVICING UNIT.
FAILURE TO DO SO MAY RESULT IN
PERSONAL IN-JURY OR DEATH
DUE TO ELECTRICAL SHOCK.
Exercise care when working around
the sharp metal edges of door panels
or door frames, etc. These edges can
cause injury.
EVAPORATOR COIL
Inspect the evaporator coil at filter change intervals.
Dirty or clogged evaporator coils causes low suction
pressure and lost capacity. If the coils appear dirty,
they should be cleaned using a mild detergent or a
commercial coil cleaning agent.
REFRIGERANT CIRCUIT(S)-
The Air Conditioning section of this
equipment is charged with R-410A; a high
pressure refrigerant. Only qualified
technicians, using appropriately press-
ure
rated test instruments, should
perform troubleshooting or service on
this equipment.
With the unit operating, check and record the
compressor discharge and suction pressures. The
compressor running current should also be recorded.
A maintenance log of these readings can indicate if
the unit is operating within its normal limits. Abnormal
readings should be investigated, and the Cause
corrected.
BLOWER -
Inspect the evaporator blower at each regular service
interval. Clean blower wheel as needed. Bearings are
permanently sealed ball type, and do not require
lubrication. Check bearings for any signs of wear
(movement between inner and outer races). Ensure
bearing locking collars are secure to the shaft, and
that collar locking screw is properly set. Check that
the blower wheel is tight on the shaft, and that the hub
set screws
are properly torqued.
DRIVE BELT -
Examine belt periodically for wear. Glazed areas on
the drive surfaces indicate overheating due to belt
slippage. Ideal tension is the lowest tension at which
the belt will not slip under peak load conditions. Over-
tensioning shortens belt and bearing life (see section
‘Blower Speed Adjustment’).
The tension on the belt should be adjusted for a
deflection of 1/64 of an inch per inch of belt span, with
the appropriate force applied at the midpoint of the
span (see section ‘Blower Speed Adjustment’).
Tension “New” belts at the maximum value indicated.
Used belts should be maintained at the minimum
value.
FILTERS -
Inspect filters monthly and replace as necessary. Use
UL Class 2 rated filters. Factory supplied filters are
medium efficiency, extended surface pleated type.
Replacements should be of the same type, to
maintain optimum airflow performance. Filter sizes are
as follows:
