Structural Maintenance
UNIT AND ENGINE MOUNTING BOLTS
Periodically check and tighten all unit and engine mounting
bolts. Torque the unit mounting bolts to 60 ft-lb
(81.3 N•m). Torque the engine mounting bolts to 50 ft-lb
(68 N•m).
Check Bolts For Tightness
UNIT INSPECTION
Inspect the unit during unit pre-trip inspection and sched-
uled maintenance inspections for loose or broken wires or
hardware, compressor oil leaks, or other physical damage
which might affect unit performance and require repair or
replacement of parts.
EVAPORATOR COIL
Clean the evaporator coil during scheduled maintenance
inspections by blowing compressed air opposite normal air
flow. Inspect the coil and fins for damage and repair if nec-
essary.
CAUTION: Air pressure should not be high enough to
damage coil fins.
CONDENSER COIL
Clean the condenser coil during scheduled maintenance
inspections by blowing compressed air from the back side
of the coil out toward the front of the unit (direction oppo-
site normal air flow). Inspect the coil and fins for damage
and repair if necessary.
FAN LOCATION
When mounting the fan and hub assembly on the fanshaft,
position the assembly in the orifice with 30 to 35 percent of
the blade width to the air discharge side for proper fan per-
formance.
