Unit and Engine Mounting Bolts
Check and tighten all unit and engine mounting
bolts during scheduled maintenance inspections.
Torque the unit mounting bolts to 60 ft-lb
(81 N•m). Torque the engine mounting bolts to
150 ft-lb (203 N•m).
Unit Inspection
Inspect the unit during pretrip inspection and
scheduled 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.
Condenser, Evaporator, and
Radiator Coils
Clean the coils during scheduled maintenance
inspections. Remove any debris (e.g., leaves or
plastic wrap) that reduces the air flow. Clean dirty
coils with compressed air or a pressure washer. Be
careful not to bend the fins when cleaning a coil.
If possible, blow the air or water through the coil
in the direction opposite the normal airflow.
Repair bent fins and any other noticeable damage.
Defrost Drains
Clean the defrost drains during scheduled
maintenance inspections to be sure the lines
remain open.
Unit Installation
All nuts that hold the unit to the trailer are
accessible using an impact wrench with a 10 in.
extension, ball-type swivel and a deep-well
socket.
NOTE: The nuts for mounting the unit should
be elastic stop nuts (Nylock type).
