Manual Pretrip Inspection
28
NOTE: All truck and trailer units will have a small battery
drain when the unit is off. The battery can be drained even
quicker if there are Aftermarket options or third party devices
connected to the unit which consume battery power.
This will cause the battery to become discharged over time.
Apart from the obvious inconvenience of having to charge
the battery, it is also liable to damage battery cell material
and cause the life of the battery to be shorter than acceptable.
Therefore, to ensure the battery remains in optimum
condition during periods when the unit is not being used,
Thermo King strongly recommends to switch on the unit at
least once each week and run for 30 minutes or longer.
Failure to do so may result in warranty for the battery being
rejected.
Alternatively, Thermo King offer a solar panel option from
aftermarket which would negate the requirement to switch
off the microprocessor switch during long unit idle periods.
For more information, please contact your local Thermo
King dealership.
Belts:
Make sure belts are in good condition and adjusted to
the proper tension. For more information about belt tension,
see the Specifications chapter.
Electrical:
Check the electrical connections to make sure they
are securely fastened. Wires and terminals should be free of
corrosion, cracks, and moisture.
Structural:
Visually inspect the unit for leaks, loose or
broken parts, and other damage.
Coils:
Ensure condenser and evaporator coils are clean and
free of debris.
•
Washing with clean water should be sufficient.
•
The use of cleaning agents or detergents is strongly
discouraged due to the possibility of degradation of the
construction.
•
If using a power washer, the nozzle pressure should not
exceed 600 psi (41 bar). For the best results, spray the coil
perpendicular to the face of the coil. The spray nozzle
should be kept between 1 inch and 3 inches (25 to 75
millimeters) from the coil surface.
