OPERATING INSTRUCTIONS

Ensure the following pre-trip inspections are
performed before starting the unit.

WEEKLY PRE-TRIP INSPECTION

The following weekly pre-trip inspection should
be carried out before loading the truck. The
weekly inspection does not replace the regular
maintenance inspections (refer to the section on
the inspection maintenance schedule). However,
it is an important part of the preventative
maintenance programme designed to prevent
operating problems before they occur.

refrigerant lines.
Terminals should be properly tightened

should be 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 millimetres) from the coil surface.
If necessary to use a chemical cleaner or detergent
use a cleaner that does not contain any
hydrofluoric acids and is between 7 and 8 on the
pH scale. Ensure dilution instructions provided by
the detergent supplier are followed. In case of
doubt about the compatibility of the detergent
with the type of materials listed above, always ask
the supplier a written confirmation of the
compatibility. Should a chemical cleaner be
required, it is MANDATORY that all components
are thoroughly rinsed with water even if the
instructions of the cleaner specify that it is a "no
rinse" cleaner. Failure to comply with above
mentioned guidelines will lead to a shortened life
of the equipment to an indeterminable degree.
OPERATING INSTRUCTIONS
The repeated transportation of meat and fish waste
can cause extensive corrosion to the evaporator
coils and evaporator section tubing over time due
to ammonia formation and can reduce the lifespan
of the coils. Appropriate additional measures
should be taken to protect the coils against the
aggressive corrosion that can result from
transportation of such products.
8. Load Compartment. Inspect the interior and
exterior of the truck for any damage. Any damage
to the walls or insulation should be repaired.
Check the defrost drain hoses
