SAFETY PRECAUTIONS
Fluorocarbon refrigerants tend to displace air and
can cause oxygen depletion which could result in
death by suffocation. Observe caution at all times
when working with or around refrigerants, or air
conditioning systems containing refrigerants,
especially in enclosed or confined areas.
AUTO START
Thermo King truck powered refrigeration units
may start up automatically at any time.
Ensure that the unit is switched off before
inspecting any component part.
ELECTRICAL HAZARD
Ensure that high voltage energy supply is
switched off and disconnect the electric cable
before working on the unit. Units with electrical
power supply present a potential electrical hazard.
WARNING
Electric welding generates high ampere
currents which can damage electrical and
electronic components. To minimise damage,
prior to any welding operation on the vehicle,
the microprocessor controller and unit battery
must be electrically disconnected from
the vehicle. Turn off the microprocessor’s
On/Off switch. Remove the battery negative
cable. Remove all connectors from the rear of
the microprocessor controller. Close the
control box. Connect the welder ground cable
as close as possible to the area being welded.
When welding is complete, remove the welder
ground cable. Reconnect the cables to the rear
of the microprocessor controller. Reconnect
the battery negative cable. Turn on the
microprocessor’s On/Off switch. Reset all
alarms and codes to their previous settings.
Run a full Pre-trip Inspection. Detailed
instructions can be found in Thermo King
Service Procedure A26A.
