Introduction
There is nothing complicated about operating and maintaining
your Thermo King unit, but a few minutes studying this
manual will be time well spent.
Performing pre-trip checks and enroute inspections on a
regular basis will minimize on-the-road operating problems. A
regular maintenance program will also help to keep your unit
in top operating condition. If factory recommended procedures
are followed, you will find that you have purchased the most
efficient and dependable temperature control system available.
All service requirements, major and minor, should be handled
by a Thermo King dealer for four very important reasons:
• They are equipped with the factory recommended tools to
perform all service functions
• They have factory trained and certified technicians
• They have genuine Thermo King replacement parts
• The warranty on your new unit is valid only when the
repair and replacement of component parts is performed
by an authorized Thermo King dealer.
IMPORTANT: This manual is published for informational
purposes only and the information furnished herein should
not be considered as all-inclusive or meant to cover all
contingencies. If more information is required, consult your
Thermo King Service Directory for the location and
telephone number of the local dealer.

Safety Precautions
Thermo King recommends that servicing be done only by a
Thermo King dealer. However, you should be aware of several
safety practices. This chapter gives basic safety precautions for
working with Thermo King units and describes the safety
stickers on your unit that you should be familiar with.
General Safety Practices
DANGER: NEVER operate the unit with the
compressor discharge valve closed. Doing so could
cause the compressor to explode, causing death or
serious injury.
WARNING: Always wear goggles or safety glasses
when working with or around the refrigeration system
or battery. Refrigerant or battery acid can cause
permanent damage if it comes in contact with your
eyes.
WARNING: Keep hands and loose clothing clear of
fans and belts at all times when the unit is operating
or when opening or closing compressor service
valves.
WARNING: Exposed coil fins can cause painful
lacerations. Service work on the evaporator or
condenser coils should be done by a certified Thermo
King technician.
WARNING: Do not apply heat to a closed cooling
system. Before applying heat to a cooling system,
drain it. Then flush it with water and drain the water.
Antifreeze contains water and ethylene glycol. The
ethylene glycol is flammable and can ignite if the
antifreeze is heated enough to boil off the water.

Safety Precautions

Automatic Start/Stop Operation
This unit is capable of automatic operation and could start at
any time without warning.
Electrical Hazard
Refrigerant
Although fluorocarbon refrigerants are classified as safe, use
caution when working with refrigerants or in areas where they
are being used.
CAUTION: Use extreme caution when drilling holes
in the unit. Drilling into electrical wiring or
refrigerant lines could cause a fire. Do not drill into
structural components.
WARNING: The unit can start at any time without
warning. Press the OFF key on the HMI control panel
and place the microprocessor On/Off switch in the
Off position before inspecting or servicing any part of
the unit.
CAUTION: Turn off the high voltage power supply
and disconnect the electric cable before working on
the unit. Units with electric standby present a
potential electrical hazard.
DANGER: Fluorocarbon refrigerants can produce
toxic gases. In the presence of an open flame or
electrical short, these gases are severe respiratory
irritants CAPABLE OF CAUSING DEATH.
DANGER: Fluorocarbon refrigerants tend to
displace air and can cause oxygen depletion which
could result in DEATH BY SUFFOCATION. Provide
adequate ventilation in enclosed or confined areas.
WARNING: Fluorocarbon refrigerants evaporate
rapidly, freezing anything they contact if accidentally
released into the atmosphere from the liquid state.

at least 15 minutes while holding the eyelids open. Get prompt
medical attention.
Skin: Remove contaminated clothing. Wash thoroughly with
soap and water. Get medical attention if irritation persists.
Inhalation: Move victim to fresh air and restore breathing if
necessary. Stay with victim until emergency personnel arrive.
Ingestion: Do not induce vomiting. Immediately contact
