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

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.
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.

Safety Precautions
12
Automatic Start/Stop Operation
This unit is capable of automatic operation and could start at
any time without warning.
Electrical Hazard
Battery Installation and Cable
Routing
WARNING: The unit can start at any time without
warning. Press the OFF key on the control panel and
place the microprocessor On/Off switch in the Off
position before inspecting or servicing any part of the
unit.
DANGER: Dangerous three phase AC electric power
is present whenever the unit is operating in either
Diesel Mode or Electric Mode and whenever the unit
is connected to a source of external standby power.
Voltages of this magnitude can be lethal. Exercise
extreme caution when working on the unit.
WARNING: Improperly installed battery could result
in a fire or explosion. A Thermo King approved
battery must be installed and properly secured to the
battery tray.
WARNING: Improperly installed battery cables could
result in fire or explosion. Battery cables must be
installed, routed and secured properly to prevent
them from rubbing, chaffing or making contact with
hot, sharp or rotating components.
WARNING: Do not attach fuel lines or any
additional wiring harnesses to the battery cables as
this could cause an electrical fire.
CAUTION: Do not connect other manufacturer’s
equipment or accessories to the Thermo King unit.
This could result in severe damage to equipment and
void the warranty.

Safety Precautions
13
Refrigerant
Although fluorocarbon refrigerants are classified as safe, use
caution when working with refrigerants or in areas where they
are being used.
CAUTION: Set all unit electrical controls to the OFF
position before connecting battery cables to the
battery to prevent unit fromstarting unexpectedly and
causing personal injury.
CAUTION: Always wear protective clothing, gloves
and eye wear when handling and installing batteries.
Battery acid can cause serious burns when exposed to
eyes or skin. If battery acid contacts skin or clothing,
wash immediately with soap and water. If acid enters
your eye, immediately flood it with running cold
water for at least twenty minutes and get medical
attention immediately.
CAUTION: Always cover battery terminals to prevent
them from making contact with metal components
during battery installation. Battery terminals
grounding against metal could cause the battery to
explode.
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.

Safety Precautions
14
Refrigerant Oil
Observe the following precautions when working with or
around refrigerant oil:
First Aid
First Aid–Refrigerant
Eyes: For contact with liquid, immediately flush eyes with
large amounts of water. Get prompt medical attention.
Skin: Flush areas with large amounts of warm water. Do not
apply heat. Wrap burns with dry, sterile, bulky dressing to
protect from infection or injury. Get prompt medical attention.
Inhalation: Move victim to fresh air and restore breathing if
necessary. Stay with victim until emergency personnel arrive.
First Aid–Refrigerant Oil
Eyes: Immediately flush eyes with large amounts of water for
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
