INTRODUCTION
3. They are stocked with genuine Thermo King
replacement parts.
4. The warranty on your new unit is valid when
the repair and/or replacement of component
parts is performed by an Authorised
Thermo King dealer.
Performing pre-trip checks on a regular basis will
minimise “on the road” operating problems. A
closely followed maintenance program will also
help keep your unit in top operating condition.
If factory recommended procedures are followed,
you will learn that you have purchased the most
efficient and dependable temperature
control system available.
GENERAL OPERATION
In truck-driven units, temperature control is based
on two values: The setting (Setpoint) of the
electronic thermostat and the evaporator return
temperature. The difference between these two
temperatures will determine the mode of
operation: cool, heat, or null.
•Cool: When the temperature in the load
compartment is higher than the setpoint, the
unit runs in cool mode to reduce the evaporator
return temperature.
•Heat: When the temperature in the load
compartment is lower than the setpoint, the unit
changes to heat mode to raise the evaporator
return temperature.
•Null: Once the Setpoint Temperature has been
reached, and while the temperature remains
between XºC/F above or below the setpoint,
there is no demand for transfer of heat or cold,
and the unit runs in null mode.
•Defrost: After a scheduled period of time in
cool mode, between 30 minutes and 8 hours,
the unit runs in this fourth mode of operation to
eliminate ice that has accumulated in the
evaporator or condenser coil. Defrost can be
initiated automatically or manually.
Factory setting for X is 3ºC (5ºF). During unit
installation, this value can be adjusted in
increments of 1ºC/F.
Units with R-134a refrigerant without defrost:
Temperatures can be controlled from 0ºC to
+22ºC (+32ºF to +71ºF).
Units with R-134a refrigerant with defrost:
Temperatures can be controlled from -10ºC to
+22ºC (+14ºF to +71ºF).
Units with R-404A refrigerant: Temperatures
can be controlled from -32ºC to +22ºC
(-26ºF to +71ºF).

SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
WARNING!
This unit is not intended for use by persons
(including children) with a physical, sensory or
mental impairment, or by persons without the
proper experience or knowledge, unless they
have been provided supervision or instruction
regarding the use of the unit by a person
responsible for their safety.
Children must be supervised to ensure they do
not play with the unit.
Thermo King recommends that all services be
performed by a Thermo King dealer. However,
there are several general safety practices which
you should be aware of:
1. When working with or around the refrigeration
system, always wear goggles or safety glasses.
Refrigerant or battery acid can cause permanent
damage if they come in contact with your eyes.
2. Never run the unit with the compressor
discharge valve closed.
3. Keep your hands and loose clothing clear of
fans and belts at all times when the unit is
running or when opening and closing the
compressor service valves.
4. If you need to drill holes in your unit for any
reason, use extreme caution. You could be
weakening structural components. Drilling into
electrical wiring or refrigerant lines could cause
a fire.
5. It is recommended that any service work on
evaporator or condenser coils be left for the
certified Thermo King technician but, should
you need to work around the coils, use extreme
caution as exposed coil fins can cause painful
lacerations.
REFRIGERANT
Although fluorocarbon refrigerants are classified
as safe, observe caution when working with
refrigerants or around areas where they are being
used in the servicing of your unit.
Fluorocarbon refrigerants evaporate rapidly,
freezing anything they contact if accidentally
released into the atmosphere from the liquid state.
The Fluorocarbon refrigerants used in the air
conditioning units may produce toxic gases
which, in the presence of an open flame or
electrical short, become severe respiratory
irritants capable of causing death.
FIRST AID - REFRIGERANT
EYES: If liquid comes into contact with the eyes,
flush with large amounts of water and get prompt
medical attention.
SKIN: Flush affected area with large amounts of
lukewarm water and keep cool. Cover burns with
dry, sterile, bulky dressings to protect from
infection or injury. Get medical attention.
INHALATION: Move victim to fresh air and
restore breathing if necessary. Stay with victim
until arrival of emergency medical personnel.
REFRIGERANT OIL
Always observe the following directions when
working with refrigerant oil:
EYES: Do not allow refrigerant oil to contact
your eyes.
SKIN: Do not allow prolonged or repeated contact
with skin or clothing.
IRRITATION: To prevent irritation, wash
thoroughly immediately after handling.
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 the irritation persists.
INHALATION: Move victim to fresh air and
restore breathing if necessary. Stay with victim
until arrival of emergency personnel.
INGESTION: Do not induce vomiting. Contact
local poison control centre or physician
immediately.

8
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.

OPERATING INSTRUCTIONS
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.
1. Leaks. Check for refrigerant leaks and worn
refrigerant lines.
2. Battery. Terminals should be properly tightened
and show no signs of corrosion.
3. Belts. Check for cracks, wear, and proper belt
tension.
4. Mounting bracket. Ensure that bolts are fully
tightened.
5. Electrical system. Electrical connections
should be securely fastened. Wires and terminals
should show no signs of corrosion, cracks or
dampness.
6. Structure. Visually check for physical damage.
7. Coils. The condenser and evaporator coils
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 inchand 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.
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.
9. Defrost Drains. Check the defrost drain hoses
and fittings to ensure they are not blocked.
10. Doors. Ensure that doors and weather seals
are in good condition and seal hermetically.
11. Sight glass. Check that the refrigerant charge
sight glass on the running unit is totally full (the
cargo compartment temperature must be
approximately 0ºC).

OPERATING INSTRUCTIONS
Note: Each Hour counter will be displayed in
hours when the counted value is <1000.
When the value will be >= 1000, the hours
number will be displayed alternatively between
hours and thousands, into “toh” or “coh”
folders.
For instance, if the counted value is 12055,
“055” will be displayed alternatively with “12”,
where the number with 3 digits is always the
number of “hours”, the number with 2 digits is
always the number of “thousand of hours”.
POST-START INSPECTION
Thermostat. Adjust the thermostat setting to
above and below the compartment temperature
to check thermostat operation (see Operating
Modes).
Pre-cooling. With the thermostat set at the desired
temperature, run the unit for half-an-hour to one
hour (or longer if possible) before loading the
truck. Pre-cooling eliminates residual heat and
acts as a good test of the refrigeration system.
Defrost. When the unit has finished pre-cooling
the truck interior - the evaporator temperature
should have dropped below 2ºC (35.6ºF) - initiate
a defrost cycle with the manual defrost switch.
The defrost cycle should stop automatically.
LOADING PROCEDURE
1. To minimise frost accumulation in the
evaporator coil and a heat increase inside the
load compartment, ensure that the unit is OFF
before opening the doors. (The unit may
continue to run when the truck is being loaded
in a warehouse with the doors closed.)
2. Carefully check and record the load
temperature when loading the truck. Note
whether any products are out of temperature
range.
3. Load the product in such a way that there is
sufficient space for the air to circulate
throughout the load. DO NOT block the
evaporator inlet or outlet.
4. Product should be pre-cooled before loading.
Thermo King units are designed to maintain the
load at the temperature at which it is loaded.
Transport refrigeration units are not designed to
reduce the load temperature.
PROCEDURE AFTER LOADING
1. Ensure that all doors are closed and locked.
2. Adjust the thermostat to the desired
temperature setpoint.
3. Start the unit.
4. Half an hour after loading the truck, defrost the
unit for a moment by pressing the Manual
Defrost switch. If the coil temperature drops to
below 2ºC (35.6ºF), the unit will defrost. The
defrost cycle should stop automatically.
WEEKLY PRE-TRIP CHECKS
1. Visually inspect belt.
2. Listen for unusual noises, vibrations, etc.
3. Visually inspect unit for fluid leaks (coolant,
oil, refrigerant).
4. Visually inspect unit for damaged, loose or
broken parts (including air ducts and
bulkheads, if so equipped).
5. In the event of excess of dirt or obstruction
clean the unit, including condenser and
evaporator coils.
WEEKLY POST-TRIP CHECKS
1. Clean the outside cover of the unit. Use a damp
cloth and neutral detergents. Do not use harsh
cleaning products or solvents.
CAUTION!
Do not use pressurised water.
2. Check for leaks.
3. Check for loose or missing hardware.
4. Check for physical damage to the unit.
