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.
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.
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
•

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
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.
Automatic Start/Stop Operation
This unit is capable of automatic operation and could start at
any time without warning.
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.
Electrical Hazard
Refrigerant
Although fluorocarbon refrigerants are classified as safe, use
caution when working with refrigerants or in areas where they
are being used.
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.
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.

OptiSet Plus
Defrost
OptiSet™ Plus is a group of programmable functions that
control how the unit will operate with specific setpoints or
named products. This assures that when a particular setpoint or
named product is selected, the unit will always operate the
same way. This allows an entire fleet to be configured to match
the customers’ needs. Contact your Thermo King dealer for
information about programming OptiSet Plus.
Frost gradually builds-up on evaporator coils as a result of
normal operation. The unit uses hot refrigerant to defrost the

collection drain tubes onto the ground. The methods of defrost
initiation are Automatic, and Manual.
FreshSet
FreshSet™ is included in OptiSet Plus. FreshSet is a demand
base temperature control for fresh products. FreshSet modifies
and adjusts unit airflow operation to control temperature and to
maximize protection of cargo, while keeping operating costs to
a minimum. Contact your Thermo King dealer for information
about programming FreshSet.
Automatic Defrost: The controller automatically initiates
timed or demand defrost cycles. The controller can be
programmed to initiate timed defrost cycles at intervals of 2, 4,
6, 8, or 12 hours. Demand defrost cycles occur if the
differences between the return air temperature, discharge air
temperature, and coil temperature exceed certain limits. The

Manual Pretrip Inspection
(Before Starting the Unit)
Pretrip inspections are an important part of a preventative
maintenance program designed to minimize operating
problems and breakdowns. Perform this pretrip inspection
before every trip involving refrigerated cargo.
Engine Coolant: The engine coolant must have antifreeze
protection to -30 F (-34 C). Add coolant if Alarm Code 37 is
active. Check and add coolant to the expansion tank.
WARNING: Do not remove the expansion tank cap
while the coolant is hot.
NOTE: Pretrip inspections are not intended to take the place
of regular maintenance inspections.
Fuel: Make sure the diesel fuel supply is adequate to
guarantee engine operation to the next check point. Allow for
maximum fuel consumption of one gallon per hour of engine
operation.

Manual Pretrip Inspection
(Before Starting the Unit)
Pretrip inspections are an important part of a preventative
maintenance program designed to minimize operating
problems and breakdowns. Perform this pretrip inspection
before every trip involving refrigerated cargo.
NOTE: Pretrip inspections are not intended to take the place
of regular maintenance inspections.
Fuel: Make sure the diesel fuel supply is adequate to
guarantee engine operation to the next check point. Allow for
maximum fuel consumption of one gallon per hour of engine
operation.
Engine Oil: Check the engine oil level. It should be at the
Full mark when the dipstick is threaded all the way into the oil
pan. Do not overfill.
CAUTION: Turn the engine off before checking the
engine oil level.
Engine Coolant: The engine coolant must have antifreeze
protection to -30 F (-34 C). Add coolant if Alarm Code 37 is
active. Check and add coolant to the expansion tank.
WARNING: Do not remove the expansion tank cap
while the coolant is hot.
Battery: Make sure the battery terminals are tight and free of
corrosion.
Belts: Make sure belts are in good condition and adjusted to
the proper tension. For more information about belt tension,
see the Specifications chapter.
Electrical: Check the electrical connections to make sure they
are securely fastened. Wires and terminals should be free of
corrosion, cracks, and moisture.
Structural: Visually inspect the unit for leaks, loose or
broken parts, and other damage.

Manual Pretrip Inspection (Before Starting the Unit)
Damper: Make sure the damper in the evaporator air outlets
move freely, with no sticking or binding.
Coils: Make sure the condenser and evaporator coils are clean
and free of debris.
Cargo Box: Check the interior and exterior of the cargo box
for damage. Any damage to the walls or insulation must be
repaired.
Cargo Doors: Make sure that the cargo doors and weather
seals are in good condition. The doors should latch securely
and the weather seals should fit tightly.
Defrost Drains: Check the defrost drain hoses and fittings to
make sure they are open.

Check Alarm Code 96 (Low Fuel Level) is set when the
fuel level falls to 15%. The controller can be programmed
to set a shutdown Alarm Code 44 (Out of Fuel) when the
fuel level falls to 5%. Shutdown Alarm Code 44 can be
manually cleared with the CLEAR key. In that case it
becomes a check alarm and the unit will continue to run
until it runs out of fuel (if it is not refilled). Alarm Code 96
and Alarm Code 44 are both automatically reset when the
fuel tank is refilled above 25%.
NOTE: Shutdown Alarm Code 44 reappears when it is
manually cleared from the Alarms Menu. However, it
changes to a check alarm so the unit will now start after
you exit the Alarms Menu.

Pretrip Tests
A Pretrip test verifies unit operation. The Pretrip Menu allows
the operator to select and initiate a Pretrip Test. There are two
different Pretrip Tests, the Full Pretrip and the Running Pretrip.
The Pretrip Tests can be run in either Diesel or Electric mode.
•
Amp Checks – Each electrical control component is
energized and the current drawn is confirmed to be within
specification.
•
Engine or Electric Motor Start – The engine or electric
will start automatically.
•
Defrost – If the coil temperature is below 45 F (7 C), a
Defrost cycle is initiated.
•
Cool Check – The ability of the unit to cool in low speed is
checked.
•
RPM Check (Diesel Mode only) – If the unit is running in
the Diesel Mode, the engine RPM in high and low speed is
checked during the Cool Check.
•
Heat Check - The ability of the unit to heat in low speed is
checked.
•
Report Test Results – The test results are reported as
“PASS”, “CHECK” or “FAILED” when the Pretrip is
completed. If test results are Check or Failed, alarm codes
will exist to direct the technician to the source of the
problem.

Running Pretrip
Pretrip Test Issues
A Running Pretrip occurs when Pretrip is initiated after the
engine or electric motor is running. The Running Pretrip test
proceeds in the order shown below:
When performing a Pretrip Test, the following issues should be
considered.
•
If running a Pretrip Test on a trailer loaded with dry cargo,
insure that proper airflow can occur around the load. If the
load restricts airflow, false test results may occur. Also,
SR-2 units have high refrigeration capacity which results
in rapid temperature changes. Sensitive dry cargo may be
damaged as a result.
RPM Check (Diesel Mode only) – If the unit is running in
the Diesel Mode, the engine RPM in high and low speed is
checked during the Cool Check.
•
If running a Pretrip Test on a trailer that has just been
washed down, the extremely high humidity inside the
trailer may result in false test results.
•
Heat Check - The ability of the unit to heat in low speed is
checked.
•
•
Report Test Results – The test results are reported as
“PASS”, “CHECK” or “FAILED” when the Pretrip is
completed. If test results are Check or Failed, alarm codes
will exist to direct the technician to the source of the
problem.
If running a Pretrip Test on a trailer loaded with sensitive
cargo, monitor the load temperature during the test as
normal temperature control is suspended during pre-trip
operation.
•
Always perform Pretrip Tests with the trailer cargo doors
closed to prevent false test failures.
•
Defrost – If the coil temperature is below 45 F (7 C), a
Defrost cycle is initiated.
•
Cool Check – The ability of the unit to cool in low speed is
checked.

Alarm Codes
Introduction
Alarm Types
An alarm code is generated when the microprocessor senses an
abnormal condition. Alarms direct an operator or service
technician to the source of a problem.
The four types of alarms are described below.
Multiple alarms can be present at one time. All generated
alarms will be stored in memory until cleared by the operator.
Document all alarm occurrences and report them to the service
technician.
See “Alarms Menu” in the Operation Instructions Chapter for
information about viewing and clearing alarms.
Log Alarms: Log Alarms are indicated by the Log Alarms
screen, which appears for approximately 30 seconds (just
before the Standard Display appears) each time the unit is
turned on. The Alarm Display must be used to view the
existing alarms. This level of alarm serves as a notice to take
corrective action before a problem becomes severe.
Maintenance items such as a maintenance reminder hour meter
reaching its time limit are log alarms.
NOTE: Some alarms (3, 4, 74, 203, and 204) cannot be
cleared in the Alarms Menu, they must be cleared in the
Maintenance Menu or the Guarded Access Menu. Contact
your supervisor or a Thermo King dealer about clearing
those alarms.

Check Alarms: Check Alarms are indicated by the Alarm
Display in which the large Alarm Icon will appears on the
Standard Display as shown below in Figure 112. The Alarm
Menu must be used to view the existing alarms. This level of
alarm serves as a notice to take corrective action before a
problem becomes severe. The unit will run with check alarms
but some features and functions may be inhibited.
Prevent Alarms: Prevent Alarms are also indicated by the
Alarm Display as shown in Figure 112. The Alarm Menu must
be used to view the existing alarms. The unit may stop running
and wait a timed interval or until conditions allow and then
restart. If the unit is waiting to restart, Alarm Code 84 Restart
Null will be present along with the Prevent Alarm. In other
cases the unit may restart or run with reduced performance to
determine if continued operation is possible. If the alarm does
not reoccur with reduced performance the unit will then return
to full performance. If the unit is operating with reduced
performance Alarm Code 85 Forced Unit Operation will also
be present.

not reoccur with reduced performance the unit will then return
to full performance. If the unit is operating with reduced
performance Alarm Code 85 Forced Unit Operation will also
be present.
Alarm Codes
Shutdown Alarms: Shutdown Alarms are indicated by the
Alarm Display. Shutdown alarms also cause the display and
backlight to flash on and off, and the display will switch from
normal video to reverse video and back to normal video (light
areas become dark and dark areas become light as shown in
Figure 113). Shutdown alarms force the unit into shutdown.
The unit will remain in shutdown and will not restart until the
shutdown alarm is cleared. Exceptions are some engine and
electric shutdown alarms become that log alarms when
switched to the alternate operating mode (diesel to electric or
electric to diesel).
If a shutdown alarm occurs that affects only diesel mode
operation and the unit is switched to electric (either manually
or automatically), the diesel mode shutdown alarm becomes an
electric mode log alarm. This allows the unit to run in electric
mode without clearing the shutdown alarm that is preventing
diesel mode operation. If the unit is switched back to diesel
mode, the alarm again becomes a diesel mode shutdown alarm
and prevents unit operation.
In the same manner, if a shutdown alarm occurs that affects
only electric mode operation and the unit is switched to diesel
(either manually or automatically), the electric mode shutdown
alarm becomes a diesel mode log alarm to allow diesel mode
operation. If the unit is switched back to electric mode, the
alarm reverts to an electric mode shutdown alarm and prevents
unit operation.

Pretrip Alarm Codes
If an alarm occurs during a Pretrip Test the alarm code will be
displayed as Pretrip Alarm XX, where XX is the alarm code.

Corrective Action
The operator can repair certain faults, other faults can only be
repaired by your Thermo King Dealer. The operator can clear
some alarm codes, but some alarm codes (3, 4, 74, 203, and
204) can only be cleared by a technician. Contact your
supervisor or a Thermo King dealer about clearing those
alarms. Refer to the table on the following pages for the proper
corrective action.
NOTE: The corrective actions listed above and on the
following chart are suggestions only. Always consult your
company for final decisions.
NOTE: The chart on the following pages shows all possible
alarm codes for all possible applications. Not all codes will be
applicable to each individual unit.
NOTE: Document all alarm faults and report them to the
service technician.
There are three levels of corrective action that can be taken
when an alarm condition occurs.
OK To Run: An alarm condition exists but does not affect
unit operation. Corrective action can occur at a later date.
Check As Specified: An alarm condition exists that could
affect unit operation. Follow directions in the Corrective
Action column on the following chart.

Loading and Enroute Inspections
Inspection Troubleshooting
Problem
Cause
Remedy
A return air
temperature
reading is not
within desired
temperature
range of the
setpoint.
The unit has not
had time to cool
down to correct
temperature.
Refer to the load log history. Look for above temperature load records,
properly pre-cooled cargo compartment, length of time on road, etc. Correct
as required. Continue monitoring return air temperature until the reading is
within the desired temperature range of the setpoint.
The unit may have
a low refrigerant
charge.

Jump Starting
If the battery in a unit is discharged or run down, the unit may
be jump started using jumper cables and another battery or
vehicle. Consider the following precautions and be careful
when jump starting a unit.
WARNING: A battery can be dangerous. A battery
contains a flammable gas that can ignite or
explode. A battery stores enough electricity to burn
you if it discharges quickly. A battery contains
battery acid that can burn you. Always wear
goggles or safety glasses and personal protective
equipment when working with a battery. If you get
battery acid on you, immediately flush it with water
and get medical attention.
CAUTION: Unhook the semi tractor from the
trailer before using the tractor to jump start the
unit on the trailer. The negative ground circuit is
complete when the tractor is hooked to the trailer.
This can cause dangerous sparks when the positive
connection is made at the battery.
IMPORTANT: Make sure to use a 12-volt battery to jump
start the unit. If you are using a vehicle, make sure it has a
12-volt battery with a negative ground system. Do not use a
“hot shot” booster device or a 24-volt source.
Read and understand the following procedure completely
before connecting any jumper cables. Use good jumper cables
made with #2 gauge (or larger) cables.
1.
Make sure the unit is turned off. If you are using a vehicle,
make sure its ignition is also turned off.
2.
Open the front doors on the unit. The battery is located to
the right of the engine.
3.
Check the discharged battery to make sure it is not
damaged or frozen. Do not jump start a damaged or frozen
battery. Check the vent caps to make sure they are tight.
4.
Identify the positive (+) and negative (–) battery terminals.
