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
WARNING: Keep hands and loose clothing clear of
fans and belts at all times when the unit is operating
with the doors open.
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.
10

Electrical Hazard
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.
Safety Precautions
Battery Installation and Cable
Routing
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.
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.
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.
CAUTION: Set all unit electrical controls to the OFF
position before connecting battery cables to the
battery to prevent unit from starting unexpectedly and
causing personal injury.
11
Safety Precautions
Refrigerant
Refrigerant Oil
Although fluorocarbon refrigerants are classified as safe, use
caution when working with refrigerants or in areas where they
are being used.
Observe the following precautions when working with or
around refrigerant oil:
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.
12
WARNING: Always wear goggles or safety glasses to
protect eyes from refrigerant oil contact.
WARNING: Protect skin and clothing from
prolonged or repeated contact with refrigerant oil.
Rubber gloves are recommended.

Unit Description
OptiSet Plus
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.
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.
points above 30F, the unit will operate in ECO Pulldown mode
until set point is achieved, possibly never operating in high
speed mode.
Operating the unit in low speed pulldown can save up to 15%
fuel during the initial pulldown without significantly
increasing the overall unit run time.
All Thermo King Multi-Temperature units come factory set
with the ECO Pulldown Mode enabled. Contact your Thermo
King dealer for further information about ECO Pulldown
Mode.
Defrost
ECO Pulldown Mode
Frost gradually builds-up on evaporator coils as a result of
normal operation. The unit uses hot refrigerant to defrost the
evaporator coil. Hot refrigerant gas passes through the
evaporator coil and melts the frost. The water flows through
collection drain tubes onto the ground. The methods of defrost
initiation are Automatic, and Manual.
This programmable feature allows the unit to operate in low
speed during initial pulldown until the temperature in any one
zone inside the trailer reaches 30F. At this point, it
automatically switches the unit to high speed operation. For set
Automatic Defrost: The SR-4 MT automatically initiates
timed or demand defrost cycles. The SR-4 MT microprocessor
can be programmed to initiate timed defrost cycles at intervals
of 2, 4, 6, 8, or 12 hours. Demand defrost cycles occur if the
22
Unit Description
differences between the return air temperature, discharge air
temperature, and coil temperature exceed certain limits. The
unit can enter defrost cycles as often as every 30 minutes if
required.
Manual Defrost: In Manual Defrost Mode, the operator
initiates a defrost cycle. See “Initiating a Manual Defrost
Cycle.”

Main Menu Features
Pretrip
A Pretrip Test verifies unit operation. This display allows a
Pretrip Test to be selected and initiated by the operator. If the
Pretrip Test is entered with the unit shut down a Full Pretrip
Test with device amp checks will be performed. If the Pretrip
Test is entered with the unit running in either diesel or electric
mode a Running Pretrip Test is performed. Test results are
reported as PASS, CHECK or FAIL when the Pretrip Test is
completed.
Pretrip Test Conditions
•
Current unit settings are saved and restored at the end of
the Pretrip Test or if the unit is turned off and back on.
•
Pretrip Test can be run in either Diesel or Electric Mode.
•
The unit will auto switch from Diesel Mode to Electric
Mode or from Electric Mode to Diesel Mode during a
Pretrip Test if these features are enabled and the auto
switch conditions occur.
Conditions where Pretrip Tests are not
Allowed
•
If any shutdown alarms are present. Pretrip tests are
allowed with some Check and Log alarms.
•
If the unit is in Sleep Mode.
•
If the unit is in Service Test Mode, Interface Board Test
Mode or Evacuation Mode.
Pretrip Test Considerations
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-4 units have high refrigeration capacity which results
in rapid temperature changes. Sensitive dry cargo may be
damaged as a result.
•
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.
57
Operating Instructions
•
•
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.
•

Loading and Enroute Inspections
This chapter describes pre-loading inspection procedures,
single temperature loading procedures, post loading, and
enroute inspection procedures for multi-temperature units.
Thermo King refrigeration units are designed to maintain the
required product load temperature during transit. Follow these
recommended loading and enroute procedures to help
minimize temperature related problems.
NOTE: When in doubt as to the correct refrigeration
requirements and/or loading procedures, call your company
office for instructions.
Pre-Loading Inspection
1.
2.
Make sure the unit is turned off before opening the doors
to minimize frost accumulation on the evaporator coil and
heat gain in the trailer. (Unit may be running when loading
the trailer from a warehouse with door seals.)
Spot check and record load temperature while loading.
Especially note any off-temperature product.
3.
Load the product so that there is adequate space for air
circulation completely around the load. DO NOT block
the evaporator inlets or outlets.
4.
Products should be pre-cooled before loading. Thermo
King transport refrigeration units are designed to maintain
loads at the temperature at which they were loaded.
Transport refrigeration units are not designed to pull hot
loads down to temperature.Verify that the setpoint
temperatures are correct for your cargo. Pre-cool the trailer
as required.
CAUTION: Cargo must be pre-cooled to the proper
temperature before loading. The unit is designed to
maintain temperature, not to bring a product to
temperature.
CAUTION: Push the controller access door firmly
closed after each use. Unit damage can occur in
transit if the door is not properly closed.
109

Single Temperature Loading
Procedures
Additional steps must be taken to insure load temperature
requirements are implemented and maintained when a
multi-temp unit is used to refrigerate a single-temperature load.
Trailer loading procedure will be different depending on how
temperature control has established for each trailer
compartment Zone. See “Operating the Unit in Single Zone
Mode” in the Operating Instructions chapter in this manual.
AMA719
Figure 136: Two Compartments, Same Setpoint
Temperature, Bulkheads In Place
In the example in Figure 136, each Zone could be individually
set to 35 F. The evaporator in each compartment will then
control the temperature in that compartment to the same 35 F
setpoint.
NOTE: Using the above method, it is recommended that the
bulkheads that separate each compartment be in place to
isolate the compartments.
Figure 137 shows two Zones that have the same setpoint. The
bulkhead separating the compartments has been removed. The
Host evaporator senses temperature and controls both
evaporators to the temperature setpoint.
AMA720
Figure 137: Two Compartments, Same Setpoint

Loading and Enroute Inspections
NOTE: Using Method 2, it is recommended that all
bulkheads be removed to create one large compartment.
Inspection Troubleshooting
1.
If a temperature reading is not within desired temperature
range, refer to the troubleshooting table on the following
pages. Correct problem as required.
2.
Repeat the Enroute Inspection every 30 minutes until the
compartment temperature is within desired temperature
range. Stop the unit if the compartment temperature is not
within desired temperature range on two consecutive 30
minute inspections, especially if the compartment
temperature appears to be moving away from the setpoint.
3.
Immediately contact the nearest Thermo King Service
Center or your company office.
4.
Take all necessary steps to protect and maintain proper
load temperature.
Post-Loading Inspection
1.
Make sure all the doors are closed and locked.
2.
Start the unit if it was shut off to load.
3.
Make sure the setpoints are at the desired settings.
4.
One-half hour after loading, manually initiate a Defrost
cycle. If the evaporator coil sensor temperature is below
45 F (7 C), the unit will Defrost. The microprocessor will
terminate Defrost automatically when the evaporator coil
temperature reaches 58 F (14.5 C) or the unit has been in
the Defrost mode for 30 or 45 minutes (depending on
setting).
Post Trip Checks
1.
Wash the unit.
2.
Check for leaks.
3.
Check for loose or missing hardware.
4.
Check for physical damage to the unit.
112
CAUTION: Stop the unit if the compartment
temperature remains more than the desired
temperature range from the setpoint on two
consecutive 30 minute inspections. Contact the
nearest Thermo King Service Center or your
company office immediately. Take all necessary steps
to protect and maintain proper load temperature.

Alarm Codes
Introduction
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.
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.
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.
NOTE: In some cases alarms cannot be cleared, or cannot be
cleared after they have occurred a specified number of times.
If such is the case, these alarms must be cleared by service
personnel. See “Clearing Alarm Codes” on page 118.
Alarm Types
The four types of alarms are described below.
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.
IMPORTANT: Always record any Alarm Codes that occur in the order that they occur - as well as any other pertinent
information. This information is extremely valuable to
service personnel.

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 139. 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 139. 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.
116
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 140). 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. If the unit is
configured for electric to diesel autoswitch, it automatically
starts and runs in Diesel Mode if an electric shutdown occurs.
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.

Clearing Alarm Codes
Most alarm codes can be cleared conventionally from the
Alarm Menu using the CLEAR Key. See the Operating
Instructions chapter for procedures.
The operator should contact a supervisor or a Thermo King
dealer about clearing alarms using the Guarded Access Menu.
Refer to the table on the following pages for alarm corrective
action.
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.
Take Immediate Action: An alarm condition exists that
will damage the unit or load. Take immediate action to correct
the problem.
118
NOTE: The corrective actions listed in the Operating
Instructions chapter and in the chart on the following pages
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.

Code Description
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.
5.
Remove the red cover from the positive (+) battery
terminal on the unit’s battery.

to the positive (+) battery terminal on the good battery.
8.
Connect the black negative (–) jumper cable to the
negative (–) battery terminal on the good battery. Do not
let the other end of the jumper cable touch anything that
conducts electricity.
9.
Connect the black negative (–) jumper cable to the lower
starter mounting bolt on the unit’s engine.

electricity.
10. If you are using a vehicle to jump start the unit, start the
vehicle and let it run for a few minutes. This will help
charge the discharged battery.

NOTE: Some units with microprocessors will show an
alarm code and will not try to start until the battery
voltage is above 10 volts.
12. After the unit starts, remove the jumper cables in reverse
order: black negative (–) from the unit starter mounting
bolt, black negative (–) from the good battery, red positive
(+) from the good battery, and red positive (+) from the
unit battery (that was discharged).
