Safety Precautions
Danger, Warning, Caution, and Notice
Thermo King ® recommends that all service be performed by a Thermo King dealer and to be aware of several general safety practices.
Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this unit depend upon the strict observance of these precautions.
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury and unsafe practices.
Indicates a situation that could result in equipment or propertydamage only accidents.
General Safety Practices
Keep hands and loose clothing clear of fans and belts at all times when the unit is operating with the doors open.
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 TK 56171-2-OP-EN
Exposed coil fins can cause lacerations. Service work on the evaporator or condenser coils is best left to a certified Thermo King technician.
Automatic Start/Stop Operation
The unit can start and run automatically any time the unit is turned on. Turn the Microprocessor On/Off switch Off before doing inspections or working on any part of the unit. Please note that only Qualified and Certified personnel should attempt to service your Thermo King unit.
Electrical Hazard
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.
Battery Installation and Cable Routing
An improperly installed battery could result in a fire, explosion, or injury. A
Thermo King approved battery must be installed and properly secured to the battery tray.
Improperly installed battery cables could result in a fire, explosion, or injury. Battery cables must be installed, routed, and secured properly to prevent them from rubbing, chaffing, or making contact with hot, sharp, or rotating components.
TK 56171-2-OP-EN 11
Do not attach fuel lines to battery cables or electrical harnesses. This has the potential to cause a fire and could cause serious injury or death.
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.
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.
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.
Do not connect other manufacturer’s equipment or accessories to the unit unless approved by Thermo King. Failure to do so can result in severe damage to equipment and void the warranty.
Refrigerant
Although fluorocarbon refrigerants are classified as safe, use caution when working with refrigerants or in areas where they are being used.
12 TK 56171-2-OP-EN
Refrigerant in the presence of an open flame, spark, or electrical short produces toxic gases that are severe respiratory irritants which can cause serious injury or possible death.
Do not inhale refrigerant. Use caution when working with refrigerant or a refrigeration system in any confined area with a limited air supply.
Refrigerant displaces air and can cause oxygen depletion, resulting in suffocation and possible death.
Refrigerant in a liquid state evaporates rapidly when exposed to the atmosphere, freezing anything it contacts. Wear butyl lined gloves and other clothing and eye wear when handling refrigerant to help prevent frostbite.
Refrigerant Oil
Observe the following precautions when working with or around refrigerant oil:
Protect your eyes from contact with refrigerant oil. The oil can cause serious eye injuries. Protect skin and clothing from prolonged or repeated contact with refrigerant oil. To prevent irritation, wash your hands and clothing thoroughly after handling the oil. Rubber gloves are recommended.

EL EC SH OC
Take IMMEDIATE action after a person has received an electrical shock. Get quick medical assistance, if possible.
The source of the shock must be quickly stopped, by either shutting off the power or removing the victim. If the power cannot be shut off, the wire
14 TK 56171-2-OP-EN
should be cut with an non-conductive tool, such as a wood-handle axe or thickly insulated cable cutters. Rescuers should wear insulated gloves and safety glasses, and avoid looking at wires being cut. The ensuing flash can cause burns and blindness.
If the victim must be removed from a live circuit, pull the victim away with a non-conductive material. Use wood, rope, a belt or coat to pull or push the victim away from the current. DO NOT TOUCH the victim. You will receive a shock from current flowing through the victim’s body. After separating the victim from power source, immediately check for signs of a pulse and respiration. If no pulse is present, start Cardio Pulmonary Resuscitation
(CPR). If a pulse is present, respiration might be restored by using mouth-tomouth resuscitation. Call for emergency medical assistance.
AS HY
Move victim to fresh air and use Cardio Pulmonary Resuscitation (CPR) or mouth-to-mouth resuscitation to restore breathing, if necessary. Stay with victim until emergency personnel arrive.

Pretrip
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 not running, 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, Output 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, these 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.
TK 56171-2-OP-EN 65
• 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.
Pretrip Test Sequence
Pretrip tests proceed in the order shown below. A Full Pretrip Test is started with the engine or motor not running and includes all tests. A Running

If the host unit is turned on, zone conditions are monitored even if the zone is turned off. For example, temperature sensor Alarm Codes 02, 03, and 04 can be set for a zone even when that zone is turned off.
Low Battery Voltage
If Alarm Code 61 Low Battery Voltage is set as a Shutdown Alarm, no subsequent alarm codes will be set with the exception of Alarm Code 28
Pretrip Abort.
Alarm Codes When Switching Between Diesel and Electric
If a shutdown alarm occurs that affects only diesel mode operation and the unit is switched to electric, 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 become 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, 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. If the unit is configured for electric to diesel Auto-Switch, it automatically starts and runs in diesel mode if an electric shutdown occurs.
Clearing Alarm Codes
Most alarm codes can be cleared conventionally from the Alarm Menu using the CLEAR Key.
The following control and display sensor alarm codes can only be cleared from the Guarded Access Menu:
• Alarm Code 03 Check Control Return Air Sensor
• Alarm Code 04 Check Control Discharge Air Sensor

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 Operator’s Instructions Chapter for information about viewing and clearing alarms.
occur – as well as any other pertinent information. This information is extremely valuable to service personnel.
1. 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.
2. 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 a service technician.
Alarm Types
There are four types of alarms.
Log Alarms
Log Alarms are indicated for 30 seconds each time the unit is turned on. This level of alarm serves as a notice to take corrective action before a problem becomes severe. Maintenance items such as maintenance hourmeter timeouts are Log Alarms. The TemperatureWatch ™ screen is not disabled if only
Log Alarm(s) are active.
When the unit is turned on, the display will show the Thermo King Logo and then the “Configuring System” message. If Log Alarm(s) are present, the
Log Alarm notice will appear on the display for 30 seconds. The remote indicator alarm light (if installed) will also be on during this period. After 30
112 TK 56171-2-OP-EN
seconds, the Standard Display will appear and the remote indicator alarm light will go off.
Figure 139.
Log Alarms Screen
Check Alarms
Check Alarms are indicated by a steady alarm indication at the top of the display and the message “Service Required within 24 Hours”. The Alarm
Icon will appear. 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. The
TemperatureWatch screen is disabled if a Check Alarm is active.

• If installed, the optional remote indicator light will indicate an alarm condition exists.
TK 56171-2-OP-EN 113
• The unit may be temporarily shut down if a Prevent Alarm is active. The unit will remain shut down for a timed restart interval or until the fault conditions are corrected and then restart if necessary.
• If the unit is in a temporary shutdown, Alarm Code 84 will be present along with the associated Prevent Alarm.
• In some cases, the unit will restart with reduced performance to determine if continued operation is possible.
• If the unit is operating with reduced performance, Alarm Code 85 may also be present.
If the alarm does not reoccur with reduced performance, the unit will return to full performance. In general, if the alarm condition occurs a specified number of times in a specified time interval, the alarm is set as a Shutdown
Alarm and no further restarts are possible.
set for CONTINUOUS, an unlimited number of restart attempts are allowed.
Zone Specific Prevent Alarms
A zone specific Prevent Alarm will force the affected zone into a temporary shutdown, but allow the unit to continue to run as required by the host unit or other zones.
• A small alarm icon will appear next to the affected zone.
• If installed, the optional remote indicator light will indicate an alarm condition exists.
• If zone specific Prevent Alarms occur in all zones, the unit will be forced into a unit level prevent shut down.
• The TemperatureWatch screen is disabled any time a zone specific
Prevent Alarm is active.
Unit Level Shutdown Alarms
Shutdown Alarms are indicated by all of the following:
• The unit will be shut down.
• The alarm icon will appear.
• The display and backlight will flash on and off.
• The display will switch from normal to inverted and back (light areas become dark and dark areas become light.)
114 TK 56171-2-OP-EN
• If installed, the optional remote indicator light will indicate an alarm condition exists.

Exceptions are some engine and electric Shutdown Alarms that become Log
Alarms when switched to the alternate operating mode (diesel to electric or electric to diesel). The TemperatureWatch screen is disabled any time a unit level Shutdown Alarm is active.
Zone Specific Shutdown Alarms
A zone specific Shutdown Alarm will force the affected zone to shut down, but allow the unit to continue to run as required by the host unit or other zones.
• A small alarm icon will appear next to the affected zone and blink with a period of ½ second on - ½ second off.
• If zone specific Shutdown Alarms occur in all zones, the unit will shut down and Alarm Code 114 will be set.
• If installed, the optional remote indicator light will indicate an alarm condition exists.
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.
Clearing Alarm Codes
Most alarm codes can be cleared conventionally from the Alarm Menu using the CLEAR soft 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 ( Table 1, p. 116 )
for alarm corrective action.
There are three levels of corrective action that can be taken when an alarm condition occurs.

Loading and Inspection Procedures
This chapter describes pre-loading inspections, loading procedures, postloading procedures, post-loading inspections and enroute inspections.
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.
loading procedures, call your company office for instructions.
Pre-Loading Inspection
Cargo must be pre-cooled to the proper temperature before loading. The unit is designed to maintain temperature, not cool an above-temperature load.
Push the controller access door firmly closed after each use. Unit damage can occur in transit if the door is not properly closed.
1. 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.)
2. 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.

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. Refer to ( “Operating the Unit in Single Zone Control
) in the Operating Instructions chapter in this manual.
In the example ( Figure 142, p. 128
), 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.

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
128 TK 56171-2-OP-EN
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.
Enroute Inspections
Complete the following enroute inspection every four hours. This will help minimize temperature related problems.
Inspection Procedure
1. Verify setpoint is correct.
2. Check the return air temperature reading. It should be within the desired temperature range.
3. Initiate a manual defrost cycle after each enroute inspection.
Inspection Troubleshooting
1. If a temperature reading is not within the desired temperature range,
refer to the troubleshooting table ( Table 2, p. 130
). Correct problem as required.
2. Repeat the Enroute Inspection every 30 minutes until the compartment temperature is within the desired temperature range. Stop the unit if the compartment temperature is not within the 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.
TK 56171-2-OP-EN 129
Stop the unit if the compartment temperature remains higher 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.
Table 2.
Inspection Troubleshooting
Problem: A return air temperature reading is not within desired temperature range of the setpoint.
Cause Remedy
The unit has not had time to cool down to correct temperature.
The unit may have a low refrigerant charge.
The unit is in defrost or has just completed a defrost cycle.
The evaporator is plugged with frost.
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 witin the desired temperature range of the setpoint.
Check the receiver tank sight glass for refrigerant level. If fluid is not showing in the receiver tank sight glass, the refrigerant charge may be low. A competent refrigeration technician is required to add refrigerant or repair the system. Contact the nearest Thermo King dealer, authorized Service Center, or call the Thermo King Cold Line for referral. Consult the Table of Contents for Cold Line information.
Monitor the return air temperature after the defrost cycle is completed to see if the temperature returns to the desired temperature range of the setpoint.
Improper air circulation in the cargo compartment.
Initiate a manual defrost cycle. The defrost cycle will automatically terminate when complete. Continue monitoring the return air temperature until the reading is within the desired temperature range of the setpoint.
Inspect the unit and cargo compartment to determine if the evaporator fan(3) are working properly circulation the air. Poor air circulation may be due to improper loading of the cargo, shifting of the load, or fan belt slippage. Correct as required. Continue monitoring return air temperature until problem is corrected.
130 TK 56171-2-OP-EN
Table 2.
Inspection Troubleshooting (continued)
Problem: A return air temperature reading is not within desired temperature range of the setpoint.
Remedy Cause
The unit did not start automatically.
Multi-Temp Units
Only – The unit is being used to cool/ heat a single temperature load and does not have the capacity to cool the entire trailer.
Determine the cause for not starting. Correct as required. Continue monitoring return air temperature until reading is within desired temperature range of the setpoint.
A multi-temperature unit may not have the cooling or heating capacity to maintain a specific temperature range throughout an entire trailer.
TK 56171-2-OP-EN 131
Jump Starting
If unit battery is discharged or run down, 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.
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.
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.
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 and jumper cables. Use good jumper cables made with #2 gauge (or larger) cables.
1. Verify unit is turned off. If you are using a vehicle, verify its ignition is also turned off.
2. Open front doors on unit. Battery is located on the right of engine.
3. Check discharged battery to verify it is not damaged or frozen. Do not jump start a damaged or frozen battery. Check vent caps to verify they are tight.
4. Identify positive (+) and negative (–) battery terminals.
5. Remove red cover from positive (+) battery terminal on the unit’s battery.

8. Connect the black negative (–) jumper cable to the negative (–) battery terminal on a 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.
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.
Keep your hands, clothing, and tools clear of fans and/or belts when working on a unit that is running or when opening or closing compressor service valves. Loose clothing might entangle moving pulleys or belts, causing serious injury or possible death.
11. Turn the unit on and let it start automatically or start it manually. If the unit will not crank or start, contact a qualified technician.
not try to start the unit until 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).
