Chapter 3: Operation Instructions

3.1: Weekly Pre-Trip Inspections

The following weekly pre-trip inspection should be completed before loading the truck. Weekly inspection does not replace the regular maintenance inspections (see the scheduled maintenance inspection section); however, it is an important part of the preventive maintenance program to avoid operating problems before they occur.

Leaks. Inspect for refrigerant leaks and worn coolant lines.

Battery. Terminals should be properly tightened and show no signs of corrosion.

Belts. Check for cracks, wear, and proper belt tension.

Mounting Bracket. Ensure that bolts are fully tightened.

Electrical system. Electrical connections should be securely fastened. Wires and terminals should show no signs of corrosion, cracks or dampness.

Structural. Visually check for physical damage.

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 inch and 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.

Load Compartment. Inspect the interior and exterior of the truck for any damage. Any damage to the walls or insulation should be repaired.

Defrost Drains. Check the defrost drain hoses and fittings to ensure they are not blocked.

Doors. Ensure that doors and weather seals are in good condition and seal hermetically.

Sight Glass. Check that the refrigerant charge sight glass on the running unit is totally full (the cargo compartment temperature must be approximately 0ºC).

3.2: Starting the unit

Engine Operation

  1. Start the truck engine. The Dot Symbol will remain lit.

  2. Press the On/Off switch located in the In-cab Control Box for at least 1 second. The In-cab Control Box display will be activated.

  3. Check the setpoint, and adjust if needed.

Note Regular monitoring of the unit is recommended, the frequency of this monitoring will depend on the type of cargo.

3.3: Standard Display

This is the display that appears when the ON/OFF key is pressed 1 second and the unit started. It normally displays the return air temperature and the current operating mode with the appropriate symbol.

If there is an alarm, the alarm symbol will also be shown on the screen.

The example in the drawing shows: 10ºC temperature, cool mode.

3.4: Entering the setpoint temperature

The Setpoint Temperature can be quickly and easily changed.

  1. Press and release the SET key once, and the letters SP will appear on screen.

3.10: After Start Inspection

Thermostat. Dial the thermostat setting above and below the box temperature to check thermostat operation (see Operating Modes).

Pre-Cooling. With the thermostat set at the desired temperature, allow the unit to run for one-half to one hour (longer if possible) before loading the truck. Pre-cooling will remove residual body heat and moisture from the box interior and provide a good test of the cooling system.

Defrost. When the unit has finished pre-cooling the truck interior, the evaporator temperature should have dropped below 35.6°F (2°C); initiate a manual defrost cycle. The defrost cycle should stop automatically.

Chapter 4: Pretrip Inspection (Before Loading Refrigerated Cargo)

Pretrip inspections are an important part of preventative maintenance designed to minimize on-the-road operating problems. Perform this visual pretrip inspection before loading refrigerated cargo.

Note Pretrip inspections are not intended to take the place of regular maintenance inspections.

Visual Pretrip Inspection

Visual Pretrip Inspection

1. Check that engine driven compressor belt is in good condition.
2. Check that condenser inlet and outlet areas are clean and free of debris.
3. Check that evaporator inlet and outlet areas are clean and free of debris and the drain hoses are in place and operational.
4. Check that doors and seals are in good condition. Doors should latch securely and the seals should fit tightly.
5. Check interior and exterior of cargo box for damage. Any damage to walls or insulation must be repaired.

Chapter 5: Unit Operation and Loading Procedures

This chapter describes unit operation and proper loading procedures. Thermo King refrigeration units are designed to maintain the required product load temperature during transit. Transport refrigeration units are not designed to reduce the load temperature. Follow these recommended procedures to help prevent cargo spoilage.

5.1: Unit Operation (Before Loading Refrigerated Cargo)

Start Unit: Adjust the thermostat setting to above and below the compartment temperature to check thermostat operation.

Pre-Cooling: With the thermostat set at the desired temperature, run the unit for half-an-hour to one hour (or until the desired setpoint is reached) before loading the refrigerated cargo. Pre-cooling eliminates residual heat and acts as a good test of the refrigeration system.

Defrost: When the unit has finished pre-cooling the cargo box the evaporator temperature should have dropped below 36°F (2.2°C). Initiate a manual defrost cycle with the In-Cab Controller. The defrost cycle will stop automatically.

5.2: Loading Procedure

  1. Verify the unit is turned off before opening the doors to minimize frost accumulation on the evaporator coil and heat gain in the load compartment (Unit may be running when loading the truck from a warehouse with door seals).

  2. Carefully check and record the load temperature when loading the truck. Note whether any products are out of temperature range.

  3. 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.

  4. Load the product so that there is adequate space for air circulation completely around the load. DO NOT block the evaporator inlet or outlet.

Important 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.
Note To minimize frost accumulation in the evaporator coil and a heat increase inside the load compartment, ensure that the unit is OFF before opening the doors.

  1. Carefully check and record the load temperature when loading the refrigerated cargo. Note whether any products are out of temperature range.

  2. Load the product to verify sufficient air space is maintained around and through the load in compartment. Airflow around the cargo must not be restricted. DO NOT block the evaporator inlet or outlet. Refer to the Air Circulation Diagram on the following page.

  3. Minimize door opening times and close door(s) in between loading to preserve box temperature.

Air Circulation Diagram

Air Circulation Diagram

1. Evaporator air outlet not blocked by cargo.
2. Sufficient air space is maintained above cargo.
3. Good air circulation around and between cargo.
4. Cargo separated from bulkhead and walls a minimum of 4.00 inch (100 mm).
5. Evaporator air inlet not blocked by cargo.

5.3: Enroute Inspections

To help prevent damage to the cargo, complete the following enroute inspection every four hours.

Inspection Procedure

  1. Verify the setpoint is correct.

  2. Check the return air temperature readings. The temperature readings should be within the desired temperature range. If the readings are not within this range, refer to ( Inspection Troubleshooting).

Inspection Troubleshooting

  1. If a return air temperature reading is not within the desired temperature range, refer to ( Inspection Troubleshooting). Correct the problem as needed.

  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 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 Dealer.

  4. Take the necessary steps to protect and maintain proper load temperature.

Inspection Troubleshooting
Problem Cause Remedy
Return air temperature reading is not within desired temperature range of the setpoint. Unit has not had time to cool cargo to correct temperature. Refer to 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 reading is within desired temperature range of the setpoint.
  Unit may have a low refrigerant charge Contact nearest Thermo King dealer, or call the Thermo King Cold Line for referral.
  Unit is in defrost or has just completed a defrost cycle. Monitor return air temperature after defrost cycle is completed to see if temperature returns to desired temperature range of the setpoint.
Note Temperature will increase slightly during defrost cycle.
  Evaporator is plugged with frost. Initiate a manual defrost cycle. Defrost cycle will automatically terminate when complete. Continue monitoring return air temperature until reading is within desired temperature range of the setpoint.
Return air temperature reading is not within desired temperature range of the setpoint. Improper air circulation in the cargo compartment. Inspect unit and cargo compartment to determine if evaporator fans are working and properly circulating the air. Poor air circulation may be due to improper loading of the cargo or shifting of the load. Correct as required. Continue monitoring return air temperature until problem is corrected.
    Caution
  • Risk of Injury
  • The unit can start and run automatically any time the unit is turned on. Turn the unit 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.
  The unit did not start automatically. Contact nearest Thermo King dealer, or call the Thermo King Cold Line for referral.
  Air leaks in cargo box. Inspect cargo box for air leaks such as doors that are not fully closed or bad/missing door seals. Repair as necessary.

    Important

  1. For each additional meter (39") of hose extension, add 80g (0.17lb) of refrigerant.

  2. It is a good idea to utilise the WINTRAC tool to set compressor speed at an intermediate level (for example - 60Hz) during refrigeration charge. If the unit is charged with the compressor at full speed, overcurrent protection may trip.

  3. DO NOT overcharge the system. Checking the sight glass is free from bubbles may be misleading if the evaporator box is warm. Decrease the temperature of the box to 5ºC or below before checking the sight glass.

Chapter 7: Inspection and Service Intervals

7.1: 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.

7.1.1: Weekly Pretrip Inspection

The following Weekly Pretrip Inspection should be completed before starting the unit and loading the truck. While the weekly inspection in not a substitute for regularly scheduled maintenance inspections, it is important part of the preventive maintenance program designed to head off operating problems before they happen.

Leaks: Inspect for refrigerant leaks and worn refrigerant lines.

Battery: Terminals should be properly tightened and show no signs of corrosion.

Belts: Inspect for cracks, wear, and proper belt tension.

Mounting Bolts: Verify bolts are properly tightened.

Electrical: Electrical connections should be securely fastened. Wires and terminals should be free of corrosion, cracks, or moisture.

Structural: Visually check for physical damage.

Coils: The condenser and evaporator coils (evaporator coils in multi–temperature units) should be clean and free of debris.

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 inch and 3 inches (25 to 75 millimeters) from the coil surface.

    Important Models V–500 and V–800/V–1000 feature a high efficient micro channel aluminum condenser coil, in these cases the spray nozzle should be kept 300mm away from the coil and aimed perpendicularly to the coil surface to avoid damaging the aluminum fins.
    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.

Load Compartment: Inspect the interior and exterior of the truck for any damage. Any damage to the walls or insulation should be repaired.

Defrost Drains: Check the defrost drain hoses and fittings to ensure they are not blocked.

Doors: Verify doors and weather seals are in good condition and seal hermetically.

Sight glass: Check that the refrigerant charge sight glass on the running unit is totally full (the cargo compartment temperature must be approximately 0ºC).

7.2: Weekly Post-Trip Checks

    Notice
  • Equipment Damage
  • Do not use pressurised water.

  1. Clean the outside cover of the unit. Use a damp cloth and neutral detergents. Do not use harsh cleaning products or solvents.

  2. Check for leaks.

  3. Check for loose or missing hardware.

  4. Check for physical damage to the unit.

7.3: Inspection and Service Schedules

To ensure that your Thermo King unit operates reliably and economically over its full life, and to avoid limiting its warranty cover, the appropriate inspection and service schedule must be followed. Inspection and Service intervals are determined by the number of unit operating hours and by the age of the unit. Examples are shown in the table below. Your Dealer will prepare a schedule to suit your specific needs.

Operating Hours per Year 1000 2000 3000

  (continue as above) (continue as above) (continue as above)
Important Installation Inspection needs to be carried out on all the units at 6 months/ 500 hours (whichever occurs first).

Service Record

Each inspection and service performed should be recorded on the Service Record Sheet found at the back of this manual.

Preventative Maintenance

Refer to the previous page for checks that should be carried out daily/weekly on the unit. Please work with your Dealer in order to create a maintenance schedule which fits your needs.
Thermo King has extended the limited warranty on new units from 3,000 total hours to a maximum of 4,000 compressor run hours within the 2 year warranty period.
This limited warranty is dependent on the owner and/ or operator adhering to the preventative maintenance schedule as advised by your Thermo King Dealer.

Chapter 8: Recover Refrigerant

At Thermo King®, and FrigoBlock we recognize the need to preserve the environment and limit the potential harm to the ozone layer that can result from allowing refrigerant to escape into the atmosphere.

We strictly adhere to a policy that promotes the recovery and limits the loss of refrigerant into the atmosphere.

In addition, service personnel must be aware of Federal local regulations concerning the use of refrigerants and the certification of technicians. For additional information on regulations and technician certification programs, contact your local THERMO KING dealer.
