2.6: Defrost

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.

Automatic Defrost: The H.M.I. automatically initiates timed or demand defrost cycles. The H.M.I. 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 unit can enter defrost cycles as often as every 30 minutes if required.

Automatic Defrost: The SR-4 automatically initiates timed or demand defrost cycles. The SR-4 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 differences between the return air temperature, discharge air temperature, and coil temperature exceed certain limits.

Chapter 3: Manual Pretrip Inspection

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: Verify the diesel fuel supply is adequate to guarantee engine operation to the next check point. Allow for maximum fuel consumption of 3.8 Litres (one gallon) per hour of engine operation.

    Caution
  • Service Procedures
  • Turn the unit off before attempting to check the engine oil.

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
  • Hazardous Pressures
  • Do not remove expansion tank cap while coolant is hot.

Engine Coolant: The engine coolant must have antifreeze protection to -34 C (-30 F). Add coolant if alarm code s active. Check and add coolant to the expansion tank.

Note Refer to Specifications (Engine) where it is clearly states which coolant types are allowed to be used in this unit.

Battery: Verify the battery terminals are tight and free of corrosion.

Note All truck and trailer units will have a small battery drain when the unit is off. The battery can be drained even quicker if there are aftermarket options or third party devices connected to the unit which consume battery power.

This will cause the battery to become discharged over time.

Apart from the obvious inconvenience of having to charge the battery, it is also liable to damage battery cell material and cause the life of the battery to be shorter than acceptable.

Therefore, to ensure the battery remains in optimum condition during periods when the unit is not being used, Thermo King strongly recommends to switch on the unit at least once each week and run for 30 minutes or longer to keep the battery safe.

If the EnergyONE battery is drained after a long idle period, it will need to be recharged using an automatic programmable battery charger (Thermo King does not recommend the use of manual battery chargers on dry cell batteries).

Failure to do so may result in warranty for the battery being rejected.

Alternatively, Thermo King offers a solar panel option which would negate the requirement to switch off the microprocessor switch during long unit idle periods. For more information, please contact your local Thermo King dealership.

Compressor:

Important To maintain the integrity of the compressor shaft seal and to prevent loss of refrigerant, it is recommended to run the unit at least once each week for 30 minutes or longer.

Belts: Verify 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 verify 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.

Coils: Verify condenser and evaporator coils are 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.

  • 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. Verify 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.

    Notice
  • Equipment Damage
  • Failure to comply with above mentioned guidelines will lead to a shortened life of the equipment to an indeterminable degree and also may void your warranty.
Note 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.

Cargo Box: Check the interior and exterior of the cargo box for damage. Any damage to the walls or insulation must be repaired.

Note On trailers equipped with units qualified for pharmaceutical applications - under ThermoKing protocol inspect the integrity of the air chute.

Cargo Doors: Verify 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 to verify they are open and are equipped with one way kazoo valves at the drain exit.

TracKing Module:

  • Check that the module is turned on and communicating.

  • For Whisper Pro Enabled TracKing, it is recommended to check at some stage throughout your journey if the Advanced Controller automatically switches to “High Speed Lock Out” in an area designated for this - i.e., PIEK assigned Zone.

      Note

    1. For more information on how to set up PIEK assigned Zones, please refer to your unit installation manual, please contact your Thermo King Dealer Representative..

4.1: Microprocessor On/Off Switch

The microprocessor On/Off switch is located behind the lower roadside panel inside the Engine compressor bay compartment. This switch supplies or removes all electrical power to the microprocessor control system and all electrical circuits.

The switch must be in the ON position for the unit to operate.

The switch should be placed in the OFF position only when servicing the unit or if the unit is not going to be operated for one week or longer. Placing the switch in the OFF position will help prevent parasitic battery voltage loss and a dead battery.

  • 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, verify 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.

  • 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 includes all tests. A Running Pretrip Test is started with the engine or electric motor running.

  • Engine Start - The Engine will start automatically.

  • ETV Test - The ETV functionality is checked by closing and opening the ETV and determining an expected change in suction pressure.

  • Speed Test - The expected RPM for engine speed, condenser fan speed, and evaporator fan speed in a high and low speed is checked.

  • Cool Test - The ability of the unit to cool is checked.

  • Heat Test - The ability of the unit to heat is checked.

  • Defrost Test - If the coil temperature is below 14 °C, a defrost cycle is initiated.

  • Cool Return Test - The ability of the unit to return to cool is checked.

  • Report Test Results - The test results are reported as COMPLETED or FAIL when the Pretrip Test is completed. If test result is FAIL or if the unit did not PASS each test step, alarm codes will exist to direct the technician to the source of the problem.

A Check alarm is indicated by a check alarm notification on the display located next to the setpoint. The Check 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. If a Check alarm condition occurs while the unit is running, the alarm icon will appear in the display.

Prevent Shutdown Alarm

A Prevent Shutdown alarm is indicated by an Alarm Active enlarged red icon in the center of the display. The Alarm Active icon will appear. The unit will 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. In some cases, the unit will restart with reduced performance to determine if continued operation is possible. If the alarm does not reoccur with reduced performance, the unit will return to full performance. In general, if the alarm condition reoccurs a defined number of times, the alarm is set as a Shutdown alarm and no further restarts are possible.

Note If the Restart After Shutdown feature in the Guarded Access Menu is set as DISABLED, the control system will regard all prevent shutdown alarms as standard shutdown alarms.

Shutdown Alarm

A Shutdown alarm is indicated by an Alarm Active enlarged red icon in the center of the display. If a Shutdown alarm occurs while the unit is running, it will be indicated by all of the following:

  • The Alarm Active icon will appear.

  • The optional remote alarm light will flash on and off.

  • The optional remote status light (triple combo) will flash on and off.

Shutdown alarms will force the unit into shutdown. The unit will remain in shutdown until the Shutdown alarm is manually cleared.

Exceptions are some engine and electric Shutdown alarms that become Info Log events when switched to the alternate operating mode (diesel to electric or electric to diesel).

Chapter 6: Loading and Inspection Procedures

This chapter describes pre-loading inspections, loading procedures, post-loading procedures, post-loading inspections, and enroute inspections. Thermo King FRIGOBLOCK 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.

6.1: Pre-Loading Inspection

  1. Pre-cool products before loading. Note any variances on the manifest.

  2. Inspect door seals and vent doors for condition and a tight seal with no air leakage.

  3. Inspect the trailer inside and out. Look for:

    • Damaged or loose trailer skin and insulation

    • Damaged walls, air ducts, floor channels, or “T” flooring

    • Clogged defrost drain tubes

    • Blocked return air bulkhead

  4. Verify that the setpoint temperature is correct for your cargo. Pre-cool the trailer as required.

  5. Supervise product loading to ensure sufficient air space around and through the load. Airflow around cargo must not be restricted. It must be possible for air to flow around the goods within the refrigerated body. The return flow of air to the evaporator is ensured by means of the correct use of pallets or roll cages (e.g. they should never be film-wrapped down to the ground).

    Note If the warehouse is not refrigerated, operate the unit with the doors closed until cargo is ready to be loaded. Then turn off the unit, open the cargo doors and load cargo. When cargo is loaded, close trailer doors and restart the unit. The unit can be operated with the cargo box doors open if the truck is backed into a refrigerated warehouse and the dock door seals fit tightly around the trailer.

  1. Observe the guidelines for load securing. Pay attention to the load height. Telescopic bars securing the load must not be positioned beneath the flat evaporators.

Loading Considerations
1. Correct load height (trailers without chutes) 6. Clear defrost drains
2. Tight doors and seals 7. Good outside air circulation
3. Good air circulation around load 8. Unit inspection
4. Proper cargo temperature (prior to loading) 9. Tight seals
5. Interior/exterior walls and insulation in good condition 10. Maximum load height followed

3. Gaskets Equally Compressed 7. Cargo at Proper Temperature Prior to Loading
4. Clear defrost drains 8. Interior/exterior walls and insulation in good condition

6.2: Post-Loading Inspection

Post-loading inspections verify the cargo has been loaded properly. To perform a post-load inspection:

  1. Inspect the evaporator outlets for blockage.

  2. Turn the unit off before opening the cargo box doors to maintain efficient operation.

    Note The unit can be operated with the cargo box doors open if the truck is backed into a refrigerated warehouse and the dock door seals fit tightly around the trailer.

  3. Perform a final check of the load temperature. If the load is above or below temperature, make a final notation on the manifest.

    Important Cargo must be pre-cooled to proper temperature before loading. The unit is designed to maintain temperature, not cool an above-temperature load.

  4. Close or supervise the closing of the cargo box doors. Verify they are securely locked.

  5. Verify the setpoint is at the temperature listed on the manifest.

  6. If the unit was stopped, restart using the correct starting procedure. See the Operating Instruction chapter in this manual.

  7. Start a manual defrost cycle 30 minutes after loading. See the Manual Defrost procedure in the manual.

6.3: 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 ( Inspection Troubleshooting). 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 Thermo King or FRIGOBLOCK Dealer or your company office.

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

      5. Notice
    • Cargo Loss
    • 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 Thermo King or FRIGOBLOCK Dealer or your company office immediately. Take all necessary steps to protect and maintain proper load temperature.
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. 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.
Note Ensure cargo is properly pre-cooled prior to loading onto trailer. If 'warm cargo' is loaded onto trailer and reefer is used to cool to setpoint this will result in longer time required to cool down to correct temperature and possibly plugging of evaporator with frost due to increased humidity in trailer compartment.
The unit may have a low refrigerant charge. 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 dealer, authorized Service Center, or call the Thermo King Cold Line for referral. Consult the Table of Contents for Cold Line information or refer to Emergency Assistance section for contact information..
The unit is in defrost or has just completed a defrost cycle. 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.
The evaporator is plugged with frost. 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.
Improper air circulation in the cargo compartment. 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 depending on unit, fan belt slippage or faulty electrical fans. Correct as required. Continue monitoring return air temperature until problem is corrected.
The unit did not start automatically. Determine the cause for not starting. Correct as required. Continue monitoring return air temperature until reading is within desired temperature range of the setpoint.

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.

A multi-temperature unit may not have the cooling or heating capacity to maintain a specific temperature range throughout an entire trailer.
