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. 13 Safety Precautions Thermo King recommends that servicing be done only by a Thermo King dealer.

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. • 99 Operating Instructions Running Pretrip Pretrip Test Issues A Running Pretrip occurs when Pretrip is initiated after the engine or electric motor is running.

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. Figure 113: Shutdown Alarm Display 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. 139 Alarm Codes Shutdown Alarms: Shutdown Alarms are indicated by the Alarm Display.

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. 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 the cargo must not be restricted. NOTE: If the warehouse is not refrigerated, operate the unit with doors closed until cargo is ready to be loaded. Then turn off the unit, open 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. 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.
