Loading Procedure
1. Make sure that the unit is Off before opening the doors
to minimize frost accumulation on the evaporator coil
and heat gain in the trailer. (The unit may be running
when the truck is being loaded from a warehouse with
door seals.)
2. Spot check and record the load temperature while load-
ing. Especially note any off-temperature product.
3. Load the product so there is adequate space for air cir-
culation completely around the load. DO NOT block
the evaporator inlet or outlet.
4. Products should be precooled before loading. Thermo
King units are designed to maintain loads at the
temperature at which they are loaded. Transport
refrigeration units are not designed to pull hot loads
down to temperature.
Post Loading Procedure
1. Make sure that all the doors are closed and locked.
2. Adjust the thermostat to the desired temperature set-
point.
3. Start the unit.
4. One-half hour after loading, defrost the unit by momen-
tarily pressing the Manual Defrost switch. If the coil
temperature has dropped below 42 F (5.6 C), the unit
will defrost. The defrost cycle should stop automati-
cally.
Weekly 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.
