Loading and Enroute Inspections
This chapter describes pre-loading, post loading, and enroute
inspection procedures. 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.
Pre-Loading Inspection
1. Check the engine oil pressure indicates OK. When first
starting a cold engine, the oil pressure may be higher.
2. Pre-cool products before loading. Note any variances on
the manifest.
3. Inspect door seals and vent doors for condition and a tight
seal with no air leakage.
4. Inspect the truck inside and out. Look for:
• Damaged or loose truck skin and insulation
• Damaged walls, air ducts, floor channels or “T”
flooring
• Clogged defrost drain tubes
• Blocked return air bulkhead
5. Verify that the setpoint temperature is correct for your
cargo. Pre-cool the truck as required.
6. 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 truck 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 truck.
