3-6 Loading Procedure Operating Instructions
CSR-20 & CSR-40, September 1999
Loading Procedure
1. Make sure the Unit On/Off switch is OFF before opening
the container doors. (The unit may be operating when
loading the container from a warehouse with door seals.)
2. Spot check and record load temperature while loading.
Especially note any off-temperature product.
Post Load Procedure
1. Make sure all doors are closed and locked.
2. Start unit if unit is OFF.
3. Check controller setpoint for proper setting.
4. If trip ID information has NOT been entered in the con-
troller, enter it now using the PC-PAC™ software (see
instructions of PC-PAC™ software).
5. One-half hour after loading, initiate a manual defrost
cycle:
• Press the DEFROST key. The display flashes “ENTER
DFRST”.
• Press the ENTER key. “LOAD DFRST” briefly appears
in the display. The Defrost LED turns ON as the unit
enters Defrost. The controller then returns to the
Standard Display. Defrost will stop automatically.
NOTE: The evaporator coil temperature must be
below 10 C (50 F) to allow the unit to enter a
defrost cycle. If the evaporator coil temperature
is too high, the controller display will show
“DFRST INVAL” (defrost invalid) for 3 seconds.
The controller then returns to the Standard
Display.
