SPECIFIC WARNING AND CAUTION STATEMENTS - - Continued
Pre-trip inspection should not be performed with critical temperature cargoes in the container.
When Pre-Trip key is pressed, dehumidification and bulb mode will be deactivated. At the comple-
tion of Pre-Trip activity, dehumidification and bulb mode must be reactivated.
When condenser water flow is below 11 lpm (3 gpm) or when water-cooled operation is not in use, the
CFS switch MUST be set to position "1" or the unit will not operate properly.
When a failure occurs during automatic testing the unit will suspend operation awaiting operator
intervention.
When Pre- -Trip test Auto 2 runs to completion without being interrupted, the unit will terminate pre-
trip and display "Auto 2" "end." The unit will suspend operation until the user depresses the ENTER
key!
The unit will remain in the full cooling mode as long as the emergency bypass switch is in the BY-
PASS position. If the cargo may be damaged by low temperatures, the operator must monitor con-
tainer temperature and manually cycle operation as required to maintain temperature within required
limits.
The unit will remain in the DEFROST mode as long as the emergency defrost switch is in the DE-
FROST position. To prevent cargo damage, the operator must monitor container temperature and
manually cycle operation as required to maintain temperature within required limits.
To prevent trapping liquid refrigerant in the manifold gauge set be sure set is brought to suction
pressure before disconnecting.
Removing the compressor motor press-fit stator in the field is not recommended. The rotor and sta-
tor are a matched pair and should not be separated.
The copper tube which connects to the oil suction strainer extends out the bottom with the bottom
plate removed. Take precautions to avoid bending or breaking it while changing crankcase posi-
tions.
Ensure that thrust washer does not fall off dowel pins while installing oil pump.
The set screw on the crankshaft must be removed for this type of oil pump.
Use only Carrier Transicold approved Polyol Ester Oil (POE) - - Mobil ST32 compressor oil with
R-134a. Buy in quantities of one quart or smaller. When using this hygroscopic oil, immediately
reseal. Do not leave container of oil open or contamination will occur.
