SPECIFIC WARNING AND CAUTION STATEMENTS - - Continued
CAUTION
When Pre-Trip key is pressed, dehumidifi-
cation and bulb mode will be deactivated.
At the completion of Pre-Trip activity, dehu-
midification and bulb mode must be reacti-
vated.
CAUTION
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.
CAUTION
When a failure occurs during automatic
testing the unit will suspend operation
awaiting operator intervention.
CAUTION
When Pre- -Trip test Auto 2 runs to comple-
tion 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!
CAUTION
The unit will remain in the full cooling mode
as long as the emergency bypass switch is
in the BYPASS position. If the cargo may be
damaged by low temperatures, the operator
must monitor container temperature and
manually cycle operation as required to
maintain temperature within required lim-
its.
CAUTION
The unit will remain in the DEFROST mode
as long as the emergency defrost switch is
in the DEFROST position. To prevent cargo
damage, the operator must monitor con-
tainer temperature and manually cycle op-
eration 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 stator 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 pre-
cautions to avoid bending or breaking it
while changing crankcase positions.
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 com-
pressor 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 contamina-
tion will occur.
Take necessary steps (place plywood over
coil or use sling on motor) to prevent motor
from falling into condenser coil.
