Safety--3
CAUTION
Pre-trip inspection should not be per-
formed with critical temperature cargoes in
the container.
CAUTION
When Pre-Trip key is pressed, economy, de-
humidification and bulb mode will be deac-
tivated. At the completion of Pre-Trip activi-
ty, economy, dehumidification and bulb
mode must be reactivated.
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
To prevent trapping liquid refrigerant in the
manifold gauge set, be sure set is brought
to suction pressure before disconnecting.
CAUTION
The scroll compressor achieves low suc-
tion pressure very quickly. Do not use the
compressor to evacuate the system below
zero psig. Never operate the compressor
with the suction or discharge service valves
closed (frontseated). Internal damage will
result from operating the compressor in a
deep vacuum.
CAUTION
Use only Carrier Transicold approved
Polyol Ester Oil (POE) - EAL 32ST compres-
sor oil with R-134a. Buy in quantities of one
quart or smaller. When using this hygro-
scopic oil, immediately reseal. Do not leave
container of oil open or contamination will
occur.
CAUTION
Take necessary steps (place plywood over
coil or use sling on motor) to prevent motor
from falling into condenser coil.
CAUTION
DO NOT disassemble piston from NEW suc-
tion modulating valve powerhead assem-
bly. Doing so may result in damage to pis-
ton.
CAUTION
The unit must be OFF whenever a program-
ming card is inserted or removed from the
controller programming port.
CAUTION
Do not allow moisture to enter wire splice
area as this may affect the sensor resis-
tance.
CAUTION
Do not allow the recorder stylus to snap
back down. The stylus arm base is spring
loaded and damage may occur to the chart
or the stylus force may be altered.
CAUTION
The inside mechanism of the recorder,
particularly the inside of the element
housing, should never be oiled, however,
control mechanisms should be sprayed
periodically (every 60 days) with corrosion
inhibiting CRC 3-36a or 6-66 or LPS no. 2.
CAUTION
Recorder element capillary tubing may be
bent, but never sharper than 1/2” radius;
extra care should be taken when bending
adjacent to welds. The bulb should never
be bent, as this will affect calibration.
