Safety-3
CAUTION
Pre-trip inspection should not be performed with critical temperature cargoes in the container.
CAUTION
When Pre-Trip key is pressed, economy, dehumidification and bulb mode will be deactivated. At the
completion of Pre-Trip activity, 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 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!
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 suction 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) -- Castrol-Icematic SW20 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.
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 suction modulating valve powerhead assembly. Doing so
may result in damage to piston.
CAUTION
The unit must be OFF whenever a programming card is inserted or removed from the controller pro-
gramming port.
CAUTION
Do not allow moisture to enter wire splice area as this may affect the sensor resistance.
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.
