WARNING
Relieve internal pressure of replacement
compressor by slightly loosening the bolts
of both service valve flanges/blank valve
pads and then lightly tapping the center of
the valve flanges/pads with a soft mallet to
break the seal.
WARNING
Do not use a nitrogen cylinder without a
pressure regulator. Cylinder pressure is
approximately 159.9 Bars (2350 PSIG). Do
not use oxygen in or near a refrigerant sys-
tem as an explosion may occur. (See
Figure 8 --32)
WARNING
The Compressor Discharge Pressure
T ransducer does not have a Schrader valve
in the connecting fitting. Any discharge
pressure remaining in the compressor will
be released when removing the CDP.
WARNING
Carrier Transicold does not recommend al-
lowing the compressor to pull less than 0
Bar/PSIG at any time.
CAUTION
Service Mode MUST be used whenever re-
moving refrigerant charge, refrigerant leak
checking or evacuating.

ol Ester Oil (POE). Buy quantities of one
quart or less. When using this hygroscopic
oil, immediately reseal. Do not leave con-
tainer of oil open or contamination will oc -
cur .
