Figure M-MP-10. Typical water-cooled (SXWF) compressor section components
To charge the system, complete the
following procedure:
1. Charge liquid refrigerant into the liquid
line service valve of each compressor
circuit. The vacuum will draw some of
the required refrigerant into the
system. See Figure O-M-9.
2. Complete the charging process by
charging gaseous refrigerant into the
suction line shrader valve with the unit
running. However, make sure that
some refrigerant is present in each
circuit before starting the compressors.
The refrigerant container should be
upright so that gaseous refrigerant is
drawn off the top.
Note: See Tables M-MP-6 and M-MP-7 for
refrigerant charge requirements.
NOTICE
Compressor Damage!
Do not allow liquid refrigerant to enter
the suction line. Excessive liquid accumu-
lation in the liquid lines may result in
compressor damage.
