IZING
Pipes should be sized as a minimum to match the
connection. All piping and fittings should be rated for
the discharge pressure.
4.4 AUXILIARY RECEIVER TANK
An Auxiliary receiver tank should be installed in
systems where large demand fluctuations will occur.

ALVES
Install isolation valves where isolation of the
compressor from the service lines is required. These
valves should have drip legs that drain at an angle
downward from the base. A vent to the piping should
be installed downstream of the compressor outlet
connection.
When two compressors are installed to operate in
parallel with a common receiver tank, an isolation
valve and drain trap for each compressor should be
installed before the common receiver.
Compressors have built-in aftercoolers and are
equipped with a condensate drain located next to the
air outlet connection. A drain line should be installed
to remove the condensate, which builds up during
compressor operation.
4.5 COUPLING ALIGNMENT
CHECK
No coupling alignment check is required.
4.6 FLUID LEVEL CHECK
The compressor is shipped fully charged with the
proper amount of fluid. However, it is necessary to
check the fluid level at the time of installation and
during compressor operation. Check the fluid level
when the compressor is in the SHUT DOWN MODE
(fluid level may not be visible when operating), and
by looking at the sight glass on the receiver tank
(See
Figure 3-1 ). The full level is at half the sight
glass. Add fluid if fluid level is not visible in the sight
glass when machine is shut down.
NOTE
Compressors not equipped with an auxiliary
receiver tank may need to have their
response times adjusted. Contact Sullair
Customer Care for assistance.
