used, the line must be shot blasted and cleaned to
remove welding scale. In either case, the inlet line
must be coated internally by galvanizing or painting
with a moisture and oil–proof sealing lacquer. Up to ten
(10) feet (3 meters) in length, the inlet line should be the
full size of the inlet opening on the compressor. If an
extra–long line is necessary, the pipe size should be in-
creased according to Inlet Line Length Chart

Accessibility for inlet air filter servicing must be consid-
ered when relocating the filters from the unit to a remote
location.
DISCHARGE SERVICE LINE – The discharge service
line connection on both water–cooled and air–cooled
units is made from the left side at base level from the
motor end of the package. When manifolding two or
more rotary screw units on the same line, each unit is
