CONTROL PIPING – Control piping is not necessary
since the Electra–Screw
R
unit is factory wired and
piped for the control system specified.
INLET LINE – Where an inlet line is used between the
air filter and the compressor, it must be thoroughly
cleaned on the inside to prevent dirt or scale from enter-
ing the compressor. If welded construction is 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 mois-
ture 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 increased according
to Inlet Line Length Chart, FIGURE 2–4.
