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. 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 2–6, page 12.
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 water–cooled units with aftercooler
is made at the moisture separator. On air–cooled units
and water–cooled without aftercooler, the connection
is made at the pipe nipple located behind the instru-
ment panel. When manifolding two or more
Electra–Saver units on the same line, each unit is iso-
lated by the check valve in the unit discharge line.
If an Electra–Saver unit is manifolded to another com-
pressor, be sure the other compressor has a check
valve in the line between the machine and the manifold.
If an Electra–Saver and a reciprocating compressor
are manifolded together, an air receiver must be lo-
cated between the two units.
Discharge air used for breathing will
cause severe injury or death.
Consult filtration specialists for
additional filtration and treatment
equipment to meet health and safety
standards.
