F water temperature out of cooler. Maximum water flow shown is the maximum
allowable flow through aftercooler.
Saver
R
units on the same line, each unit is isolated by
the check valve in the unit discharge line.
If an Electra–Saver
R
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
R
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.
WATER PIPING (Water–Cooled Heat Exchanger
Models Only) – On machines equipped with water–
cooled heat exchangers, the water inlet and outlet con-
nections are located in the unit base flange on the left
side of the unit, when facing the control box.
It is mandatory that any water cooled
unit be installed in a shelter heated to
temperatures above freezing (32
_
F.,
0
_
C).
The water source should be capable of supplying up to
the maximum flow shown in FIGURE 2–7, page 13,
and FIGURE 2–8, page 14, at a minimum pressure of
40 PSIG; maximum allowable water pressure is 150
PSIG. The water flow rates shown in FIGURE 2–7,
page 13, are approximate and a guide to sizing piping,
cooling tower and other water system equipment.
