and placed so that damage will not occur in normal
maintenance or traffic past the unit.
If the leak develops through the packing, tighten the
packing gland nut firmly with a wrench to reseat the
packing around the valve stem, then back off the nut
until loose, and finally retighten the nut finger tight.
Tightening the packing nut too tight may cause erratic
operation. An occasional drop of oil on the valve stem
at the packing nut will prolong packing life.
If valve malfunctions, check for bent or binding, paint
or corrosion on valve stem, foreign material in valve,
erosion, or thermal system (capillary) failure. If foreign
material or scale is likely, the use of a strainer in the in-
let water line is recommended.
WATER SHUTOFF VALVE – WATER–COOLED
HEAT EXCHANGER (Optional Equipment)
(FIGURE 5–1, page 31) – A magnetic solenoid–oper-
ated water shutoff valve rated at 150 psig (10.3 Bars)
water pressure should be mounted in the water outlet
line after the oil cooler. The valve should be wired into
the compressor control circuit so that the valve opens
to allow water to flow any time the compressor is run-
ning. When compressor stops under automatic con-
trol, or is shut off manually, the valve should close, stop-
ping water flow through the system. See Wiring
Diagram, page 29.
Compressor, air/oil reservoir, separa-
tion chamber and all piping and tub-
ing may be at high temperature during
and after operation.

OIL RESERVOIR – The oil reservoir–separator com-
bines multiple functions into one vessel. The lower half
is the oil reservoir, providing oil storage capacity for the
system and the top portion, a primary oil separation
means. The reservoir also provides limited air storage
for control and gauge actuation.
