To decrease water flow (e.g., increase exiting cooling water temperature) turn the adjusting screw
from left to right, increasing spring tension. (The groove at the lower edge of the adjusting screw is
an index line for use with the index scale 0 to 8 in obtaining a desired setting).

Care must be used when handling the capillary tube; a kink or break in the tubing or connections will
make the valve inoperative. Never attempt to change capillary length. Excess capillary tube should be
carefully coiled and placed so that damage will not occur with normal maintenance or traffic past the unit.
If a leak develops through the packing, tighten the packing gland nut firmly with a wrench to reseat the
packing around the valve stem, 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 the valve malfunctions, check for a bend or binding in the capillary tube, paint or corrosion on valve
stem, foreign material in valve, erosion or thermal system (capillary) failure.
WATER FLOW SHUTOFF VALVE -
This device completely shuts off the flow of cooling water when the
compressors are not operating. Its normally closed state prevents the waste of cooling water even in the
case of power failure. It is a common companion to the water flow regulating valve.
The water flow regulating valve and the water shutoff valve are factory-installed options. If the presence
of foreign material or scale formation in the cooling water is likely, the use of a strainer in the inlet water
line is recommended.
WATER SEPARATOR AND DRAIN
– These devices separate and drain the water (condensed by the air
cooler) mixed with the compressed air delivered by the compressor package. Note that if this device is
not used, the optional compressed air dryer is supplied; as the latter
’s water separator is employed for
this process.
