(I) Applicable to air-cooled models only.
(II) Applicable to compressors with enclosure.
NOTE
The required flow rate depends upon the
cooling water's temperature before it
enters the cooling system. The higher the
initial temperature, the higher the
required flow rate: the lower the initial
temperature, the lower the required flow
rate.

ENTING
Vent the system after installation, or after draining
the system at startup:
1. Open the water valve(s).
2. Open the vent cocks (located on top of the
aftercooler and lubricant cooler on the water
side) and let air escape from the system.
Close the vent cocks when water is visible at
their location - at this point the system has
been vented.

1. Disconnect both the inlets and discharge
water lines located at the rear of the com-
pressor.
2. Remove the drain plugs that are located at
the bottom of the aftercooler and the lubri-
cant cooler end caps.
3. Allow the system to drain completely.

UALITY
Water quality can significantly effect the efficiency of
the water cooling system. Dissolved minerals, gases,
and pH values are factors that contribute to the
formation of deposits and corrosion which can form
on the interior of cooling system pipes and heat
exchangers.
Scale can be a problem if the water supply has a
high concentration of calcium carbonate. It forms
lime scale deposits which act as thermal insulators
and restrict the water flow through the cooling
system. If scale is allowed to build up over time, it will
reduce the system's ability to remove heat and the
compressor can be damaged. Scale buildup can be
controlled with proper water treatment.
A thin lime scale coating is desirable and can inhibit
corrosion.
