WARNING
The use of make-up water exceeding the quality units outlined in the “RO Water
filter”, Section 8, may result in damage to critical compressor components by
corrosion and/or scaling action of impurities in the water.
NOTICE
Water may no longer be potable after use in the compressor.
AUXILIARY AIR RECEIVER - An auxiliary air receiver is not required if the piping system is large and
provides sufficient storage capacity to prevent rapid cycling. When used, an air receiver should be of
adequate size, provided with a relief valve of proper setting, a pressure gauge and a means of draining
condensate. A system with adequate volume would produce consecutive compressor unload cycles of
no less than 30 seconds.
MOISTURE SEPARATOR/ORIFICE - Since the unit is equipped with a built-in aftercooler, an integral
moisture separator and drain trap is furnished with the unit. The moisture from the trap is piped to the
compressor inlet flange.
INLET LINE - Where an inlet line is used between the air filter and the compressor, it must be
thoroughly cleaned on the inside to prevent dirt or scale from entering 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 moisture and oil-proof
sealing lacquer. Up to ten (10) feet in length, 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” chart, Figure 2-3, page 8.
Accessibility for inlet air filter servicing must be considered when relocating the filters from the unit to a
remote location.
Length of Inlet Line Diameter of Pipe Size
0 to 10 Feet (0 to 3 Meters).............................. Same as Compressor Inlet Opening
10 to 17 Feet (3 to 5 Meters).............................. One size Larger Than Inlet Opening
17 to 38 Feet (5 to 11.5 Meters) ......................... Two Sizes Larger Than Inlet Opening
