Plugged Strainer in Moisture Drain
Line
Clean and service strainer located in the
line off the bottom of the water separator.
Water Vapor Condensation From
Cooling And Compression Occurs
Naturally
Remove the water vapor from compressed
air prior to distribution through the air sys-
tem. Check operation of aftercooler and
moisture separator. Install a compressed air
dryer sized for the flow and dryness level
required. (Note: Filters may also be
required to remove particulates, liquid oil
aerosols or for oil vapor removal. Change
cartridges as recommended by the filter
manufacturer). Check all drain traps rou-
tinely to insure their proper operation. Main-
tain them regularly.
Defective Drain Solenoid Valve Ensure valve opens and closes as signaled
by the WS Controller.
Inadequate Drain Timer Settings Check WS Controller control drain interval
and drain time, and adjust accordingly. High
humidity conditions require longer drain
times or more frequent openings.
