Remedy
Check separator differential.
Clean and service strainer located in
the line off the bottom of the water sep-
arator.
Remove the water vapor from com-
pressed air prior to distribution through
the air system. 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 car-
tridges as recommended by the filter
manufacturer). Check all drain traps
routinely to insure their proper opera-
tion. Maintain them regularly.
Ensure valve opens and closes as sig-
naled by timer.
Check drain interval and drain time,
and adjust accordingly. High humidity
conditions require longer drain times or
more frequent openings.
