blocked up.
Compressor relay / contac-
tor stuck.
Microprocessor Control relay
bad.
Probe not completely in
thermal well.
Problem persists.
Inlet / outlet pipe internal
diameter too small causing
air-lock or back pressure.
Excessive use of bends /
elbows in inlet / outlet pipe
work causing air-lock/ back
pressure.
Outlet pipe too long / too
high causing back pressure.
More than one condensate
source connected providing
alternative path for conden-
sate.
Debris trapped under seal.
Damage to seal.
Open valves.
Change filter elements.
Replace relay / contactor.
Replace relay.
Inspect probe and check
readings against independ-
ent source (eg. temperature
analyzer/pyrometer/ice
bath) both in exchanger well
and to ambient.
Turn dryer off and consult
your local
distributor for further assist-
ance.
Check installation is in ac-
cordance with this manual.
Revise installation accord-
ingly.
Replace with larger diam-
eter piping.
Reduce the amount of
bends and elbows.
Reconfigure condensate
piping.
Reroute condensate to elim-
inate secondary path. Install
check valves as required.
Check power supply. Press
test button for minimum 2
seconds and observe. Locate
and eliminate supply fault.
Press and hold the test
button to clear (drain valve
will open). Replace seal with
Service Kit.
If bottom inlet is used, top
port must be used as air
bleed. Make sure Connect
the top inlet to a higher
point in system, which will
function as an air bleed for
the drain.
