Water in system
Compressed Air Inlet and
outlet connections are
reversed. Check inlet and outlet connec-
tions. This dryer is designed for air flow
in one direction only. Inlet and
outlet directions are identified on
the dryer.
Drain system is clogged
or inoperative. Restore a free flow
of water condensate.
Check water
evacuation. Drain system is timed solenoid
valve, pneumatically assisted
which has to be adjusted in
accordance with values listed in
this manual.
The Solenoid valve includes a
strainer that has to be periodically
checked and cleaned. Mem-
branes of pneumatically assisted
drain have to be checked or
replaced every 6 months.
Bypass system is open Check the valves Important : Bypass piping should
be installed around the dryer so
the dryer can be isolated for ser-
vice without shutting down the air
supply. During dryer operation,
valves must be set so all air goes
into the system. Check tightness
of the bypass system.
Free moisture remains in
pipe lines. Blow out the system Before the dryer is first started all
free moisture should be blown
out of the system.
Excessive air flow Check actual flow
through the dryer. This dryer is designed for a maxi-
mum air flow. If too much air is
pumped into the dryer, water
removal capacity may not be suf-
ficient, resulting in liquid Carry-
over downstream. Check the
rated flow of the air compressor.
