High pressure drop
Excessive compressed
air flow or too low air inlet
pressure.
Check actual
pressure and flow
through the dryer.
This dryer is designed for a
maximum air flow. If too much
air is pumped into the dryer,
water removal capacity may
not be sufficient, resulting in
liquid carry-over downstream.
Check the rated flow of the
air compressor.
Freeze up
Check that compressor room
ambient is above 41°F.
Frosting of the lines is an indica-
tion that controls are set too low.
The following should be done by
an experienced refrigeration
technician.
Fan switch could have failed
in closed position keeping fan
on.
Controls may be adjusted in the
fields by means of the hot gas
bypass valve.
Turn screw clockwise to increase
refrigerant pressure setting which
will increase pressure dew point.
Turn screw in 1/2 turn increments
until frost disappears. Allow 15
minutes for pressure stabilization
with air flowing.
Clogged heat exchanger
Clean heat exchanger
with a reverse air flow.
Dryer are supposed to be used
with compressed air free of any
aggressive contaminants. Some
contamination may require extra
maintenance of the heat
exchanger. Contact your Sullair
Distributor.
The unit will not run or
cycles off and on.
Line disconnect switch is
open.
Close the start or disconnect
switch.
If the dryer is not operating,
check the disconnect switch or
circuit breaker to be certain it is
on.
Fuse or breaker is open
Replace fuse or reset breaker. The fuse to the power line should
be checked and replaced if
needed. Never replace a burnt
fuse with an oversized fuse.
Faulty refrigerant
compressor or controls.
Determine the cause
and make correction
Failure of compressor to run may
be caused by several factors. A
qualified refrigeration specialist
should check all electrical and
refrigeration controls, or factory
should be contacted if unit is in
warranty.
