2.8 INTEGRAL DRYER OPTION
An integral refrigerated dryer option is available. The
integral dryer is designed to work with the
compressor WS controller which controls dryer
starting and stopping, condensate drain valve
function and monitors dewpoint temperature and
dryer warnings and faults. The dryer is fully
connected from the factory and is ready to run when
the compressor is installed.
Detail of dryer operation and spare parts can be
found in a supplement Manual 02250174-308 which
is provided with your machine.
Per the controller default settings, on initial start-up
the compressor will run unloaded for 5 minutes,
allowing the dryer to run and cool down. This
prevents condensate from initially being allowed into
the compressed air stream. It also delays the supply
of compressed air from the compressor until the 5
minute cool-down period is completed. When the
automatic control mode is selected, the compressor
will stop after running unloaded for a prescribed time,
but the dryer will continue to run to ensure there will
not be a surge of condensate when the compressor
re-starts. For other settings and control options, refer
to the WS controller manual 02250164-411, or to
your authorized Sullair servicing distributor.
In case the compressor needs to operate while the
dryer is being serviced, the dryer can be bypassed,
and removed if necessary for service. To bypass the
dryer, disconnect the inlet hose to the dryer,
disconnect the outlet hose at the main service
connection, and re-connect the dryer inlet hose to the
main service connection. Remove the fuses
powering the dryer located in the compressor
electrical box. The WS controller must be set-up for
the compressor to run on dryer fault. If necessary,
this can be reset by your authorized Sullair servicing
distributor.
