Note: this type of dryer operates best if left on whenever possible with air
supplied to the unit.
The unit can be left pressurized after the dryer is switched off.
If the dryer needs to be turned off and depressurized, do the
following:
1. Slowly OPEN the by-pass valve.
2. Slowly CLOSE the Inlet and outlet "shut- off” valves.
3. Slowly open the purge exhaust valves and the dryer system starts to
depressurize. Switch off electrical power after both towers have been
depressurized.(The Dryer can also be depressurized through the valve
on the After Filter drain and through the Inlet Filter drain.)
