Shutdown and restart dryer
In the following cases, the dryer must be fully shut down and depressurised:
In the event of an emergency or malfunction
For maintenance work
For dismantling
Risk of injury from escaping compressed air!
Never remove any parts of the dryer, or manipulate the same in any way,
as long as the unit is pressurised! Suddenly escaping compressed air
might cause serious injuries.
Prior to any work, release all pressure from the unit.
Caution!
Risk of damage to the dryer, if it is switched off during the expansion or
drying phase.
During these phases, the pressure in the regenerating chamber is
released to ambient pressure: If the main valve is opened, as the dryer is
switched off, there is a sudden pressure build-up in the chamber. This
might result in
damage to the drying agent, and
excessive abrasion, with negative impact on the regeneration capacity.
Before switching off the dryer, wait until it has reached the pressure build-
up phase or is in standby mode (before switchover).
Note:
If the unit is equipped with a compressor synchronisation system,
first switch off the compressor and then wait until the dryer has
reached the standby phase before switching it off with the ON/OFF
switch.
This ensures that the regeneration cycle is completed, and that the
pressure in both chambers is at the same level.
Note:
As soon as the dryer is switched on again, the programme continues
the cycle from the point at which it has been stopped.
