Correctly affi xing the top plate
Replace demisters, perforated plates and drying agent
To complete the following maintenance tasks, you must dismantle the plates and the vessels.
We therefore recommend that you carry out these tasks together.
Replace upper perforated plates
Perforated plates designed to retain the drying and purifying agents are fi tted under the
check valve plate and above the solenoid valve plate. If these perforated plates become
blocked, a dam pressure is generated which can cause compressed air fl uctuations in the
compressed air system.
In order to remove the upper perforated plates, the check valve plate must be removed.
Risk of falls!
The dryer must not be misused as a climbing aid! The components have not
been designed for such loads and could fracture.
Only use approved climbing aids when disassembling the check valve plate.
Depressurise the dryer and shut it down
(see page 30).
Loosen the screws at the top plate and lift
off the plate.
Removing and replacing perforated plates
