Maintenance work to be completed every 48 months
To complete the following maintenance tasks, you must dismantle the pipe
bridges and the vessels. We therefore recommend that you carry out these tasks
together.
Note:
In accordance with national regulations, a pressure vessel inspection
may be prescribed to be carried out at regular intervals by an
independent supervisory office.
For an inspection of the pressure vessels, the drying agent must be
removed as described as follows.
When inspecting the pressure vessels, it is recommended to check
the condition of all fittings such as e.g. sieve bottoms and dust
sieves, including gaskets. If necessary, these fittings must be cleaned
or renewed.
In the event of comprehensive maintenance or repair tasks, contact
the manufacturer (see page 6).
Replace dust sieve
Between vessel and upper arch pipe, dust sieves are fitted which retain the
drying agent dust. If these dust sieves become blocked, a dam pressure is
generated which can cause compressed air fluctuations in the compressed air
system.
For disassembling the dust sieves, the entire arch pipe must be removed first.
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 upper arch
pipe.

Depressurise dryer and take out of service (see page 39).
