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
offi ce.
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 conditi-
on of all fi ttings such as e.g. sieve bottoms and dust sieves, including gaskets.
If necessary, these fi ttings must be cleaned or renewed.
In the event of comprehensive maintenance or repair tasks, contact the manu-
facturer (see page 8).
Replace desiccant sieve
Between vessel and upper arch pipe, desiccant sieves are fi tted which retain the drying agent
dust. If these desiccant sieves become blocked, a dam pressure is generated which can
cause compressed air fl uctuations in the compressed air system.
For disassembling the desiccant sieves, the entire arch pipe must be removed fi rst.
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.
