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 8).
