Monthly maintenance
Inspect intake opening for regeneration gas
The regeneration gas is fed to the system through an intake opening at the

Wait until the dryer has reached the stand-by phase (see page 21).

Work with care and do not touch hot surfaces:

After the vacuum pump has stopped, inspect screws at the intake
opening and retighten, if necessary.

Remove dirt from the screen covering the opening, using a suitable tool
(e.g. soft wire brush).
Note:
It is feasible to install an intake filter or to supply the regeneration air
to the dryer via an air duct if the ambient air is heavily soiled. Please
note the respective hints in sections
