Electric current warning!
Work on the electric system must only be carried out by qualifi ed technical
personnel!
Cleaning
Remove dust with dry cloth; use moist cloth, if necessary.
Clean all surfaces, e.g. at the operating panel, with a moist cloth.
Daily maintenance tasks
Complete visual inspection and function test of the entire dryer
Inspect dryer for visual damage and unusual noises.
If your dryer is not connected to an alarm system (see page 28), check whether there
is an error message on the display at the electrical panel. Assess any existing fault messages
(heed the malfunction table in the controller manual!).
Check whether compressed air has reached the set pressure dewpoint.
Check dam pressure
If, following depressurisation of a vessel, e.g. after the expansion phase, the overpressure
has not decreased to < 0,5 bar, then there is a residual pressure, designated as dam pres-
sure, in the vessel.
Check for dam pressure: if the dryer functions correctly, the respective pressure gauge
indicates < 0,5 bar. Then there is no dam pressure.
If the dam pressure is greater than < 0,5 bar:
Depressurise the dryer and shut it down (see page „Depressurising and shutting down the
dryer“ 37).
Dam pressure can be caused by:
◊ a blocked muf er,
◊ a malfunction of the expansion valve,
◊ a leaking pressure build-up valve.
The respective necessary maintenance measures are described in the following sections.
Monthly maintenance
Inspect intake opening for regeneration air
The regeneration air is fed to the system through an intake opening at the heater.
Wait until the dryer has reached the stand-by phase (see page „Stand-by-phase (for
dewpoint measurement option)“ 17).
Work with care and do not touch hot surfaces:
— ...After the vacuum pump has stopped, inspect screws at the intake opening and retigh-
ten, 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 fi lter or to supply the regeneration air to the
dryer via an air duct if the ambient air is heavily soiled. Please note the respec-
tive hints in sections Options.
