4. Re-calibrating and servicing

GB
We recommend having the system re-calibrated by the manufacturer at regular
intervals of approx. 12 months. Every re-calibration at the factory also includes a
comprehensive and free checking of all system parameters.
During the first re-calibration a service file is started automatically in which every
re-calibration and all extra services are recorded.
The instrument requires almost no maintenance, because all parts which are mo-
veable are extremely robust. There are no parts which have to be serviced by the
user. During each re-calibration the functioning of all components is checked and
changed if necessary.
To clean the membrane keypad and the display, use only customary plastic or
glass cleaning agents in compliance with the guidelines of the manufacturer. Use
cloths which are not prone to generate fluffs.
Before cleaning the surface of the instrument, it has to be made
sure that it is not pressurised, the power is switched off and the
power supply is disconnected.

5. Dismantling of the system

Work on electrical or pneumatic/hydraulic equipment must only
be carried out by qualified and authorised technical staff, obser-
ving the corresponding safety regulations.
When dismantling the system please proceed as follows:
1. Make sure that there is no positive or negative overpressure on the system and
that all parts of the appliance are at room temperature.
2. Switch off the system from the main switch ON/OFF at the front and rear side.
3. First pull out the mains cable from the mains socket and then from the power
supply input socket of the system.
4. Disconnect the pressure connections.
5. Make sure that the system is free of any medium.
