6 MAINTENANCE AND SERVICE
Safety instructions
WARNING! Risk of injury!
Improper use of the material pressure regulator carries the risk of serious personal injury and serious
damage. Therefore, maintenance and cleaning work must only be carried out by qualified personnel or
personnel specially trained for these tasks (training to be documented)!
Carry out maintenance and cleaning work on the material pressure regulator only when the regulator
and the system are pressureless!
WARNING! Danger of burns!
Allow the device to cool down before carrying out any work on the material pressure regulator!
6.1 General and safety instructions for maintenance and service
Cleaning
The material pressure regulator needs to be cleaned if
> is dirty from use
> a different material must be used
> parts subject to wear must be replaced.
IMPORTANT!
Do not use sharp-edged metal tools for external cleaning; use only soft brushes.
!
Solvents or halogenated cleaners can cause chemical reactions when used on aluminum and galvanized
components. This can lead to explosive and chemical reactions! Therefore, only cleaners may be used that
do not contain the ingredients mentioned above.
Maintenance
The material pressure regulator must be serviced/checked regularly, as the seals begin to wear out after a certain time
and are subject to natural wear. Defective seals can be identified by the fact that air or fluid escapes from the connection
points where the seals are mounted.
Make sure that the gasket material used is compatible with the fluid used.
Before starting any maintenance work:
> Wear personal protective equipment.
> Depressurise the material pressure regulator.
> Disconnect the lines.
NOTE!
The material pressure regulator should be checked regularly for wear. It is not possible to
concretely predict when wear will occur, since this depends on the material being processed and
the conditions of use.
