The non-return valve is maintenance free, but is subject to wear
like any other moving part. We recommend a visual inspection
every 3 months. In this connection, the non-return valve must be
dismantled, cleaned, freed of deposits and checked for freedom of
motion.
Safety valve inspection The safety valve is no regulating device!
The operational capability must be checked on start-up and
later at weekly intervals.
The safety valve must be secured against misadjustment. Blocking
or manipulating the safety valve can have penal consequences if it
gives rise to an accident. Any warranty claims shall also be
forfeited in such a case.
The nominal opening pressure may not exceed the maximum
permissible final overpressure (refer to Tab. 2) or the permissible
system pressure, provided the latter is lower.
Functional testing is carried out by actuating the manual ventilation

7 Maintenance
7.1 Safety during maintenance work
See chapter 2.6 "Occupational safety and special risks".
Personal protective equipment
The following must be worn during all maintenance work:
The following describes the maintenance work that is necessary for
an optimum, trouble-free operation. Maintenance intervals must be
observed.
If increased wear of individual components or functional groups is
determined during regular inspections, the operator has to reduce
the required maintenance intervals on the basis of the actual signs
of wear.
Changes compared to normal operation (increased power
consumption, temperatures, vibrations, noises, etc. or response of
monitoring systems) lead to the assumption that the functions are
impaired. These then have to be subjected to an inspection by
specialised staff.
In case of queries regarding the maintenance work and intervals:
contact the manufacturer (service address page 2).
This chapter describes possible causes of malfunctions and
troubleshooting tasks.
Reduce the maintenance intervals if similar malfunctions occur
repeatedly due to above-aver age intens i ve use so inter va ls
correspond to the actual load.
Contact the manufacturer in case of malfunctions that cannot be
repaired with the aid of the following information ( p. 2)!
See chapter 2.6 "Occupational safety and special risks".
The trouble shooting work described at this point can be carried
out by the operator, unless otherwise indicated.
Some work may only be carried out by specially trained
specialised staff or exclusively by the manufacturer himself.
This is specifically pointed out in the description of the individual
malfunctions.
Only electrical specialists may carry out work on the electrical
system.
Components and parts may only be replaced by specialised
staff.
See chapter 2.5.
