regulations of the professional association VB G 4 and ZH 1/11)!
CAUTION!
When opening the covers or removing parts, except when this is possible
without tools, voltage-carrying parts may be exposed. Connection points may
also be under live voltages.
Before calibration, maintenance, repairs or replacement of parts, the device must be
disconnected from all voltage sources if it is necessary to open up the device.
NOTICE!
The maintenance interval is half-yearly. Shorter intervals are recommended in
the event of heavy loads (e.g. continuous use).
The following inspections are recommended:
1.
Suction pipes and pressure pipes for leak-free connections.
2.
Suction valve and pressure valve (
Chapter 11.1 ‘Austausch von Saug- / Rücklauf-
, Fig. 86) for dirt and impermeability.
3.
Discharge connection (Fig. 3) on pump head (for diaphragm breakage).
4.
Correct metering.
