Maintenance

CAUTION
Electronics repairs must only be performed by trained electricians, following the safety regulations
of the professional association VB G 4 and ZH 1/11)!
CAUTION
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.
NOTE
The following inspections are recommended:
 suction pipes and pressure pipes for leak-free connections
 suction valve and pressure valve (chapter
and metering cartridges"), for dirt and tightness.
 discharge connection (chapter
 correct metering
 metering head screws (chapter
Fig. 11.3, Pos. 1) (stable seat, 3 - 4 Nm)

Prior to repair and maintenance work and metering of dangerous media, always rinse the
metering head, relieve the pressure pipe and wear protective clothing (protective goggles,
gloves and apron).
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.
The maintenance interval is half-yearly. Shorter intervals are recommended in the event of
heavy loads (e.g. continuous use).

The life of the diaphragm depends on the backpressure, operating temperature and
metering medium.It is recommended to inspect the diaphragm more frequently in extreme
operating conditions or if abrasive substances are metered.
