4. Service and maintenance
4.1 Service
The system must be checked once every
month by the operator through observati-
on of the switching routine for operational
ability and leaks.
• Press flap closure button on control unit
• Allow water to flow in
• Wait until level-LED + pump trigger.
• Switch off water feed
• Switch off level-LED and wait for pump
• Re-open flap
Komfort: Please note that the backwater
valve must be open after the inspection
has been completed.
The pump should be checked at regular in-
tervals. If operational noises increase,
pumping capacity decreases or there are
vibrations in the pipeline system, the pump
housing and impeller must be checked for
any stubborn soiling or wear.
4.2 Maintenance (at least every six
months)
CAUTION: Disconnect the unit from the
mains during all servicing work! Heed
safety instructions! No warranty will be
granted in the event of insufficient
maintenance! All the servicing and
maintenance work described below
may only be carried out by authorised
qualified personnel. Repairs may only
be carried out by the manufacturer.
DIN 1986, part 3, must be heeded during
maintenance work on systems. Maintenan-
ce work must be carried out at least every
six months by authorised qualified staff.
The following tasks have to be carried out:
• Visual inspection of the complete system
• Thorough cleaning of the complete sy-
stem and the pump
• Check on the complete system and pump
housing for external damage and visible
wear
• Check on the pump for free movement,
wear and deposits
• Check the connection cables for mechani-
cal damage and wear
• Check the seal connections for leaks and
any recognisable wear
• Insulation test on the pump motor
• Check the control unit for damage and
soiling
• Check and clean the ventilation valve
• Clean the optical probe
We recommend these maintenance steps
after longer periods of standstill or interme-
diate storage, too, as well as after longer or
frequent occurrences of backwater. If pro-
blems should occur that cannot be elimina-
ted, please contact the specialist company
who carried out the installation (see stamp
on cover sheet) if in doubt.
