7 Maintenance and repair
Under normal use, the pressure switch ZP SPEEDCONTROL COMFORT requires only a
minimum of maintenance. We recommend that the plant operating company carries out a
monthly visual inspection.
The proper functionality and quiet performance of the pump should be inspected regularly.
This can help prevent bigger disruptions.
Dry-running of the pump should be avoided, because the lubricating ring seal cools down
with the liquid. The motor is maintenance-free. Empty the pump if there is a risk of freezing
through the drain plugs.
During the cold season and with a longer standstill of the plant, the pump body and the
control should be emptied. If the plant is not used at all for a longer period of time, the
pump and control must be cleaned and stored in a dry, well-ventilated area.
Inspection:
Examine the pressure, impermeability, pump and fl ow noises as well
as functionality. If defects are determined, contact your contract
partner/merchant.
