10. Servicing the product 10.1 Maintaining the product
During normal application and operation, the SLC, DLC pump
control panels are maintenance-free.
However, it is advisable to carry out minor checks of the SLC or
DLC pump control panel, pump pits, tanks, pumps, etc. at suitable
intervals.
These checks should be carried out by authorized personnel.
• Check the gaskets of the SLC or DLC control panel cabinet
front and those of the Pg cable entries.
• Check the cable entries for the explosion hazard area.
• Check for possible deposits/sludge build-up in the pump pit/
tank. Sludge may settle in areas with almost stagnant liquid.
• Check for beginning sludge build-up around the float switches,
or on the float switch.
• Check for possible blockage on the suction side of the pump.
• A blockage will typically be a large solid object.
• If the SLC or DLC control panel has been installed in a
particularly aggressive environment, check the motor
protection contacts for corrosion. In typical installations, the
motor protection contacts will work for several years and do
not require any inspection.
