4. Maintenance and service
In normal use, the break tank requires little maintenance. A few points of interest:
• After being installed or drained, the delivery pump must be vented. To do this, remove the drain
plug from the filler opening at the top of the pump housing. After the pump housing has been
completely filled, the pump can be switched on. Never let the pump run dry!
• Make sure that the feed pump always works with a minimum back pressure of 1 bar. This is to
keep the pump running in its Q / H curve and to prevent damage to seal and impeller.
• The float switch is in a R.V.S. basket built. This is to prevent faults from pollution. However,
grease deposits and small dirt particles can still affect the operation of the float switch
(especially when mounting in a skimmer, for example). From time to time the float should
therefore be inspected.
• Spare parts are always available at SEM Water Treatment.
• The operating hours of the pump can be read in the service menu.
