8. SERVICING

It must be regularly checked the pump filter and clean if necessary. The service inter-
vals are based on the respective usage. We recommend a weekly control in much dirt
accumulation, if necessary daily inspection. Under normal pumping conditions the pump
requires no servicing.
With abrasive materials like sand the servicing duration can become shorter.
The following controls should be carried out regularly:
l Intactness of the electric cable
l Pre-pressure in the pressure tank (approx. 1.6 - 2.0 bar)
l Medium temperature max. 90°C
l That the connection hoses are not bent or broken
l Cleanness of the pump medium
Moreover, the pump should be emptied with risk of frost, be washed out with clear water
and stored dry.
