When Guideline
Before storage
• The pump must be allowed to run for a short time after raising it to
discharge remaining pumped liquid.
• The discharge opening must be covered in a suitable way, or placed
facing down so that any still remaining pumped liquid runs out.
• If present, the cooling jacket must be drained manually by opening the
air vent screws at the top of the cooling jacket.
After storage If the impeller/propeller is frozen, it must be thawed by immersing the pump
in liquid before operating the pump.
NOTICE:
Never use a naked flame to thaw the unit.
Long-term storage
If the pump is stored more than 6 months, the following apply:
• Before operating the pump after storage, it must be inspected with special attention to
the seals and the cable entry.
• The impeller/propeller must be rotated every other month to prevent the seals from
sticking together.
