Freezing precautions
The pump is frost-proof while operating or immersed in liquid, but the impeller/propeller and the shaft
seal may freeze if the pump is lifted out of the liquid into a surrounding temperature below freezing.
Follow these guidelines to avoid freezing damage:
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.
