NOTICE:
• Protect the product against humidity, heat sources, and mechanical damage.
• Do not place heavy weights on the packed product.
Freezing precautions
The unit is frost-proof while operating or immersed in liquid, but the impeller/propeller
and the shaft seal may freeze if the unit is lifted out of the liquid into a surrounding
temperature below freezing.
Follow these guidelines to avoid freezing damage:
When Guideline
Before storage • The unit must be allowed to run for a short time after raising it to
discharge remaining pumped liquid.
This does not apply to impeller/propeller units.
• 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 unit
in liquid before operating the unit.
NOTICE:
Never use a naked flame to thaw the unit.
Long-term storage
If the unit is stored more than six months, then the following apply:
• Before operating the unit 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.
