Temperature ranges for transportation, handling and storage
Handling at freezing temperature
At temperatures below freezing, the product and all installation equipment,
including the lifting gear, must be handled with extreme care.
Make sure that the product is warmed up to a temperature above the freezing
point before starting up. Avoid rotating the impeller/propeller by hand at
Transportation and Storage
8107.011/.030/.300/.590 Maxi Installation, Operation, and Maintenance Manual 7

temperatures below the freezing point. The recommended method to warm the
unit up is to submerge it in the liquid which will be pumped or mixed.
NOTICE:
Never use a naked flame to thaw the unit.
Unit in as-delivered condition
If the unit is still in the condition in which it left the factory - all packing
materials are undisturbed - then the acceptable temperature range during
transportation, handling and storage is: –50°C (–58ºF) to +60°C (+140ºF).
If the unit has been exposed to freezing temperatures, then allow it to reach the
ambient temperature of the sump before operating.
Lifting the unit out of liquid
The unit is normally protected from freezing 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.
Units equipped with an internal cooling system are filled with a mixture of water
and 30% glycol. This mixture remains a flowing liquid at temperatures down to –
13°C (9°F). Below –13°C (9°F), the viscosity increases such that the glycol
mixture will lose its flow properties. However, the glycol-water mixture will not
solidify completely and thus cannot harm the product.
Follow these guidelines to avoid freezing damage:
1. Empty all pumped liquid, if applicable.
2. Check all liquids used for lubrication or cooling, both oil and water-glycol
mixtures, for the presence of unacceptable amounts of water. Change if
needed.
Storage guidelines
Storage location
The product must be stored in a covered and dry location free from heat, dirt,
and vibrations.
NOTICE:
Protect the product against humidity, heat sources, and mechanical damage.
NOTICE:
Do not place heavy weights on the packed product.
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.
