3 Product Description
2.2.1 Lifting
Always inspect the lifting equipment and tackle before starting any
work.
WARNING: Crush Hazard
1) Always lift the unit by its designated lifting points. 2) Use
suitable lifting equipment and ensure that the product is
properly harnessed. 3) Wear personal protective equipment.
4) Stay clear of cables and suspended loads.
NOTICE:
Never lift the unit by its cables or hose.
Lifting equipment
Lifting equipment is always required to handle the unit. The lifting
equipment must fulfill the following requirements:
• The minimum height between the lifting hook and the floor must be
sufficient to lift the unit. Contact a Xylem representative for more in-
formation.
• The lifting equipment must be able to hoist the unit straight up and
down, preferably without the need for resetting the lifting hook.
• The lifting equipment must be correctly anchored and in good con-
dition.
• The lifting equipment must support the weight of the entire assem-
bly. Only authorized personnel may use the lifting equipment.
• Two sets of lifting equipment must be used to lift the unit for repair
work.
• The lifting equipment must be dimensioned to lift the unit with any
remaining pumped media in it.
• The lifting equipment must not be oversized.
CAUTION: Crush Hazard
Over-dimensioned lifting equipment can lead to injury. A
site-specific risk analysis must be done.
2.3 Temperature ranges for transportation,
handling and storage
Handling at freezing temperature
At temperatures below freezing, the product and all installation equip-
ment, 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 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 im-
mersed in liquid, but the impeller/propeller and the shaft seal may
freeze if the unit is lifted out of the liquid into a surrounding tempera-
ture below freezing.
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.
Water-glycol mixtures: Units equipped with an internal closed-loop
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).
4
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.
2.4 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 pre-
vent the seals from sticking together.
