2. TRANSPORT AND STORAGE

2.1 Visual inspection

Make a visual inspection of the packaging for damage. Record any significant damage to the product in the transport documents.
If articles are missing, contact Zenit (or its dealer) or the forwarders.
Remove the packaging materials and dispose of them as required by law. Take special care not to injure yourself with sharp tools and not to
damage to the product, especially the electrical wiring.
Inspect the product to ensure that there are no damaged or missing parts.
Check that the data on the nameplate are the same as those of the product required.

2.2 Electrical cables protections

The ends of the electrical cables are protected with a heat-shrink sheath that stops liquids or humidity from getting in.
This protection does not ensure a water-tight seal and is only able to preserve the cable from water spray or similar (IP44).
Accordingly, do not immerse the ends of the cables in any sort of liquid, not even with the protections on, and only take the sheath off immedia-
tely before setting up the electrical connection to the electric pump.
If the storage location is subject to flooding, be careful to set the ends of the cable up at a higher level than the maximum possible flooding level.
Follow the instructions below to remove the heat-shrink sheath (Fig. 6):
1. cut across the end of the heat-shrink sheath;
2. make a lengthwise cut in the heat-shrink sheath, taking care not to damage the wires inside;
EN
3. open the flaps of the sheath to expose the wires, and slide the sheath off the cable.

2.3 Handling and lifting

The pump must be lifted and handled using a chain or sling secured to the handle on top, with suitable
machinery (crane, hoist, etc.).
Before lifting, make a note of the weight of the product stated on the nameplate and use certified slings, chains and
hooks of suitable load capacity.
Ensure that the electric pump is firmly secured and cannot fall, rotate or swing.
The handle on top is designed to ensure that the pump will be balanced during lifting; however, it may swing when lifted
off the ground (Fig. 7).
Do not stand close to the pump during handling.
Always wear personal protection equipment.
warning!
NEVER handle the product by means of the power supply or signalling wiring.
Make sure that the atmosphere in the working area is not potentially explosive.
The classification of the installation site must be approved by the local fire-fighting autorities in each individual case.

2.4 Storage

During storage, the electric pump must be kept in a suitable place, out of the reach of children or those with diminished responsibility, suitably
secured against falling and protected from damp, vibrations, dust and extreme temperatures (below -20°C/-4°F and above +60°C/140°F).
If the pump should freeze, do not use flames to remove the ice; immerse it in the liquid in which it is to be installed until it thaws out.
Models with cooling jacket use a 30% water-glycol mixture as coolant; this mixture retains its properties intact down to a temperature of -13°C
(9°F). At lower temperatures, the mixture becomes more viscose but it does not solidify completely, and it can therefore be used without dama-
ging the pump.
However, the condition of the coolant mixture and the mechanical seal sump oil should be checked before using the product if it has been expo-
sed to low temperatures.
warning!
Turn the impeller by hand occasionally (at least every 2 months) through the outlet or intake, to prevent the mechanical
seals from sticking together.
