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 da-
mage 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 immediately
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. 4 page 69):
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. 5
page 69).
Do not stand close to the pump during handling.
Always wear personal protection equipment.
!
NEVER handle the product by means of the power supply or signalling wiring.
warning
Within a hazardous area, handle any moving with caution, avoiding bumps or friction of the pump with other metallic objects as
this could cause sparks, therefore increasing the risk of explosions.

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 damaging
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 exposed
to low temperatures.
!
Turn the impeller by hand occasionally (at least every 2 months) through the outlet or intake, to prevent the mechanical
warning
seals from sticking together.

3. INSTALLATION

3.1 General safety precautions

•
Fence off the working area by appropriate means and wear personal protection equipment.
•
The pump must be lowered into the tank using a sling or chain of suitable size tied to the handle.
•
Check the electric cable and gaskets for damage and make sure that the impeller turns freely.
•
The size of the tank in which the pump is installed must be such that:
•
any level float switches are able to move freely;
•
the number of pump switch on/switch off cycles does not exceed the permitted number stated in the technical information;
•
To prevent the cavitation problems caused if the pump draws in air, ensure that the liquids do not flow into the tank near to or towards the pump.
•
Check that the minimum liquid level is correct in relation to the duty point to obtain trouble-free operation and satisfactory cooling of the pump.
•
Make sure that the pump does not operate off its characteristic curve.
•
Do not install the pump in zones with an explosion risk (except for models with explosion-proof certification).
The shock from built up electrostatic charges on isolated components could cause an explosion. -EX pumps do not have isolated
components that are electrostatically chargeable and they are all equipped with screw for connection to the equipotential ground
network (Fig. 6 page 69).
Any additional components installed in the hazardous area must be connected to the earthing network according to the EN 1127-
1 rule, part 6.4.7.
Check the suitability for use in potentially explosive atmospheres of each additional component installed in the hazardous area.

3.2 Checking the impeller rotation direction

Before making the definitive electrical connection, a skilled technician must make sure the impeller rotation direction is correct.
The pump carries a decal which indicates the correct impeller rotation direction (green arrow) and the relative kickback direction (red arrow) when
the pump is viewed from above (Fig. 2b page 69).
