2 PRELIMINARY INSPECTION
2.1 Delivery and packing
The pumps are supplied in their original packing, in which they should remain until
the time of installation.
be damaged, inform the reseller immediately. The pump should not be exposed to
unnecessary shocks and impacts.
2.2 Contents of packing
The packing contains the operating and installation manual and the electric pump.
3 STORAGE AND HANDLING
3.1 Storage:
Storage temperature: from -5°C to +40°C.
The electric pump must be kept indoors in a dry place, away from heat and protected
from dirt and vibrations.
3.2 Handling:
WARNING : Observe the accident prevention regulations in force. Risk of
crushing. The pump may be heavy. Use suitable lifting methods and always
wear personal protection equipment.
Before handling the product, check its weight to identify suitable lifting equipment.
The weight is indicated on the pump data plate.
There are two possible methods for handling the pump:
1) Where indicated, remove the cap and screw on a lifting eyebolt suitable for the
weight involved. Warning: The eyebolt does not correspond to the centre of
gravity (see fig. 1-C).
2) Position the hoist cables as shown in (fig. 1-A) and (fig. 1-B).
Take the pump out of its packing and check that it is in good condition.
Check also that the plate data correspond to those required. In the event of any
anomaly, contact the supplier immediately, reporting the nature of the defects.
