2. Receiving the product
2.1 Inspecting the product
The pump is delivered from the factory in a crate or a
wooden box specially designed for transport by a
forklift truck or a similar vehicle.
Upon receipt, check the pump visually to determine
whether any damage has happened to it during
transport or handling.
Check especially for these points:
1. broken or cracked equipment, including base
frame, motor or pump feet and flanges
2. broken motor fan cover, bent eyebolts or
damaged terminal box
3. missing parts.
Parts or accessories are sometimes wrapped
individually or fastened to the equipment.
If any damage or losses have occurred, notify
Grundfos' representative and the carrier's agent at
once.
Bolts for LSV bare-shaft pumps have US
threads for which inch tools are required.
Bolts for coupling guard and for mounting
of pump and motor on the base frame
have metric threads.

2.2 Temporary storage
If you do not install or operate the pump soon after
arrival, store it in a clean, dry place with slow,
moderate changes in ambient temperature. Protect
the pump from moisture, dust, dirt and foreign
bodies. Avoid exposing the motor to direct, intense
sunlight, rain, snow, ice and also dust for an
extended period of time. Attach a covering structure
or an additional cover when using or storing the
product outdoors. Follow these precautions before
and during storage:
1. Make sure that the bearings are filled with the
recommended grease to prevent moisture from
entering around the shaft. See section
6.3.3
Lubrication.
2. Make sure that the inlet and outlet ports and all
other openings are covered with cardboard,
wood or masking tape to prevent foreign objects
from entering the pump.
3. Cover the unit with a tarpaulin or other suitable
covering if it is to be stored without a protective
covering.
4. Rotate the shaft two turns every two weeks to
prevent corrosion of the bearing surfaces and the
stuffing box or sticking of the shaft-seal faces.
3. Installing the product
3.1 Location
Install the pump with accessibility for inspection and
maintenance. Allow ample space and headroom for
the use of an overhead crane or hoist sufficiently
strong to lift the unit.
Install the pump as close as possible to the pump
liquid supply, so that the inlet pipe is as short and
direct as possible.
3.2 Mechanical installation
WARNING
Crushing hazard
Death or serious personal injury
- Make sure that all installations are
performed by persons experienced in
the placement, alignment and
connection of pumping equipment.
