Warning
Prior to installation, read these installation
and operating instructions. Installation and
operation must comply with local
regulations and accepted codes of good
practice.
Warning
If these safety instructions are not
observed, it may result in personal injury.
Caution
If these safety instructions are not
observed, it may result in malfunction or
damage to the equipment.
Note
Notes or instructions that make the job
easier and ensure safe operation.

3. Receiving the product
3.1 Delivery
The pumps are tested 100 % before leaving the
factory. The test includes a function test where the
pump performance is measured to ensure that the
pump meets the requirements of relevant standards.
Test certificates are available from Grundfos.
3.2 Transporting the product
Always transport the pump in the specified position.
During transport, the pump must be fastened
securely to prevent damage to the shaft and shaft
seal caused by excessive vibrations and knocks. Do
not lift the pump by means of the shaft.
3.3 Handling the product
Weight: See label on the packing.
Lift the pumps by means of nylon straps and
shackles or a hook as shown on figs 1to 3.
Fig. 1 Correct lifting of pump without base
frame
Fig. 2 Correct lifting of pump with base frame
Fig. 3 Correct lifting of pump without motor
Fig. 4 Incorrect lifting of pump
Warning
Pay attention to the pump weight, and take
precautions to prevent personal injury if
the pump should topple or fall by accident.
Warning
Motors from 4 kW and up are supplied with
lifting eyes which must not be used for
lifting the entire pump unit. See fig. 4.

3.4 Storing the product
The contractor must inspect the equipment on
delivery and make sure that it is stored in such a way
that corrosion and damage are avoided. If more than
six months will pass before the equipment is put into
operation, please consider applying a suitable
corrosion inhibitor to the internal pump parts.
Make sure that the corrosion inhibitor used does not
affect the rubber parts with which it comes into
contact.
Make sure that the corrosion inhibitor can easily be
removed.
To prevent water, dust, etc. from entering the pump,
keep all openings covered until the pipes are to be
fitted. The cost of having to dismantle the pump
during startup to remove foreign objects can be very
high.
