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.

English (GB)

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.
