1.3 Notes

The symbols and notes below may appear in

Grundfos installation and operating instructions,

safety instructions and service instructions.

2. Installing the product

2.1 Pump location

Install the pump in a dry well-ventilated location.

Protect the pump from rain, frost and direct sunlight.

We recommend that you place the pump as close as

possible to the liquid to be pumped.

2.2 Mechanical installation

2.2.1 Foundation

Fasten the pump to a solid horizontal foundation by

means of screws through the holes in the base plate.

NS pumps can be installed in horizontal or vertical

position. If the pump is installed in vertical position,

the motor must be above the pump.

PF pumps must only be installed in horizontal

position.

2.2.2 Pipework

Make sure that the pump is not stressed by the

pipework.

Fit rigid pipes with pipe hangers.

Use sealing tape on the inlet and outlet ports of the

pump.

2.3 Electrical connection

Observe these instructions for explosion-

proof products.

A blue or grey circle with a white graphical

symbol indicates that an action must be

taken.

A red or grey circle with a diagonal bar,

possibly with a black graphical symbol,

indicates that an action must not be taken

or must be stopped.

If these instructions are not observed, it

may result in malfunction or damage to the

equipment.

Tips and advice that make the work easier.

Observe local regulations concerning

limits for manual lifting or handling.

CAUTION

Crushing of feet

Minor or moderate personal injury

- Use safety shoes when handling the

pump.

DANGER

Electric shock

Death or serious personal injury

- Before starting any work on the product,

make sure that the power supply has

been switched off and that it cannot be

accidentally switched on.

DANGER

Electric shock

Death or serious personal injury

- The protective earth of the socket outlet

must be connected to the protective

earth of the pump. The plug must

therefore have the same PE connection

system as that of the socket outlet. If

not, use a suitable adapter.

We recommend that you fit the permanent

installation with a residual-current circuit

breaker, RCCB, with a tripping current less

than 30 mA.

DANGER

Electric shock

Death or serious personal injury

- If the pump is used for cleaning or other

maintenance of swimming pools,

garden ponds or similar places, make

sure that the pump is supplied through a

residual-current circuit breaker, RCCB,

with a tripping current of 30 mA.

DANGER

Electric shock

Death or serious personal injury

- Power supply cables without a plug

must be connected to a supply

disconnecting device incorporated in

the fixed wiring according to the local

wiring rules.

DANGER

Electric shock

Death or serious personal injury

- The pump must be earthed.

5.1 Product description

Grundfos NS pumps are centrifugal pumps designed

for lifting water in domestic, industrial and

agricultural installations.

The pumps come in two versions:

• single-impeller pumps

• twin-impeller pumps.

Grundfos PF pumps are compact peripheral

centrifugal pumps that can generate high heads.

Always tighten plastic plugs by hand to

avoid damage to the threads.

7. Fault finding

DANGER

Electric shock

Death or serious personal injury

- Before starting any work on the product,

make sure that the power supply has

been switched off and that it cannot be

accidentally switched on.

CAUTION

Chemical hazard

Minor or moderate personal injury

- Make sure that the product has only

been used for water. If the product has

been used for pumping aggressive

liquids, flush the system with clean

water before you start work on the

product.

Fault Cause Remedy

1. The pump does not

start.

a) Supply failure. Cut in the circuit breaker or replace the

fuses. If the new fuses also blow, check

the electrical installation.

b) The pump is blocked by impurities. Clean the pump. Check or replace the

strainer in the inlet pipe.

c) The motor is defective. Replace the pump.

2. The pump runs, but

gives no or just a

little water.

a) The pump is not filled with water. Prime the pump. See section

3.1 Priming.

b) The inlet pipe is blocked by

impurities.

Clean the pump. Check or replace the

strainer in the inlet pipe.

c) The pump is blocked by impurities. Clean the pump. Check or replace the

strainer in the inlet pipe.

d) The suction lift is too high, that is

higher than 7 metres.

Change the position of the pump.

e) The inlet pipe is too long. Change the position of the pump.

f) The diameter of the inlet pipe is too

small.

Replace the inlet pipe.

g) The inlet pipe is not immersed

deeply enough.

Make sure that the inlet pipe is

immersed sufficiently.

h) The inlet pipe is leaking. Repair or replace the pipe.

3. The pump runs, but

gives no water or

delivers a reduced

quantity of water at

high pressure.

a) The outlet pipe is blocked. Clean the pipe or open the isolating

valves, if any.

Check that no additional work is being

carried out in the system.

4. The pump stops

during operation.

a) Single-phase motors:

The thermal switch in the motor

has tripped due to overheating.

The thermal switch cuts in

automatically when the motor has

cooled sufficiently.

If the problem still persists, check these

two possible causes:

• The impeller is stuck.

Clean the pump.

• The motor is defective.

Replace the pump.
