5. Starting up the product

5.1 Starting

Before starting the pump, check that the following

requirements are fulfilled:

• The pump is submerged in liquid. During normal

operation with a float switch in a stationery

installation, the inlet strainer of the pump must be

below the surface of the liquid.

• The pump is placed on a base so that the inlet

strainer is not blocked by sludge, mud or similar

materials.

• The pipe or hose connection is tight.

• The outlet pipe is open, that is, the pipe is not

blocked or bent,

• The pump is connected to the power supply in

accordance with the instructions.

• For pumps with a float switch, check that the float

switch will allow the pump to pump down to the

chosen level according to fig. 10. If you want to

pump below this level, hold the float switch in

vertical position.

Startup procedure

Switch on the pump and check the following:

• The pump is operating properly.

• Water is being pumped.

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 power

supply to the pump is routed

through a ground fault circuit

interrupter (GFCI) in accordance

with state, local governing codes

and regulations.

DANGER

Electric shock

Death or serious personal injury

- Pump installation in a sump pit,

basin or tank must be carried out

by qualified, specially trained

persons in accordance with the

National Electrical Code (USA), the

English (US)

5.2 Venting the product

The pump is self-venting. A vent valve is built into

the lifting handle. The valve allows air to escape from

the pump in case the free air flow through the outlet

pipe is blocked. Once the pump is vented, the valve

normally closes.

If the pump sucks air or water with a high air content,

the valve may leak a mixture of air and water. This is

not a fault but a natural consequence of the opening

and closing of the valve.

Fig. 12 Self-venting

5.3 Manual operation

Start and stop the pump via an external switch.

To eliminate the risk of dry running, check the water

level regularly during operation. This can for instance

be done by means of an external level controller.

In order for the pump to be able to self-prime when

started, the water level must be at least 1 inch (25

mm).

When the pump sucks water, it can pump down to

0.8 inch (20 mm) water level.

5.4 Automatic operation with float switch

During automatic operation, the pump starts and

stop, depending on the water level, the float switch

position and cable length.

5.4.1 Forced operation of a pump with a float

switch

If the pump is used to drain water below the stop

level of the float switch, the float switch can be kept

in a higher position by fixing it to the outlet pipe.

During forced operation, the water level must be

checked regularly to prevent dry running.

5.5 Pumping to a low water level

The pump can pump down to 0.12 inch (3 mm) when

the inlet strainer is removed.

These conditions must be fulfilled:

• The inlet strainer must be removed.

• The pump must be placed on an even, horizontal

surface.

• The water must not contain particles which may

block the pump inlet.

• The water level must be minimum 0.2 inch (5

mm) when the pump is started.

Fig. 13 Low water level

Removing the inlet strainer

To remove the inlet strainer, insert a screwdriver

between the pump housing and the inlet strainer and

turn it.

Fig. 14 Removal of the inlet strainer

5.6 Thermal protection

If the pump is running without water, or if it is

otherwise overloaded, the built-in thermal switch will

cut out.

When the motor has cooled to normal temperature, it

restarts automatically.
