1. Start the pump and measure the quantity of wa-

ter. 

2. Stop the pump, switch off the electricity supply 

and interchange any two of the incoming supply 
wires.

3. Restart the pump and measure the quantity of 

water. 

4. Stop the pump.

5. Compare the results taken under points 1 and 3. 

The connection which gave the larger quantity of 
water is the correct direction of rotation.

7. Start-up

• The SPO pump with base plate must be primed 

before starting.
Remove the priming plug at the top of the pump 
and prime the pump.
Make sure that both the pump and the suction 
pipe are filled with liquid. 

• Switch on the electricity supply and wait until the 

liquid starts running out of the discharge pipe. 

• If the pump does not operate satisfactorily, switch 

off the electricity supply and see section 

10. Fault 

finding chart

.

7.1 Adjustment of float switch

The pump stop level is set by changing the free ca-
ble length between the float switch and the fixing 
point (clamp on the pump handle), see fig. 7, pos. B.

It must be ensured,

• that the float switch can move freely.

• that the stop level does not fall below the pump 

suction strainer. 

Fig. 7 

8. Operation

Note: 

During operation, the pump suction strainer 

must always be completely submerged in the liquid 
to be pumped. 

If the pump has been used for liquids other than 
clean water, it should be flushed through with clean 
water immediately after use.

8.1 Periods of inactivity

If the pump is taken out of operation for a long pe-
riod, it should be drained. 

Pumps with base plate can be drained via the drain 
plug. 

8.2 Frequency of starts and stops

Maximum 30 per hour.

9. Maintenance and cleaning

During normal operation, the pump is maintenance-
free.

9.1 Cleaning the pump suction strainer

To clean the suction strainer, proceed as follows:

1. Place the pump in horizontal position. 

2. Remove the suction strainer cover by slackening 

the three screws with a screwdriver. 

3. Clean the inside of the suction strainer. 

4. Check that the slots of the suction strainer are 

free from foreign bodies. 

5. Refit the suction strainer cover and reinstall the 

pump. 

9.2 Checking the motor shaft

If the motor does not operate and the shaft does not 
rotate when the electricity supply is switched on or 
the float is activated, it must be checked whether all 
rotating parts can rotate freely. 

Proceed as follows:

1. Place the pump in horizontal position. 

2. Remove the suction strainer cover by slackening 

the three screws with a screwdriver. 

3. Slacken the self-locking nut and turn the motor 

shaft clockwise. 

4. Refit the suction strainer cover and reinstall the 

pump.

Before starting work on the pump/motor, 
make sure that the electricity supply has 
been switched off and that it cannot be ac-
cidentally switched on.
