- Check if socket is in good condition.
- Make sure that water and humidity can never come to the mains supply.
- Avoid pump running dry.
 MAINTENANCE GUIDELINES
This submersible pump is an approved maintenance-free high quality product which is subject
to severe final controls. We recommend regular inspection and maintenance to ensure long
equipment life and uninterrupted operation.
Important:
-
Remove the mains plug before all maintenance work.
-
In the event that the pump is often transported in the course of operation, it should be cleaned out
with clear water after every use.
-
In case of stationary installation, the function of the floating switch should be checked every 3 months.
-
All fibrous particles which may have built-up inside the pump housing should be removed with a water
jet.
-
Every 3 months the shaft ground should be cleaned from mud.
-
Remove deposits on the floater with clear water.
 CLEANING THE IMPELLER
If excessive deposits collect in the pump case you must dismantle the bottom part of the pump
as follows:
1. Remove the intake cage from the pump case.
2. Clean the impeller with clear water. Important: Do not put down or rest the pump on
the impeller!
3. Assemble is reverse order
 SETTING THE ON/OFF OPERATION POINT
The ON and OFF operation point of the float switch can be set by adjusting the float switch in its
latching holder.
Before you put the pump into operation, please check the following:
-
The float switch must be installed so that the level of the ON operating point and the level of the OFF
operating point can be reached easily and with little force. To check this, place the pump in a vessel
filled with water, raise the float switch carefully by hand and then lower it again. As you do so, note
whether the pump switches on and off.
-
Make sure that the distance between the float switch head and the latching holder is not too small.
Proper operation is not guaranteed if the gap is too small.
-
When you set the float switch, make sure that it does not touch the base before the pump switches
off. Caution: risk of dry-running.
