Installation
The submersible motor pump can be installed as follows:
• in a stationary position with fixed pipeline;
• in a stationary position with a flexible hose pipe.
NOTE: Never install the pump by suspending it unsupported from its delivery pipe or power cable. The submersible
motor pump must be suspended from the specially provided handle or be placed on the bottom of the shaft.
To guarantee that the pump works properly, the bottom of the shaft must be kept free of sludge and dirt. If the
water level sinks too far, any sludge in the shaft will dry out quickly and stop the pump from starting up. It is
therefore necessary to check the submersible motor pump regularly (by carrying out start-up tests). The
floater is adjusted in a way that the pump can immediately be started. The pump shaft should have minimum
dimensions of 40 x 40 x 50cm so that the floating switch can move freely.
Mains Supply
Your new submersible pump is equipped with a shock-proof plug according to regulations. The pump is designed to
be connected to a 230VAC~50Hz safety socket. Make sure that the socket is sufficiently secured (min. 6A) and is in
excellent condition. Insert the plug into the socket to operate the pump.
NOTE: If the mains cable or plug suffers any damage from external action, repairs to the cable are prohibited. This
work may only be performed by a qualified electrician.
Areas of Use
This pump is used primarily as cellar pump. When installed in a shaft, this pump provides protection from flooding.
The pump can also be used wherever water has to be moved from one place to another, e.g. in the home,
agriculture, horticulture, plumbing and many other applications.
Setting to Work
After having read these instructions carefully, you can set your pump to work, reconsidering the following items:
• check if the pump rests on the ground of the shaft;
• check if the pressure cord has been attached properly;
• check the electrical connection (230VAC~50 Hz);
• check if the socket is in good condition;
• make sure that water and humidity can never come to the mains supply;
• avoid dry-running.
Setting the ON/OFF Operating Point
The ON and OFF operating point of the float switch can be set by adjusting the float switch in its latching holder.
Before putting 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.
