Operation - EUROM Flow 250 Operating Instructions Manual

Attaching the float switch
The pump is equipped with an adjustable float switch. You adjust the points at which the
pump switches itself on and off by shortening or lengthening the float cable using the
attachment on the handle.
You must check the following before using the pump for the first time:
•
The float switch must be set so that the pump can reach the points at which it must
switch itself on and off easily and without any force. In order to check this, you must
place the pump in a container filled with water. Manually lift the float switch gently and
then allow it to descend. You will feel when the pump switches on and off and can
modify these points, if necessary, by shortening or lengthening the float cable via the
catch.
•
Do not make the distance between the float and the cable catch on the handle too
short; the float switch needs a little space in order to run smoothly.
•
When setting the float switch, ensure that it does not touch the bottom before the
pump switches off. Make sure that the float cannot get caught on anything. If the float
cannot transmit the 'OFF' signal, the pump will continue to work until it runs dry and
burns itself out.
Locating and moving
• Make sure the pump is positioned at a stable location, particularly if you want it to
work automatically.
• Ensure that the float can move around freely, particularly if it is to work automatically;
a possible shaft should be at least 40x40x50 cm. great!
• Ensure that the suction openings are not blocked (not even partially). If the pump is
positioned on a soft surface (e.g. a sand bed), place it on a tile or something similar.
• Do not use the electrical cable or float cable to lift the pump or hang it up. If you wish
to locate the pump in a water source or shaft, use a rope that is attached to the handle
to do so.

Operation

Before use, check that the values of the socket to which you wish to connect the pump
correspond to those on the type plate on the pump itself (230V-50Hz) and that the socket
is earthed (max. 30mAmp) and has an earth leakage circuit breaker (nominal voltage ≤30
mA). Make sure that no people present in the space to be pumped out (cellar/boat/pond
etc).
Automated function
Once you have plugged the device into the socket, the pump will switch on automatically
when the water exceeds the set minimum level and switch off when the set minimum
level has been obtained.
