EUROM SPV550i-Prof Instructions De Service page 18

Connect the hose to the pump outlet; you may use a hose clamp for a flexible hose.
The SPV750i(s) has also a 2" female thread. In addition, the SPV750is has a two-inch
(50 mm) tulle.
Connection of the Float Switch
The pump has an adjustable float switch. This float switch will automatically switch on
the pump, when the water reaches a level of approx. 25 cm, and will automatically
switch off the pump, when the water reaches a level of approx. 15 cm. The points at
which this switch switches on and off can be adjusted by giving the float slightly more
or less space by shortening/loosening the float cable using the clamp on the handle.
Before using the pump, you should check the following:

The float switch should be set in such a manner that the float can reach the points
at which it switches on and off easily and without effort. To check this, you put the
pump in a barrel filled with water. Carefully, lift and lower the float switch
manually. You can then feel when the pump switches on and off and you can
adjust these points by slightly shortening/loosening the float cable using the
clamp.
 Make sure that the distance between the float and the cable clamp on the handle is
not too short. The float switch needs some space to operate smoothly.

If you set the float switch, make sure that it does not touch the bottom before you
switch off the pump. Also prevent the pump from hanging on to something. If the
float does not signal 'OFF', the pump will continue to pump and ultimately, run dry
or burn.
Putting in Place and Moving
- Make sure that the pump is positioned sturdily, especially if you let it operate
automatically.
- Make sure that the float can move freely, especially in case of automatic
operation.
- Make sure that the pump is positioned in a manner that does not block / partially
block the suction openings at the bottom of the pump. We recommend putting the
pump on a tile (for example), if it is going to stand on a soft underground (e.g.,
sand).
- Do NOT use the electrical cable or the float
switch to lift or hang the pump. If you want
to lower the pump into a well or shaft (for
example), use a piece of rope that you
attach to the handle.
- Your pump is constructed to include
automatic bleeding through which air in the
pump can be released if you submerge it in
water. Therefore, the air bubbles that
appear do not indicate a malfunction but are
normal.
- The pump should not be submerged more
than 5 metres. Do not put it into mud: this might cause blockage due to plant
