Note:
The optimum pump capacity is achieved by
selecting the largest discharge line diameter.
4.2
Fixing the float switch cable
How the float switch cable is fixed to the
device depends on the particular device
model. If necessary, insert the float switch
cable in the cable clip of the handle.
The following illustration shows the fixed float
switch cable.
A
Caution!
The float switch cable may be damaged.
Never pull on the float switch cable to change
its position in the cable holder!
4.3
Installation instructions
For the float switch to function properly, it
must be able to move freely.
Space requirement for DP 18-5 SA, DP 28-
10 S Inox: approx. 60 cm x 60 cm
Space requirement for SP 24-46 SG, SP
28-50 S Inox: approx. 70 cm x 70 cm.
Submerge the pump to no more than the
maximum immersion depth specified in the
technical data.
Install the pump such that the suction inlets
cannot be blocked by foreign objects. If
necessary place the pump on a support
surface.
Ensure sufficient upright stability.
B
Risk of electric shock from severed
cables!
Do not lift or transport the pump by the cables
or the discharge hose! The cables and the
discharge hose are not designed to withstand
the tensile stress produced by the weight of
the pump.
4.4
Installing the pump
1. Submerge pump at a slight angle to avoid
creating an air cushion on the underside,
which would prevent priming. Once the
pump is submerged, it can be placed up-
right.
2. Lower pump to the bottom of the fluid con-
tainer.
Use a strong rope fastened to the lifting
eye to lower the pump.
The pump can also be operated when sus-
pended by a rope.
3. Before operating the pump again, ensure
that the pump line has been completely
emptied.
5.1
Switching ON and OFF
After you have connected the pump to the
mains, it will be switched on
automatically by the float switch. The point in
time at which switching occurs depends on
the water level.
Adjusting the ON and OFF times for the
pump
The position of the float switch cable in the
cable holder can be changed. The time inter-
val between pump switch-on and switch-off is
thereby adjusted:
– 'Short' float switch cable: ON and OFF po-
sitions are close together.
– 'Long' float switch cable: ON and OFF po-
sitions are far apart.
A
Caution!
Attach the float cable so that the OFF posi-
tion is at least 150 mm above the base of the
pump. The pump may run dry and thereby be
damaged.
A
Caution!
The float switch must always be able to move
up and down to allow the pump to be
switched on and off.
