3.1.4 Vertical placement of SB HF pump
Tank installation of SB HF
Place the pump on the bottom of the tank. The pump
must not run dry.
Well installation of SB HF
Install the pump so that the pump inlet is at least 1 m
above the bottom of the well to avoid suction of sand
and impurities. See fig.
Use rigid metal pipes to hang the pump, and secure
the pipes with brackets at the top of the well.
Secure the pump by attaching a wire to the lifting eye
on the top of the pump. Do not hang the pump on the
lifting wire.
3.1.5 Adjustment of the float switch
To make sure that the float switch can start and stop
the pump, adjust the start and stop level by changing
the free cable length between the float switch and
the lifting handle.
A reduced free cable length results in more starts
and stops and a small difference in level. The
minimum free cable length is 10-18 cm. See fig.
.
•
An increased free cable length results in fewer
starts and stops and a large difference in level.
Make sure that the float switch can move freely.
Make sure that the stop level does not fall below the
pump inlet strainer.
