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. 3.
Use rigid metal pipes to hang the pump, and secure
the pipes with brackets at the top of the well.
Do not use the power cable to hang the
pump above the bottom 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. 4.
• 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.

7. Check that the pump stops after a few seconds.
During operation, the SB HF pump inlet
strainer must always be completely
submerged in liquid.
Do not run the SB HF pump against a
closed outlet valve.
Connect SB pumps to an external
controller.
4.1 SBA starting and stopping conditions
When water is consumed in the water supply system,
the pump starts when the starting conditions are
fulfilled. This happens for example when a tap is
opened which makes the pressure in the system
drop. The control unit stops the pump again when
consumption stops, that is when the tap is closed.
Starting conditions
The pump starts when one of the following
conditions is fulfilled:
• The flow rate is higher than the minimum flow
rate.
• The pressure is lower than the start pressure.
Stopping conditions
The pump stops with a time delay of 10 s when the
flow rate is lower than the minimum flow rate.
The start pressure and minimum flow rate values are
shown in section 9. Technical data.
Automatic restart of SBA pumps
SBA pump models with a float switch automatically
restart when water is added. Models without a float
switch will attempt to restart every 24 hours.

6. Product introduction
6.1 Product description
The pumps are submersible booster pumps available
in two main versions:
• pump with integrated inlet strainer with 1 mm
mesh
• pump with side inlet, which includes a flexible
inlet hose with floating inlet strainer with 1 mm
mesh.
Both versions are available with or without float
switch. The float switch can be used for automatic
operation or dry-running protection of the pump.
6.2 SB pumps
The SB submersible booster pump is available with
integrated inlet strainer or floating inlet strainer. The
SB pump must be connected to an external
controller, see section 3.6.2 Connecting to external
controller.
6.3 SB HF pumps
SB HF is a high-flow submersible pump with a
stainless steel body. The integrated inlet strainer
enables the pump to draw water from a low level in
the installation. The SB HF pump must be connected
to an external controller, see section
3.6.2 Connecting to external controller.
6.4 SBA pumps
The SBA pump is a complete submersible booster
pump available with integrated inlet strainer or
floating inlet strainer.
SBA has a built-in control unit, eliminating the need
for a controller.
The pump has built-in protection against
overheating.
6.5 SBA dry-running protection
The built-in control unit incorporates dry-running
protection that automatically stops the pump in case
of dry running.
The dry-running protection functions differently
during priming and operation.
6.5.1 Dry running during priming
If the control unit does not detect any pressure and
flow within 5 min after it has been connected to a
power supply and the pump has started, the dryrunning function is activated and the pump stops.
6.5.2 Dry running during operation
If the control unit does not detect any pressure and
flow within 40 s during normal operation, the dryrunning function is activated and the pump stops.
6.5.3 Resetting of dry-running alarm
If a dry-running alarm has been activated, you can
restart the pump manually by switching off the power
supply, wait for 2 min and reconnect power. If the
control unit does not detect any pressure and flow
within 40 s after restarting, the dry-running alarm is
reactivated.
