be noisy initially until any air has been purged from the system.
Continue to add water and the pump should switch to full power and the alarm contacts
should open. Do not continue to add water if it becomes visible in the breather tube.

SAHARA
Pump is pumping air:
Check that the sensor is in the correct
orientation.
Check the tube between sensor and
pump.
Check that the pump outlet tube is not
syphoning.
Check sensor for dirt or mould.
Trouble Shooting
Pump does not run:
Check fuse and electrical supply connections.
Check that water is reaching the pump sensor
in sufficient quantities to start the pump.
Check the sensor connector is plugged into the
pump.
Pump is noisy:
Check that the
, mains cable and
outlet tube are not vibrating against the sides of
the equipment.
Pump continues to run with no water:
The water sensor can become over sensitive if
contaminated by dirt or certain cleaning
chemicals. If this occurs the pump may
continue to run with no water. Disconnect the
sensor from the pump and flush the
sensor by pouring clean tap water into the inlet
for around 30 seconds (Fig. 11).
If the problem persists, flush with methylated
spirit and then rinse with water.
In dirty environments an in-line filter is
recommended to avoid pump and sensor
damage.
