Trouble Shooting
Pump does not run:
Check fuse and electrical supply
connections.
Check that water is reaching the pump
sensor.
Pump continues to run with no water:
The water sensor can become over
sensitive if contaminated by dirt, mould or
certain cleaning chemicals. If this occurs
the pump may continue to run with no
water. Disconnect the YUMA from the
mains supply and flush the sensor by
pouring clean tap water into the inlet for
around 30 seconds (Fig. 6). If the problem
persists, flush with methylated spirit and
then rinse with water.
Pump is noisy:
Check that the YUMA, mains cable and
outlet tube are not vibrating against the
sides of the equipment.
Fig.6.
Pump is pumping air:
Check that the YUMA is in the correct
orientation.
Check that the outlet tube is not syphoning.
In dirty environments an in-line filter is
recommended to avoid pump and sensor
damage.
