In the case of a build-up of lime-scale (calcium deposits) use a mild descaling solution, following the instructions
provided for a “shower head”- we recommend RUBBEDIN DESCALE MAGIC – available from most Hardware’s and
Supermarkets.
*Be careful not to drop the ceramic shaft while cleaning the impeller as it is fragile and breaks easily.

TROUBLE SHOOTING
*Pump does not operate; please check the possible reasons:
1)
Clouds, dust or shade will cause the pump to stop.
2)
No connection to the power supply – check all the cables and connections.
3)
Impeller is blocked – clean the pump as described in
“CLEANING AND MAINTENANCE.”
4)
Check the water level, ensure the pump is fully submerged in water; low water level will cause it to stop.
5)
If all above are ok, try the spare impeller supplied with the pump.
6)
If pump does operate but there is no water running through the pipework: clean the pipework and the
filter to make sure there are no blockages.
If the SYSTEM indicator shows RED always and the pump does not work even though the solar module is in full
sunlight
MORE THAN ONE SHINING DAY,
please check the possible failures below:
1)
The CHARGE yellow indicator doesn’t lighten—check connection to the solar module.
2)
The battery is out of its service life and needs to be replaced. Replace the battery by following the steps
shown in the below photos.
Alternatively OUTPUT 1 (18V) pump may bypass the battery backup and
connect the pump to solar panel directly and the pump will get almost the same good performance on
sunny days.
If the SYSTEM indicator shows GREEN, and the pump still does not work,
please check the possible failures below:
1)
Check if the TIMER indicator lightens. Please note, in this mode, the pump runs intermittently.
2)
The pump is blocked, clean the pump by referring to pump manuals.
If the appliance is lights, please check the set manuals of lights.
