RUNNING THE UNIT
• If you open the outlet valve the controller will detect a drop in
pressure and start the pump.
When operational breakdowns occur, such as water loss, obstruction of the
suction pipe, etc, the controller recognizes the problem and the red “Failure”
LED lights up at the same time as the power to the pump is cut to prevent
damage caused by dry running. If this should occur:
1. Switch off the controller at the mains.
2. Rectify the problem.
3. Switch on the controller at the mains and press the AUTO button.
The most common problems associated with water pump operation are leaks
on the SUCTION side of the pump. Even a pin hole in the inlet hose is sufficient
to seriously reduce suction.
Using the automatic mode can avoid the issue of the pump not starting if the
artificial starting pressure does not match the pump head in normal mode.
In certain conditions the pump may not start in Automatic Mode, in which
case run the unit manually before increasing the starting pressure to a suitable
value.
