As soon as you plug the mains plug into a socket supplying
.
230 V AC, the red and green LEDs light up – the pump starts.
The pump switches off once the max. pump pressure has been
reached (➔ the green Pump LED extinguishes).
If the pressure decreases below the switching pressure of
.
approx. 2.2 bar, the electronic control automatically switches
on the pump.
Note: Even the removal of a small quantity of water (several ml)
can lead to a pressure drop which is sufficient for the pump to
cut in.
Once you have finished drawing-off water, the maximum pres-
.
sure is created in the pipe. The pump then continues to run
for approx. 10 seconds before switching off.
The pump is switched off by the manometric switch if the liquid
.
to be pumped fails to flow (➔ dry-running safety).
A fault occurs if water cannot be pumped or if there is a lack
of water, for example:
If the flow rate is less than approx. 90 l / h
.
(➔ delivery side throttling)
If the flow rate is less than approx.400 l / h
.
(➔ inlet side throttling)
If there is a leak in the system causing the pump to switch on
.
and off more than 7 times within 2 minutes.
Due to a suction hose without a backflow preventer.
.
The pump attempts to restore normal operation in 4 minutes.
After a fault, the pump's electronic control unit makes three auto-
matic self-priming attempts at different time intervals (after 1 hour,
after 5 hours and after 20 hours) to restore normal operation.
The priming cycle (see above) is used for each of these attempts.
Important ! Remove the plug from the socket ! Check the unit
and pump for any faults (see section "Finding Faults"). Rectify
any faults and restart the pump by plugging the mains plug into
a socket supplying 230 V AC.
