English
With the decrease in total water flow the
water runs through the water inlet, the
swimmer tank, advance pressure pump hot
water and through the high-pressure pump
to the high-pressure outlet.
6,5...9,5
If only a part of the water capacity fed from
< 2000 µS/cm the pump is needed, the rest of the flow
runs through the flow regulator back to the
< 0.5 mg/l *
suction site of the high-pressure pump.
< 20 mg/l
Detergent is drawn in by the high-pressure
pump and dispened manually through the
< 20 mg/l
detergent dispenser.
< 300 mg/l
< 85 mg/l **
If the system pressure falls during the
standy by period the opening of one of the
< 15 °dH **
power consuming devices, then the high-
< 0.5 mg/l pressure switch will start the pump.
< 0.05 mg/l
If the water rises in the flow regulator as a
< 0.02 mg/l
result of low or no water removal, the pres-
sure on the low pressure switch will also
rise. If the pressure passes a limit, then the
shut-down process will begin.
– After a few seconds the pump will stop
and the stand-by period will begin.
– If water removal takes place during the
stand-by period, then the pump will start
once again.
– At the end of the stanby-by period the
installation is started up by switching the
emergency-stop switch off and on or by
pressing the remote control button (op-
tional).
