HydroPower® RO
Operation/Troubleshooting
5.4 Turning off the HydroPower RO
To switch off the HydroPower RO after finishing the work, proceed as
follows:
1. For a longer service life, the membrane should be flushed for
approximately five (5) minutes after work. To do this, set the upper
rotary switch to
“RO FLUSH” and the lower switch to “PURE”.
During this process, pure water continues to be dispensed to the
bar in a slightly reduced quantity. Therefore you can continue to
work while flushing the membrane.
2. Turn off the unit with the lower switch.
3. Disconnect the power supply and the water supply.
4. Remove the hoses from the front connections.

The HydroPower RO is now turned off and can be transported.

Troubleshooting
6.1
Procedures for troubleshooting
During operation, the following may occur:
6.1.1 Water pressure too low
`
The water pressure from the inlet is too low to provide the desired filter performance and
the pump turns off.
`
Check whether the inlet hose is kinked or if there is too little pressure at the
water inlet.
`
To start the pump, press the red “RESTART” button on the backside of the unit
for approximately five (5) seconds.
6.1.2 Overpressure
Overpressure can occur if the water pressure from the inlet is more than 87 PSI (6 bar).
To check the water pressure at the inlet, proceed as follows:
`
The pressure gauge indicates the line pressure.
`
As soon as the pump is turned on, the pressure increases by 58 PSI (4 bar).
If the inlet pressure is too high, connect a pressure reducer to the water inlet
and regulate the pressure down.
