Remedy
Open the isolating valve. If the Oxiperm Pro operates
in 60 Hz mode, check if the multifunction valve is set
to 6 bars at the overflow side. See also the
installation and operating instructions of the
multifunction valve.
Connect the multifunction valve at the pump. This will
prevent uncontrolled flow of the dosing liquid through
the dosing lines.
Check cable connection.
Connect temperature sensor.
Do not rub hands on/against the cover.
