The pump:
When the regulation device must be stored, clean water should be pumped through the hose in order to rinse
it. Then position the roller arm at 45°, turning it clockwise.
These two precautions will facilitate subsequent reactivation of the device.
Keep away from freezing conditions.
The probe:
Extract the pH probe from the relative probe holder. Replace it in the original bottle filled with tap water. If
necessary, close the probe holder using a plug the size of a 5 euro cent coin.
! Keep away from freezing conditions, intense heat and direct sunlight.
! DO NOT INSERT EXCESSIVE QUANTITIES of chemical product above the probe.
As the pH electrode is comprised of glass elements, handle it with care.
The alarms
OFA (overdose alarm):
First OFA alarm: the ALARM light flashes; activation after 3 consecutive dosing cycles in which the set value was
not reached; the system continues to guarantee the measurement and dosing functions.
Second OFA alarm: the ALARM light flashes and the Hold light comes on; the dosing pump is blocked. The alarm is
activated after 4 consecutive dosing cycles in which the set level was not reached; to return to normal operation,
press the : button: the device resets the alarms and returns to normal measuring and dosing mode.
Flow: presence of incoming flow (enslavement by the filter pump).
