Basic operation
The systems of the DP series deliver water with an automatic osmosis management.
Water delivery is controlled by a maximum pressure switch inside the machine. When the
water demand ceases (for example, when the tap is closed on the permeate pipe), the
pressure rises up to the tripping value of the pressure switch (2.5 bar), and the control unit
will stop water delivery.
When there is a water demand (for example, when the tap is opened on the permeate
pipe), the pressure drops and the pressure switch will send a command for water delivery
to the control unit.
See the ELECTRONICS MANAGEMENT chapter for further details.
Emergency bypass
The versions with bypass function integrate a system which, if the system is locked, re-routes
the entire input water directly to the output by opening the solenoid valve. Doing so, even
if not treated, water can be delivered while waiting for technical support.
To pass from standard mode (osmosis) to emergency mode (bypass), activate the diverter
valve (8) bringing it to the bypass position.
NOTE: The bypass circuit is also protected by the fuse. If the system does not supply water
even after the bypass function is enabled, the fuse may need to be replaced.
Anti-ooding
The machine is equipped with an anti-ooding system, which can detect leaks in the
machine and will immediately stop water delivery. The system cannot detect and block
ooding from leaks outside the machine. If necessary, install management and control
devices for external ooding.
The manufacturer
cannot be held liable for any ood damage caused by leaking compo-
nents outside the machine.
