BYPASS SWITCH
It allows to exclude the sensor (signal pressure switch) that detects the correct cycling of the ERS. The
operation with the by-pass is necessary only in case of malfunctioning of the signal pressure switch (in example
if the system gets blocks, with the message “ SYSTEM BLOCKED”, not as consequence of a real hydraulic
problem, but just as consequence of the malfunctioning of the probe).
The bypass is used also during special operation like the shut-down procedure (washing with chemicals). The
bypass activation is automatically removed after one single production cycle. Don’t activate the by-pass if not
necessary.
BYPASS VALVE *
It allows to exclude the salinity probe that detects the water quality .In this case all the fresh water is diverted
to the tank, regardless off its quality.
PUMP SELECTION **
There are 4 options available:
P1 the system works with pump1 only. In this case the production and the electric consumption will be halved
P2 the system works with pump2 only. I In this case the production and the electric consumption will be halved
P1&P2 the system works with one pump only, alternating P1 and P2 every 20 minutes in order to balance the
wearing of the two pumps. In this case the production and the electric consumption will be halved
P1+P2 the system works with both pumps. In this case the production and the electric consumption will be the
nominal values.
LEVEL CONTROL *
Allows to set a working procedure with an automatic control: in this case it is possible to install one or two level
switches in the fresh water tank.
*Optional
**Not for the single pump watermakers
