Factory settings

The device leaves the factory with a series of preset parameters which may be changed according to the user's
requirements. Each change of the settings is automatically saved in the memory and, if desired, it is always possible to
restore the factory conditions (see Restoring the factory settings par par 7.3 - Restoring the factory settings).
7.3

Restoring the factory settings

To restore the factory values, switch off the device, wait until the display has switched off completely, press and hold
down the "SET" and "+" keys and turn on the power; release the two keys only when the letters "EE" appear.
This restores the factory settings (a message and a rereading on EEPROM of the factory settings permanently saved in
the FLASH memory).
Once all the parameters have been set, the device returns to normal operation.
NOTE: Once the factory values have been restored it will be necessary to reset all the parameters that characterise the
system (gains, setpoint pressure, etc.) as at the first installation.

8. PARTICULAR INSTALLATIONS

8.1 – e18
The product is made and supplied with the capacity of being self-priming. With reference to par. 4, the system is able to
prime and therefore operate in whatever installation configuration chosen: below head or above head. However there are
cases in which the self-priming capacity is not necessary, or areas where it is forbidden to use self-priming pumps.
During priming the pump obliges part of the water already under pressure to return to the suction part until a pressure
value is reached at delivery whereby the system can be considered primed. At this point the recirculating channel closes
automatically. This phase is repeated each time the pump is switched on, even already primed, until the same pressure
value that closes the recirculating channel is reached (about 1 bar).
When the water arrives at the system intake already under pressure or when the installation is always below head, it is
possible (and mandatory where local regulations require it) to force the closure of the recirculating pipe, losing the self-
priming capacity. This obtains the advantage of eliminating the clicking noise of the pipe shutter each time the system is
switched on.
To force closure of the self-priming pipe, proceed as follows:
1. Disconnect the power supply;
2. empty the system;
3. remove the drainage cap, taking care to make sure the O-Ring does not fall (Fig. 5) (Fig.5);
4. with the aid of pliers take the shutter out of its seat. The shutter will be extracted together with the O-Ring and
the metal spring with which it is assembled;
5. remove the spring from the shutter; insert the shutter in its seat again with the respective O-Ring (side with
gasket towards the inside of the pump, stem with cross-shaped fins towards the outside);
