16 NOTICE! The main pump is activated only when the circuit pressure reaches over 0,2 bar.
During this stage, a sudden drop in pressure may occur, caused by the air pumped into the circuit as a result of
activation of the main pump.
Turn the main pump on and off, from time to time, using the selector switch (F) to facilitate circuit bleeding and pres‐
surisation.
Make sure that the key-operated switch is set to "automatic".
If it is hard for the system to get up to pressure, close the valve (D).
If the pressure exceeds 1,5 bar, turn off the filling pump and temporarily open the spigot (D) until the correct pres‐
sure is reached.
Turn the selector switch (H) to deactivate the filling pump.
17 Close the valve (C).
18 Remove the pipes from the tank.
19 Remove the key from the selector switch (F) and store in a safe place.
After one hour of operation, check that the pressure is correct, and if it is not carry out the restore procedure (see
chapter "Pressure restore procedure" on page 312
