Pump release.
If aer a long period of inactivity, the circulator is blocked, adjust the screw in the centre of the head in order to manually release the mo-
tor sha.
Take great care during this operation to avoid damage to the motor.
Bypass Adjustment (Parag.1.36).
e appliance leaves the factory with the bypass open.
If necessary, the by-pass can be regulated to system requirements from minimum (by-pass closed) to maximum (by-pass open).
Adjust using a at head screwdriver, turn clockwise and open the by-pass, anticlockwise it is closed.
e bypass ensures minimum circulation of the water in the appliance and its correct operation if the systems are divided into
more than one zone.
Total head available to the system.
