4.3 Installation.
The flow direction indicator installed on the valve must always be orien-
ted in the same direction as the system flow at the time the motor is
installed.
The motor can be installed with the cable outlet either on the right or on
the left of the valve itself without affecting the operation of the micro-
switch.
/ IP 50
Use a fixed wrench to perform one complete turn of the manoeuvre rod
of the valve.
Check and align, if necessary, the metal joint at the outlet of the servo-
motor with the manoeuvre rod of the valve; check that the servomotor is
perpendicular to the valve.
