INSTALLATION
a. Install the actuator in a covered area and, in any case,
protect it against weather agents.
b. Make sure that data shown on actuator label is
compatible with actual operating requirements.
c. In case of impulse line not being incorporated in the
pressure regulator, connect the (A) from the pipe
downstream of the actuator to a straight pipe section
possibly away from restrictions, curves or branches in
order to avoid any variations in device triggering values
which might be caused by gas turbulence (see Figure 7).
