Caution
We strongly recommend that all neptronic® products be wired to a separate
transformer and that transformer shall service only neptronic® products. This
precaution will prevent interference with, and/or possible damage to
incompatible equipment.
When multiple actuators are wired on a single transformer, polarity must be
observed. Long wiring runs create voltage drop which may affect the actuator
performance.

Mechanical installation
Mounting of the actuator on valve
- Screw completely the valve shaft (C) unto the coupling of the actuator (A).
- Unscrew the coupling (A) for ½ of turn in order to leave a functional play.
- Screw the counter nut (B).
Warning:
Do not over tight coupling of the actuator on the shaft of the valve.
Mounting of the actuated valve on system
- Pay attention to system particularity; be sure that the expansions, contractions of the system and its medium as well as operating pressures are within the tolerances.
- When plumbing, the motorized valve should be situated in an easily accessible place and sufficient space should be allowed for the removal of the actuator.
- To prevent moisture from collecting in the motor casing,install the motorized valve such that the actuator is superior to the valve, at 20-30º / at vertical. Avoid mounting the valve so that the valve stem is below horizontal.
