Prerequisites
WARNING:
1. If mounting the actuator to a valve already
in line:
•
Close the shut-off valves in the piping
(upstream first, then downstream).
Or
•
Switch off the pump to allow the
differential pressure in the valve to
drop.
2. Disconnect the controller power before
replacing the actuator.
Installation
Mounting the SFP Actuator to a Valve
1. Place the actuator on the valve and firmly hand-tighten the
coupling piece.
2. Connect the wires. See Wiring.
Mounting the SFA Actuator on a Valve
CAUTION:
The black actuator attachment support ring
must be in place on top of the valve bonnet
before installing the actuator.
If the support ring is not in place, damage to
the actuator connection may result.
1. Rotate the manual override lever and latch.
2. Place the actuator on the valve and firmly hand-tighten
the coupling piece.
CAUTION:
Failure to fully rotate the manual override
handle before hand tightening will hinder
proper valve close off.
3. Release manual override handle.
4. Connect the wires. See Wiring.
