Figure 1. Acceptable Mounting Positions.
The vertical position is recommended for mounting.
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.

Figure 2. Mounting the Actuator on a Valve.
The installation is now complete.
Removing the Actuator from a Valve
1. Disconnect the wiring.
2. Unscrew actuator-coupling piece from the valve body
threads.
3. Remove the actuator from the valve.
Wiring
• All wiring must conform to NEC and local codes and
regulations.
• Use earth ground isolating step-down Class 2
transformers.
NOTE: Do not use autotransformers.
• Determine the supply transformer rating by summing
the total VA of all actuators used. The maximum
rating for a Class 2 step-down transformer is 100 VA.
NOTE: It is recommended that one transformer power
no more than 10 actuators.
• SFA71U/SFP71U 24 Vac actuators: Wiring
connection can be made inside the actuator housing
(remove the housing top for access).
• Line voltage actuators: Wiring connection requires
junction box and flex conduit no further than
15 inches (381 mm) from actuator.

Manual Override
For manual positioning, rotate the manual override handle
clockwise 180°, and squeeze it to latch around protruding stop.
See Figure 7.
NOTE: The actuator will automatically unlatch when power
is applied.

Figure 7. Manual Override Handle Position.
When the manual override handle is at the "0" position, the
output shaft is retracted if the actuator is normally open, or
extended if normally closed. See Figure 8.
When the Manual Override handle is rotated to
position 1, the reverse is true. See Figure 9.
Start-Up
Check the wiring and the position indication.
