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

1. Rotate the manual override lever and latch.

• 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.

replacing the actuator.

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.

Required Tools

• Small flat-blade screwdriver

• Wire stripper

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.

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.
