Installation and Operation
Solenoid Operation
(For Existing LFF113RFP Installations Only)
The Solenoid is prewired to the existing Junction Box, and must
be rewired by a certified electrician. The solenoid is equipped
with a Solenoid Bypass valve (normally closed) which manually
closes the Main Valve when engaged.
Opening the Solenoid Bypass Valve pressurizes the Main Valve
cover as indicated by Pressure Gauge, closing the Main Valve.
Closing Solenoid Bypass Valve and opening the Manual Reset
Ball Valve returns the Main Valve to the full open position.
Pressure Gauge returns to zero when the Main Valve is fully
open.
NOTE: Manual Reset Ball Valve must be closed for normal
operation.
Installing the Flow Sensor
(Backfl ow Upgrade Kit Only)

WARNING
Certified electrician to connect main power and Flow Sensor to
Junction Box.

The Flow Sensor is installed in the discharge piping from the
RPZ relief valve. If the Flow Sensor senses water in the discharge piping, it will signal the Junction Box to close the valve.
Installation Notes
1. Install the supplied tee for the Flow Sensor in the RPZ discharge line in the HORIZONTAL position as shown below.
2. Cut Sensor Probes to length. The ends of the Sensor Probes
should be located between
eter from the pipe bottom. The probes MUST NOT BE less
than ¼" from the pipe wall.
