910 Ops & Inst
Proper Automatic Control Valve start-up requires bringing the valve into service in a controlled manner. All
adjustments to control pilots and speed controls should be made slowly, allowing the valve to respond and
the system to stabilize. NOTE: Control Valves should be set-up in a dynamic (flowing) condition for
proper start-up. Provisions for flow must be made to insure proper settings.
1. Refer to valve schematic. Disengage Solenoid by turning Manual Operator out (counterclockwise)
Open upstream and downstream isolation valves to allow controlled filling of the Valve and Backflow
Assembly. Open all Isolation Ball Valves. Adjust speed controls by turning needle in (clockwise) until
seated, and return out (counterclockwise) 2-1/2 to 3-1/2 turns. These are approximate settings, and
should be fine tuned to suit system requirements.
2. Open Manual Reset Ball Valve. Inlet pressure will activate the Model 22-1 Accelerator and open
the valve fully. Inlet pressure will be indicated on Pressure Gauge. Close Manual Reset Ball Valve
“trapping” pressure in cover of Model 22-1 Accelerator.
3. Engage Solenoid by turning (red) Manual Operator clockwise (in) to simulate electrical shutdown
signal. Pilot Pressure Gauge will drop to zero and valve will begin to close. Due to low / no flow
condition, valve closure may be slower than normal operation. When valve is fully closed adjust
Limit Switch trip arm and trip collar to actuate Limit Switch.
4. Disengage Solenoid by returning Manual Operator out (counterclockwise) and open Manual Reset
Ball Valve. Inlet pressure will be indicated on Pressure Gauge. Close Manual Reset Ball Valve.
Valve will open fully and is ready for electrical activation.
5. Open JB113 Junction Box. Apply power and observe the clear Electric Relay Control.
6. Pour adequate amount of water into RPZ Relief Valve Air Gap until the RED LED indicator light on
the Electrical Relay illuminates / flashes. This indicates the FS99 Flow Sensor is properly installed
and is sensing water in the discharge piping.
7. Trap water in discharge piping and observe RED LED on Electrical Relay. Solenoid will energize
when duration of Adjust Time Delay elapses. Valve will go closed and must be manually reset.
Adjust Time Delay to Customer / Project specifications. To manually reset valve refer to Step 4.
8. For final test simulate actual RPZ Relief Valve discharge and observe floor drain for excessive
pooling or flooding. Re-adjust time delay and valve speed controls as needed to achieve desired
valve closure time.
