Thank you for purchasing a Rain Bird G4 Solenoid. This solenoid assembly is compat- ible with the following Rain Bird valves: PGA, PEB, PESB, EFB-CP, and BPES.
Installation Refer to F1.
- WARNING: Turn off water supply and dis- connect all electrical power
- Turn the solenoid counter-clockwise to remove the G4 Solenoid. B
- If desired, use an open-ended wrench to counter-clockwise remove the solenoid
adapter.● C ** Clockwise replace solenoid adapter into valve bonnet ● D ** ensuring the o-ring does not become pinched or
damaged.
To use this guide, fold out the back page for visual reference then turn to

- Clockwise tighten the solenoid. B
- Connect one solenoid wire A to the controller common wire and the other solenoid wire to the controller power wire. Tighten and protect using only approved watertight connectors.
Troubleshooting
Valve will not open.
- Ensure main water supply is on. Ensure upstream valves are open. Ensure flow control stem is not
- If valve only opens with manual bleed, ensure controller is programmed to acti- vate the proper zone Test controller power output and service if necessary. Test solenoid power input.
- If controller and solenoid power are detected, insert a thin flat screwdriver into the slotted areas of the solenoid bottom and brown solenoid retainer. Gently pry to disengage Remove plunger assembly and clean debris.
Replace plunger ensuring black surface faces outward. Snap retainer into place ensuring the larger hole faces outward. Persistent problem may be an obstruc- tion lodged in main pipe.
- If power is detected at the control- ler and not the solenoid, inspect and repair damaged lead wires.
Valve will not close.
- Ensure controller is not operating the valve Ensure manual internal bleed is off by clockwise tightening the solenoid adapter. Ensure manual external bleed is off by clockwise tightening the valve bleed screw.
- Turn off water supply and swap solenoid from an operational valve; replace solenoid if
- Turn off water supply and verify that the F1 solenoid adapter o-ring is not damaged; replace if necessary. Check for debris in solenoid bowl preventing plunger from creating a positive seal.
- Check overall system water-pressure requirements and ensure that multiple zone valves are not operating simultane- Disallowing one zone valve to close before another opens can reduce the
