Maintenance
Before conducting any maintenance activity on the system ensure that components are fully isolated from pressure and power supplies. Pressure
 and power should not be reapplied until the valve has been fully assembled. Diaphragm and pilot inspection should be conducted annually.

Installation
For your safety do not pressurise system until all valves and pipes are fully
secured. Do not attempt to remove a fitted valve while system is under pressure.
1. Prepare supply and blowtube pipes* to suit valve specification. Avoid installing
valves underneath the tank.
2. Ensure tank and pipes are free from dirt, rust or other particulate.
3. Ensure supply air is clean and dry.
4. Mount valves to inlet pipes and blowtube to valves, tighten dresser nuts.
5. Tanks and pipes must be independently restrained from valve.
6. Make electrical connections to solenoid or connect RCA pilot port to pilot valve
(RCA valves only).
7. Apply moderate pressure to system and check for installation leaks.
8. Fully pressurise system.
9. Test fire and listen for proper actuation and crisp pulse noise.
Valve is not a structural component. Do not rely on valve to retain tanks or pipe.

*Pipes must be to Schedule 40 outside diameter
