should be conducted annually.
7. Approvals
Integrally piloted valves meet the
requirements of:
1. C-Tick
2. EMC (89/336/CE)

solenoids)
8. 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.
