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 valve to inlet pipes and blowtube to valve, tighten dresser nut. 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.
