815installThe 815 is installed outside the tank by piping the chamber’s upper and lower 1” NPT ports into the tank wall, thus allowing the liquid level to enter the chamber. The customer -furnished supply piping from the main valve connects to the 3/8” NPT inlet port of the pilot. Minimum recommended size for this line is 1/2” OD tubing or 3/8” pipe. The 3/8” exhaust port is piped back to the discharge of the main valve.
