Hunter G835 - Inlet Valve Service and Installation; Valve Identification

INLET VALVE REMOVAL, SERVICE AND INSTALLATION
Caution! Electric valve-in-head rotors are connected to pressurized main-line or sub-main piping. This pressurized
piping must be depressurized before servicing the inlet valve. Serious bodily injury can occur if valve is removed
when the piping is pressurized. Keep head and body parts away from the rotor’s exposed internal openings at
all times. Wear proper eye protection and use the designated tools when servicing these rotors.
ToolS needed (VARieS WiTH RoToR Model)

It is important to note that there are different types of inlet valves (also commonly known as foot valves). If the incorrect
inlet valve is installed, the rotor will malfunction. Hunter has a color-coding system to help correctly identify these valves:
G800C Check-O-Matic Rotors = Black screen attached to valve (g 72)
G800E Electric V.I.H. Rotors = Tan screen attached to valve (g 73)
G900C Check-O-Matic Rotors = Black screen attached to valve (g 74)
G900E Electric V.I.H. Rotors = White screen attached to valve (g 75)
