Replacing the Meter Turbine and Sensor Assembly
• Disconnect the power cord from the back of the control and place the
system on bypass.
• Remove the rear cover and depress the brine stem to relieve the water
pressure (
see Figure 16 on page 33
).
• Remove the piston guide screw, control head mounting screws, and
control head (
see Figures 16 and 17on page 33
).
• Remove the screws and mounting clips (
see Figure 23
).
• Using a screwdriver, gently pry the meter turbine from the valve (
see
Figure 23
).
• To verify that the turbine meter is not restricted, blow through the inlet
side (
see Figure 24A
) of the meter turbine assembly. The meter turbine
should spin without restraint. If the meter turbine does not spin, please
proceed to the next step.
• To access the inside of the meter turbine, unscrew the inlet side of the
turbine (
see Figure 24A
), remove the components (
see Figure 24B
), and
check for damage or debris.
• Lubricate all 4 O-rings with a silicone-based lubricant and reverse the
procedure for reassembly.
