Note: The gauge must indicate a minimum pressure greater than 8 psi
when valve 41 is open. If not, the treated water supply may not meet
specifications for flow and pressure.
8. Tighten the lock nut and verify the peak pressure is still between 18 and 20 psi
on the gauge.
9. Turn the machine Off, turn off the source water supply, remove the gauge
and reconnect the tubing using clamps to prevent leaks.
10. Turn the treated water supply source On, turn the machine On and select
