4. For the inlet solenoid to open, two conditions must be met: The
power box switch must be in the ON position, and the float
switch must be in the vertical (tank not filled) position. If either
of these conditions is not met, the inlet solenoid will remain
closed.
5. The normal operating condition is for the power box switch to
be in the ON position. In this condition, the solenoid will open
and allow the PURO PRO to treat inlet water only when the
storage tank is not full (the float switch is in the vertical
position). Whenever the storage tank is full (the float switch is
in the horizontal floating position), the solenoid will be closed.
PURO PRO Power Switch Operation:
1. The power switch has an ON and OFF switch position to
indicate whether 120 VAC power is being applied to the PURO
PRO system.
2. In the OFF position, no power is being applied to the N/C
solenoid, and the system will not operate. In the ON position,
power is being applied to the PURO PRO system. However,
the N/C solenoid will only open, and the PURO PRO system
will only produce treated water when the float switch is in the
vertical (Tank-not-full) position.
