3. The Power Switch Light (red) will be lit whenever the N/C
solenoid is open and the PURO PRO system is producing
treated water for the storage tank. At all other times, the
Power Switch Light will be off.
Float Switch Operation:
1. The float switch operates by the orientation of the float. In the
up and vertical or near-vertical position, the electrical circuit is
open, no power is passed, and the inlet solenoid is closed. As
the float is lowered by the water level and reaches just below
the horizontal position, the electrical circuit is closed, power is
passed and the solenoid valve is opened, allowing the Modular
Pro to produce treated water.
2. This function can be tested by holding the float, adjusting the
orientation, and listening for the switch to open and close.
3. For proper functioning, the float requires a stationary axis for
rotation. This can be accomplished by a weight in the float
cable, or by anchoring the float cable just below the intended
fill level for the storage tank.
4. The arc created between the float and the stationary point
determines the range of operation for the Modular Pro from the
ON to the OFF position.
5. Install the float switch so that the OFF position corresponds to
the intended fill level for the storage tank.
