Float valve system
DI/RO water systems (except for steam injection) use a float valve
system to control water levels for optimum operating efficiency.
DI/RO systems are used where water/steam purity is important,
where demineralized water is needed to improve performance or
lessen maintenance requirements, or where a potable water source
has minimal or no conductivity, thus requiring a float rather than a
probe to sense water levels.
The float valve system consists of a fill float and a low water cutoff
float.
The fill float regulates how much water is added to the tank via a
float ball, float arm, and mechanical valve. The valve is adjusted to
fill the evaporating chamber within ¼" (6 mm) of the overflow port
allowing heated, and therefore expanded, water at startup to fill the
external P-trap.
The low water cutoff float has an electrical switch that closes
when a ready water condition is reached. A low voltage
(0–2.3 VAC) current runs from the Vapor-logic
3
controller to the
switch allowing the controller to sense a ready water condition. This
float switch provides low water protection for the heating outputs. If
the water falls below the float, the heating outputs are disabled.
Vapor-logic
3
uses the same three-second delay that is used with
the probe system to determine whether water is in contact with the
float.
CAUTION:
Damage caused by chloride corrosion is not covered by your
DRI-STEEM warranty.
