Setting Fill Set Point
• Pressing the “Up” arrow button accesses the fill set point.
The “Fill” set point terminates the filling of the secondary
tank when the pressure of the secondary tank is between
80 and 130 psi
• If the pressure is above 130 psi during the fill, the fill is
terminated at the “Fill” set point -1 5” This allows for the
liquid growth due to an increased saturation level
• If the pressure is below 80 psi the fill is terminated at the
“Fill” set point +1 5” Colder liquid takes up less volume
Adding to the fill set point will assure that the PB time
will be consistent
• Pressing and holding the “Up” arrow and pressing the “+”
button or the “-” button will adjust the set point
Setting Bulk Tank Critical Pressure
Note: Since the tanks are warm upon initial
installation, they may vent for several
minutes before they are cold enough to
accumulate liquid.
• Pressing the “Down” arrow button accesses the Bulk
Critical set point If the storage (bulk) tank is above the
“BC” set point during the filling of the secondary tank,
the secondary tank will vent to atmosphere to minimize
the heat added back to the storage tank
• If the storage tank pressure is below the “BC” set point
the secondary tank will fill in the “Low Loss” fill mode.
• The “Low Loss” fill mode cycles the vent to atmosphere
valve to minimize losses The current “Bulk” pressure is
also displayed on this screen
• Pressing and holding the “Down” arrow and pressing the
“+” button or the “-” button will adjust the set point
