Optional Electric Water Level Control Package
As an option, an electric water level control package is available in lieu of the mechanical
make-up assembly. The package consists of a probe-type liquid level control assembly and a
slow-closing solenoid valve. Stainless steel electrodes, factory-set at predetermined lengths,
extend from an electrode holder into the cold water basin. For more information, refer to the
Universal Electric Water Level Control Installation, Operation & Maintenance Manual For Part
number 313555 available at BaltimoreAircoil.com.
• Clean the stainless steel electrodes periodically to prevent accumulations of scale,
corrosion, sludge, or biological growth, which could interfere with the electrical
circuit.
• The water level is maintained at the recommended operating level regardless of the
system thermal load. Therefore, it is not recommended that the operating level be
adjusted.
• During the start-up of units equipped with the electric water level control package,
bypass the control unit in order to fill the unit to the overflow connection.
