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.
• 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 ll the unit to
the overow connection.
