RINCIPLE OF
PERATION
The MINIPURE
design has been carefully conceived to provide adequate germicidal dosage throughout the disinfection
®
chamber. The dosage, as it applies to ultraviolet disinfection, is a function of time and the intensity of ultraviolet radiation to
which the water is exposed. The exposure time, in seconds, is the total time it takes the water to flow through the disinfection
chamber exposing it to the germicidal lamp. Exposure time is related to the flow rate; the higher the flow rate, the lower the
exposure time or the lower the flow rate, the higher the exposure time. The ultraviolet intensity is the amount of energy, per unit
time, emitted by the germicidal lamp. The dosage is the product of ultraviolet intensity and the exposure time. The operation of
the MINIPURE
is as follows:
®
•
Water enters the purifier and flows into the annular space between the quartz sleeve and the chamber wall.
•
Suspended microorganisms are exposed to the ultraviolet rays emitted by the germicidal lamp.
•
The LED indicator light, located on the ballast, provides visual indication of germicidal lamp operation.
•
Water leaving the purifier is instantly ready for use, no further contact time is required.

IMITATION OF
SE
The water purifier is intended for the use with visually clear water, not colored, cloudy or turbid. See "Water Quality" section
below. The water purifier is NOT intended for the treatment of water that has an obvious contamination or intentional source,
such as raw sewage; nor is the unit intended to convert wastewater to microbiologically safe drinking water.

UALITY
Water quality plays a major role in the transmission of germicidal ultraviolet rays. It is recommended that the water does not
exceed the following maximum concentration levels:
Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added
measures to improve water quality to treatable levels. If, for any reason, it is believed the ultraviolet transmission is not
satisfactory, contact the factory.
