ONSTRUCTION
• The water purifier is designed to mount horizontally.
• A drain port on the chamber aids in draining of the purifier.
• The water purifier chamber is passivated and electropolished type 316 Stainless Steel.
• The ballast housing is a combination of Stainless Steel Type 304 and Aluminum Alloy.
• Coated chambers are available for uses with special applications, consult Factory.
• Easy-off end caps allow for quick and easy lamp change, without disconnecting from the water supply or draining
the purifier. No tools are required.

RINCIPLE OF
O
PERATION
The MightyPure
™ 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 MightyPure
™ is as follows:
1. Water enters the purifier and flows into the annular space between the quartz sleeve and the chamber wall.
2. Suspended microorganisms are exposed to the ultraviolet rays emitted by the germicidal lamp.
3. The translucent sight port, or optional ultraviolet monitor, provides visual indication of germicidal lamp operation.
4. Water leaving the purifier is instantly ready for use, no further contact time is required.
L
IMITATION OF
U
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.
W ATER Q 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:
Table 1 - 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.
