C
onstruCtion
• All filtration and disinfection components of the
Bio-Logic
®
Pure Water Pack
TM
are conveniently mounted on a single,
stainless steel, mounting bracket.
• The system is designed to mount on a vertical surface, a secure (stud or concrete) wall or a cabinet wall, by the system-
mounting bracket.
• The faucet, supplied with the system, is a low lead, stainless steel faucet, with a hand operated, spring closed lever. The
faucet can be locked in the “ON” position by pushing the lever up locking it against the spout.
• The water purifier’s dual chamber heads are removable and may be rotated independently, which aids in the installation,
maintenance or the retrofitting of an existing system.
• The water purifier’s chamber, and chamber heads are electropolished and passivated type 316 stainless steel.
• EASY-OFF
TM
End Caps enable quick and easy lamp change, without disconnecting the system from the water supply or
draining the purifier. No tools are required.
Always disconnect electrical power when changing lamp.

The
Bio-Logic
®
Pure Water Pack
TM
filter system removes sediment, rust, scale, and particulates, while reducing tastes, odors,
organic chemicals and turbidity. The
Bio-Logic
®
is the ultraviolet disinfection element of the
Pure Water Pack
TM
.
The
Bio-Logic
®
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 operation of the
Bio-Logic
®
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.

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.

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
Turbidity
< 1 NTU
Manganese
0.05 mg/1
Total Suspended Solids
10 mg /1
pH:
6.5 - 9.5
Color:
None
Hardness
6 GPG or 102.6 PPM
Iron
0.3 mg/1
Tannins:
< 0.1 ppm (0.1 mg/l)
UV Transmission
>85% per cm*
* Contact Factory for recommendations on applications where UV transmission is < 85%
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.
