INTRODUCTION – DESCRIPTIONS AND DEFINITIONS
You have purchased one of the most technologically advanced Ultraviolet Water Treatment System available anywhere in the world. It has
been designed with you, the consumer, in mind. PURA
®
products are lightweight, easy to use, and simple to maintain. PURA products will
provide you with healthy, clean drinking water for years to come.
WHAT IS ULTRAVIOLET?
Ultraviolet (UV) light from the sun has long been known for its ability
to destroy microorganisms. However, it has only been in recent
years that equipment producing UV light has been manufactured for
residential use.
WARNING: NEVER LOOK DIRECTLY AT A LIGHTED UV LAMP.
ULTRAVIOLET RAYS CAN BE HARMFUL TO EYES.
Activated carbon has been used for hundreds of years to treat
taste, odor, and color problems in water. Activated carbon has been
proven to be an excellent media to produce better tasting water and
to remove harmful water contaminants at a reasonable cost.
Carbon used for lters may be manufactured from wood, coal, or
coconut shells. The raw carbon is ground up and “activated” by

heating the granules at a controlled temperature and pressure.
UV energy is produced by low-pressure mercury vapor enclosed in
a tubular lamp. While a UV lamp resembles a standard uorescent
lamp, it is similar in appearance only.
This process causes the carbon granules to expand and create
active sites where pollutants can be collected by adsorption. These
new sites dramatically increase the total surface area and capacity

of each granule.
microorganisms that can live in water. There are ve major groups of
microorganisms that are altered by a specic spectrum of ultraviolet
light: viruses, bacteria, fungi, algae, and protozoa.
Adsorption is the physical process where certain water pollutants

are attached to the surface of carbon particles as the water ows
When these microbes are exposed to the proper amount of UV
energy, their DNA structure is scrambled, and they are unable to

locked into the carbon granule.
reproduce. Since the cell is now sterile or dead, it is no longer a
threat.
Activated carbon is also able to lter out sediment through a process
of mechanical ltration. The particles are captured in the spaces
between carbon granules.
PURA SYSTEMS
PURA recommends that all UV systems include pre-lters to
process the water before it reaches the UV lamp. This will ensure
that maximum UV exposure is achieved.
PURA UVB, UV20 and UVBB series offers integrated lters in a
single system. These integrated systems use a two-stage ltration
process:
First, a string-wound lter removes the suspended solids that may
shield the microbes and make it difcult to obtain sufcient UV
exposure. Second, an activated carbon lter removes unpleasant
tastes and odors.

PURA Systems are designed to provide complete water treatment in
a compact, easy-to-use package. Please follow the directions in this
Guide exactly when installing your PURA System to ensure that it
operates correctly.
The UV lamp requires a start-up period of one to two minutes in
order to achieve full intensity. Repeated starting of the UV lamp
will shorten its life. Therefore, it is recommended that the UV lamp
remain on at all times during use.

ROUTINE MAINTENANCE
It is important that any water treatment system be properly maintained to ensure consistent water quality. The information provided on this
page is of a general nature. See Cleaning, Disinfecting, and Routine Maintenance Procedure on Page 18 and 19 for detailed information.
Refer to Mounting Bracket and System Plumbing Installation Instructions on Page 1, and the appropriate System Assembly and Activation
Procedures for detailed information to install your specic PURA system.
Cleaning: The inside of the system and the quartz sleeve should be
cleaned each time the lters are changed. Clean all parts (except
the lters and electronic parts) with soap and rinse them thoroughly
with clean potable water. Dry the inside of the quartz sleeve
thoroughly before re-assembling system.
NOTE: Presence of iron or general poor water quality will
require frequent inspection and cleaning.
“O” Rings: Lubricate each “O” ring with a silicone based “O” ring
lubricant to ensure a proper seal.
NOTE: UV lamp should remain on at all times during use
because; repeated starting of UV lamp shortens lamp
life, and UV lamp requires a warm up period of 1-2
minutes.

Filter Replacement: Filters will normally last approximately four to
six months. Filter life will vary due to water conditions. A reduced
ow rate or deteriorating water quality indicates that lters must be
changed.
Use only PURA lters. PURA lters are specially designed to work
in the ultraviolet disinfection process. Use of non-PURA lters voids
the warranty.
CAUTION: Use care when changing the lters to avoid breaking
the quartz sleeve.
UV Lamp Replacement: Lamps must be changed every twelve
months. While UV lamps rarely burn out, they do lose their
disinfection power. Use only PURA UV lamps as they are specically
designed for the PURA system to deliver high quality drinking water.

MOUNTING BRACKET AND SYSTEM PLUMBING INSTALLATION
This Guide covers installation and maintenance of a basic “generic” system. Installer determines conguration of each system and must
adapt these instructions to meet the specic requirements for that conguration. Specic component and assembly information is provided
only for components that are unique to PURA systems. All inter-component connections use standard plumbing components and tools.
INSTALL MOUNTING BRACKET
CAUTION: Do not use any damaged component.
If damage is found, contact your dealer before
proceeding.
1. Unpack boxes and verify that all required components have been
received (see Preparation section for your particular series).
2. Inspect each component for damage.
3. Determine location for installation of the UV system:
a. The PURA UV System should be installed with the sumps
oriented vertically.
CAUTION: The UV system may be installed horizontally, but
the quartz sleeve will be in a position that makes it
susceptible to breakage.
b. Mounting point should allow sufcient room above and
below UV system to service the sumps and UV lamp
without removing the UV system.
The minimum space is:
UVB: 11” (above and below)
UV20, UVBB: 20” (above and below)
UV1: 10” (above and below)
ADDON: 10” or 20” (above) by model
4. For ease of mounting, reduce the weight of the larger systems
by removing the sumps and lters prior to installing the mounting
bracket.
5. Select a location and install the mounting bracket using the
provided screws.
INSTALL SYSTEM PLUMBING
CAUTION: Water pressure must not exceed 75 psig (517 kPa) or
a pressure regulator must be used.
CAUTION: Do not install pump on outlet side of system as
damage to the quartz sleeve may occur. If pump is
required, install it on inlet side of system and verify
output pressure does not exceed 75 psig (517 kPa).
CAUTION: Warranty is void if the unit is used with pressure
exceeding 75 psig (517 kPa). Higher pressures may
damage equipment and may not allow for proper
exposure time with UV lamp or both.
CAUTION: The system will not function properly if water ow is
reversed. See the Exploded Schematic for your model
on the following
1. Turn off source water supply.
CAUTION: PURA recommends using only plastic ttings to
connect the inlet and outlet ports of the PURA system.
Use of metal male ttings inside of plastic female
threaded heads voids the warranty.
CAUTION: Do not over tighten ttings connected to inlet/outlet
ports of the PURA system.
2. Connect inlet of UV system to source water supply using proper
ttings and thread sealing tape.
3. Connect outlet of UV system to water distribution lines using
proper ttings and thread sealing tape.
CAUTION: Do not install clear or translucent tubing on the outlet
side.
