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.
UV energy is produced by low-pressure mercury vapor
enclosed in a tubular lamp. While a UV lamp resembles a
standard fluorescent lamp, it is similar in appearance only.
Energy produced by the UV lamp has the ability to destroy
microorganisms that can live in water. There are five major
groups of microorganisms that are altered by a specific
spectrum of ultraviolet light: viruses, bacteria, fungi, algae, and
protozoa.
When these microbes are exposed to the proper amount of UV
energy, their DNA structure is scrambled, and they are unable
to reproduce. Since the cell is now sterile or dead, it is no
longer a threat.
WHAT IS ACTIVATED CARBON?
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 filters 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.
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.
WHAT IS ADSORPTION?
Adsorption is the physical process where certain water
pollutants are attached to the surface of carbon particles as the
water flows through the filter. The pollutants are removed from
the water and locked into the carbon granule.
Activated carbon is also able to filter out sediment through a
process of mechanical filtration. The particles are captured in
the spaces between carbon granules.
PURA SYSTEMS
PURA recommends that all UV systems include pre-filters 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 filters in
a single system. These integrated systems use a two-stage
filtration process:
First, a string-wound filter removes the suspended solids that
may shield the microbes and make it difficult to obtain sufficient
UV exposure. Second, an activated carbon filter removes
unpleasant tastes and odors.
PURA Ultraviolet Water Treatment Systems are designed for
indoor use only.
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 14 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 specific PURA system.
Cleaning: The inside of the system and the quartz sleeve
should be cleaned each time the filters are changed. Clean
all parts (except the filters 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 flow rate or deteriorating water
quality indicates that filters must be changed.
Use only PURA filters. PURA filters are specially
designed to work in the ultraviolet disinfection process.
Use of non-PURA filters voids the warranty.
CAUTION: Use care when changing the filters 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 specifically designed for the PURA system
to deliver high quality drinking water.

The system must be installed in accordance with applicable city, country, and local plumbing codes.
PURA products are designed to provide years of trouble-free service if properly maintained.
Retain these instructions for future reference.
MOUNTING BRACKET AND SYSTEM PLUMBING INSTALLATION
This Guide covers installation and maintenance of a basic “generic” system. Installer determines configuration of each
system and must adapt these instructions to meet the specific requirements for that configuration. Specific 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 sufficient 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 filters
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
flow is reversed. See the Exploded
Schematic for your model on the following
pages to ensure proper flow direction.
1. Turn off source water supply.
CAUTION: PURA recommends using only plastic
fittings to connect the inlet and outlet ports of
the PURA system. Use of metal male
fittings inside of plastic female threaded
heads voids the warranty.
CAUTION: Do not over tighten fittings connected to
inlet/outlet ports of the PURA system.
2. Connect inlet of UV system to source water supply
using proper fittings and thread sealing tape.
3. Connect outlet of UV system to water distribution
lines using proper fittings and thread sealing tape.
4. See appropriate System Assembly and Activation
Procedures for your system to complete installation.

2. Remove Quartz Sleeve (Item 17) from packing tube.
While holding middle of quartz sleeve with one hand, slide
protective bag with other hand to expose open end.
3. Place a small amount of silicone based “O”ring lubricant
on the outside of the open end of the quartz sleeve only
on the area that will engage with the “O”ring.
CAUTION: Apply even pressure to push the quartz sleeve
into Quartz Adapter Sleeve (Item 4). To avoid
breakage, make sure quartz sleeve goes in
straight by pushing it with a slight twisting motion.
4. Insert quartz sleeve into quartz adapter sleeve until the top
of red tape meets the bottom of the quartz adapter sleeve.
NOTE: Quartz Adapter Sleeve (Item 4) is factory
installed into the UV Head (Item 5).
5. Remove Red Tape (Item 23) and protective bag from
quartz sleeve.
NOTE: Wipe all fingerprints and excessive lubricant
from quartz sleeve with isopropyl alcohol.
