SECTION 1: Safety Instructions
WA R N I N G
During extended periods of no water ow, the water in your chamber
may become very hot (Approx. 140 °F, 60 °C) and can potentially lead to
scalding. It is recommended to run your water until very hot water has
been purged from the systems chamber. DO NOT allow water to contact
your skin during this time. To eliminate this condition, a temperature
management valve can be installed at the outlet of your UV system.
DO NOT pass water through the UV system for a minimum of 10
minutes after connecting and applying power (including after power
interruptions). This will avoid passing under-treated water that may,
in rare instances, pose health hazards.
The system contains a Germicidal UV Lamp. DO NOT operate the UV
Lamp when it is removed from the chamber. Unintended use or damage
of the system may result in the exposure of dangerous UV radiation. UV
radiation may, even in small doses, cause harm to the eyes and skin.
Changes or modications made to this system without the consent of
the manufacturer may render the system unsafe for operation and will
void the manufacturer's warranty.
CAUTION
Failure to follow these instructions could result in minor or moderate injury.
Carefully examine the disinfection system after installation. It
SHOULD NOT be plugged in if there is water on parts not intended
to be wet such as, the ballast controller or lamp connector.
Due to thermal expansion concerns and potential material degradation
due to UV exposure, it is recommended to use metal ttings and at least
10" of copper pipe on the outlet of your UV chamber.
Hg EXPOSURE: The UV lamp contains mercury. If the lamp breaks, avoid
inhalation or ingestion of the debris and avoid exposure to eyes and
skin. NEVER use a vacuum cleaner to clean up a broken lamp as this may
scatter the spilled mercury. Obey local regulations and guidelines for
the removal and disposal of mercury waste.
NOTICE
The UV lamp inside the disinfection system is rated at an eective
life of approximately 365 days or 9000 hours. To ensure continuous
protection, replace the UV lamp annually.
The UV system is NOT to be used or played with by children. Persons
with reduced physical, sensory or mental capabilities, or people who
lack of experience and knowledge, are also NOT to handle the UV
system unless they have been given supervision or instruction.
This system is intended to be permanently connected to the water lines.
This system is NOT intended to be used in or above water or outdoors or
used in swimming pools when persons are in the pool.
EXTENSION CORDS: If an extension cord is necessary, use only 3-wire
extension cords that have 3-prong grounding type plug and 3-pole cord
connectors that accept the plug from this system. Use only extension
cords that are intended for outdoor use. Use only cords having an
electrical rating not less than the rating of the system. A cord rated for
less amperes or watts than this system rating may overheat. Exercise
caution when arranging the cord so that it will not be tripped over or
pulled. DO NOT use damaged extension cords. Examine extension cord
before using and replace if damaged. DO NOT abuse extension cord.
Keep extension cord away from heat and sharp edges. A extension
cord from the receptacle before disconnecting this system from
the extension cord. Never yank cord to pull plug from outlet. Always
ground the plug into an appropriate outlet that is properly installed
and grounded in accordance with all local codes and ordinances.
1.3 WATER CHEMISTRY WATER QUALITY
Water quality plays an extremely important role in
the transmission of germicidal ultraviolet rays. It is
recommended that the water does not exceed the
following maximum concentration levels.
MAXIMUM CONCENTRATION LEVEL
Iron < 0.3 ppm (0.3 mg/L)
Hardness* < 7 gpg (120 mg/L)
Turbidity < 1 NTU
Manganese < 0.05 ppm (0.05 mg/L)
Tannins < 0.1 ppm (0.1 mg/L)
Uv transmittance
> 75% (call factory for
recommendations on
applications where UVT < 75%)
Eectively treating water with higher concentration
levels than listed above can be accomplished,
but may require added measures to improve water
quality to treatable levels.
UV DOSE
The units generate a UV dosage of at least 30,000
microwatt-seconds per square centimeter (µW-s/cm2),
even at the end-of-lamp life (EOL), which is more than
sucient to destroy most waterborne microorganisms,
such as bacteria, yeasts, algae, etc.
* Where total hardness is less than 7 gpg, the UV unit should operate eciently provided
the quartz sleeve is cleaned periodically. If total hardness exceeds 7 gpg, the water should
be softened. If your water chemistry contains levels in excess of those mentioned above,
proper pre-treatment is recommended to correct these water problems prior to the
installation of your UV disinfection system. These water quality parameters can be tested
by your local dealer, or by most private analytical laboratories. Proper pre-treatment is
essential for the UV disinfection system to operate as intended.
