To guard against injury, basic safety precautions should be observed, including the following:
READ AND FOLLOW ALL SAFETY INSTRUCTIONS.1.
DANGER – To avoid possible electric shock, special care should be taken since water is employed in the use of this system. Unless a 2.
situation is encountered that is explicitly addressed by the provided maintenance and troubleshooting sections, do not attempt repairs
yourself; refer to an authorized service facility.
CAUTION - Do not operate with broken or faulty parts as this may result in exposure to ultraviolet radiation. Contact supplier for 3.
replacement parts.
Do not operate the system if it has a damaged cord or plug, or if it is malfunctioning or if it has been dropped or damaged in any manner.4.
Always unplug the system, shut off water flow and release water pressure before servicing or cleaning. Never yank cord to remove from 5.
outlet; grasp the wall plug and pull to disconnect.
Do not use the system for other than intended use. The use of attachments not recommended or sold by the manufacturer may cause an 6.
unsafe condition.
To prevent risk of electrical shock, connect this system only to a properly grounded, grounding-type power supply receptacle that is 7.
protected by a Ground Fault Circuit Interrupter (GFCI). Inspect performance of GFCI as per manufacturer’s suggested maintenance
schedule. If an extension cord is used, ensure it is of a sufficient rating and accepts the plug from this system; never use an adapter.
Visually inspect this system prior to installation. If the quartz sleeve or lamp is broken, cracked or damaged in any way, do not use. 8.
Contact the supplier for replacement parts.

This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to
reduce the risk of electrical shock. This system is equipped with a cord having an equipment-grounding conductor and a grounding plug. The
plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
DANGER – Improper connection of the equipment-grounding conductor can result in a risk of electrocution. Check with a qualified electrician
or service personnel if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with this system – if it
will not fit the outlet, have a proper outlet installed by a qualified electrician. Do not use any type of adapter with this system.

To comply with the National Electrical Code (NFPA 70) and to provide additional protection from the risk of electric shock, this system should
only be connected to a properly grounded, grounding-type power supply receptacle that is protected by a Ground Fault Circuit Interrupter
(GFCI). Inspect operation of GFCI as per manufacturers suggested maintenance schedule.

If an extension cord is necessary, use only 3-wire extension cords that have 3-prong grounding-type plugs and 3-pole cord connectors that
accept the plug from this system. Use only extension cords that are intended for outdoor use. Use only extension 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. Always disconnect the
extension cord from the receptacle before disconnecting this system from the extension cord. Never yank cord to pull plug from outlet. Always
grasp the plug and pull to disconnect.
WARNING – To prevent risk of electrical shock, connect this system only to a properly grounded, grounding-
type power supply receptacle that is protected by a Ground Fault Circuit Interrupter. Pull plug before
servicing or replacing lamp. Keep all connections dry and off the ground. Do not touch plug with wet hands.
WARNING – Read manual before installing or servicing this system. Only authorized personnel possessing a
strong understanding of this system should attempt to replace lamp or service this system.
WARNING – Do not look directly at UV lamp when it is operating. The light emitted by the lamp will cause
serious eye damage and burn unprotected skin.
NOTE – Maximum pressure rating is 125 PSI (8.62 bar)

Sample valve: Allows for sampling of raw water.
Shut-off valve: Required to allow maintenance of pre-treatment equipment.
Pre-treatment (illustrative only): For the UV system to operate effectively, the water should meet certain
water quality parameters, as outlined below. To meet these, pre-treatment of the water may be required. Pre-
treatment equipment must be installed BEFORE the UV chamber. Pre-treatment systems can be comprised of
one or more of the following elements: sediment filters; carbon filters; iron removal systems; water softeners;
cyst reduction filters, etc.

UV systems disinfect the water using ultraviolet light, treating the water as it passes through the system. When
there is a risk that water downstream of the UV system has been contaminated, it is critical that these water lines
be chemically disinfected. Disinfection of the water lines is therefore required after initial system installation and
following any period of time during which the system is inoperative, whether due to an alarm condition, a power
failure, or for any other reason. Make sure the UV system is on during the entire disinfecting process.

In some cases, short-term flows of low ultraviolet transmittance (UVT) water can be created following 1
and during the regeneration cycle of a water softener, resulting in a sensor alarm. Flushing the UV system
alleviates this condition until the softener goes through another regeneration cycle. In the longer term,
the softener's settings must be modified. To flush the UV system, disinfect the water lines following the
procedures outlined under "Disinfecting The Water Lines" in the Installation section.
Plus models are equipped with a unique, patented, self-test sensor. Simply press the test button located at 2
the top of the sensor and hold until the audible alarm stops (usually about 5 seconds). If the audible alarm is
still present after 30 seconds, release the button and replace the sensor.

Sleeve cleaning
Minerals in the water slowly form a coating on the sleeve. This coating must be removed because it reduces the
amount of UV light reaching the water, thereby reducing purification performance.
Basic models: please clean the sleeve regulary (3-4 times per year, or more often depending on water quality).
Plus models: the need to clean the sleeve will be indicated by a low UV alarm (flashing red indicator light beside
the sensor on control panel - see Control Panel section for details).
When only cleaning is required, follow instructions and re-install the current lamp.
Lamp replacement
The amount of UV light created by the lamp decreases over time, requiring that the lamp be replaced every 12
months. NOTE: The UV system is designed to operate continuously and should not be shut off for short periods
of time, such as over a period of less than three weeks.
A, B4, C4 Models: Please keep track of your lamp's life. After 12 months follow these instructions to replace
system with a new lamp.
D4, E4, F4 and Plus Models : The system will automatically notify you after 12 months to replace the lamp.
Follow these instructions.
Equipment required:
Cloth must be
soft, lint-free, and
chemical-free. No
clean-wipes.
Scale remover
such as CLRTM or
Lime-AwayTM.
Cottom swab.
(For Plus models only)
