Congratulations on the purchase of your ultraviolet (UV) water disinfection system!
This system is designed to provide you with years of trouble-free operation and
minimal maintenance required.
To ensure ongoing disinfection of your water, replace UV lamp annually.
Why should you insist on genuine factory supplied Pentair replacement lamps?
• Use of widely available, non-genuine, replacement lamps has been shown to
damage the control module of Pentair UV disinfection equipment.
• An increasing number of calls to Pentair Technical Support are connected with non-
genuine lamps being used (unknowingly) as replacements.
• Damage arising from the use of non-genuine lamps poses a safety ris
k and is not
covered by equipment warranty.
• Unless the UV equipment is equipped with a UV sensor (monitor), it is not possible to
verify the UV (invisible) output of replacement lamps.
• Similar appearance to the original lamp and the presence of (visible) blue light does
not mean equivalent disinfection performance.
• Pentair replacement lamps undergo rigorous performance testing and strict quality
control processes to ensure that the safety and performance certifications of the
original equipment are not compromised.
So, you can see that it's simply not worth the risk! Insist on genuine Pentair
replacement lamps.

1.2 Safety Precautions:
DANGER
Failure to follow these instructions will result in serious injury or death.
• Electric Shock: To avoid possible electric shock, special care should be taken sin ce water is present near the electrical equipment. Unless a
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.
• GROUNDING: 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.
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 does not fit in
the outlet, have a proper outlet installed by a qualified electrician. DO NOT use any type of adapter with this system.

Safety Information
Hg
• During extended periods of no water flow, the water in your chamber can become very hot (Approx. 60 °C) and potentially lead to scalding. It is
recommended to run your water until this hot water has been purged from your 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.
• This system contains a 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 little doses, cause harm to the eyes and skin.
• Changes or modifications made to this system without the consent of the manufacturer could render the system unsafe for operation and may void
the manufacturer's warranty.
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
controller or lamp connector.
• Due to thermal expansion concerns and potential material degradation due to UV exposure, it is recommended to use metal fittings 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, then 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.
• The UV lamp inside the disinfection system is rated at an effective life of approximately 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 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 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.
• If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent.
• SYSTEM PROTECTION: To protect your Controller, a UL1449 certified (or equivalent) transient voltage surge suppressor is strongly
recommended.
• The UV lamp in this system conforms to the applicable provisions of the Code of Federal Regulations (CFR) requirements including, Title 21,

Section 3 Installation
3.1 UV Disinfection System
Electronic controller must be connected to a Ground Fault Protected Circuit (GFCI) receptacle and the lamp connector ground wire connected to the
stainless steel chamber.
The disinfection system is designed to be mounted either horizontally or vertically at the point-of-use or point- of- e ntr y
depending on the specific flow rate of the unit.
Note: Install vertically with the lamp connector on top to prevent water damage from occurring on the lamp pins and lamp
connector.
• The controller should be mounted either above or beside the chamber. Always mount controller horizontally to prevent
moisture from running down cordage and causing a potential fire hazard. (Figure 5)
• The complete water system, including any pressure or hot water tanks, must be sterilized before start up by flushing
with chlorine (household bleach) to destroy any residual contamination. (Section 3.2)
• For indoor use only.
• Install the disinfection system on cold water line only, before any branched lines.
• A 5 micron sediment filter must precede the disinfection system. System should be the last treatment the water
receives before it reaches the faucet.
CAUTION
Procedure:
1. (Figure 2) shows the installation of a typical disinfection system and the related components that may be used for the
installation. The use of a bypass assembly is recommended in case the system requires offline maintenance. In this
case, note that the system requires a supplementary disinfection for the distribution system if any water is used during
by-pass condition. In addition, during by-pass, the water will NOT be disinfected and a “DO NOT CONSUME THE
WATER” tag should be physically installed on the by-pass assembly until such time as the system is sanitized and
returned to service. For more information, refer to Section 3.2. If the water is to be consumed while the system is offline, the water must be boiled for twenty minutes prior to consumption.
