Conditions for Operation

Water quality will impact the performance of your UV system, and the following levels should be utilized as a guideline for pre-treatment requirements of the influent water supply prior to UV treatment:

Iron…………………………………………. < 0.3 ppm (0.3 mg/L)
Turbidity …………………………………. < than 1 NTU
Tannins …………………………………… < 0.1 ppm (0.1 mg/L)
Manganese………………………………. < 0.05 ppm (0.05mg/L)
Hardness ………………………………… < 120 ppm (7 grains per gallon)
UV Transmittance ………………….. > 75%

If you are using untreated surface water or untreated groundwater as your source of supply, the suitability of the water supply for potable applications must be confirmed by the provincial/state and/or local health agency that has jurisdiction.
If the test results indicate that: (1) any of the above contaminant levels are being exceeded, or (2) any prevailing drinking water health standards are not being met, additional pre-treatment options must be installed that will eliminate all contaminants posing health risks. Non-municipal water should be tested on an ongoing basis to ensure treatment efficiency.

Installation Instructions

Accessibility, Orientation & Fittings

Install your UV system in a location that provides ample space for accessing and removing the lamp and quartz sleeve from the UV chamber. A minimum distance equivalent to the length of the UV reaction chamber (stainless steel cylinder) plus 6-12″ (15-30cm) is required to ensure adequate clearance. As the UV system generates heat during use, ensure that no combustible items come into contact with, or are in proximity to the system. It is recommended that you maintain at least 6″ (15 cm) of clear wall space on all sides of the UV for cooling purposes. This will prolong the operating life of the system. Mount electronic controllers where they will not get wet during maintenance or from condensation from copper pipes, etc.

Optional Bypass Line and Drain Valve

The diagram below shows the installation of a typical disinfection system and the optional components that may be used for the installation. The use of a bypass assembly is recommended in case the system requires off-line maintenance. To prevent possible contamination of water in the plumbing, which may pose a health hazard, do not use the bypass line and valve if your source of supply is untreated surface or ground water. If your source of supply is treated municipal water, use of the bypass line and valve will permit uninterrupted water supply in the event of a system malfunction. The installation of a drain valve, while not required, will allow the service technician to drain the system of water prior to conducting any service on the unit.

Horizontal Installation

Optional Vertical Installation

PUR® UV systems may be installed vertically with the outlet port at the top of the system, to eliminate any trapped air, and the inlet port at the base, as shown in the diagram.
Ensure the Controller is kept dry and away from any potential condensation. Use drip loops so moisture does not run down lamp harness or power cord and into the Controller. The Electric Controller must remain dry.
Prior to installation, remove protective caps from inlet and outlet ports of the UV reaction chamber.

System Installation

WARNING: When handling the UV lamps and quartz sleeves, soft gloves or a cloth should always be used to prevent oil deposits on the surface. Oil deposits from your hands can create hot spots on the surface which may lead to premature lamp failure.

Determine a suitable location and ensure mounting of the UV system in the correct orientation can be completed. In order to install/remove the UV lamp and quartz sleeve from the stainless steel chamber, ensure the minimum clearance is double the overall length of the unit.
Attach the mounting clamp to the installation structure using an appropriate screw type for both the weight and material of the surface.
Position the UV reactor chamber into the mounting clamp and secure.
Install all inlet/outlet plumbing to the system (inclusive of all pre-filtration and valve set-ups described above).
NOTE: In order to meet NSF 55 certification the flow restrictor that is included with the UV system must be used to control the flow of water through the UV chamber. The flow restrictor is designed to thread onto either the inlet or outlet ports using Teflon sealing tape for the NPT fittings. In most settings, the system should have a manual shut off valve at the input. The water flows in the direction of the arrow located on the flow restrictor label.
Mount the Electronic Controller in a dry location close to the UV reaction chamber. Install power cord and lamp harness using drip loops to prevent moisture from travelling along cable and into Controller.
Ensure the quartz sleeve is intact and that the o-ring, VuCap® retaining ring and retaining nut are in position and tightened. Do not overtighten the retaining nuts.
Connect the four pins of the UV lamp to the UV lamp plug on the Controller.
Insert the UV lamp into the quartz sleeve and secure the VuCap® protective cover.
Slowly open the supply valves before and after the UV system and ensure there are no water leaks.
Connect the Electronic Controller to the power outlet, and ensure that both the Controller display (indicates lamp life remaining) and the green LED illuminate.
The glow from the UV lamp should also be visible through the VuCap® but note it may not be visible in high ambient lighting.

Your UV disinfection system is now ready for use.
If your system is only being used seasonally, it must be stored properly for the winter.
Disconnect your system from the power source and drain all water from the system.
Before placing the system back in service, disinfection of the household plumbing system is strongly recommended.

In-House Water Distribution System Disinfection

The following procedure is recommended for installations of the UV disinfection system in a whole house treatment application. For systems installed on a municipally treated water system, plumbing system disinfection is at the discretion of the user. To disinfect the distribution system, carry out the following steps. Ensure that the UV system remains on during the entire process.

Familiarize yourself with the various shut-off valves on your system. It is important to understand which combinations of valve positions allow you to isolate the UV system.
Shut off the main water supply, ahead of any filter housing, and depressurize the household water lines.
NOTE: Individual plumbing set-up may vary, so images are included as a visual reference only.
Close the valves necessary to isolate the UV Prefilters.

Remove the filter cartridge closest to the UV. Fill the sump with 1-2 cups of household chlorine bleach (5.25%).
Re-install the sump (without filter) and slowly re-pressurize the system. Open each faucet and allow cold water to run until you can smell chlorine in the water. Shut off the faucet and repeat with all other household faucets including hot water. Be sure to include all exterior faucets, shower heads, and dishwasher/washing machine lines within this process.
Allow the solution to remain in the lines for 30 min tes minimum.
Re-install the pre-filter cartridge, and flush each individual water line as above until no chlorine odor is detected.

It is critical to ensure that the water distribution system is fully flushed of all residual chlorine prior to use. EXTREME CAUTION SHOULD BE EXERCISED as the level of chlorine in the system is approximately 25-50 times greater than that observed in municipally treated water. This is required for the disinfection of the household lines. It is extremely important that proper flushing procedures be followed from all taps prior to use.
NOTE: The introduction of a chlorine disinfection solution to a hot water heater that has been used with untreated hard water or water with excessive iron, manganese or other organic contaminants may lead to oxidization of these materials. If you feel that these conditions may apply to your installation, a thorough flushing of the hot water tank should be done to eliminate the oxidized material from entering the distribution lines.

Operation & Maintenance

The UV system should remain turned on continuously to ensure protection of your water system. During normal operation of the system, the green Controller power LED light will be illuminated and the display will indicate the number of days remaining until lamp replacement is required. During periods of non- use, it is normal for the temperature of the water in the stainless steel chamber to rise. Simply flushing the water line will alleviate this condition. During humid conditions, sweating or small water droplets may be noticed on the surface of the UV reaction chamber. The formation of condensation during high humidity conditions is normal. Do not allow condensation to drip onto the Controller. The following instructions have been provided to assist with general maintenance of the system; UV lamp replacement and quartz sleeve cleaning/replacement. All other system repairs should be completed by a licensed plumber/service technician.
WARNING: Never attempt to service the UV system unless you are an accredited service technician, as the performance of the system could be adversely affected.

Lamp Installation and Replacement

WARNING: The lamp heats up after continuous use and can burn your skin if touched. Disconnect power from the wall outlet and allow lamp to cool for at least 5 minutes before removing. Do not operate the UV lamp outside of the UV Chamber. The lamp in the unit emits powerful Ultraviolet light that can cause permanent damage to skin and eyes. Never look at the lamp when the unit is turned on. Handle the UV lamp by the ends only. Do not touch the glass surface of the UV lamp with your fingers. If the surface of the lamp becomes dirty, use a clean lint-free cloth and isopropyl alcohol to remove any dirt.

Your UV disinfection system is equipped with a visible/audible lamp failure indicator. In the event of UV lamp failure, the red LED light will flash and a beeping sound will be audible from the Electronic Controller of the unit. The lamp life countdown timer will stop decrementing when in alarm mode. Please note that if these conditions occur and you are on a non-municipal supplied water source, you should immediately stop using the water for potable applications until the lamp is replaced and disinfection of all distribution lines is completed.

The ultraviolet lamp has an approximate life of one year (9000 hours). The UV lamp will continue to operate past 9000 hours, however, the UV output decreases rapidly beyond 9000 hours and the UV lamp may no longer provide adequate disinfection of your water supply. The built in 365 day countdown timer displays the number of days remaining until lamp replacement is required. When countdown timer reaches 0 days an intermittent audible alarm will be activated and the Controller display will indicate alarm A3. In order to allow time to obtain a replacement UV lamp, the audible alarm can be silenced for 7 days by pressing and holding button on Controller for 2-5 seconds. After 7 days, alarm will sound again if lamp has not been replaced. This can be done a maximum of 4 times which allows up to 28 days to obtain a replacement UV lamp. After 4 times, the alarm can no longer be silenced until a replacement lamp is installed and the lamp life alarm is reset to 365 days.

Replacement UV lamps and quartz sleeves are available from an authorized dealer. Use only PUR® approved lamps and sleeves to ensure system performance. Replacement lamps and quartz sleeves are sold under the following model numbers:

Allow UV lamp to warm up for a minimum of 2 minutes before flushing water through the UV chamber.

Quartz Sleeve Installation and Replacement

Any mineral deposits or sediment build-up on the quartz sleeve will affect the system performance by decreasing the UV light transmitted through the quartz sleeve into the water column.
The proper maintenance and replacement of the pre-filtration required for the UV system will reduce the accumulation of mineral and sediment residue on the quartz sleeve. The quartz sleeve may be cleaned with a commercially available, non-abrasive, acidic scale remover and a lint free cloth. Cleaning of the quartz sleeve should be done on a regular basis to ensure maximum system performance. The amount of cleaning required will vary depending upon local water conditions and system pre-filtration.
All traces of the cleaning solution must be fully removed from the the quartz sleeve before it is reinstalled in the system. Care should be taken to prevent any cleaning fluid from coming into contact with the inside surface of the quartz sleeve.

Depressurize UV chamber by turning off the inlet water supply and open valve downstream of system. Then close outlet valve.
