Conditions for Operation
Water quality impacts UV system performance. Recommended influent water quality levels for pre-treatment:
- Iron: < 0.3 ppm (0.3 mg/L)
- Turbidity: < 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 using untreated surface or groundwater, confirm suitability with the local health agency. If test results exceed these levels or do not meet drinking water standards, additional pre-treatment is required. Non-municipal water should be tested regularly.
Installation Instructions
Accessibility, Orientation & Fittings
Install the UV system in a location allowing ample space for accessing and removing the lamp and quartz sleeve. A minimum clearance equivalent to the chamber length plus 6-12" (15-30cm) is recommended. Ensure no combustible items are near the system, as it generates heat. Maintain at least 6" (15 cm) of clear wall space on all sides for cooling. Mount electronic controllers in dry areas, away from condensation.
Optional Bypass Line and Drain Valve
A bypass assembly is recommended for easier maintenance. If using untreated water, do not use the bypass line to prevent contamination. For treated municipal water, a bypass allows uninterrupted supply during system maintenance. A drain valve is optional but useful for draining the system before service.
Horizontal Installation: Shows a typical setup with optional bypass valves, sediment filter, and carbon filter.
Vertical Installation: PUR® UV systems can be installed vertically with the outlet port at the top to eliminate trapped air. Ensure the controller is dry and use drip loops to prevent moisture. Remove protective caps from inlet and outlet ports before installation.
System Installation
WARNING: Handle UV lamps and quartz sleeves with soft gloves or a cloth to prevent oil deposits, which can cause hot spots and premature lamp failure. Do not touch the glass surface of the UV lamp with fingers.
- Determine a suitable location and ensure correct orientation for mounting. Minimum clearance should be double the unit length for lamp and sleeve removal.
- Attach the mounting clamp to the installation structure using appropriate screws.
- Position the UV reactor chamber in the clamp and secure it.
- Install all inlet/outlet plumbing, including pre-filtration and valves.
- NOTE: Use the included flow restrictor to control water flow through the UV chamber. It threads onto inlet or outlet ports using Teflon sealing tape. A manual shut-off valve at the inlet is recommended. Water flows in the direction indicated on the flow restrictor label.
- Mount the Electronic Controller in a dry location near the UV chamber. Use drip loops for the power cord and lamp harness to prevent moisture ingress.
- Ensure the quartz sleeve is intact, and the o-ring, VuCap®, retaining ring, and retaining nut are properly positioned and tightened (do not overtighten).
- 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 supply valves before and after the UV system, checking for leaks.
- Connect the Electronic Controller to the power outlet. Verify the green power LED is illuminated and the controller display shows remaining lamp life. The UV lamp glow should be visible through the VuCap® in low light conditions.
Your UV disinfection system is now ready for use. For seasonal use, disconnect the system from power and drain all water. Disinfect household plumbing before re-connecting.
In-House Water Distribution System Disinfection
This procedure is recommended for whole-house treatment applications. For systems on municipal water, disinfection is at the user's discretion. Ensure the UV system remains on during the process.
- Familiarize yourself with system shut-off valves to isolate the UV system.
- Shut off the main water supply before filter housings and depressurize household lines.
- Close valves to isolate UV pre-filters. Remove the filter cartridge closest to the UV system. 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 run cold water until chlorine is detected. Repeat for all faucets, including hot water, exterior faucets, shower heads, and dishwasher/washing machine lines.
- Allow the solution to remain in the lines for at least 30 minutes.
- Re-install the pre-filter cartridge and flush each water line until no chlorine odor is detected.
CRITICAL: Ensure the water distribution system is completely flushed of residual chlorine. Use EXTREME CAUTION as chlorine levels are 25-50 times higher than municipal water. Proper flushing procedures must be followed.
NOTE: Adding chlorine solution to a hot water heater used with untreated hard water or water with high iron/manganese may cause oxidation. Flush the hot water tank thoroughly if this is a concern.
Operation & Maintenance
The UV system should remain on continuously for water system protection. The green controller power LED indicates normal operation, and the display shows days until lamp replacement. Condensation on the chamber in humid conditions is normal; prevent it from dripping onto the controller. Key maintenance includes UV lamp replacement and quartz sleeve cleaning/replacement. Other repairs should be done by a licensed plumber/service technician.
WARNING: Only accredited service technicians should attempt system maintenance.
Lamp Installation and Replacement
WARNING: The lamp gets hot and can cause burns. Disconnect power and allow the lamp to cool for at least 5 minutes before removal. Never operate the UV lamp outside the chamber. The UV lamp emits powerful UV light that can cause permanent skin and eye damage. Never look directly at the lamp when the unit is on. Handle the lamp only by its ends. Do not touch the glass surface with fingers. Clean with a lint-free cloth and isopropyl alcohol if soiled.
The system has a visual/audible lamp failure indicator (red LED flashes, beeping sound). If a lamp fails, the countdown timer stops. If using non-municipal water, stop using water for potable applications until the lamp is replaced and lines are disinfected.
The UV lamp has an approximate life of one year (9000 hours). While it may continue to operate, UV output decreases significantly after 9000 hours, potentially compromising disinfection. The built-in 365-day countdown timer alerts you to replacement. An intermittent alarm (A3) sounds when the timer reaches zero. The alarm can be silenced for 7 days at a time, up to four times (28 days total), to allow time for replacement.
Replacement UV lamps and quartz sleeves are available from authorized dealers. Use only PUR® approved parts.

Operated in an excessive ambient temperature | Unplug unit until temperature is within ambient operating conditions. | |
Water temperature is too high | Ensure treatment is on cold water side only (prior to heating of water). |
*Water hammer: Sudden closure of a control valve or stopping of a pump produces excessive pressure surges in a pipeline. These pressure surges can cause significant damage to equipment and/or appliances directly attached to the water line. Water hammer is usually noted due to the characteristic banging sounds when valves on the line are suddenly closed. Water hammer conditions must be immediately remedied, and damage to systems as a result of this condition are not covered under warranty.
