VIQUA UV Water System Owner's Manual

Congratulations on your VIQUA UV Water System!

This ultraviolet (UV) water system utilizes advanced UV technology for trouble-free operation and minimal maintenance. To ensure optimal performance, UV lamps must be replaced annually with genuine VIQUA factory-supplied replacements. VIQUA lamps offer highly efficient and stable UV output over their 9000-hour lifetime. The use of non-genuine lamps can damage the control module, pose safety risks, and void equipment warranty. Without a UV sensor, verifying the UV output of replacement lamps is not possible. Insist on genuine VIQUA replacement lamps for safety and performance.

Why Insist on Genuine VIQUA Replacement Lamps?

• Non-genuine lamps can damage the VIQUA UV equipment's control module.
• Many technical support calls are linked to the use of non-genuine lamps.
• Damage from non-genuine lamps is a safety risk and not covered by warranty.
• Without a UV sensor, UV (invisible) output of replacement lamps cannot be verified.
• Similar appearance or visible blue light does not guarantee equivalent performance.
• VIQUA replacement lamps undergo rigorous performance testing and quality control to ensure safety and performance certifications.

1.2 Safety Precautions:

1.3 Water Chemistry

Water quality is critical for optimal UV system performance. The following levels are recommended for installation:

* If total hardness is less than 7 gpg, the UV unit should operate efficiently with periodic quartz sleeve cleaning. If total hardness exceeds 7 gpg, the water should be softened. If water chemistry exceeds these levels, proper pre-treatment is recommended before UV system installation. Water quality parameters can be tested by a local dealer or private analytical laboratories. Pre-treatment is essential for intended UV system operation.

Section 3: Installation

3.1 UV System Installation

The UV system can be mounted either horizontally or vertically at the point-of-use or point-of-entry, depending on the specific flow rate. If installing the chamber horizontally, the outlet port must point upwards to ensure all air is purged.

Installation Orientation (Figure 2 Description)

The diagram illustrates two valid installation orientations: Vertical and Horizontal. In the Vertical orientation, the UV chamber is positioned upright with the inlet at the bottom and outlet at the top. In the Horizontal orientation, the chamber is laid flat. Both diagrams show the water flow direction and the recommended outlet port position for purging air (upwards for horizontal). The ideal installation is vertical with the lamp connector on top to prevent water damage to lamp pins and connector.

• The controller should be mounted above or beside the chamber, horizontally, to prevent moisture from running down cordage and causing a potential fire hazard. Drip loops in all cordage connected to the controller are highly recommended.
• The complete water system, including any pressure or hot water tanks, must be sterilized before startup by flushing with chlorine (household bleach) to destroy any residual contamination. Refer to Section 3.2.
• The UV system is intended for indoor use only; do not install where it may be exposed to weather.
• Install the UV system on cold water lines only, before any branched lines.
• A 5 micron sediment filter must precede the UV system. Ideally, the UV system should be the last treatment the water receives before it reaches the faucet.

Installation Procedure

1. Typical UV Treatment System (Figure 3 Description): This diagram shows a typical UV system setup with related components. It includes the main water meter shut-off, optional water softener, 5 micron sediment filter, optional carbon filter, the VIQUA UV system, optional solenoid valve, optional drain cock, and various bypass assemblies. Cold water pipes and hot water pipes are indicated. A customer-supplied GFCI circuit is required. The UV system should be the final piece of treatment equipment.
2. Select a suitable location for the UV system and its components, considering GFCI installation. The system can be installed vertically (inlet at bottom) or horizontally. Vertical installation is preferred. Leave enough space to remove the UV lamp and/or quartz sleeve (equal to chamber size).
3. Mount the system to the wall using supplied clamps. Union type connectors are recommended. Install a flow restrictor on the outlet port, ensuring flow matches the indicated direction.

   ⓘ NOTE

   DO NOT solder connections while attached to the system as this could damage the O-ring seals.

   Flow Restrictor (Figure 5 Description): This diagram shows a flow restrictor installed on the outlet pipe of the UV chamber, with an arrow indicating the direction of water flow. An optional temperature management valve is also depicted.

4. Mount the VIQUA ICE controller horizontally to the wall, near the chamber, ideally above it and away from water connections to prevent leaks. Allow for a "drip-loop" on the lamp, sensor, and power cord to prevent water from entering the controller.

   Drip Loop (Figure 6 Description): This diagram illustrates a power cord with a downward loop (drip loop) before connecting to the controller, designed to prevent water from traveling along the cord into the electrical components.

5. Install the UV lamp. Refer to Section 4.1.
6. When all plumbing connections are complete, slowly turn on the water supply and check for leaks. Leaks are often from the O-ring seal. If a leak occurs, shut off water, drain cell, remove retaining nut, wipe O-ring and threads, clean, and re-install.
7. Once no leaks are present, plug the system into the ground fault interrupter and check the controller for proper operation (it should illuminate without alarms).

   ⓘ NOTE

   DO NOT look directly at the glowing UV lamp.

8. Allow water to run for a few minutes to clear air or dust from the chamber.

   ⓘ NOTE

   When there is no flow, the water in the cell will warm up as the UV lamp is always on. To remedy this, run a cold water tap anywhere in the house for a minute to flush out the warm water.

3.2 Cleaning Procedure

It is imperative to chemically clean the entire distribution system after the UV unit is installed, and repeatedly thereafter whenever the UV is shut down, without power, or inoperative. The procedure is as follows:

1. Step 1: Ensure the controller is plugged in for the entire cleaning process.
2. Step 2: Shut off the water supply and close each faucet.
3. Step 3: Remove filter cartridge(s).
4. Step 4: Pour 2 cups of household 5.25% bleach solution into the filter housing(s). Do NOT use Hydrogen Peroxide.
5. Step 5: Re-install the housings. Turn on the cold water supply. Open each faucet and all water openings until bleach is smelled, then close faucets.
6. Step 6: Turn on the hot water supply. Open each faucet and all water openings until bleach is smelled, then close faucets.
7. Step 7: Do NOT use water for 30 minutes. Flush the system until no chlorine smell is detectable and reinstall the filters.
8. Step 8: Reinstall filter cartridge(s).

Section 4: Maintenance

4.1 Replacing UV Lamp

Lamp replacement is a quick and simple procedure requiring no special tools. The UV lamp must be replaced after 9000 hours of continuous operation (approximately one year) to ensure adequate performance.

Procedure:

1. Step 1: Shut off the water line to the chamber and release system pressure before servicing.
2. Step 2: Disconnect the main power source and allow the unit to cool for 10 minutes.
3. Step 3: Remove the lamp connector by squeezing the plastic locking tabs on the side of the connector.
4. Step 4: Remove the lamp in an upward direction from the chamber and lamp connector base. Always hold the lamp at the ceramic ends.
5. Step 5: Insert the new lamp fully into the chamber, leaving about two inches protruding from the chamber.
6. Step 6: Attach the connector to the lamp. Note that the connector only allows correct installation in one position.
7. Step 7: Push the lamp connector against the lamp connector base until an audible click is heard. Re-pressurize the system to check for leaks.
8. Step 8: Hold down the timer reset button and reapply power to the controller until "365" is displayed, then release the timer reset button. A 5-second delay will occur until an audible tone is heard, and the LED display will read "365" again.

4.2 Cleaning and Replacing Quartz Sleeve

Prerequisites:

• Shut off water supply and drain all lines.
• Remove the UV lamp. Refer to Section 4.1.

Procedure:

1. Step 1: Drain the chamber using the drain port.
2. Step 2: Remove the bottom retaining nut, floating spring, and O-ring.
3. Step 3: Remove the top retaining nut and O-ring.
4. Step 4: Remove the quartz sleeve.
5. Step 5: Clean the quartz sleeve with a cloth soaked in CLR, vinegar, or another mild acid, then rinse with water. If the sleeve cannot be cleaned completely or is scratched/cracked, replace it.
6. Step 6: Reinstall the quartz sleeve in the chamber, allowing it to protrude an equal distance at both ends. Slide supplied O-rings onto each end.
7. Step 7: Reinstall the top and bottom retaining nuts, floating spring, and O-rings respectively. Assemble prerequisites in reverse order of disassembly. Plug in controller and verify POWER-ON LED display is illuminated and controller power-up sequence operates.
8. Step 8: Push the lamp connector against the lamp connector base until an audible click is heard. Re-pressurize the system to check for leaks.

4.3 Cleaning and Replacing UV Sensor

Mineral deposits and sediment can accumulate on the sensor window, decreasing detected UV energy. Good maintenance of pre-treatment equipment will reduce residue accumulation. If the system indicates low UV intensity, a stained quartz sleeve and/or sensor window may be the cause.

Prerequisites:

• Remove and clean the quartz sleeve.

Procedure:

1. Step 1: Disconnect the UV sensor from the controller by disconnecting the sensor cable.
2. Step 2: Remove the UV sensor by grasping its body and rotating it counter-clockwise.
3. Step 3: Submerge only the end of the sensor in commercial scale remover for 30 minutes.
4. Step 4: Clean the sensor with a cotton swab and spray with water. Re-insert the UV sensor until a water-tight seal is achieved.

Section 5: Operation

5.1 Basic Systems Incorporating BA-ICE-C and BA-ICE-CL Controllers

5.1.1 Lamp Life Remaining (days)

The controller tracks the lamp's days of operation. The default screen displays the total lamp life remaining (e.g., "365" days). The controller counts down until "0" days, at which point it displays "83" and sounds an intermittent audible chirp (1 second on, 5 seconds off), indicating the need for lamp change.

5.1.2 Understanding your "A3" Code

"83" (DEFERRAL) - When the "A3" or end of lamp life message is shown, the audible alarm can be deferred up to 4 times. Each deferral lasts seven days and is activated by pressing the timer reset button for 5 seconds. Once the final 7-day deferral is reached, the alarm can only be silenced by changing the UV lamp and manually resetting the controller timer (refer to Section 4.1).

5.1.3 Resetting Lamp Life

Refer to Section 4.1.

5.1.4 Total Days of Operation

The controller displays the total running time in days (e.g., "1680"). Press the push-button once to view this. It remains displayed for ten seconds before reverting to the lamp life remaining screen. This value cannot be reset.

5.1.5 Lamp Failure (Blank Screen)

When the system detects UV LAMP FAILURE (no current running through the lamp), the display will be blank, and an intermittent audible tone (1 second on, 1 second off) will sound. This state persists until the condition is remedied.

5.2 Plus Systems Incorporating BA-ICE-CM Controller

5.2.1 UV Intensity (%)

The VIQUA Plus series products incorporate a UV sensor that detects the 254 nm wavelength of the UV lamp. This information is relayed to the controller as "% UV output" (default display). The system displays UV output between 50% and 99%. If the system drops below 50%, a low UV warning ("A2") flashes alternately with the actual UV level (e.g., "49") at 2-second intervals. An intermittent audible tone (2 seconds on, 2 seconds off) also sounds during low UV conditions.

UV Levels Interpretation:

• 65 to 99: System functioning within normal operating range.
• 56 to 64: UV level is still safe, but cleaning or lamp/sleeve replacement may soon be required.
• 50 to 55: UV level is nearing unsafe intensity; UV system should be immediately serviced.
• 49: UV level has reached an unsafe level. Water should not be consumed. The system/water supply should be examined. The solenoid output activates, stopping water flow if a solenoid is installed.

DEFERRAL: To temporarily defer the audible alarm and re-activate the solenoid valve (if fitted) during a low UV alarm, press and hold the timer reset button for five seconds. This mutes the alarm and activates solenoid output for 12 hours.

Over Temperature

When water temperature inside the UV reactor chamber exceeds 40 °C (104 °F), the Controller shows "Ot" on the display. This is usually caused by extended periods of no water flow. To clear, open a faucet and allow water to flow through the system.

Possible causes for low UV alarm conditions:

1. The UV lamp has reached end-of-life (> 9000 hours). Replace with a new lamp of the same size and type.
2. The quartz sleeve and/or sensor window are stained or dirty, possibly due to mineral deposits or sediment not detected in original water analysis. Refer to Section 4.2.
3. Intermittent voltage drop in the household controller reduces lamp output. Lamp returns to normal when power is restored. (Monitoring system will not operate during power failures.)
4. Influent water quality has changed and is no longer within the acceptable operational range. Perform a water analysis.
5. The UV sensor is not installed correctly.

5.2.2 Lamp Life Remaining (Days)

To obtain this reading, press the timer reset button once and follow steps outlined in Section 5.1.3.

5.2.3 Total Days of Operation

To obtain this reading, press the timer reset button twice and follow steps outlined in Section 5.1.3.

5.2.4 Lamp Failure (Blank Screen)

Refer to Section 5.1.5 for explanation.

5.2.5 Solenoid Output

The VIQUA controller provides a powered (line voltage) IEC solenoid output connector, working with the UV intensity monitor. This output is protected by a replaceable 2 amp isolated fuse. Connection to the solenoid can be done using the IEC solenoid power cable PN 260135. When the UV intensity monitor senses that water is not adequately treated (drops to 49% UV intensity or below), the internal relay opens, stopping AC power to the normally closed solenoid valve. The valve remains closed until UV level rises above 49%, then it opens, allowing water to pass. To temporarily enable solenoid output for up to 12 hours, refer to Section 5.2.1.

Solenoid Installation (Figure 7 Description): This diagram shows an optional solenoid valve installed in the water line leading to the UV system, with the VIQUA UV system itself shown vertically. The solenoid valve is positioned before the UV system.

5.2.6 4-20mA Output (Optional)

To transmit UV intensity data remotely via a 4-20 mA signal, an optional "Y" cable (PN 260134) is available from dealers. The "Y" cable comes with 20 meters (65') of cable for the 4-20 mA signal.

Procedure:

1. Step 1: Disconnect the existing sensor cable from the controller.
2. Step 2: Connect the 'Y' cable to the controller.
3. Step 3: Attach the "male" end of the removed sensor cable to the "female" end of the new "Y" cable. Appropriately attach the 4-20 mA cable to the applicable equipment and ensure all connections are hand-tighten.
