4. Setup and Installation

Proper installation is critical for the effective operation of your UV system. It is highly recommended that installation be performed by a certified plumber or qualified professional.

4.1 Pre-Installation Checks:

• Ensure all components are present and undamaged.
• Verify water quality parameters (e.g., hardness, iron, manganese) meet system requirements. Pre-filtration may be necessary.
• Select a suitable mounting location that is protected from the elements, allows for easy access for maintenance, and is close to a power outlet.

4.2 Installation Steps:

1. Mounting: Securely mount the UV chamber horizontally or vertically using the provided mounting brackets.
2. Plumbing Connections: Connect the water inlet and outlet to the UV chamber. Ensure all connections are watertight.
3. Quartz Sleeve Installation: Carefully insert the quartz sleeve into the UV chamber, ensuring it is centered and sealed with O-rings.
4. UV Lamp Installation: Insert the UV lamp into the quartz sleeve. Connect the lamp connector to the controller.
5. Sensor Installation: Install the UV sensor into its designated port on the chamber. Connect the sensor cable to the controller.
6. Electrical Connection: Connect the controller to a grounded electrical outlet (100-240V, 50-60Hz).
7. Leak Check: Slowly turn on the water supply and check for any leaks.

5. Operating Instructions

Once installed, the Viqua H PLUS system operates automatically to disinfect your water supply.

5.1 Initial Startup:

1. After completing installation and leak checks, plug in the controller.
2. The system will perform a self-diagnostic test. The display will show the remaining lamp life countdown.
3. Allow water to flow through the system for several minutes to purge any air.

5.2 Normal Operation:

• The controller display will continuously show the number of days remaining until the UV lamp requires replacement.
• The integrated UV sensor monitors the UV intensity. If the intensity drops below a safe level, an alarm will sound, and an error message will be displayed.
• If an optional solenoid valve is connected, it will automatically shut off the water flow upon detection of a system error (e.g., low UV intensity, lamp failure) to prevent untreated water from passing through.

6. Maintenance

Regular maintenance ensures the continued effectiveness and longevity of your Viqua UV system. Always disconnect power before performing any maintenance.

6.1 UV Lamp Replacement:

• The amalgam UV lamp has a life expectancy of up to 2 years (approximately 17,520 hours).
• Replace the lamp when the controller indicates the end of its operational life or when an alarm signals low UV intensity.
• Refer to the specific lamp replacement instructions provided with your replacement lamp or on the Viqua website.

6.2 Quartz Sleeve Cleaning and Replacement:

• The quartz sleeve should be cleaned annually or more frequently if water quality dictates (e.g., high hardness leading to scaling).
• Use a soft cloth and a mild acid (e.g., citric acid or vinegar) to remove any mineral deposits.
• Replace the quartz sleeve if it is cracked, scratched, or cannot be cleaned effectively.

6.3 Sensor Maintenance:

• Periodically inspect the UV sensor for any buildup or damage. Clean as necessary following manufacturer guidelines.
