2. Informazioni sulla sicurezza
WARNING: Ultraviolet (UV-C) radiation is harmful to skin and eyes.
- Non guardare mai direttamente un UV illuminato lamp. Direct exposure can cause severe eye damage (photokeratitis).
- Avoid direct exposure of skin to UV radiation. UV-C light can cause skin burns and increase the risk of skin cancer.
- Ensure the UV system is completely powered off and disconnected from the electrical supply before attempting any installation, replacement, or maintenance.
- Handle the bulb by its base or ends to avoid touching the glass, as oils from your skin can reduce its effectiveness and lifespan.
- Dispose of used bulbs according to local regulations for fluorescent lamps, as they contain mercury.
- Tenere fuori dalla portata dei bambini.
Always follow the safety guidelines provided by the manufacturer of your UV system (e.g., VIQUA UVMAX C4 system) when installing or replacing this bulb.
3. Installazione
Follow these steps to safely install the Technical Precision Replacement UVMAX C4 Light Bulb into your compatible UV system.
- Disconnessione dell'alimentazione: Locate the power source for your UV system and completely disconnect it. This is a critical safety step to prevent electrical shock and UV exposure.
- Raffreddare: Allow the existing UV lamp to cool down completely before handling.
- Rimuovere la vecchia lampadina: Carefully remove the old UV lamp from its socket. Refer to your UV system's original manual for specific instructions on how to safely remove the lamp and quartz sleeve (if applicable).
- Inspect Quartz Sleeve (if applicable): If your system uses a quartz sleeve, inspect it for cracks or damage. Clean the quartz sleeve with a soft cloth and a mild cleaning solution if it appears dirty or has mineral deposits. Ensure it is completely dry before reinstallation.
- Installare una nuova lampadina: Gently insert the new Technical Precision Replacement UVMAX C4 Light Bulb into the lamp socket. Ensure the pins align correctly with the socket. Do not force the bulb. Handle the bulb by its ceramic ends or plastic base, avoiding contact with the glass tube.

- Sostituzione della lampadina: The average lifespan of this UV bulb is approximately 10,000 hours of operation. It is recommended to replace the bulb annually, even if it appears to be working, as its UV-C output diminishes over time. Refer to your UV system's manual for specific replacement schedules.
- Pulizia del manicotto di quarzo: If your system uses a quartz sleeve, it should be cleaned periodically (e.g., every 3-6 months) to remove any mineral deposits or fouling that can block UV light transmission. Always disconnect power before cleaning.
- Disposizione: When replacing the bulb, dispose of the old bulb responsibly according to local hazardous waste regulations, as it contains small amounts of mercury.
