The UVC lamp was not pre-installed and must be inserted into the unit head before reattaching it. Refer to 'Cleaning the quartz glass / Replacing the UVC lamp'.
Installing the Unit
- Install the unit at least 2 m from the edge of the pond.
- Only install the unit in permitted positions to ensure fault-free operation.
- Allow sufficient space for carrying out maintenance work.
Diagram description: Shows the unit positioned at least 2 meters from a pond edge. Illustrates permitted and non-permitted installation orientations (e.g., horizontal, vertical) for different Vitronic models, indicated by checkmarks (✔️) and crosses (❌).
Establishing the Connections
- Use hoses suitable for a pressure of at least 1 bar.
- Shorten the stepped hose adapters according to the hose diameter in use.
- Secure the hose with a hose clip.
- Hand-tighten the union nut of the stepped hose adapter.
- Screw the stepped hose adapter with the flat seal or O-ring onto the connection to ensure it is leak-tight.
- You can choose from the two connections arranged opposite each other to ensure optimal hose routing.
- Use the closing cap to close the connection that is not in use. The Vitronic 55 W closing cap includes an inspection glass for function checks.

Dismantling the Unit Head
⚠️ CAUTION: The ultra-violet radiation of the UVC lamp can burn your eyes and skin. Never operate the UVC lamp outside the casing or in a damaged casing. Disconnect the unit from the power grid before starting any maintenance work or before replacing the UVC lamp.
⚠️ CAUTION: The quartz glass and UVC lamp could break and cause cuts. Act with caution when performing work on the UVC clarifier to avoid cuts. Avoid shocks, impacts, and abrupt movements to prevent the glass from breaking.
? For safety reasons, the UVC lamp can only be turned on when the UVC clarifier is properly installed in the unit.
How to proceed (Vitronic 11 W):
- Turn the unit head counter-clockwise up to the stop and carefully pull it out of the casing together with the O-ring.
How to proceed (Vitronic 18 W, 24 W, 36 W, 55 W):
- Push down the snap-fit hook, then turn the unit head counter-clockwise up to the stop and carefully pull the unit head out of the casing.
Diagram description: Illustrates the process of removing the unit head for Vitronic 11 W and Vitronic 18 W, 24 W, 36 W, 55 W models.
Fitting the Unit Head
How to proceed:
- Check the O-ring on the unit head for correct fit. Clean the O-ring; replace it if it is damaged.
- Carefully push the unit head into the casing up to the stop while applying slight pressure. While doing so, slightly turn the unit head to ensure that the tenons and the grooves of the bayonet closure mesh.
- Turn the unit head clockwise up to the stop.
Diagram description: Shows the steps for re-installing the unit head for Vitronic 11 W and Vitronic 18 W, 24 W, 36 W, 55 W models.
Cleaning the Quartz Glass / Replacing the UVC Lamp
Replace the UVC lamp after no more than 8000 operating hours. With constant operation, this corresponds approximately to one pond season. This ensures optimum filtering performance.
⚠️ CAUTION: The quartz glass and UVC lamp could break and cause cuts. Act with caution when performing work on the UVC clarifier to avoid cuts. Avoid shocks, impacts, and abrupt movements to prevent the glass from breaking.
Prerequisite:
- The unit head is removed. (Refer to 'Dismantling the unit head')
- Only use UVC lamps whose identification and power data correspond to the information on the type plate. (Refer to 'Technical data')
How to proceed:
- Loosen the self-tapping screw until its tip is sunk into the casing of the clamping screw.
- Carefully remove the quartz glass by pulling it forward with a slight turning movement.
- During installation, carefully push the quartz glass with the O-ring as far as the stop in the unit head. Ensure that the O-ring is located in the gap between the unit head and the quartz glass.
- Tighten the clamping screw up to the stop.
- Wipe the quartz glass with a damp cloth to remove dirt and fingerprints.
Diagram description: Illustrates the steps for removing and installing the quartz glass, including loosening a screw, removing the glass, and tightening a screw.
