Installation
- Make sure that the area is flat and strong enough to handle all weight including spa, water, and people.
- The water supply must be filled exclusively by network distribution water. If your spa is equipped with automatic filling, a water supply via a DN15 connection pipe is required. For draining the spa and backwashing, evacuation is via a DN50 pipe. We recommend to use our water treatment system UBO PERFORMANCE or UBO PERFORMANCE PRO, which not only filters out all particles to offer you clear water but also sterilize the whole spa with UV and Ozone technology Ultra-Bio-Ozone®.
- Power supply: depends on the selected water treatment system.
