Fusion can be used optimally and without risks in all pool structures
with all types of surfaces (
if the pool water = public utility network
):
• Liners and reinforced PVC (presence of treated felt beneath)
• Painted concrete
• Tiling
• Polyester shells or treatments
The manufacturer will not be liable if unsuitable well water is used to fi ll the
pool.
Water balance:
In order to have Nature
2
Fusion operate in optimal conditions and to avoid
problems in the pool it is essential to regularly measure water balance levels.

Preparing to install
Before starting the Nature
2
Fusion system remove all eventual debris and
algae from the pool water and clean the fi lter.
Important:
Only install the new Nature
2
Fusion cartridge once the pool
water is clean and balanced. Please consult the values in the water bal-
ance table in chapter 2. In the event of any problems ask your Nature
2
reseller for advice.
