Installation
The Nature
2
Fusion system must be installed
downstream from the fi ltering
system
and
any eventual heating system
(heat pump, heat exchanger,
electric warmer...).
• For pools fi tted with a heating system where the Nature
2
Fusion system is
to be installed downstream on the same bypass, leave a minimum distance
of at least 1 metre between the two appliances. Install a check valve
between the two appliances if the distance is less.
Nature
2
Fusion must be placed fl at on the ground or on a horizontal and
stable support.
• If the Nature
2
Fusion system is installed in a technical room, it should be
ventilated and/or well aired.
It is recommended to install the Nature
2
Fusion system on a bypass (or
in «parallel»). The maximum permitted fl ow in the diffuser is 25 m
3
/hr;
installing the system on a bypass is COMPULSORY for fl ows exceeding this
value (on the contrary an in-line installation is possible below the maximum
permitted fl ow).
The minimum fl ow for correct operation of the appliance is of 6.5 m
3
/hr.
• Special case for above-ground pools:
If the Nature
2
Fusion system is installed on an above ground pool fi tted
with fl exible ringed piping, use the supplied above ground connection kit.
It has two adapters for 32 or 38 mm pipes that are to be glued into the
DN50/63 mm diffuser joints.
For all gluing (rigid pipes for in ground pools and adapters for above ground
pools) use «blue» PVC adhesive (sand the surfaces manually before applying
adhesive to the parts to be assembled).

IMPORTANT!!
Nature
2
Fusion must be installed in the right direction: the
water fi rst passes through the Nature
2
Fusion cartridge and then through
the chlorinator.
Make sure you follow the water fl ow direction as indicated on the body of
the diffuser:
➤
INLET = water intake
(Nature
2
Fusion cartridge side)
➤
OUTLET = water outlet
(chlorinator side).

Fitting the Nature
2
Fusion cartridge
The Nature
2
Fusion system is delivered without the mineral treatment
cartridge. The cartridge must be purchased separately (cartridge
model selected depending on pool volume; refer to chapter 1 «Technical
Specifi cations» table).
The Nature
2
Fusion cartridge must be replaced at the beginning of each
season or every 6 months in pools that are used all year round (
maximum
use 6 months
beginning on the cartridge installation date).
Fitting the Nature
2
Fusion cartridge:
1. Stop the fi ltering pump.
2. Close all the safety valves that may be located between the fi lter and
the pool.
3. Unscrew the black ring that maintains the cap (or the cartridge) in place.
> On a new appliance: remove the wintering cap.
> To replace a used cartridge: remove the existing cartridge.
4. Insert the new Nature
2
Fusion cartridge
and replace the black ring (only
manual tightening!).
5. Open the previously closed safety valves.
6. Restart
the fi ltering pump.
7. Follow the activation procedure
(see chapter 7 «Getting started»).
