Maintenance and wintering
Nature
2
Fusion does not need any special maintenance. However, if the pool is
used all year round, it is strongly recommended that the appliance be purged
and cleaned at least once every year in order to make sure there are no deposits
inside the diffuser and chlorinator.
➤
Follow the wintering procedure described below to purge and clean the
Nature
2
Fusion system.
If the pool is wintered (fi ltering and treatment stopped, reduced water level and
piping purged...) it is essential to purge and clean the Nature
2
Fusion system in
order to avoid risks of freezing.
Wintering procedure:
1.
Once the piping has been purged and the fi ltering stopped, remove and
dispose of the Nature
2
Fusion cartridge after having unscrewed the black ring
holding it in place (various waste, not an environmental hazard).
For Nature
2
Fusion to operate correctly it is essential to carry out a start-up
treatment when a Nature
2
Fusion cartridge is installed.
Start-up procedure:
1.
To activate the Nature
2
Fusion cartridge optimally, proceed with a light shock-
chlorination after the cartridge has been fi tted. Only add shock chlorine in
the skimmer(s) to obtain a free chlorine level between 3 and 4 ppm with 24hr
continuous fi ltering for 3 days. Use the quantities indicated on the packaging to
obtain the required concentration.
2.
Adjust the chlorine dosage to the maximum on the Nature
2
Fusion system
using the adjustment ring on the diffuser (position 5).
3.
Operate the Nature
2
Fusion system on this maximum setting for 3 days in
order to maintain the free chlorine level between 1 and 2 ppm during this time
(fi ltering operating in normal «automatic» mode).
4.
Following this activation period let the chlorine level drop to between 0.5
and 1.0 ppm (standard treatment). Adjust the level of free chlorine using the 6
setting adjustment ring (it would be useful to analyse the water every week).
Remark:
This start-up treatment must be carried out each time the Nature
2
cartridge is replaced (preferably when starting up after wintering). It is
designed to obtain the highest effi ciency from the Nature
2
treatment as quickly
as possible.

2.
Remove the «adjustment ring + black ring» from the chlorinator after
having unscrewed the black ring holding it in place. Next unscrew the purge
screw located on the side at the base of the appliance in order to empty the
Nature
2
Fusion diffuser reservoir. Be careful not to mislay the torque joint on the
purge screw.
3.
Remove and clean the black cylinder containing any eventual remaining
tablets using clear water. Rinse the diffuser in clear water (purge screw still
removed). Then replace the black cylinder in its housing.
4.
Make sure there is no remaining water in the appliance before replacing the
purge screw (manual tightening!).
5.
Clean the joints using clean water if necessary and then close the
Nature
2
Fusion system. Replace the chlorinator «adjustment ring + black ring»
then use the supplied wintering cap to cover the Nature
2
Fusion cartridge
housing using the black tightening ring.
