IMPORTANT
After the sanitisation procedure, use a measuring kit to check the concentration of
free chlorine in the permeate water. The concentration permitted for drinking water
may vary based on local standards. For some technical applications, the concen-
tration of chlorine permitted is under that permitted for drinking water.
See the technical data sheet and the safety data sheet, which can be requested
from the manufacturer.
If necessary, the O-rings can be replaced on the head.
1. Using the key (6), remove the clips of the O-ring (5) seat, rotating the clips counter-
clockwise
2. Remove the O-rings and replace with original spare parts, apply food-grade silicone
grease.
3. Re-assemble the clips on the seats (5) by applying a light pressure.
Procedure to replace the membranes
1. Vessel
2. Locking slider
3. Osmotic membrane 3012
4. Sealing plug
5. Vessel key
6. Closing plug
For filter replacement, proceed as follows
Turn off the electrical power supply to the system;
for the SLIM versions, close the shut-off valve of the
water supply circuit, and dismantle the vessel unit
of the system.
Always replace all the system membranes.
1. Remove the machine casing.
In the SLIM versions, the vessel unit must be
dismantled.
2. Dismantle the orange closing plugs, using the
locking slider.
3. Dismantle the vessel sealing plugs, rotating with the vessel key or, if not available, using
an adequate pin inserted in the plug eyelets.

5. Position the new membranes
6. Assemble the vessel sealing plugs (if necessary, apply food-grade silicone grease),
assemble the closing plugs until the locking slider triggers
