Installation - Erie water treatment H2Optimo Twister Instructions D'installation & Emploi

Picture 1&11
To facilitate the installation, you may want to remove the salt
lid and main cover from the water softener.
1. Remove the salt lid.
2. Unscrew the screw rivets at the front of the main cover.
3. Carefully lift the main cover from the water softener.
CASTER WHEELS (optional on micro & mini)
In case the water softener is delivered with the optional
caster wheel set, it needs to be mounted on the cabinet upon
installation of the water softener.
Picture 2
1. Position the reinforcement plate on the bottom of the
water softeners cabinet, making sure the 4 holes in the
reinforcement plate align properly with the 4 threaded
sockets in the cabinet.
2. Screw the 4 caster wheels into the threaded sockets;
make sure to install the washers. Tighten firmly. Make
sure the 2 caster wheels with brake are easily accessible.
INLET & OUTLET

Check the water pressure at the place of installation of
the water softener; it should never exceed 5,0 bar in case of
hot water application (max. 65 °C) or 8,3 bar in case of cold
water application (max. 48 °C).

In case of high concentration of impurities in the inlet
water, we recommend the installation of a sediment filter,
ahead of the water softener.

We strongly recommend the use of flexible hoses to
connect the water softener to the water distribution system;
use hoses with a large diameter in order to limit the pressure
loss.

The inlet/outlet adaptors are equipped with an
integrated non-return valve, to prevent any kind of backflow
into the water softener or mains water supply; make sure to
install them in the correct flow direction!

If the water softener is not equipped with the factory
bypass (optional), we strongly recommend to install a 3-
valve bypass system (not included with this product!) to
isolate the water softener from the water distribution
system in case of repairs. It allows to turn off the water to
the water softener, while maintaining (untreated) water
supply to the user.
WITH FACTORY BYPASS (optional)
Picture 3
 = mains water supply (untreated water)
 = inlet of water softener (untreated water)
 = outlet of water softener (treated water)
 = application (treated water)
1. Screw the factory bypass onto the elbow connections of
the water softener (&); make sure to install the
gasket seals. Tighten the nuts firmly by hand.
2. Screw the connection kit with nuts onto the factory
bypass (&); make sure to install the gasket seals.
Tighten the nuts firmly by hand.

INSTALLATION

3. Connect the mains water supply to the adaptor on the
inlet port of the factory bypass ().
4. Connect the house/application to the adaptor on the
outlet port of the factory bypass ().
WITH 3-VALVE BYPASS SYSTEM (not included)
Picture 4
 = inlet of water softener (untreated water)
 = outlet of water softener (treated water)
1. Install the 3-valve bypass system.
2. Screw the connection kit with nuts onto the elbow
connections of the water softener (&); make sure to
install the gasket seals. Tighten the nuts firmly by hand.
3. Connect the 3-valve bypass system to the adaptors on the
in () and out () elbow connections.
4. Connect the mains water supply to the inlet of the 3-valve
bypass system.
5. Connect the house/application to the outlet of the 3-valve
bypass system.

We recommend the use of a stand pipe with air trap.

To prevent backflow from the sewerage system into the
water softener, always install and use the included air gap
with double hose barb, to connect the drain hoses to the
sewerage system.

Always use separate drain hoses for the control valve
(evacuation of rinse water) and the softener cabinet's
overflow.

Lay-out the drain hoses in such a way that pressure loss
is minimized; avoid kinks and unnecessary elevations.

Make sure that the sewerage system is suitable for the
rinse water flow rate of the water softener.
Picture 5
1. Install the air gap to the sewerage system; it fits over a
32 mm pipe or inside a 40 mm pipe adaptor. Ensure a
permanent and watertight connection.
2. Connect a 13 mm hose to the drain elbow connection of
the control valve (); secure it by means of a clamp.
3. Run the drain hose to the air gap and connect it to one of
the hose barbs; secure it by means of a clamp. This drain
line operates under pressure, so it may be installed higher
than the water softener.
4. Connect a 13 mm hose to the cabinet overflow elbow,
located at the back side of the water softener; secure it
by means of a clamp.
5. Run the drain hose to the air gap and connect it to the
other hose barb. This drain line does NOT operate under
pressure, so it may NOT be installed higher than the water
softener.
