INSTALLATION
Page 5
Picture 1&10
To facilitate the installation, you may want to remove the
salt lid and main cover from the water softener.
INLET & OUTLET

Check the water pressure at the place of installation of
the water softener; it should never exceed 8,3 bar.

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.

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.

1. Screw the factory bypass onto the elbow connections of
the water softener (

gasket seals. Tighten the nuts firmly by hand.
2. Screw the connection kit with nuts onto the factory
bypass (

Tighten the nuts firmly by hand.
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 (

DRAIN

We recommend the use of a stand pipe with air trap.

To prevent backflow from the sewerage system into the
water softener, always make sure to have an air gap
between the end of the drain hose and the sewerage
system itself; as a rule of thumb, the air gap should be
minimum 2x the diameter of the drain hose.

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 4
1. Connect a 13 mm hose to the drain solenoid of the
control valve (

); secure it by means of a clamp.
2. Run the drain hose to the sewerage system and connect
it to the stand pipe assuring sufficient air gap. This drain
line operates under pressure, so it may be installed
higher than the water softener.
3. 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.
4. Run the drain hose to the sewerage system and connect
it to the stand pipe assuring sufficient air gap. This drain
line does NOT operate under pressure, so it may NOT be
installed higher than the water softener.
ELECTRICAL
Picture 5
1. Plug the transformers output lead into the socket on the
water softeners power cord; secure it by means of the
TwistLock clamp.
2. Plug the transformer into an electrical outlet.
