to provide you with information on how to operate the device and
how it functions. The softener may only be operated as described
in these operating instructions.
2 Product description
The softener consists of a mobile plastic container and a removable
cover. The regeneration salt is placed into the container.
Two cartridges are integrated into the container. The cartridges are
filled with exchange resin and are connected together.
Water softening is based on the principle of ion exchange. The
exchange resin in the cartridges binds with the hardening ions from
the raw water flowing through the device and releases other non-
hardening ions into the water. The softened water has a total hard-
ness of 0 °dH.
The capacity of the exchange resin is limited. It depends on the total
hardness of the raw water. The exchange resin must be regenerated
when it has been used up. The control head on the cartridges con-
trols regeneration depending on the water hardness set. When a
cartridge is depleted the unit switches to the second cartridge, and
the depleted cartridge is regenerated, ensuring that softened water is
continuously available.
3 Installation and connection
3.1 Installation site requirements
The room must be frost-free.
A water drain must be located near the softener. The water drain
must not be higher than the safety overflow on the rear of the sof-
tener.
Ideally the room has a floor drain.
The installation location must be horizontal and even. Slight incli-
nations such as are usual in kitchens do not impair functioning,
however the softener should be secured against rolling.
The softener should preferably be installed on the floor. If the
softener is placed on a base, the castors should be removed.
There should be sufficient space above to ensure that the cover
can be removed easily during the refilling of regeneration salt.
See connection diagram for connections for water inlet and water
drain (page 10).
3.2 Preparing control head
Remove the cover of the container.
Take the hoses and assembly kit out of the container.
Equip the adapters (1) with the O-rings (2) and grease with sili-
cone grease.
Plug the adapters (1) onto the "in" and "out" connections.
Secure with handle (4) and pin (3).
3.3 Connecting
Caution
Connection of the softener to the drinking water network
and to the waste water must be performed according to
the country-specific, local conditions by an approved
water fitter.
National installation and operating regulations as well as
details on the connection diagram on page 10 must be
observed.

from Winterhalter for this purpose.
The kit contains a backflow preventer type HD in accordance with
DIN EN 1717.
Installation of the water safety device is shown in the drawing.
Should national guidelines not require a check valve or anti-vacuum
device, the water supply hose (2) is connected directly at the control
head (3).
3.5 Installing dirt trap
After the water stop cock (1),
install a dirt trap (2) with a
mesh width of 150 µm.
INFO The dirt trap en-
closed with Win-
terhalter warewash-
ers is suitable for this
purpose.
Connect supply hose (3).
3.6 Connecting the waste water hose and overflow
hose
Attach waste water hose to the
hose nipple and secure with a
hose clamp.
Guide the waste water hose to
the on-site water drain.
Attach a hose to the safety
overflow on the rear of the sof-
tener and guide this to the on-
site water drain.
Attach both hoses to the water
drain at a distance of 20 mm
(see drawing).
4 Commissioning
After the machine has been correctly connected to the water supply
and waste water drain, contact your Winterhalter branch or your
dealer in order to request them to perform commissioning. You can
use this opportunity for you and your operating personnel to learn
how to operate the softener.
5 Operation
The softener works automatically following commissioning. Only the
regeneration salt must be refilled from time to time.
Caution
Possibility of damage due to incorrect salt.
Only use undenaturated evaporated salt (approx. 15 mm
granularity or in tablet form) marked as regeneration salt
for softeners. Do not use any other types of salt e.g.
table salt, rock salt or de-icing salt. These may contain
components that are not soluble in water.
Refill the regeneration salt as
soon as the water in the contain-
er is above the level of the salt.
6 Maintenance
Caution
Possibility of damage due to chemicals.
Do not clean the inside of the container with cleaning
agents or other chemicals.
Only ever clean the container with water.
Clean the outside of the softener using conventional plastic kitch-
en hygiene products.

mmol/l 1mmol/l= 5.6 7.02 10.00 1.0
3 Adjusting and installing the brine valve
Determine the total hardness of the
raw water:
Total hardness ≤40 °dH:
Use standard setting (5 mm).
Total hardness > 40 °dH:
Change distance (a) to 17 mm.
INFO The salt consumption per
regeneration increases
from 0.3 kg to 0.5 kg.
Ensure that the valve base (1) is
sitting in the recess of the container
base and that it is possible to move
the float cup vertically approx. 6 mm.
Fasten riser pipe of the brine valve
onto the control head using the en-
closed screw connections (2).
