ter quality from a microbiological point of view.
The softener is a technical piece of equipment for commercial use
and is not intended for private use.

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.

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.
