EN
A connection to the waste water system (at least
DN50), a oor drain and a separate mains socket
(see technical data) must be nearby.
Overow hose connection:
A suitable overow hose connection is
recommended to remove any overow waste water.
Exclusion of warranty:
Non-compliance with the installation conditions and
the operator responsibilities voids the warranty.
Guarantee:
In the event of a malfunction of the unit during the
guarantee period, please contact your aftersales
service department and quote the model type and
the serial number (see technical data or the rating
plate on unit).
Note: Only your local aftersales service staff may
perform any works under the guarantee.
Any work performed by a third party must be
directly commissioned by your aftersales service.
The warranty symbol will show in the
softener display when your warranty
period has ended.
3.2 Initial commissioning
1. Handing over the unit to the operator:
If there is a delay between the installation/startup
of the unit and transfer to the operator, a manual
regeneration must be performed. The operator
must be told how the unit works as well as how to
operate and inspect it. Ensure that the operator
receives the installation and operating manual.
2. Inlet and outlet connections:
Please check connections and pipeline junctions
for leaks.
3.3 Installation and operation
considerations
Important - Never install the water softener where
it, or its connections (including the drain overow
lines), will be subject to temperatures under 0°C or
above 40°C. If you are planning to install the water
softener above ground level e.g. In the loft, the
following instructions should be strictly adhered to:
1. Loft installation
The water softener should be installed within a
container of not less than 100 litre capacity, to
which there should be connected an overow pipe
of not less than 20mm diameter. The overow
should be connected at the bottom of the container
and not less than 15mm below the height of any
electrical components mounted on the water
softener. It is recommended that an anti-vacuum
valve be tted to the inlet pipework supplying the
water softener.
Plumbing systems
2. Backow prevention device
When tted to the supply feeding a single dwelling,
a check valve complying with national regulations
must be tted on the cold water feed prior to the
installation. All other types of installation require the
tting of a double check valve.
3. Drinking water
Your water softener installation must include at
least one drinking water tap that is not fed by the
water softener. In case of low sodium diet follow the
local department of health‘s advice concerning the
use of softened water for drinking.
Note: Water that is used for mixing powdered milk
for babies must only be taken from an unsoftened
mains tap as some powdered milks and softened
water both contain small traces of additional
sodium for which young babies have a limited
tolerance.
Operating pressure
If pressure more than:
4 bar install pressure
reducing valve.
(UK models only).
Do not operate with a
pressure less than: 1.7 bar
