Overpressure and fluctuation protection:
Water pressure must never exceed the unit‘s maximum of 5.0 bar UK, 8.0 bar EU.
If the network water-pressure is higher than 4.0 bar UK, 6.0 bar EU (or you are unsure about pressure),
a pressure reducer (pressure reducing valve) must be installed upstream of the unit.
During pressure fluctuations or surges, the sum of the pressure surge and the standing pressure is not to
exceed the nominal pressure.
Electrical interference:
The emission of interference (EMI = voltage peaks, high-frequency electromagnetic fields, interference
voltages, voltage fluctuations…) by the surrounding electrical systems may not exceed the maximum
values specified in EN 61000-6-3.
Data analysis of the hard water in your area:
Continuous operation of the water softener with water containing chlorine or chlorine dioxide is possib-
le if the concentration of free chlorine/chlorine dioxide does not exceed 0.5 mg/l. The type of pre-treat-
ment must be determined at each location.
Principle of intelligent regeneration:
The unit should be sized according your current water consumption. If water consumption is reduced,
e.g. during holidays, a tap must be fully opened for at least 5 minutes before water can be used
again.
Inlet- and outlet connections:
When installing the unit, select a location where the unit can easily be connected to the water supply
network. A connection to the waste water system (at least DN 50), a floor drain and a separate mains
socket (see chapter 7 Technical data) must be nearby.
Overflow hose connection:
A suitable overflow hose connection is required to remove the waste water.
Preconditions for the hydraulic installation:
Observe the hydraulic and electrical requirements for installation for first commission (see chapter 5
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 after-sales
service department and quote the model type and the production number (see chapter 7 Technical data
or the rating plate on unit).
NOTE!
f
Only your local after-sales service staff may perform any works under the guarantee.
f
Any work performed by a third party must be directly commissioned by your after-sales service.
