equipment,฀must฀only฀be฀carried฀out฀by฀a฀qualiied฀contractor฀in฀accordance฀with฀these฀instructions.

•฀ Perfect฀function฀and฀safe฀operation฀can฀only฀be฀assured฀when฀using฀original฀accessories฀and฀spare฀parts฀

intended for this equipment.

•฀ Observe฀all฀locally฀applicable฀instructions฀and฀regulations฀regarding฀water฀and฀electrical฀connections,฀such฀

as DIN VDE 0100, DIN 1988, DIN 4109, DIN 44851.

•฀ Observe฀all฀regulations฀of฀your฀local฀water฀and฀electricity฀supply฀companies.
•฀ The฀equipment฀type฀plate.

(

A

•฀ See฀"5.1฀Speciication".

The specific electrical resistant of the water used must not fall below that stated on the type plate 
of the equipment. In a linked water network, observe the lowest electrical water resistance (see "5.2 
Application areas"). Your water supply company will advise you of the specific electrical water resistance 
or conductivity.

•฀ Install฀the฀device฀only฀in฀an฀enclosed฀room฀free฀from฀the฀risk฀of฀frost.฀Store฀the฀dismantled฀device฀in฀a฀

room free from the risk of frost, as water residues remain inside the device.

Water installation

:

–  Material of the cold water line:

  Steel, copper or plastic pipework.

–  Material of the DHW line:

  Copper or plastic pipework*.

*  The instantaneous water heater can reach operating temperatures up to 85 °C. In case of faults, loads 

up to 95 °C / 1.2 MPa can occur temporarily in the installation. Any plastic pipework used must be suitable 
for these conditions.

•฀ A฀safety฀valve฀is฀not฀required.
•฀ Never฀operate฀with฀pre-heated฀water.
•฀ Never฀use฀taps/valves฀for฀open฀vented฀equipment.
•฀ For฀thermostatic฀valves,฀see฀"1.6฀Recommended฀adjustment฀of฀taps/valves".
•฀

Electrical installation:

•฀ Use฀only฀permanently฀wired฀power฀cables.
•฀ The฀equipment฀must฀be฀able฀to฀be฀separated฀from฀the฀mains฀power฀supply,฀for฀example฀by฀fuses฀that฀

disconnect all poles with at least 3 mm contact separation.
