are used.
Material losses
!
Observe the maximum inlet temperature. Higher tem-
peratures may damage the appliance. You can limit
the maximum inlet temperature by installing a central
thermostatic valve (see chapter "Appliance description /
Accessories").
WARNING Electrocution
This appliance contains capacitors which are discharged
when disconnected from the power supply. The capacitor
discharge voltage may briefly reach > 60 V DC.

Shower operation
CAUTION Burns
f When supplying a shower, set the internal an-
f
ti-scalding protection to 55 °C or less; see chapter
"Commissioning / Preparations".
CAUTION Burns
If the water supplied to the appliance is preheated,
please note the following points:
- The internally adjustable anti-scalding protection
and the temperature limit that is adjustable by the
user may be exceeded.
- The dynamic anti-scalding protection between the
appliance and the wireless remote control may not
be effective.
f In both cases, limit the temperature with an up-
f
stream central thermostatic valve (ZTA 3/4).

Instructions, standards and regulations
Note
Observe all applicable national and regional regulations
and instructions.
- The IP 25 (hoseproof) rating can only be ensured with a cor-
rectly fitted cable grommet.
- The specific electrical resistivity of the water must not fall
below that stated on the type plate. In a linked water net-
work, factor in the lowest electrical resistivity of the water.
Your water supply utility will advise you of the specific elec-
