7. Safety
Only a qualified contractor should carry out installation, commis-
sioning, maintenance and repair of the appliance.
7.1 General safety instructions
We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
Flow pressure
If the flow rate is insufficient to switch on the appliance even when
the tap is open, remove the flow limiter and replace it with the
plastic profile washer supplied.
If required, the pressure in the water installation can also be
raised.
Note
For the thermostatic valve to function correctly, the flow
limiter for this valve must not be replaced with the plastic
profile washer.
!
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 ther-
mostatic valve.
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.
7.2 Shower operation
CAUTION Burns
f f If supplying a shower, set the internal temperature
limit to "Tred"; see chapter "Installation alterna-
tives / Temperature limit".
CAUTION Burns
If the water supplied to the appliance is preheated,
please note the following:
The internally adjustable temperature limit may be ex-
ceeded.
f f
Limit the temperature with an upstream central
thermostatic valve (ZTA 3/4).
7.3 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, observe the lowest electrical water resistivity (see
chapter "Specification / Application areas / Conversion
table"). Your water supply utility will advise you of the specif-
ic electrical water resistivity or conductivity.
