INSTALLATION

7. Safety

Only a qualified contractor should carry out installation,
commissioning, maintenance and repair of the appliance.
7.1 General safety instructions
We guarantee trouble-free function and operational relia-
bility only if original accessories and spare parts intended
for the appliance are used.
Material losses
!
Observe the maximum inlet temperature. Higher
temperatures may damage the appliance. You can
restrict the maximum inlet temperature by installing
a central thermostatic valve.
WARNING Electrocution
This appliance contains capacitors which are dis-
charged when disconnected from the power supply.
The capacitor discharge voltage may briefly reach
> 60 V DC.
7.2 Shower operation
CAUTION Burns
» If supplying a shower, set the internal temper-
ature limit to "Tred"; see chapter "Installation
alternatives / Temperature limit".
CAUTION Burns
If the water supplied to the appliance is preheated,
please note the following:
The internally adjustable temperature limit may be
exceeded.
» Limit the temperature with an upstream central
thermostatic valve.
7.3 Instructions, standards and regulations
Note
Observe all applicable national and regional regula-
tions and instructions.
◦ The IP 25 (hoseproof) rating can only be ensured
with a correctly fitted cable grommet.
◦ The specific electrical resistivity of the water must
not fall below that stated on the type plate. In a linked
water network, observe the lowest electrical water
resistivity (see chapter "Specification / Application
areas / Conversion table"). Your water supply utility
will advise you of the specific electrical water resis-
tivity or conductivity.

8.2 Accessories
Tap
ADEo 70 WD bath pressure tap
Installation accessories
Pipe assembly, undersink installation UT 104, connec-
tions: Finished walls, G 3/8, top. Water connections with
12 mm compression fitting.
Universal mounting frame
Mounting frame with electrical connections.
Pipe assembly for undersink appliances
This assembly for undersink installation is required if you
need to have the water connections (G ⅜ A) above the
appliance.
Pipe assembly for offset installation
This pipe assembly with pipe bends is required if you need
to have the appliance vertically offset against the water
connection by approx. 90 mm downwards.
Pipe assembly for replacing a gas water heater
This pipe assembly is required if the installation has exist-
ing gas water heater connections (cold water connection
on the left and DHW connection on the right).
Load shedding relay (LR 1-A)
The load shedding relay for installation in the distribution
board provides priority control for the instantaneous water
heater when other appliances, such as electric storage
heaters, are being operated simultaneously.
Central thermostatic valve
Use the thermostatic valve for central premixing when
operating an instantaneous water heater with preheated
water, for example. For use in shower operation, the valve
must be set to a maximum of 55 °C.

9. Preparation
