2 Installation instructions
Install the continuous-flow heater as described in the illustrated
section. Observe the instructions in the text.
2.1 Installation
Unpacking/removing the cover (Fig. 1)
• Unpack the appliance and check for transport damage.
• Dispose of the packaging and, where applicable, the old appliance, in
an environmentally conscious manner.
Preparation for installation (Fig. 2)
Important: Only use the enclosed installation set.
• Shut off water supply. The electrical connection (connection cable)
must be disconnected from the power supply. Unscrew the fuse or
switch off the circuit breaker.
Wall mounting (Fig. 3)
• The continuous-flow heater must be fitted securely to the wall.
If required, secure the appliance using the lower adjusting screws.
• The distance from the wall is variable. This allows you to compensate
for any unevenness in the wall surface.
• The sleeve must fit tightly round the connection cable. If the sleeve is
damaged during installation, the holes must be sealed water-tight.
Water connection (Fig. 4)
• The continuous-flow heater must be vented. Open the warm water
tap fully and flush out the appliance thoroughly for 1 minute.
• The flow-rate limiter must be installed in the old water regulating
valve.
In accordance with EN60335-2-35, when the appliance is intended to
supply water for showering, the flow limiter must not be installed
(Fig. 6[A]).
Electrical connection (Fig. 5)
• The electrical supply terminal can be fitted at the top or bottom.
The sheath of the connection cable must extend for at least 40 mm
into the appliance.
Installation note
• The installation of non plug-in ready appliances must be undertaken
by the respective utility operator or by a qualified specialist company,
who can also assist you when you are requesting the approval of
the utility company for installation of the appliance.
Startup (Fig. 6/7)
The device is compliant to IEC 61000-3-12.
• At low water pipe pressure, check whether the 2 setting switches
on even when water is drawn from several cold-water taps simultane-
ously. If not, remove the flow limiter (refer to additional
information
Fig. 6, A ).
• The factory-installed flow rate limiters are designed for a outflow
temperature of approx. 42 °C (e. g. bathing and hand-washing
temperatures). If higher outflow temperatures are desired, install the
separately enclosed flow rate limiter.
• Instruct the user with regard to the operation of the continuous-flow
heater.
Additional information (Fig. 6, A/B)
• If the water pressure of the interior system is low, do not operate
the continuous-flow heater at full power, but remove the flow limiter
(
A, 3 ).
• Priority circuit for the combined operation of electric storage heaters
( B ).
For operation in a priority circuit, an electronic surge protection relay
of type DOLD IK 8715 6-40 A is necessary. Other surge protection
relays may lead to defective operation.
