General safety instructions
HGeneral safety instructions
Failure to observe the safety instructions can result in serious personal
injury with potentially fatal consequences as well as damage to property
and the environment.
▶ Installation and commissioning as well as maintenance and repairs
must only be carried out by an approved and qualified heating
contractor.
▶ Read these instructions carefully.
▶ Only perform work described for the user group concerned
(users, contractors). Other activities can lead to malfunctions,
material damage and personal injury.
▶ Carry out cleaning and maintenance at least once a year. Also check
when you do so that the entire system is in proper working order.
▶ Immediately remedy any defects identified.
HOriginal spare parts
The manufacturer assumes no liability for damage caused by spare parts
not supplied by the manufacturer.
▶ Use only original spare parts and accessories from the manufacturer.

Explanation of symbols and safety instructions
HRisk of scalding
Risk of scalding from DHW temperatures over 60 °C.
▶ Do not draw off DHW unmixed.
HSafety of electrical devices for domestic use and similar purposes
The following requirements apply in accordance with EN 60335-1 in order
to prevent hazards from occurring when using electrical appliances:
"This appliance can be used by children of 8 years and older, as well as
by people with reduced physical, sensory or mental capabilities or
lacking in experience and knowledge, if they are supervised and have
been given instruction in the safe use of the appliance and understand
the resulting dangers. Children shall not play with the appliance.
Cleaning and user maintenance must not be performed by children
without supervision."
"If the power cable is damaged, it must be replaced by the manufacturer,
its customer service department or a similarly qualified person, so that
risks are avoided."
HRisk of fatal injury from electric current
▶ Observe the relevant requirements when working on electrical
installations.
▶ Installation and commissioning as well as service and maintenance
must only be carried out by an approved and qualified contractor.
▶ Before unpacking the appliance, touch a radiator or an earthed metal
water line to discharge any electrostatic charge in your body.
▶ Ensure that a country-specific emergency isolation switch
(emergency-off button) is present.
In the case of systems with three-phase consumers, incorporate the
emergency isolation switch into the safety chain.
▶ Ensure that a standards-compliant disconnection device in accordance
with EN 60335-1 is available for all-pole disconnection from the power
grid. If there is no circuit breaker present, you must install one.
▶ Before opening the controller, disconnect all poles of the heating
system via the circuit breaker. Secure against unintentional
reconnection.
▶ Size cables according to how they are to be laid and environmental
conditions. The cable cross-section for power outputs
(e.g. pumps, mixers) must be at least 1.0 mm
HHeating system damage due to frost
When the heating system is not in operation (e.g. control unit switched
off, fault shutdown), there is a risk of it freezing when there is frost.
▶ When decommissioning or switching off for extended periods, drain
the heating and drinking water pipes at the lowest point in order to
protect the heating system from freezing and drain at further
drainage points (e.g. upstream of the non-return valves).
HHandover to the user
When handing over, instruct the user how to operate the heating system
and inform the user about its operating conditions.
▶ Explain how to operate the heating system and draw the user's
attention to any safety relevant action.
▶ In particular, point out the following:
– Alterations and repairs must only be carried out by an approved
contractor.
– Safe and environmentally compatible operation requires
inspection at least once a year and responsive cleaning and
maintenance.
– The heat generator may only be operated with the casing fitted
and closed.
▶ Point out the possible consequences (personal injury, including
danger to life or material damage) of non-existent or improper
inspection, cleaning and maintenance.
▶ Point out the dangers of carbon monoxide (CO) and recommend the
use of CO detectors.
▶ Leave the installation instructions and the operating instructions with
the user for safekeeping.
