Room/inlet air
Keep the inlet air free of contaminants. It must no t contain any
of the following substances:
• corrosive substances (ammonia, sulphur, halogen
products, chlorine, solvents)
• fatty or explosive substances
• aerosol concentrations
No other air inlet systems may be connected to the fan.
Refrigerant
▶ Please observe the applicable environmental regulations
when using and reusing refrigerant. Do not release it into the
environment! Use the refrigerant R134a. It is non flammable and does not damage the ozone layer.
▶ Before working on parts of the refrigerant circuit, remove
the refrigerant for safety reasons.
Please note that HFC-134a and PAG-ÖL are used during
service work. This is a chlorofluorocarbon and is rated with a
greenhouse potential of 1300 in the Kyoto Protocol.
Instructions to the customer
▶ Explain to the customer how the appliance works and how to
operate it.
▶ Advise the customer that he/she must not make any
modifications to the appliance or carry out any repairs on it.
Safety of electrical appliances 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:

3.8 Safety, control and protection devices
3.8.1 High Pressure Switch
If the operating pressure is outside of the recommended range,
the pressure switch switches off the appliance and displays a
fault ( chapter 11, page 28).
3.8.2 High limit safety cut-out
The high limit safety cut-out ensures that the water
temperature in the cylinder does not exceed the prescribed
limit. If the temperature limit is exceeded, the DHW heating
shuts down. The reset is performed manually by a certified
contractor.
3.8.3 Temperature sensor for air inlet
The temperature sensor measures the temperature of the inlet
air in the evaporator. If the measured value is outside the
operating temperature range, DHW heating automatically
switches from the "Combi" operating mode to "Electric booster
heater". If the appliance is in the "Heat pump" operating mode,
DHW heating is interrupted until the temperature returns to
within the permissible range.
3.9 Corrosion protection
The internal wall of the DHW cylinder is glass-lined (double
coating), making it neutral when in contact with water and
therefore suitable for potable water.
As an additional corrosion protection measure, the cylinder is
equipped with a magnesium anode. This must be inspected at
regular intervals and replaced if necessary.
The first inspection must take place 6
months after installation.
In regions with more corrosive water, safety measures (filter,
etc.) must be taken, and the magnesium anode must be
serviced more frequently.
