The product is intended for hot water generation.
Intended use includes the following:

• observance of the operating instructions included for the product and any other installation components
• compliance with all inspection and maintenance conditions listed in the instructions.
  This product can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the product in a safe way and understand the hazards involved.
  Children must not play with the product. Cleaning and user maintenance work must not be carried out by children unless they are supervised.
  Any other use that is not specified in these instructions, or use beyond that specified in this document, shall be considered improper use. Any direct commercial or industrial use is also deemed to be improper.
  Caution.
  Improper use of any kind is prohibited.

1.2 Danger caused by improper operation
Improper operation may present a danger to you and others, and cause material damage.
▶ Carefully read the enclosed instructions and all other applicable documents, particularly the “Safety” section and the warnings.
▶ Only carry out the activities for which instructions are provided in these operating instructions.

1.3 Risk of death caused by escaping refrigerant
The product contains R 290 refrigerant.
R 290 is an inflammable refrigerant.
When refrigerant escapes, there is a risk of explosion.

• If possible, open doors and windows fully and ensure adequate ventilation.
• Do not use naked flames (e.g. lighters, matches).
• Do not smoke.
• Do not use any electrical switches, mains plugs, doorbells, telephones or other communication systems in the building.
• Leave the building immediately and ensure that others do not enter the building.

1.4 Risk of death due to changes to the product or the product environment

• Never remove, bridge or block the safety devices.
• Do not tamper with any of the safety devices.
• Do not damage or remove any tamper-proof seals on components.
• Do not make any changes:
  – The product itself
  – The water and electricity supply lines
  – to the expansion relief valve
  – to the drain pipework
  – to constructional conditions that may affect the operational reliability of the  product

1.5 Risk of burns caused by touching hot surfaces
The outgoing lines and hydraulic connections are hot during operation.
▶ Do not touch any hydraulic connections.
▶ Do not touch any air inlets or outlets.

1.6 Risk of being scalded by hot drinking water
There is a risk of scalding at the hot water draw-off points if the hot water temperatures are greater than 60 °C. Young children and elderly persons are particularly at risk, even at lower temperatures.
▶ Select the temperature so that nobody is at risk.

1.7 Preventing the risk of injury from freezing as a result of touching refrigerant
The product is delivered with an operational filling of R 290 refrigerant.
This is a chlorine-free refrigerant which does not affect the Earth’s ozone layer. Escaping refrigerant may cause freezing if the exit point is touched.
▶ If refrigerant escapes, do not touch any components of the product.
▶ Do not inhale any steam or gases that escape from the refrigerant circuit as a result of leaks.
▶ Avoid skin or eye contact with the refrigerant.
▶ In the event of skin or eye contact with the refrigerant, seek medical advice.

1.8 Risk of injury and material damage due to maintenance and repairs carried out incorrectly or not carried out at all
▶ Never attempt to carry out maintenance work or repairs on your product yourself.
▶ Faults and damage should be immediately rectified by a competent person.
▶ Adhere to the maintenance intervals specified.

1.9 Risk of damage from corrosion caused by unsuitable room air
Sprays, solvents, chlorinated cleaning agents, paint, adhesives, ammonia compounds, dust or similar substances may lead to corrosion on the product.
▶ Ensure that the air supply is always free of fluorine, chlorine, sulphur, dust, etc.
▶ Ensure that no chemical substances are stored at the installation site.

1.10 Dangers of modifying product surroundings
Some types of installation and conversion work in your home can impair the way your product operates.
▶ Consult your installer before undertaking the work in question.

1.11 Frost damage due to insufficient room temperature
If the room temperature is set too low in individual rooms, it cannot be ruled out that sections of the heating installation might be damaged by frost.
The product may release cold air into the room. This means the room temperature can fall below 0 °C.
▶ If you are going to be away while the outside temperature is low, ensure that the heating installation remains in operation and that the rooms are sufficiently heated.
▶ You must observe the frost protection instructions.

1.12 Avoid environmental damage caused by escaping refrigerant
The product contains R 290 refrigerant. The refrigerant must not be allowed to escape into the atmosphere.
Before the product is disposed of, the refrigerant that is contained in it must be completely drained into a suitable vessel so that it can then be recycled or disposed of in accordance with regulations.
▶ Ensure that only officially certified competent persons with appropriate protective equipment carry out maintenance work on the refrigerant circuit or access it.
▶ Arrange for the refrigerant contained in the product to be recycled or disposed of by certified competent persons in accordance with regulations.

Appendix

A Troubleshooting

there has not been a power cut and that the product is correctly connected to the power supply. When the power supply is reestablished, the product automatically starts up. If a fault is still present, contact your competent person.
The set target temperature of the water is reached.| Check the domestic hot water temperature.
The product is switched off.| Check whether the
product is switched on and the green LED is lit up.
The product is in holiday mode.| Switch off holiday mode.
The air inlet temperature is below -7 °C or above +35 °C.| Ensure that the domestic hot water cylinder is heated using the backup energy sources (immersion heater). If the air inlet temperature is
once again between -7 °C or and +35 °C, the heat pump restarts.
Time programming conflicts with the high-tariff load relief.| Check the time programming.
A programmed operating time is pre- venting operation (ECO symbol is lit up).| Check the set operating times.
There is a hot water shortage.| The domestic hot water volume, which was used within a short space of time, is larger than the volumetric capacity of the domestic hot water cylinder.| Wait until the domestic hot water cylinder is sup-plied with sufficient hot water again.
The programmed operating time for the heat pump is too short (at least 12 hours in a 24 hour period).| Set the operating time so that the domestic hot water cylinder is charged for at least 12 hours in a 24 hour period.
The setting for the set target temperat- ure is too low| Increase the set target temperature.
Time programming conflicts with the high-tariff load relief.| Check the time programming.
