Any other use or use beyond the intended use is considered improper use. The operator alone bears responsibility for any resulting damage.

Intended use also includes compliance with the maintenance and service conditions. Spare parts must at least satisfy the technical requirements defined by the manufacturer. This is the case, for example, with original spare parts.

1.2.3 Installation room

WARNING

The plastic wall of the storage tank on the indoor unit can melt under the effects of external heat (>80°C) and, in the extreme case, can catch fire.

▪ Only install the indoor unit at a

minimum clearance of 1m from other heat sources (>80°C) (e.g. electrical heater, oil heater, chimney) and combustible materials.

CAUTION

▪ Only install the indoor unit if sufficient

load-carrying capacity of the ground of 1050kg/m2 plus safety margin is ensured. The ground must be flat, horizontal and level.

▪ Outdoor set up is not permissible.

▪ Set-up in an explosion-risk

environment is not permissible.

▪ The electronic control system must

not be exposed to weather effects such as rain and snow under any circumstances.

▪ The storage tank may not be

exposed to continuous direct sunlight, as the UV radiation and the effects of the weather will damage the plastic.

▪ The indoor unit must be installed

protected from frost.

▪ Make sure that the supply company

does not provide corrosive domestic water. Suitable water treatment may be required.

▪ Always ensure the minimum distances from walls and other

objects ("3.1Dimensions and connection dimensions"[411]).

▪ Observe the special installation requirements of the R32

refrigerant (see "3.3.1Selecting the installation site"[412]).

008.1451099_00 – 07/2020

Installation and operating manual

1 General safety precautions

CAUTION

▪ If a DrainBack solar heating

system is connected: Install the indoor unit far enough under the solar panels to allow complete emptying of the solar heating system. (Follow the instructions in the DrainBack solar heating system manual.) An insufficient height difference may lead to destruction of the DrainBack solar heating system.

▪ The indoor unit must not be operated

in rooms with ambient temperatures of more than 40°C.

1.2.4 Electrical installation

▪ Electrical installations may only be carried out by electrical

technicians and in compliance with valid electrical guidelines as well as the specifications of the responsible energy supply company.

▪ Compare the mains voltage indicated on the nameplate with the

supply voltage before connecting to the mains.

▪ Before beginning work on live parts, disconnect them from the

power supply (switch off main switch, remove fuse) and secure against unintentional restart.

▪ Device covers and service panels must be replaced as soon as

the work is completed.

1.2.5 Requirements for heating and storage water

Damage due to deposits and corrosion: observe the relevant technical rules to avoid corrosion products and deposits.

Minimum requirements regarding the quality of filling and top-up water:

▪ Water hardness (calcium and magnesium, calculated as calcium

carbonate): ≤3mmol/l

▪ Conductivity: ≤1500 (ideal ≤100)μS/cm

▪ Chloride: ≤250mg/l

▪ Sulphate: ≤250mg/l

▪ pH value: 6.5 – 8.5

Measures for desalination, softening or hardness stabilisation are necessary if the filling and top-up water have a high total hardness (>3 mmol/l – total of the calcium and magnesium concentrations, calculated as calcium carbonate). We recommend the use of Fernox KSK limescale and corrosion protector. For other properties deviating from the minimum requirements, suitable conditioning measures are necessary to maintain the required water quality.

Using filling water and top-up water which does not meet the stated quality requirements can cause a considerably reduced service life of the equipment. The responsibility for this lies solely with the operator.

INFORMATION

If an optional external heat generator is connected, these minimum requirements also apply to the filling and supplementary water for this heating circuit.

1.2.6 Heating system and sanitary connection

▪ Create a heating system according to the safety requirements of

EN12828.

▪ The plumbing connection must comply with the requirements of

EN 12897. The requirements of the following must also be observed:

▪ EN 1717 – Protection against pollution of potable water

installations and general requirements of devices to prevent pollution by backflow

▪ EN61770 – Electric appliances connected to the water mains –

Avoidance of backsiphonage and failure of hose-sets

▪ EN 806 – Specifications for installations inside buildings

conveying water for human consumption

▪ and, in addition, the country-specific legislation.

During operation of the indoor unit with an auxiliary heat source, the storage tank temperature may exceed 65°C, above all when solar energy is used.

▪ For this reason, some form of scalding protection needs to be

included when you install the system (hot water mixing device, e.g. VTA32).

INFORMATION

The domestic water quality must comply with the EU Guideline 98/83 EC and the regionally-applicable regulations.

If the indoor unit is connected to a heating system with steel pipes, radiators or non-diffusion-proof floor heating pipes, sludge and chips can enter the hot water storage tank and cause blockages, local overheating or corrosion damage.

▪ To prevent possible damage, install a dirt filter or sludge separator

into the heating return flow of the system (SAS 1 or SAS 2).

▪ The dirt filter must be cleaned at regular intervals.

1.2.7 Operation

The indoor unit:

▪ Do not operate until all installation and connection work is

completed.

▪ Only operate with a completely full storage tank (check level

indicator) and heating circuit.

▪ Operate at a maximum pressure of 3bar.

▪ Only connect with a pressure reducer on the external water supply

(supply line).

▪ Only operate if the protective cover is installed.

The specified servicing intervals should be adhered to and inspection work must be carried out.

1.3 Maintenance, troubleshooting and decommissioning

Work for maintenance, troubleshooting and decommissioning must not be carried out without knowledge of the relevant safety precautions and in the event of disposal of the country-specific guidelines. Please refer to the corresponding information in the reference manual for the fitter.

Recommendations for disposal

We designed the indoor unit in an environmentally friendly manner. During the disposal process, the only waste created is that which can be used for material or thermal recycling. The materials used that are suitable for recycling can be sorted into individual types.
