008.1444099_01 – 11/2018 – EN
▪ When carrying out any work on the system, switch off the main
switch and secure against being switched on inadvertently.
▪ Seals must not be damaged or removed.
▪ Make sure that the safety valves comply with the requirements of
EN 12828 when connecting on the heating side, and with the re-
quirements of EN 12897 when connecting on the domestic water
side.
1.2.2
Intended use
The indoor unit may only be used for domestic hot water prepara-
tion, as a room heating system and, depending on its design, as a
room cooling system.
The indoor unit must only be installed, connected and operated ac-
cording to the indications in these instructions.
Only the use of a suitable outdoor unit approved by the manufacturer
is permitted.

Permissible combinations
Any other use outside the intended use is considered as improper.
The operator alone shall bear responsibility for any resulting dam-
age.
Intended use also includes compliance with the maintenance and in-
spection conditions. Replacement 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
Device 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 ca-
pacity of the ground of 1050 kg/m
2
plus safety margin is
ensured. The ground must be flat, horizontal and level.
▪
Outdoor installation is not permissible
.
▪ Installation in an explosion-risk environment is not per-
missible.
▪ The electronic control system must not be exposed to
whether effects like rain and snow under any circum-
stances.
▪ The storage tank may not be exposed to continuous dir-
ect 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 to walls and other objects
(
Chap. 4.1
).
▪ Observe the special installation requirements of the R32 refriger-
ant (see
Chap. 4.3.1
).
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 instructions in the DrainBack solar heating sys-
tem manual). An insufficient height difference may lead
to the destruction of the DrainBack solar heating system.
▪ The indoor unit must not be operated in rooms with am-
bient temperatures of more than 40 °C.
1.2.4
Electrical installation
▪ Electrical installations may only be carried out by electrical techni-
cians and in compliance with valid electrical guidelines as well as
the specifications of the responsible energy supply company.
▪ Compare the mains voltage (230 V, 50 Hz) indicated on the name-
plate 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 the heating water
Avoid damage caused by deposits and corrosion: Comply with the
applicable engineering regulations on prevention of corrosion
products and deposits (VDI 2035, BDH/ZVSHK technical information
"Scale formation").
Minimum requirements regarding the quality of filling and supple-
mentary 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-values (heating water): 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, cal-
culated as calcium carbonate). We recommend the use of Fernox
