▪ 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.

Tab. 1-1 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.

1 General safety precautions
CAUTION
▪ Only install the indoor unit if sufficient load-carrying ca-
pacity of the ground of 1050 kg/m
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
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.
jects (Chap. 3.3).
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 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.
CAUTION
▪ The required concentration may vary depending on the
type of glycol. ALWAYS compare the requirements
from the table above with the specifications provided by
the glycol manufacturer. If necessary, meet the require-
ments set by the glycol manufacturer.
▪ The added concentration of glycol must NEVER ex-
ceed 35%.
▪ If the fluid in the system is frozen, the pump CANNOT
start. Mind that if you only prevent the system from
bursting, the liquid inside might still freeze.
▪ If NO glycol has been added to the system and a power
failure or a pump failure occurs, drain the water from
the system.
▪ When the water inside the system is stationary, it can
easily freeze and thus damage the system.
CAUTION
Glycol absorbs water from its environment. Therefore do
NOT add glycol that has been exposed to air. Leaving the
cap off the glycol container causes the concentration of
water to increase. The glycol concentration is then lower
than assumed. As a result, the hydraulic components
might freeze up after all. Take preventive actions to ensure
a minimal exposure of the glycol to air.
CAUTION
Use only propylene glycol including the required inhibitors,
classified as category III as per EN 1717.
