ATTENTION
Danger of damage to building or risk of slipping in the floor area
In the cooling mode, a drop below dew point can cause condensation of moisture from the air on
the surface of the heat transfer systems. This can damage the building or pose the risk of slipping
in the floor area.
► Prevent the temperature from dropping below the dew point by suitable placement of dew
point sensors.
► Alternatively, the condensate that forms can be safely drained.
► In addition, insulate the pipes concerned to prevent diffusion.

Bi-bloc system
The bi-bloc system consists of an outdoor unit installed in the open air and an indoor unit, either
standard hydrokit or All in One unit, which is usually installed in the boiler room or in another frost-
free room. The two units of a bi-bloc system are linked through refrigerant pipes, so there is no
danger of freezing. The heat pump is operated through the operating panel on the indoor unit.
The All in One unit is a space-saving combination of the hydrokit and a high-quality stainless steel
hot water tank. It can be installed quickly and smoothly, because the internal pipes of the device
unit are already laid and the pipe connections are placed on the underside of the device.
Mono-bloc system
The mono-bloc system consists of one single unit that is set up outdoors. No refrigerant pipes
are needed for the installation; only the heating system needs to be connected to it. Mono-bloc
systems are easier to install, but need more space. Moreover, as the heating water leaves the
building envelope, it can freeze in the event of power failure or if the electricity supply is cut off by
the network operator.
The heat pump is operated by using the wired remote controller, which is placed in the building and
is linked to the mono-bloc unit with a cable of max. 15 meter length.
