Minimum area of clear floor space in the
installation room
Each refrigerant requires a minimum area of clear floor
space in the installation room. No other objects are allowed
to stand in this area. Objects may be hung in this space if
they are installed at a height of at least 0.6 m. (E.g.: buffer
tank, wall shelf)

Note
If the installation area is too small, this can be en-
larged by creating a network of rooms (e.g. door
gap).
WARNING
Do not block door gaps and ventilation openings
used to enlarge the space.

Preparing the electrical connections
WARNING: Electrocution
All electrical connection and installation work must
be carried out according to the applicable national
and regional regulations.
WARNING: Electrocution
Before commencing electrical connection and
installation work, the heat pump system must be
isolated from the power supply.
WARNING: Electrocution
Work on electrical connections and installation may
only be conducted by qualified contractors.
Material damage
This appliance contains frequency converters
(e.g. EC circulation pumps, EC fan motors). Leak-
age currents may arise in normal operation. In the
event of faults, these components may cause DC
fault currents. An incorrectly selected RCD may trip
during normal operation or, in the event of a fault,
may not trip at all or only trip after a delay.
»
Make sure that the power supply for this
appliance is separate from the domestic in-
stallation.
»
Install a type B, AC/DC-sensitive RCD.
