Material losses
If the temperature at the installation site could continu-
ously fall below freezing (1-2 days) you should install
a condensate pan heater. The condensate pan heater is
not part of the standard delivery.
When the compressor is running, install a load-dependent relay
to switch on the condensate pan heater after a delay.
The condensate pan heater must have an external power supply.
10.3 Electrical connection
WARNING Electrocution
The appliance is supplied with a flexible power cable
without plug. In the case of a permanent connection,
the appliance must be able to be separated from the
power supply by an isolator that disconnects all poles
with at least 3mm contact separation. Contactors, circuit
breakers or fuses can be used for this. This type of iso-
lator must be installed in the fixed electrical installation
according to the regulations.
For Australia: Ensure that the appliance can be separated
from the power supply by a suitable isolator. Contac-
tors, circuit breakers, fuses or general purpose power
plugs can be used for this. This type of isolator must be
installed according to the electrical installation regu-
lations.
WARNING Electrocution
Carry out all electrical connection and installation work
in accordance with national and regional regulations.
WARNING Electrocution
Ensure that the appliance is connected to the earth con-
ductor.
WARNING Electrocution
Observe the safety measures to prevent contact with
dangerously high contact voltage.
WARNING Electrocution
Coming into contact with live components presents a
threat to life. Disconnect the appliance from the power
supply before carrying out work on its interior. Prevent
the power supply from being switched on while you are
working on the system.
WARNING Electrocution
Insufficient earthing can lead to electrocution. Ensure
the appliance is earthed according to locally applicable
requirements.
WARNING Electrocution
If the power cable is faulty, replace it with a new one.
The power cable should only be replaced by a qualified
contractor.

Material losses
Install a residual current device (RCD).
!
Material losses
The specified voltage must match the mains voltage. Ob-
serve the type plate.
!
Material losses
Observe the fuse protection required for the appliance
(see chapter "Specification/ Data table").
!
Material losses
Never connect the appliance to the power supply before
the DHW cylinder is filled.
The appliance is supplied with a flexible power cable without plug.
 If the power cable is not long enough, you may disconnect it
from the appliance and replace it with a longer, more suita-
ble cable. Alternatively, you may extend the cable as permit-
ted by regional and national regulations (e.g. with the use of
a junction box).
 When routing the new power cable, ensure waterproofing
where it passes through the existing cable grommet. Connect
the cable properly inside the appliance.
