10.7 Condensate drain
A hose is fitted at the factory to the defrost pan to act as conden-
sate drain. The hose terminates near the knock-out on the bottom
plate to the right of the refrigeration drive.
!
Material losses
Ensure the hose is not kinked. Route the hose with a
slope. The condensate must be able to drain freely.
Use a suitable condensate pump if there is insufficient fall. Observe
the delivery head of the building.
If using a condensate pump, ensure that it is designed to deliver
at least 6l/min.
Outdoor installation
Route the hose downwards out of the appliance. The conden-
sate hose can also be routed out of the appliance to the right
through the knock-out in the side panel.
Channel the condensate into a drain or allow it to drain into a
coarse gravel soakaway. Ensure the pipework is free from the
risk of frost.
If required, you may install a ribbon heater on the condensate
hose. We recommend that you install a ribbon heater if the rout-
ing of the condensate hose means it is at risk of frost or is fully
exposed to the elements. The ribbon heater is switched on at a
temperature < 0°C.
Observe the chapter "Electrical connection".
Indoor installation
Route the condensate into a drain. For this, route the hose
through an opening in the floor plate and frame (see chapter
"Installation / Siting and connecting the appliance / Indoor
installation"), and route it out of the appliance to the right by
removing the knock-out in the bottom of the side panel.
In the following diagram the position of the knock-out for the
condensate hose can be seen.

10.8 Second heat generator
For dual mode systems, always connect the heat pump into the
return of the second heat generator (e.g. oil boiler).
10.9 Checking fans
Incorrect transport can slightly shift the fan, resulting in the fan
impeller dragging on the inlet nozzle.
If required, move the fan retainer to the left or to the right in its
slots.
The height can be adjusted by a corresponding rearrangement
of the spacer brackets from the top to the bottom of the retainer
or vice-versa.

11.1 Control panel
WARNING Electrocution
Before working on the appliance, isolate it from the
power supply at the control panel.
Terminals are located inside the appliance control panel and be-
come accessible by removing the front panel.
Observe the information in chapters "Preparations / Electrical
installation", "Installation / Outdoor installation" and "Instal-
lation / Indoor installation".
Remove the control panel from the casing.
Use appropriate electrical cables in accordance with local
regulations.
Check the function of the strain relief fittings.
Connect the heating circuit pump to the heat pump manager
in accordance with the technical guides.
