3.4 Connecting the condensation draining kit
3.5 Installing the unit on noise-damping supports
While operating, the heat pump is subject to condensation. This will result in a more or less large run-off
of water, depending on the degree of humidity. To channel this ow, we recommend that you install the
condensation drainage kit.
How do you install the condensation drainage kit|?
Install the heat pump, raising it at least 10 cm with solid water-resistant pads, then connect the drainage
pipe to the opening located under the pump.
In order to minimise the noise pollution associated with heat pump vibrations, it can be positioned on
vibration absorbing pads.
To do this, you simply have to position a pad between each of the unit’s feet and its support, and then x
the heat pump to the support with suitable screws.
