Devices for external installation must be placed on a level concrete foundation (chapter 4.2.5). For exact
position and dimensions of pipe connections, see technical data (chapter 7). Along with pipes for the
hydraulic connection, install also pipes with wire rope (it is advisable to separate the power / sensors).
Use this wire rope to lay the two external device’s power cables and the jacketed communication cable
from the utility room. The recommended diameter of this pipe is given in the table below and depends
on the dimension of the power cable.

For the appropriate diameter of the power cable, see technical data (chapter 7.2).
Make a sink for the condensate forming in the evaporator of the device underneath the concrete
foundation. The sink must be under the frost limit to ensure unobstructed drainage.
Sink in installations V1 or V2
When installing the pedestal, the installations V1 and V2 can be chosen according to the connection
with the utility room.
