THSI - Indoor unit positioning

Bear in mind the following aspects when choosing the best site for installing the unit and the relative connections:
• position of the indoor unit next to the main heat source;
• location of power supply;
• solidity of the supporting ceiling / wall.
It is recommended to first prepare holes in the ceiling / wall for the screw anchors.
The dimensions and the positions of the holes for the screw anchors are shown below.
