Notes On Drilling Hole In Wall
You must drill a hole in the wall for the
refrigerant piping, and the signal cable that will
connect the indoor and outdoor units.
1. Determine the location of the wall hole
based on the location of the outdoor unit.
2. Using a 65-mm core drill, drill a hole
in the wall.
NOTE: When drilling the wall hole, make
sure to avoid wires, plumbing, and other
sensitive components.
3. Place the protective wall cu in the hole.
This protects the edges of the hole and
helps seal it when you nish the
installation process.
When selecting a 7.0kW Indoor Unit
The 7.0kW indoor unit can only be connected with
an A circuit. If there are two 7.0kW indoor units,
they can be connected with A and B circuits.
