center of the hole. Another method is by putting measuring tape at position as shown in the diagram above.
The hole center is obtained by measuring the distance namely 128 mm for left and right hole respectively.

TO DRILLA HOLE IN THE WALL AND INSTALL A SLEEVE OF PIPING
1. Insert the piping sleeve to the hole.
2. Fix the bushing to the sleeve.
3. Cut the sleeve until it extrudes about 15 mm from
the wall.
When the wall is hollow, please be sure to use the sleeve
for tube assembly to prevent dangers caused by mice biting
the connecting cable.

WIRING
As to main power source and cable size of outdoor unit, read the installation manual attached to the outdoor unit.
Warning
The units must be installed in accordance with applicable national and local regulations.
The units installed by a professional installer must be supplied from a dedicated electrical circuit.
All electric work must be carried out by a qualified technician according to proper technical standards for electrical work and
according to installation manual for installation work.
If circuits with insufficient capacity are used, or if electrical work is not carried out properly, electric shocks or fire may result.

according to installation manual for installation work.
If circuits with insufficient capacity are used, or if electrical work is not carried out properly, electric shocks or fire may result.
Caution
Be sure to install a current leakage breaker or circuit breaker to the main power supply, otherwise electric shocks may result.
Caution
Be sure to connect the unit to secure earth connection. (with a earth resistance of 100
ȍ or less).
If the earthing work is not carried out properly, electric shocks may result.
Warning
Wiring shall be connected securely using specified cables and fix them securely so that external force of the cables may not
transfer to the terminal connection section. Imperfect connection and fixing leads to fire, etc.
