(2) Open the open panel by about 70°.
(3) Connect the electrical cable.
• Be very careful not to confuse the terminal connections. Wrong cabling
may damage the internal control circuit.
• The markings on the indoor unit's terminal board must match with
those of the outdoor unit.
(4) Fix the cable with the accompanying cord holder and the short screw.
(5) Close the open panel.

hose through the piping hole, and hook the unit onto the
mounting plate.
(2) Push the unit and apply the bottom hooking points to the
mounting plate's support. (Take this step after cabling be-
tween the indoor and outdoor units.)
(3) Pull the bottom of the unit to check that the unit is fi xed in
place.
Detaching the unit from the mounting plate
Push the " " marks at the bottom of the indoor unit and
pull the bottom of the unit. When the hooks are released
