(2) Ceiling height
This unit can be installed in ceilings up to 3.8 meters high. If the ceiling height exceeds 2.7 meters, how-
ever, the connector of terminal board (A2P) must be replaced and an air outlet blocking pad must be
installed. See HIGH CEILING INSTALLATION (P .13).
(3) If you feel there is danger as a result of investigating whether the place you want to install the unit can hold
its weight, reinforce with a board or beam, etc., before installing. (Because installation pitch is recorded on
the paper pattern for installation, check wheter reinforcement will be required or not along with referring to
the paper pattern.)

(2) Open a hole in the ceiling for installation. (Case of existing ceiling)
• Use the paper pattern for installation which has been adjusted to the dimensions of the ceiling opening.
• Open a hole in the ceiling for installation at the place the unit is to be installed, and run refrigerant and
drain piping, remote controller cord, and outdoor/indoor transmission wiring to the unit's piping and wir-
ing hole. (For wiring procedure, refer to "WIRING EXAMPLE AND HOW TO SET THE REMOTE CON-
TROLLER." For piping procedure, refer to the attached installation manual of the outdoor unit.)
• After opening a hole in the ceiling, reinforcement of the ceiling frame, etc., may be required to maintain
the levelness of the ceiling and to prevent vibration of the ceiling. For details, consult with your builder
and interior contractor.
