(4) Installation
(a) Selecting the installation place
● Any obstacles should be cleared out of the periphery and within 30 cm under the moving range of the air inlet grille.
Request
● You cannot move the grille up and down if you have installed the panel before receiving the power source.
● When enclosing the grille before receiving the power source, it can be fixed provisionally using the attached stopper.
● After receiving the power source, confirm that the attached stopper is disengaged before making up and down movements.
Note(1) If you attempt to move it up and down with the attached stopper engaged, it could cause trouble by entangled
wires.
● When operating the grille for the first time after installation, use the remote controller and make the "Up" movement so as
to enclose the grille in the regular position. (Microcomputer memorizes the enclosing position.)
● When the power source is turned on with the grille brought down, you can operate the air conditioner. However, you
cannot operate the air conditioner if the grille is down after completing the enclosing operation.
● When the outlet louver cannot be operated with the remote controller, check if connectors are connected properly or not
and then turn the power source off for more than 10 seconds before turning the power source on again.
● Carefully handle the wires avoiding damages by bending, twisting, pinching, etc. or burn by cigarette, etc.
(b) Confirmation of unit mounting level
1) Using the level gauge packed together with the air conditioner
unit, confirm that the height of unit and dimensions of opening
on the ceiling are correct.
2) Check the mounting level of the air conditioner unit and the ceiling
material.
3) Attach the level gauge supplied as an accessory of air conditioner
unit, and fix the mounting height of the unit.
4) Remove the level gauge before mounting the panel.
(c) Directions of unit mounting and air inlet grille
1) Mounting directions of the unit and the panel are specified.
a) Align the directions of the receiver and the refrigerant piping.
b) Check the connecting direction of connectors. (See (e) Panel installation for details.)
2) Panel and air inlet grille have no specific directions.
a) Wire hook positions for four directions are provided at the same place.
b) Fix wires both at opposing sides. (See (f) Installing the air inlet grille for details.)
(d) Setting the descending length
1) Confirming there is no obstacle within the range of the descending length plus 30 cm, determine the descending distance.
Attach by aligning with the
face of the air outlet.
