Installing the panel
Pull the corner lid toward the direction indicated by the arrow and remove it. (Same way for all 4 corner lids)
Read this manual together with the indoor unit’s installation manual.
Fasten the wiring to the terminal securely and hold the cable securely so as not to apply
unexpected stress on the terminal.
Loose connection or hold will cause abnormal heat generation or fire.
Make sure the power source is turned off when electric wiring work.
Otherwise, electric shock, malfunction and improper running may occur.
Read this manual together with the air-conditioner installation manual carefully.
Check if the opening size for the indoor unit is correct with the level gauge supplied in the indoor unit.
Check if the gap between the plane and the indoor unit is correct by inserting the level gauge into the air outlet
port of the indoor unit. (See below drawing)
Adjust the installation elevation if necessary.
Remove the level gauge before installing the panel.
If there is a height difference beyond the design limit
between the installation level of the indoor unit and the
panel, the panel may be subject to excessive stress
during installation and it may cause distortion and
damage.
