When installing the indoor unit in a semi-concealed orienta-
tion, make sure to reinforce the insulation of the unit on all
sides. Drops of water may fall from the unit if it is not thor-
oughly insulated.
• In order to check the drainage, be sure to use a level dur-
ing installation of the indoor unit. If the installation site of
the indoor unit is not level, water leakage may occur.
