of the room, and select a suitable location so that uniform air
temperature in the room can be obtained.
• Check to ensure that the foundation is flat, level and
sufficiently strong.
• It is recommended that a service access panel for floor
concealed type indoor units be provided. The access panel
must be fixed with screw(s) so that service engineer(s) only
is accessible.
