on the cassette assembly include:
4- 3/8" Threaded Rods

Procedure for Selecting the Location
• Place above the ceiling where you have
enough space to position the unit.
• Place where the drainage pipe can be
properly positioned.
• Place where the inlet and outlet air of the
indoor unit will not be blocked.
• Do not install the unit in a place with
heavy oil or moisture (e.g. - kitchens and
workshops)
• Do not install in a location with destructive
gas (such as sulfuric acid gas) or pungent
gas (thinner and gasoline) are used or
stored.
• Choose a place solid enough to bear the
weight and vibration of the unit and where
the operation noise will not be amplified.
• Install where there are no expensive items
like a television or piano below the indoor
unit.
• Leave enough space for maintenance.
• Install at least 3 ft. away from televisions
and radios to avoid interference.
