on the Slim Duct unit include:
4- 3/8" Threaded Rods

Procedure for Selecting the Location
• Place above the ceiling or in soffit area
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.
