INSTALL THE INDOOR UNIT
When installing optional accessories, read also the
installation manual of the optional accessories.
Depending on the field conditions, it may be easier to
install optional accessories before the indoor unit is
installed (except for the decoration panel). However,
for existing ceiling, install fresh air inlet component
kit and branch duct before installing the unit.
INSTALL THE INDOOR UNIT TEMPORARILY
• Attach the hanger bracket to the suspension bolt.
Be sure to fix it securely by using a nut and
washer from the upper and lower sides of the
hanger bracket.
• Securing the hanger bracket see figure below.

FIX THE PAPER PATTERN FOR INSTALLATION
(FOR NEW CEILINGS ONLY)
• The paper pattern for installation corresponds
with the measurements of the ceiling opening.
Consult the builder for details.
• The center of the ceiling opening is indicated on
the paper pattern for installation.
• After removing the packaging material from
the paper patten for installation, attach the paper
pattern for installation to the unit with the
attached screws as shown in figure below.
1 Paper pattern for installation (on some models)
2 Center of the ceiling openiing
3 Screws (supplied with the decoration panel)
ADJUST THE UNIT TO THE RIGHT POSITION
FOR INSTALLATION.
(Refer to the chapter "Preparation before
installation" on page 7).
CHECK IF THE UNIT IS HORIZONTALLY
LEVELED.
• DO NOT install the unit tilted. The indoor unit is
equipped with a built-in drain pump and float
switch. If the unit is tilted against the direction
of the condensate flow (the drain piping side is
raised) the float switch may malfunction and
cause water to drip.
• Check if the unit is leveled at all four corners
with a water level or a water-filled vinyl tube as
shown in figure below.
