2. Place the pattern sheet on the ceiling at the spot
where you want to install the indoor unit.
Note : • Since the diagram is made of paper, it may
shrink or stretch slightly due to temperature or
humidity. For this reason, before drilling the
holes maintain the correct dimensions between
the markings.
3. Insert bolt anchors. Use existing ceiling

more than four when installing the indoor unit.

ceiling when suspending the unit. If the ceiling
is already constructed, lay the tubing into
position for connection to the unit before
placing the unit inside the ceiling.

make the base pan be level with the ceiling.
