Check the level of the indoor unit by using a leveler or a vinyl tube filled
with water.

water leaks.

Adjust the height of the indoor unit by using the gauge of dimensions.
N You should adjust the gauge of dimensions and the pattern sheet to fit
the cutting dimensions of ceiling.

Tighten the upper part nuts.

Remove the gauge of dimensions after installing the indoor unit.
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; refer
to pages 11~13.
N Ensure that the ceiling is strong enough to support the
weight of the indoor unit.
Before hanging the unit, test the strength of each
attached suspension bolt.
N If the length of suspension bolt is more than 1.5m, it is
required to prevent vibration.
N If this is not possible, create an opening on the false
ceiling in order to be able to use it to perform the
required operations on the indoor unit.
You must install the suspension bolts more than four
when installing the indoor unit.
