1
Place the pattern sheet on the ceiling at the spot where you want to
install the indoor unit.
2
Insert bolt anchors, use existing ceiling supports or construct a suitable
support as shown in figure.
3
Install the suspension bolts depending on the ceiling type.
4
Screw eight nuts to the suspension bolts making space for hanging
the indoor unit.
5
Check the level of the indoor unit by using a leveler or a vinyl tube filled
with water.
◆
A tilt of the indoor unit may cause malfunction of a built-in float switch and
water leaks.
6
Adjust the height of the indoor unit by using the gauge of dimensions.
◆
The air inlet side should be slightly higher than the air outlet side
(approx. 5mm). The appropriate height from the ceiling surface is 25mm
for the air inlet and 20mm for the air outlet.
◆
You should adjust the gauge of dimensions and the pattern sheet to fit
the cutting dimensions of ceiling.
◆
Make sure that the indoor unit is installed at a level if the indoor unit
slants too much, there can be water leaks.
7
Tighten the upper part nuts.
8
Remove the gauge of dimensions after installing the indoor unit.
◆
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.
◆
If the length of suspension bolt is more than 1.5m,
it is required to prevent vibration.
