1)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.

2)Insert bolt anchors, use existing ceiling supports or construct a suitable support as shown in figure.

IMPORTANT ◆ 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.
