13.1 Before Installation
Please check whether the accessories are of full scope. If there are some fittings free from use, please
restore them carefully.
13.2 Installation space
(Refer to fig.1, fig.2, fig.3 and table 1 for specification.)
The indoor unit should be installed in a location that meets the following requirements:
 There is enough room for installation and maintenance.
 The ceiling is horizontal, and its structure can endure the weight of the indoor unit.
The outlet and the inlet are not impeded, and the influence of external air is the least.

 The air flow can reach throughout the room.
 The connecting water pipe and drainpipe could be extracted out easily.
There is no direct radiation from heaters.

Caution:
Keep indoor unit, outdoor unit, power supply wiring and transmission wiring at least 1 meter away from
televisions and radios. This is to prevent image interference and noise in those electrical appliances. (Noise
may be generated depending on the conditions under which the electric wave is generated, even if 1 meter
is kept.)
13.3 Installation procedures for fresh air intake duct connection
Preparing the connection hole
 Cut off the knockout hole on the side plate with a nipper.
Cut the inner insulation of the hole portion with a cutter.

Placing the insulation
 Put the insulation tightly around the hole of the unit as shown. The ends of the side plate and the inner
insulation must be completely adhered without leaving any clearance along the circumference of the
hole. Make sure the inner surface of insulation tightly contacts the inner insulation edge and the side
plate. (refer to fig.5)
13.4 Install the Main Body
A. The existing ceiling (to be horizontal)
a. Cut a quadrangular hole of 880×880mm in the ceiling according to the shape of the installation paper
board.
 The center of the hole should be at the same position of that of the air conditioner body.
 Determine the lengths and outlets of the connecting pipe, drain pipe and cables.
