(See figure 3)
Indoor unit installation
When installing optional accessories (except for the air inlet panel),
read also the installation manual of the optional accessories.
Depending on the field conditions, it may be easier to install optional
accessories before the indoor unit is installed.
1 Install the indoor unit temporarily.
- Attach the hanger bracket to the suspension bolt. Be sure to
fix it securely by using a nut and washer from the upper and
lower sides of the hanger bracket.
(See figure 4)
2 Check if the unit is horizontally levelled.
- Do not install the unit tilted. The indoor unit is equipped with a
built-in drain pump and float switch. (If the unit is tilted
against condensate flow, the float switch may malfunction
and cause water to drip.)
- Check if the unit is levelled at all four corners with a water
level or a water-filled vinyl tube as shown in figure 9 .
3 Tighten the upper nut.
Installing the duct
Connect the duct supplied in the field.
Air inlet side
- Attach the duct and intake-side flange (field supply).
- Connect the flange to the main unit with accessory screws
(7).
- Wrap the intake-side flange and duct connection area with
aluminum tape or something similar to prevent air escaping.

When attaching a duct to the intake side, be sure to attach
an air filter inside the air passage on the intake side. (Use
an air filter whose dust collecting efficiency is at least 50%
in a gravimetric technique.)
The included filter is not used when the intake duct is
attached.
