The diameter of connecting gas side on the indoor unit is 22.2, and therefore
please use the accessory joint for installation.

<Installation Notice>

1. Be sure to set a check port at the right of air discharge port.

2. Set to slope the drain piping downward at 1/100 and be sure to set a drain trap
on its way as shown below figure.

3. Please avoid the installation on the place where oil disperses or is shrouded by
oil smoke, such as kitchen or mechanical factory.

4. Indoor unit does not have air filter its inside. So be sure to set an air filter (local
arrangements) in the position maintained easily such as a suction grills. (If there
is no air filter, dusts are blocked in the air heat exchanger and it may cause
failure or water leak in air-conditioner.)

5. Please hang the main unit horizontally.
