4COMFIRMING THE INSTALLATION

After the installation completes, perform the test run to confirm that no abnormality is found.

For your future reference, please keep the installation manual on your side.

Duct connection and installation

CAUTION

• The outside air should be processed by the heat exchanger, etc.

(The outside air temperature range after processing: 54°F to 86°F (12°C to 30°C)

• Be sure to install the return duct.

• The duct fan for the outside air introduction shall require the interlock wiring.

• The sound insulation chamber shall be required to prevent from occurring the operating sound.

• The connection duct is not supplied with the product. Please procure Ø3.9” (100 mm) flexible duct on the market.

1Mounting the connection duct

Set the flexible duct to the external side of the flange

circle and fix it by using a band at 1” to 1.2” (25 to 30

mm) position from the edge of the flexible duct.

2Sealing the connection port

• Wrap the tightening band with the heat insulating

materials of 0.79” (20 mm) thickness or more.

• Apply the adhesive tape around the heat insulating

materials of the connection port to prevent the heat

insulating materials from peeling off.

CAUTION

• Seal the connection port without any clearance to

prevent from dew condensation.

• Keep the thermal insulation around the duct and the

connection port.

(If the thermal insulation is not applied, the dew

condensation may occur due to the temperature

difference between the outside air and the air staying in

the ceiling.)

• Confirm the sound insulation chamber is installed.

4Duct fan wiring

• The interlock wiring should be applied between the duct fan and the indoor unit ventilator.

Insert the connector to CN60 on the main P.C. board of the indoor unit and connect the duct fan driving relay

(DC12V).

The thick line ( ) shows the connection circuit.

• After installing the duct, perform the test run to confirm whether the duct fan and the ventilation of the indoor

unit work starting or stopping at the same timing. (For the test run, following to the instructions described on
