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.
1
Mounting 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.
2
Sealing 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.)
