NOTES:
1. This kit cannot supply fresh air without connecting a duct from a dedicated outside air system or duct fan.
2. When using this kit with the dedicated outside air system, the maximum fresh air intake volume should be
within 20% of the rated airflow volume of the indoor unit. In addition, when using this kit without the dedicated
outside air system, care should be taken to not cause condensation inside this kit, the duct, and indoor unit.
3. The total height of the unit is increased by approximately 2-3/16 inches (55mm) when the fresh air inlet kit is
installed. Pay attention to the amount of space needed for installation.
4. When fresh air is taken from one side, cover the gap with insulation for the other side to prevent air leakage
and condensation.
5. Air flowing through the duct does not pass through the air filter of the indoor unit. Therefore, install an air filter
(field-supplied) at the supply side of the fresh air.
6. Insulate the duct and the duct connection (including the plate band and the T-tube connection).
The materials for the duct and the insulation should be nonflammable.
7. The curve "Pass Resistance of Fresh Air Intake Portion" shows the value when the kit is used by itself. If the
kit is installed along with the T-tube connecting kit, refer to the "T-Tube Connecting Kit" for details.
8. Refer to the "Installation Manual for Fresh Air Intake Kit" for installation details.
