Change the fan motor static pressure according to external duct static pressure.
NOTE
• Do not place the connecting duct weight on the indoor unit.
• When connecting the duct, use an nonflammable canvas tie-in to prevent vibrating.
• Insulation foam must be wrapped outside the duct to avoid condensate. An internal duct under layer can be added to
reduce noise, if the end-user requires.
