(M6 x 12 screws are prepared on site.)
(1) In order to prevent short-circuit air delivery, the piping for air outlet and air return ducts must not be too close.
(2) Before installing the air duct, ensure that the static pressure of the air duct is within the permitted range of the indoor unit (see section 6.2).
(3) Connect the canvas duct to the air return and air outlet ducts to prevent vibrations from the indoor unit transferring to the ceiling.
(4) Use heat insulation materials at a thickness of 25 mm or more to prevent condensation on the air duct.
(5) Connect the air duct as shown in Figure 6.1.
