(1) The default ex-factory return air method is from the back. The return air
cover shall be installed at the bottom of the unit, as is shown in the
following figure.
(2) If the downward return air method is adopted, then install the return air
cover at the back of the unit after dismantling it.
(3) Connect the return duct to the return air inlet of indoor unit with rivet, and
the other side shall be connected to the return air inlet. For the
convenience of free height adjustment, canvas duct can be made and
reinforced with iron wire to a folding shape.

air. For downward return air, silencer and static pressure carton shall be
added to conduct noise reduction treatment.
