and may pose a hazard.
• If the unit is not level, the damper unit will not
work properly.

Duct Installation
• Duct installation is necessary to protect against access to live parts, rain water or contact with moving parts.
• Seal the junction of an adaptor and a duct with an aluminium tape firmly to prevent any air leakage.
• The room intake opening should be positioned as far as possible from the indoor supply opening.
• Use the specified ducts. (See the Model List)
• Install two outdoor ducts so they will be in the down gradient toward outdoor to prevent water from coming in.
(Gradient: 1/100~1/50) (See the figure below)
Heat-insulate two outdoor ducts (including outdoor air and exhaust air duct) to prevent dewing.
(Material: Glass Wool, Thickness-25mm) (See the figure below)
To pierce the metal duct through the metal lath or the wire lath or the metal plate of the wooden facility, insulate
electrically between the duct and the wall. (Refer to the laws and regulations of the country concerned and the
technical standard.)

• It is recommended that an electric damper is used together with the Air to Air Heat Exchanger, as wind may enter
the room while the unit is not in operation in windy places.
