1. Ventilation duct(➂)
Diameter, Ø150 and length, 4m is the requirement and middle duct bending should be less than
once. When using the duct not insulated(spiral, flat duct and etc.), the insulation should be done
and the thickness of the insulation should be more than 13mm.
2. Ventilation fan motor(➅)
The fan motor should have 160CMH of wind, and less than 1A ofoperation current at 15mmAq
and should be installed in the middle of the duct(2m). (This measurement is based on the duct
diameter, Ø150mm and length, 4m) Fan motor should be insulated or the insulation work should
be done and the thickness of the insulation should be more than 13mm.
3. Filter(➄)
Less than 4~5 Mesh recommended.

1. All the components of the duct should be precisely insulated and when connecting
between each component, sealing must be done precisely.
2. The outdoor duct should be installed to bend downward to outdoor, so that rainfalls
couldn't come in. (The inclination should be 1/100 to 1/50)
3. To prevent small animals like birds, mice and etc. or insects, please install net to
the outdoor air inflow inlet.
4. When the metal duct penetrates the wooden wall, please electrically insulate
between duct and the wall. (Please install plastic sleeve and etc. to insulate.)
5. Consider surroundings since the contaminated substances and bad smell from
outside may come inside through the duct.
6. When installing the duct, do not install as below.
1) To bend the duct excessively
• If a wrong fan motor was chosen, decrease of ventilation, damageto the
machine and fire may occur.
• Be sure to use the fan motor with the safety certification specification.
2) To bend the duct too many times 3) To reduce the duct diameter
