duct connection
f Wind the aluminum tape securely around duct connections to prevent any air leak . f
f Try to install indoor side supply air duct and exhaust air duct as far as possible from each other .
f
f aspect ratio should be changed to less than 1:4 when cylindrical duct is changed to rectangular duct .
f
(Duct with less noise: Circular duct > Oval duct > Rectangular duct)
f To minimize noise, we recommend using flexible duct which is made of noise absorption/insulation material . also, length f
of the duct should be minimum 3 m since noise may get louder due to larger volume of air flow when the length of the
duct (between the ERV and the indoor exhaust air inlet and the supply air outlet) is short .
f 2 outdoor side ducts should be installed with declination toward outside, and indoor and outdoor ducts should be f
securely insulated . (Refer to below illustration)
f Duct and external hood installation must comply local ventilation equipment installation standards .
f
f Duct on the outdoor side should be at least 3 m long from the product to prevent rain water from entering to the product f
via duct .
f Motorized damper and Back draft damper should be installed according to damper installation standard for ERV as
f
shown below .
