2.4 Installation of Air Duct

NOTES！
① There should be insulating layer on air-out duct, air-return duct and fresh air duct to
avoid heat loss and moisture. Adhere a nail on the air duct and then add thermal
sponge with a layer of tin. Fasten it with a nail cover and then seal the junction with
tin tapes. You can also use other materials that have good insulation quality.
② Each air-out duct and air-return duct should be fixed on a pre-made board with iron
frame. The junction of air duct should be well-sealed in order to prevent air leakage.
③ The design and construction of air duct should comply with national requirements.
④ The edge of air-return duct is suggested to be more than 150mm(5-7/8 inch.) away
from the wall. Add a filter to the air-return opening.
⑤ Please consider noise-damping and vibration damping for the design and
construction of air duct. Besides, noise source must be away from people. For
instance, do not have the air-return opening installed on top of the user (Offices, rest
area, etc.).
