Installation instruction
1. Installation of Duct
2) Sectional shape of duct (mainly has rounded and rectangular two shapes)
16
3) Connecting mode
1)Duct material
Rectangular duct
The dimension of rectangular duct is the same as the air outlet of indoor unit,can be directly connected; the rounded
duct needs to be added with a static pressure box to connect with the air sending outlet of indoor unit; independently
introduced to respective distributor by rounded duct. In order to meet the requirements of room air conditioner,
the fan speed in each air outlet of any distributor shall be adjusted to basically the same.
