■
The gradient of the condensate water pipe shall keep over 1%.
■
The condensate water pipe shall be thermal insulated.
■ When installing the ceiling Conceal indoor unit, the air return duct must be designed and installed as figure
shown.
Note:
■
When connecting the short ducts, use the low static terminals, which color is white.
The distance L from the air outlet of the duct to the air outlet of the air conditioner shall be no more than 0.5 m.

1. Installation of air sending duct
■
This unit uses rounded duct, the diameter of the
duct is 180mm.

The rounded duct needs to add a transition duct
to connect with the air-sending duct of indoor unit,
then connect with respective separator. As Figure
shown, all the fan speed of any of the separator's
air outlet shall be adjusted approximately the same
to meet the requirement for the room air conditioner.
2. Installation of air return duct
■
Use rivet to connect the air return duct on the air
return inlet of the indoor unit, then connect the other
end with the air return blind as Figure shown.
3. Thermal insulation of duct
■
Air-sending duct and air return duct shall be
thermally insulated. First stick the gluey nail on the
duct, then attach the heat preservation cotton with
a layer of tinfoil paper and use the gluey nail cap to
fix. Finally use the tinfoil adhesive tape to seal the
connected part. As Figure shown.
