NoteFig.6 only shows the install of rear return air inlet, button return air inlet can also been
installed according to the actual installation need. The method of installation is similar to the rear
return air inlet’s. The supply air duct, which is rectangle or circle and connect with the air inlet of
the indoor unit, should at least keep one open. The circle air duct type should adopt circle
preservation pipe to transmit cool (heat) air to room. The circle air duct should add a transitionary
pipe, which size should match the size of air supply duct of the unit. After connecting the
transitionary pipe, install the circle air outlet vent connection pipe, whose longest length to every
individual air outlet vent should not over 10m. Ducted type indoor unit model 70 can share 3
trainsitional pipe, while model 100,120 can share 4. The transitional pipe, whose straight length is
200, and circle air outlet connection pipe, whose diameter is 200, produced by our company, can
be ordered separately as standard fittings. Model 50 and the model below it do not share circle air
duct. The following is the diagram for install circle air duct.
Note: 1, The longest length of air duct means the general length of the wing supply
pipe to the farthest air supply vent plus the general length of return air duct to the
relative farthest return air vent.
2, To the unit with auxiliary heater, if the circle air duct is need to connected,
the straight length of transitional air duct should not shorter than 200mm.
