How to mount outlet pipe.
⚫
Generally, we have two types of outlet pipe
available, i.e. rectangular or round ones.
⚫
Rectangular air conduit can be directly
connected to air outlet of indoor unit by rivets.
For outlet dimensions, see outline drawing of
the unit.
⚫
Round air conduit should be connected to a
piece of transitional air conduit before it is
connected to air outlet of indoor unit, the other
end of it can be separately connected to air
conduit window or connected to air conduit
window after air flow diversion, and the total
length should not be over 6m. As shown in
figure below, air speeds at all air outlets should
be set to basically consistent so as to meet the
room air-conditioning requirements.

be freely adjusted according to height of indoor
