To connect to the panel outlet
The quantity of air from the branched duct side is shown in the table below as the air quantity index of the unit. If two
branched ducts are connected to the unit, the amount of air from the branched duct side will be greater and the speed of
the air on the 3-way outlet side will decrease. Therefore, the hot air projection distance will be reduced.

Where the branch duct is installed from this viewpoint, apply the
dimensions indicated in the figure below to avoid accidents.
2
Use ducts with non-combustible insulating materials.
3 Fit enough heat insulation to the duct to avoid condensation.
