z Wrap both the inlet-side and outlet-side flange and
the duct connection area with aluminium tape for
something similar to prevent air escaping.
z Please attach an air filter inside the air passage on
the inlet-side. (Use an air filter which duct
collection efficiency (in a gravimetric technique) is
higher than 50%)
z Be sure to insulate the duct to prevent condensate
water from forming. (Material: glass wool or
polyethylene foam, above 25mm thickness)
z Duct pressure drop of YDCC06~18/YDCC018~053
indoor unit models cannot be higher than 30 Pa;
YDCC25~45/YDCC066~115 indoor unit models
cannot be higher than 80 Pa;
YDCC50~60/YDCC140~175 indoor unit models
cannot be higher than 100 Pa.
z The air outlet cannot be too high and be positioned
at the place where it directly blows the people for a
long period.
z To reduce vibration and noise, it is better to use
flexible connection to connect the air inlet and
outlet duct with indoor unit.
