* Lg exhaust Duct Diameter: 100mm
Use the exhaust duct over the inner diameter of exhaust pipe.
Do not use too small inner diameter of exhaust pipe or too long exhaust duct,
Because it makes bad ventilation and low drying performance and it will be cause of
trouble.
Follow the below guide in case of using gathering exhaust duct installed with over 2
duct.
Incline the exhaust duct toward exit about an 45 angle when exhaust duct from dryer
is connected to main exhaust duct. ( If you don't make perpendicular connection,
airflow is disturbed.)
