• Caution for installing discharge duct
– Static pressure of the discharge duct should be within the
standard specification when installing the duct.
– If you remove the fan guard to install the discharge duct,
make sure to install a safety net on the duct outlet. Foreign
substance may enter into the product and there could be a
risk of personal injury.
– Wear protection equipment at all times when making
galvanized sheet metal duct, since the worker may get
injured by the sharp parts.
– When installing the outdoor unit under the tree or near
forest, leafs may get into the product and cause problems
on the product. Therefore, install a discharge duct to
prevent foreign substance infiltration.
