b) The steel-plate ventilating duct is designed based on the unit and engineering requirement,
and is installed properly according to the engineering standards.
c) Based on the unit dimensions and the size of steel-plate ventilating duct, prepare materials
such as canvas casing, tin foil, steel bar and tapping screw, as well as tools such as
hand-operated electric drill, air screw driver and screwdriver.
3) Basic operation of connecting an ODU to static pressure ventilating duct
Two methods are available to connect an ODU to static pressure ventilating duct.
Method 1:
a) Install the ODU (2) and steel-plate ventilating duct (1). Use an air screw driver or
screwdriver to unfasten the tapping screws that fixing the top case component (3), and
then remove the top case component. Take out the grille from the top of the top case
component and leave the top case.
b) Put the canvas casing inside out (4). Cover one end of the canvas casing over the unit
downward until the canvas end face is aligned with the unit or a bit higher than the top of
the unit. Then, put the top case back (3) and tightly press the canvas casing (4). Use
tapping screws to fix the top case onto the unit (3).
c) Pull up the canvas casing reversely (4) and use the steel bar (5) to press the canvas
casing tightly onto the counter flange of the steel-plate ventilating duct (1). Use a
hand-operated electric drill to drill holes and fasten the parts by using tapping screws.
d) Use the tin foil to seal the joints and check the joints' reliability.
