Connect the piping to each connection point of the module with Housing type
joints and screw (HFU-B2315AN) (see Fig. 3). For the screw, use plastic
connection and tighten by hand power. When you tighten or loosen the
Housing type joints, make certain to maintain sufficient space prior to the work
and be careful not to be wounded by swinging out or clipping your fingers.
Keep the connection surface free of any dirt or
oils.
Follow the instruction of the connection submitted
by the supplier. A wrong use may cause the
damage to the module.

Air inject should be located just beneath the bottom nozzle of the module to
inlet air completely to the module. Please refer to the below figure. Also, a
check valve is necessary to the air piping to avoid water reverse flow.
Make sure air tubes or pipings are properly
fixed. Otherwise, the tubes or pipings may
blow away or behave violently during air
scrubbing.
