Connect the piping to each connection point of the module with Housing type
joints (HFUG-2020AN) (see Fig. 3). The maximum fastening power of the
Housing type joints should not exceed 40 Nm. 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 Housing Type Joints
Set-up Guide when using Housing Type Joints. 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 photos. Also, a
check valve is necessary to the air piping to avoid water reverse flow.

Make sure that the module is installed vertically.
If the module is not installed vertically, the effect of
the air scrubbing would be reduced and an
effective filtration will be impaired.
