5. Connect the piping to each connection point of the module with Housing type
joints (HFU-2020AN, HFU-1020AN) (see Fig. 4). 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.
6. 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.

7. 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.
