Pictures showing problems during the installation of the FFU

1.The filter lay vertically on the ground. Test verification: The probability of the filter being damaged as a result would exceed 80%.

The filter is damaged as follows::

2、The FFU enclosure and filter were not properly fastened, which inevitably led to air leakage. This would directly result in the wind speed at the filter's outlet surface being significantly lower than the required level, and the wind speed across the cross-section being uneven.

3、If the installation of the ceiling joists is not leveled, it will directly cause the imbalance of the FFU resulting in uneven air velocity at the filter outlet and vibration.

4. The debris on the FFU will be sucked into the interior of the FFU and enter the fan, causing the fan to burn out or break down;
5. Messy or detached power cords and network cables may trip the on-site workers and cause the FFU to lose power or have signal interruption, thus making the FFU unable to operate or unable to be controlled from the terminal computer;
6. After the operation is completed, if the crystal cover on the control box is not fastened properly, it will inevitably lose protection for the power cord interface and network cable interface. After the cleaning package and the Add/A-Plus parties complete their work, the self-control party will finally fasten the crystal cover and tighten the screws.
