14) The long drainage pipe may be fixed by using hanger bolts, thus to ensure a gradient of 1/100 (PVC
cannot be bent).
The spacing between the supports of horizontal pipe is 0.8-1.0m. Twisting will be caused and thus air bag
will be formed if the spacing is too high. Once the air bag is formed, the pump can only compress the air bag no
matter how forcible it pushes, but there is no flowing water, thus resulting in abnormal water level. This will cause
flooding of the ceiling.
15) If the air flow of indoor unit is high, this might cause negative pressure and result in return suction of
outdoor air. Therefore, U-type water trap shall be designed on the drainage side of each indoor unit.
Install water trap as shown below;
Install one water trap for each unit.
Installation of water trap shall consider easy cleaning in the future.
