| **** | **Condensate system water-filling test**: After the condensate piping installation is completed, a water-flow test and a water-filling test shall be carried out. The water-filling level shall reach the highest point of the piping; check whether drainage is unobstructed and whether joints leak, so as to ensure there is no hidden water-leakage risk within the hotel ceiling. |
