5.6 Watertightness Test and Water Flow Test
Once installation of a drainage piping system is complete, watertightness and water flow tests should be performed.
Notes for installers
Watertightness test
 Fill the piping with water and test for leakages over a 24-hour period.
Water flow test (natural drainage test)
 Slowly fill the drainage pan of each indoor unit with at least 600ml of water through the inspection port and check
that the water is discharged through the outlet of the drain piping.
Caution
 The drain plug in the drainage pan is for removing accumulated water prior to performing indoor unit
maintenance. During normal operation, the drain should be plugged to prevent leakage.
