Testing of Drainage System
‹ After the electrical installation is completed, carry out the testing of the drainage system.
‹ During the test, check if the water correctly flows through the pipelines. Carefully observe the joints to
ensure that there is no leakage. If the unit is to be installed in a new house, carry out testing before decorating
the ceiling.
3 ） Matters of Attention
‹ The drain pipe outlet direction can be chosen from either the right rear or right.
The diameter of the drain pipe should be equal to or greater than the diameter of the connecting pipe. (Vinyl
tube; pipe size: 20mm; outer dimension: 26mm)
Keep the drain pipe short and incline downwards at a gradient of at least 1/100 to prevent air pockets. (Refer
to Figure 1-2-10)
Figure 1-2-10
‹ No folding of drain hose inside the indoor unit. (Refer to Figure 1-2-11)
‹ Confirm that smooth drainage is achieved after the piping work. Pour 600 cc of water into the drain pan from
the air outlet for confirming drainage. (Refer to Figure 1-2-12)
