The rated cooling performance is tested under non-drainage status.
Make sure that water will not leak from the surrounding area when rubber plug and joint were used. Please seal it in case
leakage is found.
If you choose non-drainage when cooling, both the bottom and the back drain holes of the unit should be plugged with rubber
plugs. The condensed water will be sprayed to condenser, and will improve the cooling performance.
When you choose non-drainage, the air conditioner will be perfect cooling efficiency, but big noise may be caused by spr-
aying the condensed water. Please do not choose it if you are sensitive to the noise.
