Air conditioner is poor in cooling (or heating) effect. |
| • | Is temperature setting proper? ( | Refer to Page 7) | ||
|
| • Is the air inlet or outlet of outdoor unit blocked? | ||||

|
| • Connection of indoor unit drain pipe is leaking. | ||||
|
|
|
| |||
Water leaks from outdoor unit. |
| • | Under cooling mode, water might condense on pipe | |||

| ||
|
| • Defrosted water flows out under heating or defrost | ||||
|
|
| (auto defrost) mode. |
| ||
