Prior to operation
Prior to operation
1. Contact an installation specialist for installation.
2. Connect the power cable between indoor unit and outdoor unit properly.
3. Use a dedicated circuit.
4. If the cord/plug is damaged, replace it with only an authorized replacement part.
1. Being exposed to direct airflow for an extended period of time could be hazardous to your health.
Do not expose occupants, pets, or plants to direct airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or
other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g. preserving precision
devices, food, pets, plants, and art objects). Such usage could damage the items.
1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when
handling sharp metal edges.

uniform.
Adjust the vertical and horizontal
airflow direction to ensure a
uniform temperature in the room.
Make sure that the doors and
windows are shut thight.
Avoid opening doors and windows
as much as possible to keep the
cool air in the room.
Clean the air filter regularly.
Blockages in the air filter reduce the
airflow and lower cooling and
dehumidifying effects. Clean at least
once every two weeks.
Ventilate the room
occasionally.
Since windows are kept closed, it
is a good idea to open them and
ventilate the room now and then.
