Prior to operation
Prior to Operation
Preparing for operation
1. Contact an installation specialist for installation.
2. Use a dedicated circuit.
Usage
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.
Cleaning and maintenance
1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling
sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation,
leading to possible electric shock.
3. When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates
at a very high speed during operation. There is a possibility of injury if the unit’s power is
accidentally triggered on while cleaning inner parts of the unit.

Keep the room temperature
uniform.
This is not good for the health
and wastes electricity.
Do not let direct sunshine
enter the room when the air
conditioner is in operation.

in the room.
Make sure that the doors
and windows are shut tight.
Clean the air filter regularly.
Ventilate the room
occasionally.
Avoid opening doors and
windows as much as possible
to keep the cool air in the

cooling and dehumidifying
effects. Clean at least once
every two weeks.
