Prior to Operation
Prior to Operation
Preparing for Operation
1. Contact an installation specialist for installation.
2. Use a dedicated circuit breaker.
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.
