n Operation
Prior to Operation
Prior to Operation
Preparing for operation
1. Contact an installation specialist for installation.
2. Plug in the power plug properly.
3. Use a dedicated circuit.
4. Do not use an extension cord.
5. Do not start/stop operation by plugging/unplugging the power cord.
6. If the cord/plug is damaged, replace it with only an authorized replacement part.
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 ventilator for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Such usage could damage the
items.
4. This unit cannot control room temperature. If this is needed, do not install the ventilation unit alone, but rather install another indoor unit.
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 ventilator. 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.
Service
For repair and maintenance, contact your authorized service dealer.

2. Contact your dealer if you have any questions.
NOTICE
This note is only applied to model that there is humidity function.
When humidifying fails, the remote controller does not display any error code.
