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