Prior to operation
ENGLISH
Prior to operation
Preparing for operation
Contact an installation specialist for installation.
Use a dedicated circuit.
Usage
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.
Due to the possibility of oxygen deficiency, ventilate the room when used together with
stoves or other heating devices.
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.
Cleaning and maintenance
Do not touch the metal parts of the unit when removing the filter. Injuries can occur
when handling sharp metal edges.
Do not use water to clean inside the ventilator. Exposure to water can destroy the
insulation, leading to possible electric shock.
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.
