storage)
● where the humidity range is between 20 and 85% RH (10 to 90% RH in storage, however no

Keep this unit and the power cord away from heaters and heater vents.
Excessive heat could melt the cover or power cord covering, and result in a fire or an electrical shock.
Do not place metal objects or vessels containing liquids on top of the unit.
The entry of any metal object or liquid could result in a fire or an electrical shock.
Do not insert any metal or easily-combustible object inside this unit.
This could result in a fire or an electrical shock.
Do not use flammable sprays inside or near the unit (e.g. when cleaning the
unit).
Such flammable gas may ignite and cause a fire or combustion.
Do not install this unit in a location where there is excessive humidity or where
contact with water is possible.
Poor choice of location could result in deterioration of the insulation, a fire or an electrical shock.
Install this unit on a level, stable stand or floor, with sufficient space around it.
Failure to do so could result in the unit overturning and causing injury.
Disconnect the power plug from the power outlet before attempting to move
this unit.
Failure to do so could result in power cord damage, a fire or an electrical shock.
Always disconnect the power plug from the power outlet when the unit is not
to be used for an extended period.
Failure to do so could result in a fire due to leakage current if the insulation should deteriorate.
