air vents to avoid damage to the inner parts of
the appliance.
Never submerge the appliance in water or any
other liquid or place it under running water.
If the appliance is not in good condition of
cleanliness, its surface may degrade and
inexorably affect the duration of the appliance's
useful life and could become unsafe to use.
Remark: When the appliance is used as a
heater after long periods in storage or after
having been used solely as a fan a small
amount of smoke may be produced. This is
not important and is due to the heater burning
dust deposits which have accumulated on the
heating element. This phenomenon may be
avoided by cleaning the inside of the appliance
beforehand through the grill with a vacuum
cleaner or pressurised air.
