Maintenance
■ Regular care
Disconnect the power cable from this unit before starting regular
care. Clean the housing of this unit with a soft cloth. If heavily
soiled, use a damp cloth with a mild detergent and then wipe with a
dry cloth again. Do not use strong detergents or solvents such as
alcohol or thinner to prevent from damaging the finish or shape of
the unit. When cleaning the housing, do not directly touch or rub
the lens.
■ Cleaning the filter
If dust has accumulated on the filter attached in the ventilation slot,
the air does not circulate well and the temperature inside this unit
will rise. This may cause damage to this unit. Clean the filter every
200 hours. If you find difficulty clearing the dust, replace it with
new one.
1. Turn off the power and disconnect the power cable
from this unit.
2. Pull down the filter holders located on the rear of this
unit. Remove the filter frame by pulling it toward you
and then downward.
3. Remove the wire remains placed inside the filter
frame that snaps into place behind four tabs. Then
remove the thin sponge filter from both sides.
4. Carefully clean and wash the removed filters to
eliminate accumulated dust.
5. After the cleaned filters are completely dry, put them
back on this unit. If they are not refitted correctly, the
lamp will not turn on.
Important
• If the filter is heavily soiled, replace it with the new one
supplied.
• When you need more filters for replacement, contact the
store where this unit was purchased.
