. The temperature inside the unit increases if dust adheres
to the filter and the ventilation holes are blocked.
Touching inside the unit while it is hot may result in
burn injuries.
. Clean the filter on the rear of the front panel periodically
because the filter tends to gather dust (once every two
months).
Procedure
1. Remove the front panel. (Refer to Section 1-4.)
2. Remove the dust from the filter using a vacuum.
n
If the filter is very dusty, it should be washed in water, and
then dried completely.
2-2. Periodic Replacement Parts to Be
Recommended
The fan used on the rear panel of this unit is periodic
replacement parts to be recommended. The life of the fan
is approximately 50,000 hours. The life corresponds to
about five years and a half if the power is on all the time,
so the fan should be replaced according to service conditions.

available PFV-SP3100 Maintenance Manual.
