PFX2000 Maintenance 4-3
• Clogged dust fi lters hinder the cooling of the inside of the unit and can
cause malfunction and shortening of the service life.
1. Remove the dust fi lter by referring to Fig. 4-2.
2. Remove the dust on the fi lter such as by using a vacuum cleaner.
If the fi lter is extremely dirty, clean it using a water-diluted neutral detergent
and dry it completely.
• When the charge/discharge power unit is in operation, air is sucked
through the dust fi lter to cool the unit. If moisture is included in the fi lter,
the temperature or humidity inside the unit increases and may cause a
malfunction.
3. Attach the dust filter (louver) to its original position.
