Daily Maintenance
Use the BP4610 in a place that meets the installation conditions.
For the installation conditions,
refer to “2.2 Installation Environment”.
If the panel or case surface is soiled, wipe it with a soft cloth. In the case of resistant stains, wipe
with a cloth that has been imbibed with a neutral detergent and then wrung well.
Wiping the BP4610 using an organic solvent such as thinner or benzene, or a premoistened wipe,
may cause degradation in material quality, clouding, or flaking off of the paint, and must
therefore be avoided.
