droplets (condensation) may form on the unit surface. If water
droplets form, immediately wipe them off with a soft cloth. If
water droplets are left on the unit, they may be absorbed into the
wooden parts, causing deformation.
• When cleaning the unit, use a dry, soft cloth. Using chemicals
such as benzine or thinner, cleaning agents, or chemical
scrubbing cloths can cause discoloration or deformation.
