4. Maintenance
• If replacement of fuse needed, it is to open the fuse holder at back of the
pump, remove the fuse cover and place the new fuse on. The fuse required is
the quick miniature fuse-links at specification of 2A/250V (Ø5×20).
• The pump is required to make regular cleaning. Use a piece of clean cloth
soaked with proper amount cleanser to clean its surface, and then use a piece
of clean wet cloth to wipe its surface. Finally, dry it with a piece of dry cloth and
place it on a clean rack.
