cabinet
The filters in the base of the wash
cabinet are designed to prevent coarse
soiling getting into the circulation
system.
A build-up of coarse soiling can cause
the filters to clog up. They should,
therefore, be checked daily and
cleaned if necessary.
,The machine must not be used
without all the filters in place.
,Watch out for glass splinters,
needles etc. which could cause
injury.Cleaning the coarse filter
