6 Overview
About the solid waste compartment
The solid waste compartment is made of a solid metal bin
that is firmly connected with the wash/waste drawer.
One waste bag with insert can be inserted into the
compartment. It is fixed by means of a fastener.
About the solid waste bag with insert
The solid waste bag with insert is autoclavable and
contains a cardboard insert.
The cardboard insert must be unfolded before use. It
ensures that the maximum waste volume is used due to
the optimal placement of the bag within the
compartment. It also prevents the bag from being pierced
with sharp waste items.
