There is a cooler built into this appliance variant.
By using an external cooling unit, the working temperature can be
lowered in relation to the room temperature (depending on the
supply temperature).
The cooler is connected to an external cooling unit (e.g. IKA KV
600) via the plug connection at the back of the appliance. The inlet
and outlet connections are labelled accordingly at the back of the
appliance. To connect the cooling pipes there are two hose
connection pieces included. They can be connected to a hose with
a 10mm interior diameter. The connectors are unlocked by coaxi-
ally positioning the unlocking lever and pressing slightly in the
direction of the arrow. By positioning and light pressure in the
direction of the plug, the connectors are locked/connected to the
inlet/outlet plug connections on the housing.
