Waste/aspiration hoses
The sample residue can be aspirated and collected
separately from the receiver waste. For this purpose a
separate collection tank is necessary. For joint disposal
of the sample tube and the receiver waste the delivered
y-piece is used to guide the two hoses into one hose. All
connections must be secured by clamps.

The collection tank must be located lower than the
device to guarantee proper drainage.
Connect the waste hose to the waste outlets and secure
them with clamps. The hose must be cut to appropriate
length. The drain hose is then connected to the tank,
by means of the straight connector and the screw cap
including the sealing.
Alternatively the waste hose can also be guided into the
sink.
