Reinserting the
mounting plate
3.3.14 Mounting the collection funnel
The liquid waste from the measuring unit and sample overflow from the overflow
vessels have to be transported out of the housing of the Alyza IQ.
The collection funnel collects the liquids from up to 3 sources (waste tube from
the measuring unit, sample overflow tube from overflow vessel 1 and sample
overflow tube from overflow vessel 2 ) and transports them out of the housing
via a common return line.
To keep moisture and damp air from penetrating the housing of the Alyza IQ, the
collection funnel is closed with a rubber cover. Unused openings of the rubber
cover are closed with plugs.
The collection funnel is installed in the housing of the Alyza IQ at the
second cable gland from the front.

overflow vessels.
