WARNING
The metering hoses must always be disconnected from the relevant canisters
before any work is carried out to the metering or valve hoses. (Risk of reflux)
Metering hoses are hoses that connect to the sample and reagent pumps. Each metering
hose must only be connected to the applicable sample or reagent pump.
Important note: Replace the sample metering hose, the discharge hose and the hose for
reagent B after 3 months. Brush the pump rollers on the sample pump with silicon paste
(Figure
Valve hoses are connections between the hose pinch valves.
Important note: Valve hoses must be replaced after 6 months.
