Flexible squeeze valve
The machine has an internal flexible squeeze valve for the rinse
process. This valve switches over between the drain and the
weighing systems. Generally, the flexible squeeze valve is maintenance free.
The possibly required maintenance intervals for this flexible
squeeze valve strongly depend on how abrasive your sample is.
Change the hose if you notice any leakages. You must remove
the entire hood for this purpose.
Connect the replacement hose to the intake of the squeeze valve. The hose system must be fitted exactly as it was before.
Therefore, note the exact position of the new hoses before removing the old ones. Wrongly connected hoses could cause the
machine to malfunction.
"Drain“ hose: rear connection of the squeeze valve
"Weighing system" hose: front connection of the squeeze valve.
Caution!!!
The hose is a special accessory. Replace it only with an original
hose.
Depending on the condition of the substances measured, the
tightness of the silicone hoses should be checked regularly.
