Vent Internal Tube Issue

[Bob_The_Reefer]

Is it normal that when venting the internal reagent tube the dosing line parts at the connection to the rubber pump head tube?

Hello,

Are you saying the reagent tube is detaching from the pump head when running the "vent internal reagent tube" function?
If yes, then this can happen if the reagent tube was not fully primed before connecting it to the KHD reagent IN connector.

Yes but the tube is fully primed

I'm new to the GHL equipement. MY new KHD + SA doser 2.1 is running for 4 days.

I had the same problem : Is it normal that when venting the internal reagent tube the dosing line parts at the connection to the rubber pump head tube?

The line was fully primed, but it was just after i connected it to the KHD reagent in.
