[Dsg-mvt] Mixing system

[mdefurne]

Hi Marc,

Thank you for the update. Before inserting the MVT in the solenoid, we 
will have to check that everything has been plugged back properly. To do 
so, we will need gas.

A back-up plan will be to have the gas line ready and plug a premix 
bottle on it. What is the procedure to follow to have this back up plan 
ready for the MVT installation in the Hall? Unfortunately it is 
necessary to prepare this back-up plan because we won t insert the CVT 
in the solenoid without checking that everything is OK.

Kind Regards,

Maxime
