As reported in the entry 32936, an inspection of the IB smalltrap valve was necessary. In order to allow VAC team to access the valve from the inside of the INJ tower, and so not to dismantle the whole valve, we temporarily removed the baffles at the output flange of the tower (see first picture). After Antonio tightened a bit more the screws holding the in-valve embedded viewport, we proceeded to re-install the baffles that are now correctly in place (second picture).
