9 The vacuum leak sealing bag must only be used with tested,
original Vetter fittings.
9 The following information only relates to application of com-
pressed air coming from the compressed air bottle 200 bar or
300 bar.
9 The backpressure of the pressure regulator must be set to at
least 2 bar.
9 Observe the indication on the manometer.
9 Join the connection hose of the pressure regulator to the va-
cuum jet, if necessary extend it with the air supply hose (10 m,
green, accessory).
9 Press the plug-in nipple into the coupling until you feel it lock
in.
9 Insert and lock the vacuum nozzle with ventilation hose to the
vacuum connection of the bag.
9 Couple the stainless steel ball valve with the outlet hose to the
vacuum leak draining bag and open the ball valve.
9 Prepare the collection container.
9 Open the blocking valve of the pressure regulator and the va-
cuum connection until the air can be heard to flow through.
9 Press the vacuum leak draining bag onto the container wall
so that the drainage chamber is centred over the leak position
(observe the drain chamber size of 200 mm).
9 The complete outside rubber lip of the bag must be positi-
oned on the container wall.
9 With curved containers, the vacuum leak draining bag must
also be pressed using four hands.
9 Continually observe the under-pressure manometer and the
vacuum leak draining bag. Do not interrupt the air flow.
9 The liquid is diverted into a collection container via the ball
valve.
9 The ventilation hose of the vacuum jet must also terminate
in a container in order to reliably drain any liquid remaining
within the vacuum chamber.
