Screw 1, 2, 3 or 4 tensio shafts into the
adapters.
Put blind plugs on connections not used.
Fill beaker(s) with deionized water.
Close valve of the beaker unit.
Set timer according to a rhythm of
e.g. 5 min "on" and 55 min "off".
Note
If the manometer of the vacuum mount drops rapidly the system is leaking. Please check,
fix leakage and restart degassing procedure. If you use another pump than the HYPROP
pump, make sure that it is able to provide a vacuum value that is 8 hPa (0.8 kPa) below
atmospheric air pressure. The power does not matter! Vacuum pumps that reach only a
smaller vacuum value are not suitable.
Timer starts the pump automatically and
works in the rhythm set. The water in the
tensio shafts is degassed after minimum 24
h running time.
