key. TSHE is calibrated together with TSE.
The components of the degassing and heating circuit can be tested step by

All balance chamber valves are switched so that one half of the balance
chamber is open and the other side closed to position the membrane.
The flow pump FPE and FPA have the same speed and work in main flow. If the
speed of FPE is set the degassing pump EP starts automatically with a higher
speed.
The heater H is stopped if the degassing pump EP < 500 rpm, the degassing
temperature sensor TSE > 89
o
C or the upline tank VB is empty.
The degassing pump EP must be able to build up a flow of > 1200 ml/min at a
negative pressure of - 500 mmHg.
