With devices up to 300 °C operating temperature range (H devices) switchover occurs alter-
nately every 20 seconds between the individual hydraulic paths. When this happens, a long
whirring sound is heard for about 5 seconds and the displayed pressure changes.
−
Terminate the filling mode with the soft key Stop .
−
A venting valve (
þ
see drawing on page 34 for arrangement) can significantly simplify the
venting process. To do this, carefully open the valve periodically and allow air to escape until
liquid is emitted from the valve, close the valve again. Collect the liquid in a suitable container.
Open the valve again at regular intervals until no more air is emitted.
7.6.3
Degassing
Command
Degassing (expelling low-boiling solvents):
−
Principle: During degassing the heat
transfer liquid is in the boiling state. The
gas can arise at various points in the cir-
cuit (e.g. heater, throttle point).
−
A gravity separator, through which the
gas is passed into the expansion tank, is
positioned in front of the pump.
7.6.3.1 Automatic degassing program
After filling and venting, the heat transfer liquid should be heated up to 20°K above the later maximum
operating temperature (note the maximum temperature range of the heat transfer liquid (
þ
6.2)), note
the maximum working temperature range of the connected consumer).
−
The degassing program should be carried
out to automate this first-time degassing:
−
Enter the maximum temperature up to
which degassing is to take place. To do
this, press the key "Enter", enter the new
set value and confirm it.
