 Confirm your choice by tapping on “OK”.
 Read the Note and confirm by tapping on “OK”.
 Go to the “Home” screen.
 Tap on the keypad symbol next to “T
Setpoint
”.
 Enter a setpoint using the number keypad that appears. This setpoint must be below the low-
boiling thermofluid. The setpoint will be increased in 10 K steps during the degassing process up
to the maximum working temperature.
 Confirm your entry by tapping on “OK”.
 In the display that follows, confirm your entry again by tapping on “OK”.
The correct selection will be displayed graphically and the “setpoint” will be changed immediate-
ly. If tapping on “OK” is not correct, it will be displayed graphically for 2 seconds. The display will
return to the “Home” screen. Try changing the “setpoint” again.
 Carry out temperature control to this setpoint until the temperature in the >Expansion vessel<
[18] no longer rises or even falls.
Monitoring the temperature in the >Expansion vessel< [18].
 Go to the “Categories Menu”.
 Tap on the category “Safety”.
 Tap on the category “Display OT values”. All the measured temperatures will be displayed.
 Check the temperature in the >Expansion vessel< [18]. The degassing process is active if it in-
creases. Wait until the temperature in the >Expansion vessel< [18] no longer rises or even falls.
 Go to the “Home” screen.
 Tap on the keypad symbol next to “T
Setpoint
”.
 Increase the setpoint by 10 K.
 Confirm your entry by tapping on “OK”.
 In the display that follows, confirm your entry again by tapping on “OK”.
The correct selection will be displayed graphically and the “setpoint” will be changed immediate-
ly. If tapping on “OK” is not correct, it will be displayed graphically for 2 seconds. Then the dis-
play will return to the “Home” screen again. Try changing the “setpoint” again.
 Carry out temperature control until the temperature in the >Expansion vessel< [18] no longer
rises or even falls.
 Check the temperature in the >Expansion vessel< [18] again.
 Continue to increase the setpoint by 10 K increments until the temperature in the >Expansion
vessel< [18] no longer rises during an increase.
 Now maintain the thermal fluid at the last temperature set until the >Expansion vessel< [18] has
reached ambient temperature.
The entire process can take several hours, depending on the degree of contamination and the
application size. Continue the control process until the temperature in the >Expansion vessel< [18]
has returned to ambient temperature.
 Go to the “Categories Menu”.
 Tap on the category “Temperature Control”.
 Tap on the category “Start/Stop”.
 Tap on the dialog entry “Stop degassing”.
 Confirm your choice by tapping on “OK”.
 Read the note and confirm by tapping on “OK”. Degassing stops immediately and the pump
continues to run for approx. 30 seconds. Wait until the pump stops.
 Connect a suitable drain hose (must be compatible with the thermofluid) to the >Expansion
vessel drain< [9] (if fitted) or >Drain< [8] an.
 Place the other end of the hose in a suitable container, which is compatible with the thermofluid
and the thermofluid temperature.
 Drain the >Expansion vessel< [18]. To do so, open the >Expansion vessel drain valve< [5] by
turning it counterclockwise (turn 90° left as far as it will go). Pay attention to the high tempera-
ture of the thermofluid. On page 16 observe section »Proper disposal of resources and consum-
ables«.
 Close the >Expansion vessel drain valve< [5] by turning it clockwise (turn 90° right as far as it will
go).
 Remove the drain hose and the container.
 Open the >Expansion vessel cap< [22] by hand.
 Carefully pour original thermofluid into the >Filling port< [17], using the filling accessories (fun-
nel and/or beaker). The fill levels are displayed in the >Sight glass< [23] or >Level indica-
tor/Level< [25]. Do not mix different thermofluids.
 Close the >Expansion vessel cap< [22] by hand.
 The de-gassing process is complete.
