When changing from low-boiling thermal fluid (low-boiling components) to higher boiling thermal
fluids, remains of the low-boiling component may remain in the temperature control unit. Depend-
ing on the working temperature, the low-boiling component begins to boil and gas bubbles are
formed that cause the pump pressure to momentarily collapse. This may cause a safety shutdown.
The gas bubbles reach the bath opening and can escape.
If ice crystals form on the evaporator coil, water has accumulated in the thermal fluid. Degas if this
is the case, to avoid damage to the temperature control unit.
Thermal fluids are more or less hygroscopic (water-attracting). This effect increases, the lower the
working temperature. The de-gassing mode below, which must be
permanently monitored
, also
helps you remove any water residues from the temperature control circuit.
PROCEDURE
Follow venting with the degassing operation. Prerequisite: You have filled the temperature con-
trol unit in accordance with the instructions on page 55 in Section
thermostat and the externally closed application«
and/or cleaned it as per page 66 in Section
»Rinsing the thermal fluid circuit«
.
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 lower
boiling thermal fluid. This 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 immediately.
If tapping on “OK” is not correct, it will be displayed graphically for 2 seconds. The display will re-
turn to the “Home” screen. Try changing the setpoint again.
Tap on the “Start” touch button.
Confirm the start of temperature control by tapping on “OK”.
The correct selection will be displayed graphically and temperature control will start 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 starting the thermoregulation again.
Carry out temperature control to the entered setpoint until no more gas bubbles rise up.
Increase the setpoint by 10 K and carry out temperature control until no more gas bubbles rise
up.
Repeat increasing the setpoint by 10 K until the maximum working temperature of the thermal
fluid has been reached.
Tap on the “Stop” touch button as soon as no more gas bubbles rise up at the thermal fluid’s
maximum working temperature.
Confirm the stop of the temperature control process by tapping on “OK”.
The correct selection will be displayed graphically. Thermoregulation is stopped immediately and
the pump continues to run for approx. 30 seconds. Wait until the pump stops. If tapping on “OK”
is not correct, it will be displayed graphically for 2 seconds. The display will return to the “Home”
screen. Try stopping the temperature control process again. The de-gassing process is complete.

Draining the bath thermostat
Hot or very cold thermal fluid
SEVERE BURNS/FROSTBITE OF LIMBS
Before draining, ensure that the thermal fluid has room temperature (20 °C).
If, at this temperature, the thermal fluid is too viscous to be drained: Control the temperature
of the thermal fluid for a few minutes until the viscosity will allow drainage. Never control the
temperature of the thermal fluid when the Drain is open.
Danger of burns when draining thermal fluids at temperatures above 20
°C.
Wear your Personal Protective Equipment for draining.
Only drain using suitable drainage hose and collecting container. These must be compatible
with the thermal fluid and its temperature.
