
Check the level in the collecting container. Empty the container when necessary and dispose of
its contents properly.

In case of overfilling, drain thermal fluid via the >Drain< [8] into a suitable container (see page 38
the section
»Draining the bath thermostat«
. Check if the thermal fluid can be reused. Please
note on page 15 the section
»Proper disposal of resources and consumables«
.
4.2.1.2 Degassing of bath thermostat
Hot or cold thermal fluid and surfaces
BURNS TO LIMBS

Avoid direct contact with the thermal fluids or the surfaces.

Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).
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 37 in Section »Filling and venting the bath
thermostat and the externally closed application« and/or cleaned it as per page 51 in Section
»Rinsing the thermal fluid circuit« .

Enter a setpoint as described on page 34 in Section »Setting the setpoint« . This setpoint must be
below the lower boiling thermal fluid. This setpoint will be increased in 10 K steps during the de-
gassing process up to the maximum working temperature.

Start the temperature control process as described on page 40 in Section »Starting the tempera-
ture control process« .

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.

Stop the temperature control process as described on page 40 in Section »Ending the tempera-
ture control process« .

The de-gassing process is complete.
4.2.1.3 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.
