4.2.2 Draining externally closed applications
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.
4.2.2.1 Draining with >Sight glass< [23]
PROCEDURE
Temperature control units without >Residues drain< [10]

Have a suitable container ready to catch the thermal fluid.

Remove the knurled screw at the
>Drain<
[8]. As soon as you have opened the knurled screw,
the thermal fluid will flow from the external application over the temperature control unit and
into the container. Check if the thermal fluid can be reused. Follow the instructions for the prop-
er disposal. → Page 15, section
»Proper disposal of resources and consumables«
.

Wait until the external application and the temperature control unit are empty.

Open the connection
>Circulation flow<
[1].

Open the connection
>Circulation return<
[2].

Leave the temperature control unit open for a while to allow it to dry out and the residue to
drain.

Close the connection
>Circulation flow<
[1].

Close the connection
>Circulation return<
[2].

Re-fit the knurled screw to the
>Drain<
[8].
The temperature control unit is now drained.
PROCEDURE
Temperature control units with >Residue drain< [10]

Have a suitable container ready to catch the thermal fluid.

Remove the knurled screw at the >Drain< [8]. As soon as you have opened the knurled screw,
the thermal fluid will flow from the external application over the temperature control unit and
into the container. Check if the thermal fluid can be reused. Follow the instructions for the prop-
er disposal. → Page 15, section »Proper disposal of resources and consumables« .

Wait until no more thermal fluid flows from the >Drain< [8].

Remove the knurled screw from the >Residues drain< [10]. The remaining thermal fluid will flow
from the temperature control unit into the container as soon as you have opened the knurled
screw. Check if the thermal fluid can be reused. Follow the instructions for the proper disposal.
