SERIOUS BURNS/FREEZING OF THE HOUSING PARTS/ESCAPING THERMAL FLUID

Do not move temperature control units that are in operation.
4.1.1 Turning on the temperature control unit
PROCEDURE

The temperature control unit must be filled with thermal fluid before you turn it on via the
>Mains switch< [37] (see on page 37 Section »Filling, venting, degassing and draining« ). An er-
ror message appears on the display after a short time if the temperature control unit is switched
on without thermal fluid. If this is the case, switch off the temperature control unit using the
>Mains switch< [37] and fill it.

Switch on the temperature control unit using the >Mains switch< [37]. The float switch monitors
the thermal fluid level. The float switch is automatically pressed down. The buoyancy of the float
forces it upwards when thermal fluid is filled and thus the test is passed. The test may generate
some sounds.
Circulation and thermoregulation are turned off.
4.1.2 Turning off the temperature control unit
PROCEDURE

Warm the thermofluid to room temperature.

Stop the thermoregulation.

Switch off the temperature control unit using the >Mains switch< [37].
4.1.3 Setting the overtemperature (OT) protection
The overtemperature protection is set higher than the ignition temperature of the thermal fluid
used
MORTAL DANGER FROM FIRE

The overtemperature protection must be correctly set to the thermal fluid you are using.

Always observe the safety data sheet of the thermal fluid.

Set the cut-out value of the overtemperature protection at least 25 K below the fire point of
the thermal fluid.
4.1.3.1 General information on the overtemperature protection
The overtemperature protection is installed only in temperature control units that have a heater.
The flow temperature is monitored to ensure the safety of your system. It is set immediately after
you have filled the system with thermal fluid.
Upon delivery, the cut- out value of the overtemperature protection is set to 40 °C. An alarm is trig-
gered by the temperature control unit shortly after turning on the power if the temperature of the
