CAUTION!
Risk of external consuming unit bursting
Scalding, cold burns

If the external consuming unit is located in a lower position
and is sensitive to pressure, also take into account the
additional pressure resulting from the difference in height
between the consuming unit and the device.
Please note:
n
Only connect hydraulically closed applications to the device!
n
Use the shortest possible hoses with the largest possible diameter in the
external circuit.
If the diameter of the hose is too small, there will be a temperature
gradient between the device and the external application due to the low
flow rate. In this case, increase the outflow temperature or pump level
accordingly.
n
Secure the hoses to the hose nozzles using hose clips.
n
If using a pressure-sensitive application (such as a glass reactor), use a
pressure relief device.
n
Open any shut-off valves in the external application. Only switch on the
device when flow is possible through the external application.
n
Depending on the type of application, a vent valve can significantly
simplify the aeration process. The vent valve must be located at the
highest point of the circuit (Fig. 12).
n
Reactors for steam heating are not suitable as external applications, as
they usually have a non-flow-through area in which gas cushions can
form.
n
If external control is used, a Pt100 sensor must be installed in the
external application or the external temperature signal is transmitted via
an interface module.
n
If the external application is in a higher position, the application may run
empty if the pump is switched off and air enters the thermostatic circuit
(e.g. due to an incompletely closed or defective vent valve). This can
cause the heat transfer liquid in the process thermostat to overflow.
n
Install a dirt trap if the circuit in the application is not free of dirt.
