Preparations

Olives:
−
Push a hose onto the hose olive. Secure hoses against slippage with the aid of hose clips etc.
General notes:
−
Always ensure the largest possible passages in the external circuit. For a hose cross-section
that is too small
à
Temperature gradients occur between the device and external load due to
low volume flow.
−
Only operate the Integral XT when flow through the external load is possible.
−
Open any shut-off valves in the external loads.
−
Depending on the configuration of the load circuit, a venting valve can significantly simplify the
venting process. The venting valve should be positioned at the highest point of the hydraulic cir-
cuit (
þ
see the drawing on page 34).
−
Reactors for steam heating are not suitable as external loads, because they generally have an
area through which flow does not pass and in which vapor cushions can form.
−
If external control is to be used, provide a Pt100 probe in the external load.
−
Pay attention to pressure sensitive loads (e.g. glass apparatus) with a maximum
permissible operating pressure (
þ
−
Check whether the hoses for external loads have been mounted.
−
With outflow temperatures over 70 °C the supplied self-adhesive label (EZB
260) should be applied on the device at an easily visible point.
−
Do
not
carry out technical changes on the device!
+
−
The unit can be safely operated up to an ambient temperature of 40 °C.
−
An increased ambient temperature (above the reference temperature of 20 °C) re-
duces the cooling capacity and the minimum temperature that can be achieved.
−
With loads situated at a higher level and with the pump stopped and air seeping into
the thermostatic circuit (for example a not completely closed or defective venting
valve), then even with enclosed circuits, the external volume can run empty.
à
Danger that the process thermostat will overflow!
−
Install a dirt trap if the complete heat transfer system on the customer side is not
guaranteed to be dirt free.
