Cooling circuit connections

Scope of supply
The unassembled connecting hose is supplied with the loose parts so that it can be adapted
to the local conditions.
Six hose connections (straight and angled) with the associated gaskets are also supplied.
Enough connection hose is supplied so that the filter reactor and the filter module can be
installed as shown in Section "Notes on installation in a control cabinet (Page 59)".
Connection diagram
The cooling circuit connections can be taken from the connection example.
Establishing the connections
If the components and the cooling water feed are arranged as described above, then the
supplied unassembled pressure hose can be used.
If a different arrangement is used, connecting hoses of the same quality must be used:
● Hose diameter 3/4"
● Pressure rating, minimum 12 bar
● Maximum hose length 2 m
● Non-conductive, resistance 1 MΩ/m
The hose connections must be fastened with the gaskets with a tightening torque of 30 Nm:
● The straight hose connection is intended for P1.
● The angled hose connections are intended for P4, P6 and P7.
The hoses must be fastened to the hose connections with two hose clamps each with a
tightening torque of 3 Nm.
After assembly, the tightness must be tested with a pressure test.
