8 Installation and commissioning
!
WARNING
Hot water!
Severe scalding possible.
• Allow the product to cool before carrying out any maintenance,
cleaning or work repair.
• Do not put hands into hot water when draining the product.
8.1 Pipe installation
1. Cut the plastic, copper or multilayer pipe to length perpendic-
ular and deburr / calibrate. Push the clamping ring nut over
the pipe.
2. Push the grab ring onto the pipe and insert the hose nozzle.
3. Push the conical end of the pipe all the way into the connec-
tion on the manifold.
4. Tighten the clamping ring nut by hand. Push the plastic, cop-
per or multilayer pipe up to the stop.
5. Hold the outlet screw connection using a 24 mm open-end
wrench or spanner and tighten the clamping ring nut using a
30 mm open-end spanner (approx. 25-30 Nm). Fit the pipe
without any tensile, compressive or torsional forces.
Do not exceed the max. torque stated in the installation in-
structions for the compression joint used.
8.2 Shutting off the heating circuit
1. The valves on the return can be closed, e.g. for flushing and
filling the heating circuit. To do this, put the protective cap on
the valve and close it by turning it clockwise.
2. The flow meter can be closed with a air vent key. However,
this is not necessary for filling and flushing the circuits.
If the flow meter is shut off, the following opening sequence
must be observed in order to avoid malfunction or damage.
First, open the flow meter, then the control valve.

8.3 Flushing and filling the circuits
!
CAUTION
Material damage!
Opening shut-off valves quickly produces pressure surges.
• Always open shut-off valves slowly and in a controlled manner.
üAll flow meters must be completely open.
üThe system pressure must not exceed 3 bar when flushing
and filling.
1. Close ball valves 1 and 2 on the manifold.
2. Close all valves on the return using the protective caps.
3. Attach the flushing and filling hose to the fill and drain valve 3
on the supply side; the discharge outlet on fill and drain valve
4 must be open.
4. Completely open the valve on the circuit to be flushed using
the protective cap.
5. Flush the circuit with clear water.
6. Once flushing is over, close the control valve and flush/fill the
next circuit.
7. Once the flushing and filling procedures are complete, remove
the hose from the end set (fill and drain valves 3 and 4).
8. When venting using the end set Q1 and KFE90, follow illustra-
tions A and B on this page.
9. The protective end caps are to be fully closed off once the
system has been flushed and filled.
