Functional description

The Multidis SFQ heating circuit distributor/ collector serves the distribution of the medium to the corresponding surface heating/ cooling circuits.
The Multidis SFQ heating circuit distributor/ collector is equipped with the QM valve insert.  The QM valve insert enables automatic flowcontrol (hydronic balancing) of the surface heating and cooling systems, as the valve insert is infinitely presettable, diaphragmcontrolled and differential pressureindependent.The differential pressure is kept constant over the presetting and control cross-section of the valve by the flow control unit integrated in the valve insert. Printed stickers are included with the heating circuit distributor/collector to identify the individual circuits.You can attach these to the heating circuit distributor/collector. The heating/cooling circuits can be filled, flushed and bled via the fill and drain cocks

Operating elements and displays

Set the flow rate using the presetting key directly on the handwheel of the QM valve insert (the set values can be read directly from the outside).This protects against manipulation of the preset value by unauthorised persons.The valve insert is infinitely adjustable. A correction of the set value is also possible while the system is running.

•  The flow indicators in the flow distributor must be in the fully open position (factory setting).They do not serve to set the flow rates!
•  The position of the indicator ring in the sight glass has no direct relation to the flow rate set on the QM valve insert

Install ball valves in front of the flow distributor/return collector to shut off the supply and return pipe.

Installation

NOTICE

Damage to property due to lubricants!

Seals can be destroyed by the use of greases or oils.

• Do not use greases or oils during installation.
• If necessary, flush dirt particles and grease and oil residues out of the  pipework.
• When selecting the operating medium, observe the general state of the art (e.g. VDI 2035).
• If the operating medium is contaminated, install a strainer in the supply pipe (VDI 2035).

The brackets enable mounting on the wall or in the cabinet.

1. Mount the flow distributor (at the top) and the return collector (at the bottom) into the sound-absorbing brackets.
2. Mount them onto the wall or in the cabinet.

The supply and return pipe can be connected from either the left or right hand side.

Commissioning

Filling, bleeding and leak testing of the installation

Before commissioning, you have to fill and bleed the installation.

1. Close the ball valves in front of the flow distributor and the return collector.
2. Fully open the QM valve inserts.
3. Set the handwheel with the presetting key to the set value 5.The G ¾ connection of the fill and drain cock is suitable for the connection of a commercially available DN 15 hose fitting.
4. Apart from the circuit to be filled, close all valve inserts QM using the protection cap.
5. Flush and fill each circuit one after the other via the fill and drain cock at the return collector to the fill and drain cock at the flow distributor.
6. Carry out a leak test according to DIN EN 1264.

Record the tightness and the test pressure in a test record.You can find the test record as a copy template on our website.

• Visit www.oventrop.com
• There, select the menu option DOWNLOADS & SOFTWARE.
• Proceed to BROCHURES.
• Select SURFACE HEATING AND COOLING COFLOOR.
• You can find the test record in our brochure “Cofloor Surface heating and cooling systems/Systems with distributor/collector”.

Protection cap

The Multidis SFQ heating circuit distributor/ collector is supplied with a protection cap (see Fig. 2 on page 19) made of plastic on the QM valve insert. On the one hand, it protects the valve spindle, and on the other hand, it can be used to manually adjust the valve stroke during the construction phase.

• Turning clockwise
• The valve insert closes and the heat supply is reduced
• Turning anticlockwise
• The valve insert opens and the heat supply is increased

Operation

NOTICE

Damage to the screed due to wrong temperatures!

Do not exceed the maximum permissible screed temperatures according to DIN near the heating pipes. In surface cooling systems, the temperature near the cooling pipes must not reach the dew point

• Carry out incremental heating of concrete and calcium sulphate screed according to DIN EN 1264-4.
• Follow the manufacturer’s specifications for all screed materials.
• Match the flow temperature to the heating or cooling system.

Incremental heating

Check the function of the heated floor construction during incremental heating. Start incremental heating at the earliest:

• 21 days after laying of concrete screed
• 7 days after laying of calcium sulphate screed

Proceed as follows during incremental heating

1. Open all valve inserts at the return collector with the help of the protection cap.
2. Heat up with a flow temperature between 20 °C and 25 °C for at least 3 days.
3. Heat up with the maximum design flow temperature for at least 4 days.

Set the flow temperature via the heat generator control.

Record incremental heating in a test record. You can find the test record as a copy template on our website.

• Visit www.oventrop.com.
• There, select the menu option DOWNLOADS & SOFTWARE.
• Proceed to BROCHURES.
• Select SURFACE HEATING AND COOLING COFLOOR.
• You can find the test record in our brochure “Cofloor Surface heating and cooling systems/Systems with distributor/collector”

Correction factors for water-glycol mixtures
