Functional description
The Multidis SF heating circuit distributor/ collector serves the distribution of the medium to the corresponding surface heating/ cooling circuits. The valve inserts in the return collector have an M30 x 1.5 connection thread. The valve inserts can be equipped with a thermostatic head or actuator for individual room temperature control.

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.

Install a ball valve in front of the flow distributor/return collector for the isolation of the supply and return pipe.

Operating elements and displays
The flow rate is set and regulated with the help of the regulating inserts.

1. Adjustment screw
2. 6 mm hexagon socket
3. 5 mm hexagon socket
4. Valve spindle
5. Valve open
6. Valve closed

Technical description

Set the flow rate as follows:
Carry out setting whilst the circulation pump is in operation.

1. Close the valve spindle with a 5 mm hexagonal spanner.

2. Open the valve spindle (see Fig. 3 on page 20 (4)) by turning it anticlockwise according to the calculated preset value.
   (Example: Presetting 2.5 = 2.5 turns)

3. Turn the adjusting screw against the valve spindle as far as it will go using a 6 mm hexagonal spanner.
   The last set value can be restored using the adjustment screw if, for example, the heating/cooling circuit is shut off by the valve spindle at a later time.

4. Perform this procedure for all heating and cooling circuits.

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.

Commissioning

Filling, bleeding and leak testing of the installation

1. Open the ball valves.
2. Fill the system via the risers up to the Multidis SF heating circuit distributor/ collector.
3. Close the ball valves.
4. Flush and fill the individual heating/cooling circuits via the fill and drain cock at end of the flow distributor up to the fill and drain cock at the end of the return collector. Flush and fill each surface heating/cooling circuit separately. The G ¾ connection of the fill and drain cock is suitable for the connection of a standard DN 15 hose fitting.

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 “Co floor Surface heating and cooling systems/Systems with distributor/collector”.

Hydronic balancing
Carry out hydronic balancing by use of integrated regulating inserts.

Correction factors for water-glycol mixtures
Take the correction factors of the manufacturers of the antifreeze liquids into consideration when setting the flow rate.

Maintenance

Regularly check the tightness and function of the product and its connection points as part of system maintenance.
