Operation

The leakage test and test pressure
have to be recorded. The leakage
test record is available as sample
form on our homepage.
f Visit www.oventrop.com.
f Select the menu point
"Products".
f Proceed to "Brochures".
f Select "Surface heating and
cooling Cofloor".
f The leakage test record can
be found in the brochure
"Cofloor Surface heating and
cooling systems - System with
distributor/collector".

7.2 Regulation

The risers of the heating/cooling system have
to be hydraulically balanced. Regulation of the
surface heating/cooling circuits is carried out at
the stainless steel distributor/collector "Multidis
SF".
8. Operation
NOTICE
Damage to the screed from
wrong temperatures!
f Carry out incremental heating of
concrete and calcium sulphate
screed according to DIN EN 1264-
4.
f The instructions of the screed
manufacturer have to be observed.
f The flow temperature must be co-
ordinated with the surface heating/
cooling system.
Near the heating pipes, the maximum
permissible screed temperatures
according to DIN must not be
exceeded. In surface cooling systems,
the temperature near the cooling pipes
must not reach the dew point.

8.1 Incremental heating test

The function of the heated floor construction is
tested during the incremental heating test.
Start the incremental heating test at the
earliest:
• 21 days after laying of concrete screed
• 7 days after laying of calcium sulphate
screed
Proceed as follows:
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.
The flow temperature is controlled via the heat
generator control.
The incremental heating test has to
be recorded. The incremental heating
test records are available as sample
form on our homepage.
f Visit www.oventrop.com.
f Select the menu point
"Products".
f Proceed to "Brochures".
f Select "Surface heating and
cooling Cofloor".
f The incremental heating test
records can be found in the
brochure "Cofloor Surface
heating and cooling systems
- Systems with distributor/
collector".

8.2 Hydronic balancing

Hydronic balancing is carried out using the
integrated flow measuring and regulating
devices.
