When cold, the water volume of the expansion tank
amounts to 0.6 l (corresponds to 20 % of the tank

The values indicated in the table are approximate
values. In particular cases, significant deviations are
possible.
NOTICE
When used in an underfloor heating system, it is
recommended to replace the temperature
controller with a lower control range temperature
controller (OV item no. 1142861, control range
20- 50 °C).
With a heat demand of approx. 13 kW in the heating
circuit of the dwelling, the floor area should be limited
to 100 m² (calculation based on a laying distance of
150 mm).
Fluid: Non-aggressive fluids (e.g. water and suitable
water and glycol mixtures according to VDI 2035). Not
suitable for steam, oily and aggressive fluids.
DANGER
Suitable measures (e.g. safety valves) have to be
taken to ensure that the maximum operating
pressures and maximum and minimum operating
temperatures are not exceeded or undercut.
If necessary, provide an electric sensor attached
to the pipe (safety temperature limiter OV item
no. 1143000) to protect the surface heating
circuit from unacceptably high temperatures.
NOTICE
The operating instructions of the pump
manufacturer must be observed
