6 Installation of hydraulic system
1. Install the outside pipes of the heating circuit be-
neath the frost line.
NOTE
If an existing system is being replaced, the
old vibration decoupling may not be reused.
2. Flush the heating circuit thoroughly before con-
necting it to the heating system.
IMPORTANT
Damage to the copper pipes due to impermissible load!
►
Secure all connections against twisting.
Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned.
The free pressing of the circulation pumps pro-
duces at least the minimum throughput required for
the model (
“Technical data / scope of supply”,
page 17).
The hydraulic system must be equipped with a
buffer tank, the required volume of which depends
on your model.
“Technical data / scope of supply”, page 17
The lines for the heating are fastened to the wall or
ceiling via a fixed point.
1 Heating water supply
2 Condensate fitting
3 Heating water return
3. Insert the vent at the highest point of the heating
circuit.
4. Ensure that the operating overpressures (
“Tech-
nical data / scope of supply”, page 17) are
complied with.
Condensate connection
The heating water drained from the safety valve and
the condensate that accumulates from the air must be
discharged in compliance with the applicable stand-
ards and regulations. Discharge of the condensate
and of the water drained from the safety valve into the
sewage system is permitted only via a funnel waste
trap, which must be accessible at all times.
