6 Install electric heating element
Wilo-Stratos PARA (K 12, K 15)
–
The flow sensor 1 must be installed upstream of
the circulation pump when viewed in the direction
of flow.
–
The calming section 2 before and after the flow
sensor must not be removed.

trically

Connect the flow sensor electrically > 35
7.4 Connect the primary circuit
There are two fundamental options for connecting the
primary circuit to the heat pump:
–
Inlet from the heat pump bottom , (from the con-
crete foundation) with the connection set bottom >
24
–
Inlet from the heat pump rear , with the connection
set rear > 25
Both solutions are described in detail below.
Important installation information for connecting
the primary circuit
–
The connecting cable from the connection on
the heat pump to the building must be a fle-
xible connection. This is ensured by using
the SOLARFOCUS connection set.
–
The line routing must always provide a bend.
Avoid direct and straight line routing. Avoid
line routing under tension or pressure.
–
Avoid hose lengths smaller than 30 cm.
–
If these specifications are not adhered to,
there is a risk that vibrations and thus, noise
will be transmitted in the living space.
!
CAUTION - Due to the oscillating bearing of
the heat pump unit, the hydraulic connection
to the heating system must not be carried out
as a rigid connection.
!
CAUTION - The connection to the heating sys-
tem must not be carried out with stainless
steel corrugated pipes (material not suitable).

7.4.2 Cut insulating mat (only required for K
08 and K 10)
►
To introduce the primary circuit lines, cut the
soundproofing insulation (mat). After installation
of the pipes, pay attention to the best possible
sealing.

7.4.3 Primary circuit connection set
The SOLARFOCUS connection sets are supplied
from the factory suitable for direct connection to the
condenser (plate heat exchanger).
i
When using the optional electric heating
element, the flow line on the connection sets
must be shortened on site (the flow connec-
tion is located lower in the case of the electric
heating element than in the plate heat exchan-
ger).
