Condensate discharge
The outlet for the heating water safety valve and the
condensate from the air must be drained off in accord
-
ance with the respective applicable standards and reg-
ulations. Discharging the condensate and the safety
valve outlet into the sewers is only permitted via a fun-
nel waste trap, which must be accessible at all times.
►
Connect the hose for condendate discharge with
a water drain
1 Hose for condensate discharge in interior of
unit
2 Connection for the condensate discharge on
the outside of the unit
IMPORTANT
Guide the pre-mounted hose in the unit for conden-
sate discharge in the interior of the unit as a siphon,
as shown in the illustration.

1. Equip the heating circuit in accordance with local
standards and directives with a safety valve and
an expansion tank.
2.
Install filling and emptying devices, shut-off devic
-
es and non-return valves in the heating circuit.

Buffer tank
The hydraulic connection of the heat pump requires a
buffer tank in the heating circuit.
Required volume of the buffer tank:
“Technical data / scope of supply”, page 20,
“Heating circuit” section
In mono-energetic air/water systems, integrate the
buffer tank in the heating water outflow (forward flow)
before the overflow valve.
10 Circulating pumps
NOTE
Do not use regulated circulating pumps.
Circulating pumps for the heating circuit and the do-
mestic hot water circuit must be multi-stage. They
must be able to deliver at least the minimum hot water
flow rate required.
“Technical data / scope of supply“, page 20
11 Domestic hot water
preparation
Domestic hot water heating with the heat pump re-
quires an additional hot water circuit, parallel to the
heating circuit. Make sure that the heating water
charge is not channeled through the buffer tank of the
heating circuit.

12 Domestic hot water tank
If the heat pump will be used for heating hot water,
you must integrate special hot-water tanks in the heat
pump system.
►
Select the hot water tank volume in such a way
that the required amount of drinking water is avail-
able even during a utility shut-off period.
The heat exchanger surface of the hot water tank must
be dimensioned so that the heating capacity of the
heat pump is transferred with minimal spreading.
We offer a variety of hot-water tanks for you to choose
from. They are optimized for use with your heat pump.
►
Integrate the hot-water tank in the heat pump sys-
tem corresponding to the hydraulic diagram for
your system.
