Pressure relief
equip the heating circuit in accordance with local stand-
ards and directives with a safety valve and an expansion
tank.
Also install filling and emptying devices, shut-off devices
and non-return valves in the heating circuit.
Overflow valve
Use an overflow valve for tanks integrated in series to
ensure the minimum flow rate of the heating circuit vol-
ume flow through the heat pump. The overflow valve
must be dimensioned so that the minimum flow rate of
the volume flow through the heat pump is ensured when
the heating circuit is shut off.
Buffer tank
The hydraulic connection of the heat pump requires a
buffer tank in the heating circuit. It ensures a minimum
operating time of the heat pump when the heating cir-
cuit valves are closed. The required volume of the buffer
tank is calculated based on the following formula:
v
buffer tank
=
minimum flow rate of heat circuit volume flow / hour
10
for the minimum flow rate of the heat cir-
cuit volume flow, see overview “Technical
data / Scope of delivery”, “Heating circuit” sec-
tion.
In mono-energetic air/water systems, integrate the
buffer tank in the heating water outflow (forward flow)
before the overflow valve.
Condensate disCharge
The condensation water that accumulated from the air
must be drained via the pre-mounted hose in the unit
for condensate discharge. To do so, connect the hose
for condendate discharge with a water drain.
for positioning of the connection for conden-
sate discharge, see dimensional drawings for the
respective model.

guide the pre-mounted hose in the unit
for condensate discharge in the interior of
the unit as a siphon, as shown in the illus-
tration.
discharge of the condensate into the sewage system is
permitted only via a funnel siphon, which must be acces-
sible at all times.
