make sure that frost-free condensate discharge is
ensured…
Installation plan for respective unit model.
Seal empty pipes on unit side.
Condensate disCharge
The condensate from the air must be discharged frost-
free via a condensate pipe with a minimum diameter of
50 mm. for underlying surfaces that are permeable to
water, it is sufficient to insert the condensate pipe ver-
tically at least 90 cm into the ground. If the condensate
is discharged into drainage or sewage systems, install
frost-free with gradient.
discharge of the condensate into the sewage system is
permitted only via a funnel siphon, which must be acces-
sible at all times.
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.
Rinse heating circuit thoroughly prior to connecting
the unit to the heating circuit…
notICe:
contamination and deposits in the heating cir-
cuit can cause malfunctions.
Install shut-off devices for the hot water outflow
(forward flow) and hot water inflow (return flow)
on the heat pump side…
notICe:
during installation of the shut-off devices, the
evaporator and liquefier of the heat pump can be
rinsed, if necessary.
CautIon!
the condenser may be rinsed only by cus-
tomer service personnel authorized by
the manufacturer.
connect the unit to the pipes of the heating cir-
cuit via vibration decouplers. They must be installed
in order to prevent damage from vibrations to the
pipes.
notICe:
vibration decouplers are available as accesso-
ries.
1 hot water inflow (return flow) connection
2 hot water outflow (forward flow) connection
3 condensate water hose
Install the condensate water hose in the unit so that
there is no contact with refrigerant pipes…
