LW 140… THROUGH LW 310…
AND LW 320H…:
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…
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.
