Condensate Discharge; Pressure Relief; Separating Buffer Tank; Circulating Pumps - Alpha-InnoTec SWC – Series Operating Manual

lw 140a/rX:
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 model.
Heat pump planning manual.
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
accessible at all times.

Pressure relief

equip the heating circuit in accordance with local
standards 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.

separating buffer tank

The hydraulic integration of the heat pump is only
permissible with a separating buffer tank (Isolation
against vapour diffusion).
The flow direction of the hot water system must also be
rotated via the switching valve during cooling.

Circulating pumps

CautIon.
always note the model.
Do not use unregulated circulating pumps.
Circulating pumps and domestic hot wa-
ter circulation pumps must be multi-
stage, regulated pumps.
