4 Pipe connections
General
Pipe installation must be carried out in accordance with
current norms and directives.
F2030 can only operate up to a return temperature of
about 55 °C and an outgoing temperature of about
65 °C from the heat pump.
F2030 is not equipped with external shut off valves on
the water side; these must be installed to facilitate any
future servicing. The return temperature is limited by
the return line sensor.
Water volumes
When docking with F2030 a minimum available system
volume of at least 20 litres per kW output on the heat
pump is recommended.
NOTE
The pipe work must be flushed before the heat
pump is connected, so that any contaminants
do not damage the components.
Pipe coupling heating medium
circuit
F2030 can be connected to the heating system ac-
■
cording to one of the system solutions that can be
downloaded from the website www.nibe.eu.
The heat pump must be vented by the upper connec-
■
tion (XL1) using the venting nipple on the enclosed
flexible hose.
Install the supplied particle filter before the inlet, i.e.
■
the lower connection (XL2) on F2030.
All outdoor pipes must be thermally insulated with
■
at least 19mm thick pipe insulation.
Install shutoff and drain valves so that F2030 can be
■
emptied in the event of prolonged power failures.
The supplied flexible hoses act as vibration dampers.
■
The flexible pipes are fitted so an elbow is created,
thus acting as vibration damping.
Charge pump
The temperature is controlled by the thermostat (VT
10), the charge pump is controlled directly from F2030,
terminal block (X3). If there is a risk of freezing the
charge pump will be activated by the heat pump con-
trol. Alternatively, the heat pump is connected to an
intermediate circuit consisting of a heat exchanger,
pump and water with anti-freeze. (Does not apply
when docking to NIBE indoor module.)
NOTE
If the charge pump is controlled externally it
must be operational, even if F2030 is not run-
ning, to prevent damage due to freezing.
