Nibe F2050-10 - Installation Alternative

Before installing the heat pump in an existing system, it is
important that the system is properly flushed through.
Even if the heat pump is to be installed in a new system, the
heat pump and system should be flushed.
NOTE
Ensure that cleaning agent has been removed from
the entire system before adding inhibitor.
After flushing an inhibitor should be used for long-term anti-
corrosion protection.
NIBE Energy Systems Limited recommends water treatments
(supplied by e.g. Fernox and Sentinel) specifically designed
for heat pumps.
CHARGE PUMP
The charge pump (not included in the product) is powered
and controlled from the indoor module/control module. It
has a built-in frost protection function and, for this reason,
must not be switched off when there is a risk of freezing.
At temperatures below +2 °C the charge pump runs period-
ically, to prevent the water from freezing in the charge cir-
cuit. The function also protects against excess temperatures
in the charge circuit.

PIPE CONNECTIONS FLEX HOSE
All outdoor pipes must be insulated with at least 19 mm thick
pipe insulation.
The supplied flexible hoses act as vibration dampers. The
flexible pipes are fitted so an elbow is created, thus acting
as vibration damping.
