Nibe F370 Installer Manual

Preparations
1.
Check that the switch (SF1) is in position " ".
2.
Check that the filling valves (QM10) and (QM11)
are fully closed.
Caution
Check the miniature circuit-breaker (FA1) in
the heat pump. It may have tripped during
transportation.

Filling the hot water heater
1.
Open a hot water tap in the house.
2.
Open the filling valve (QM10). This valve should
then be fully open during operations.
3.
When water comes out of the hot water tap, the
hot water heater is full and the tap can be closed.
Filling the climate system
1.
Check that the shut off valves for the heating sys-
tem (QM31) and (QM32) are open.
2.
Open the venting valve (QM20).
3.
For F370, stainless steel: Check if the flexi hose
supplied is connected between connection (QM11)
and connection (QM13). Adjust the hose if this has
not been done.
4.
For F370, copper or enamel: Open the filling valve
(QM11). The boiler section and the rest of the cli-
mate system are filled with water.
For F370, stainless steel: Open the filler valves
(QM11), (QM13). The boiler unit and the rest of
the climate system are filled with water.
5.
When the water that exits the vent valve (QM20)
is not mixed with air, close the valve. After a while
the pressure rises on the pressure gauge (BP5).
When the pressure reaches 2.5 bar (0.25 MPa) the
safety valve (FL2) starts to release water. Close the
filler valve(s) (QM11) and (QM13).
6.
Reduce the boiler pressure to the normal working
range (approx. 1 bar) by opening the vent valve
(QM20) or safety valve (FL2).
7.
Check that there is water in the overflow cup
(WM1).
If the overflow cup requires topping up:
1.
Turn the safety valve (FL1) anticlockwise carefully.
Venting the climate system
1.
Turn off the power supply to the heat pump.
2.
Vent the heat pump via the vent valve (QM20) and
the rest of the climate system via the relevant vent
valves.
3.
Keep topping up and venting until all air has been
removed and the pressure is correct.
NOTE
The vent pipe from the container must be
drained of water before air can be released.
This means that the system is not necessarily
bled despite the flow of water when the bleed
valve (QM20) is opened.
