Nibe S1155PC, Руководство по установке, Страница: 27 / 80

Preparations
1. Check that the externally mounted filling valves are fully
closed.
Caution
Check the miniature circuit-breaker (FC1). It could
have tripped during transport.
NOTE
Do not start S1155PC if there is a risk that the wa-
ter in the system has frozen.
Filling and venting
Caution
Insufficient venting can damage internal compon-
ents in S1155PC.
FILLING AND VENTING THE CLIMATE SYSTEM
Filling
1. Open the filling valve (external, not included in the
product). Fill the climate system with water.
2. Open the vent valve .
3. When the water that exits the vent valve is not mixed
with air, close the valve. After a while, the pressure
starts to rise.
4. Close the filling valve when the correct pressure is ob-
tained.
Venting
1. Bleed the heat pump via a vent valve and the rest of the
climate system via their relevant vent valves.
2. Keep topping up and venting until all air has been re-
moved and the pressure is correct.
FILLING AND VENTING THE BRINE SYSTEM
When filling the brine system, mix the water with antifreeze
in an open container. The mixture should be protected
against freezing down to about -15°C. The brine is topped
up by connecting a filling pump.
1. Check the brine system for leakage.
2. Connect the filling pump and return line on the brine
system's filling connection (accessory).
3. If alternative 1 is used (level vessel), close the valve un-
der the level vessel.
4. Close the reversing valve in the filling connection.
5. Open the valves on the filler connector.
6. Start the filling pump.
7. Fill until liquid enters the return pipe.
8. Close the valves on the filler connector.
9. Open the reversing valve in the filling connection.
10. If alternative 1 (level vessel) is used, open the valve un-
der the level vessel (CM2).
