Caution
Insufficient venting can damage internal com-
ponents in FLM S45.
FILLING AND VENTING THE BRINE SYSTEM

protected against freezing down to about -15°C. The
brine is topped up by connecting a filling pump.

pansion vessel.
2. Check the brine system for leakage.
3. Connect the filling pump and return line on the brine
system's filling connection (accessory).
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. Vent the brine system with vent valve (QM21) on
FLM S45.
9. Close the valves on the filler connector.
10. Open the reversing valve in the filling connection.
