5. Commissioning
All loose parts, including cardboard and
packaging materials must be removed from
the system before commissioning.
5.1 Filling the brine loop
During standard operation of the ComfoFond-L,
taps V2 and V4 are open and the filling valves
V1 and V3 are closed. The ComfoFond-L is filled
via the filling valves V1 and V3.
The tap is open when the handle is parallel to
the pipe. The tap is closed when the handle is at
a right angle to the pipe.

Filling instructions
Proceed as follows:
1. Disconnect the ComfoAir Luxe from its
power supply.
2. Remove the filter handle from the
ComfoFond-L.
3. Release the front panel by removing the
6 screws.
4. Remove the front panel from the
ComfoFond-L.
5. Check the pre-pressure in the expansion
vessel. In a no-pressure condition, the
pressure must be 0.5 bar.
6. Connect the external rinsing pump to filling
valve V3
7. Connect a drainage hose to filling valve V1.
8. Put the other end of the discharge hose in a
container. We recommend a rinsing system
with an open circuit.
9. Open filling valves V1 and V3.
10. Close tap V2.
11. Open the de-aerator cap.
12. Flush the brine loop until no more bubbles are
visible in the collector of the rinsing pump, but
at least 10 minutes.
Only fill the system with a ready-made brine
mixture. The correct brine mixture can be
determined using the ComfoFond-L
specifications.
13. Close filling valve V1.
14. Open tap V2.
15. Increase the pressure in the device to 1.5 bar.
To that end, use the filling hose connected
to filling valve V3. Use an additional pressure
pump if necessary.
16. Check the system pressure again and add
more in order to increase pressure if
necessary.
17. Close filling valve V3 and disconnect the filling
hose.
18. Adjust the circulation pump to the correct
setting. More information about this is
available in the ‘Adjusting the circulation
pump’ section.
19. Install all parts in reverse order (from point 4
back to point 1).
An installation report has been included at
the rear of this manual which can be used to
note the details of the brine used.
