While the sludge remover unit is filling, with the compressor running, do not pull the power supply
cable.
3. Open the water supply.
4. Read the minimum flow rate and let it stabilize. If the minimum flow speed of 0.5 m / sec. is not
reached, cleaning cannot be performed properly. In this case, clean the system by segments.
5. Press the “Water + Air (pulses)” program key.
And clean.
6. Alternate the two Pulse cleaning and Continuous compressed air cleaning about every 10min to
clean the installation effectively.
7. The cleaning process is complete when there are no more visible traces of residue at the outlet. To this
effect, we advise to run the water at the outlet of the water points through filtering strainers with a mesh of about
100 μ.
8. After cleaning, stop the sludge removal unit. The compressor must not be running. The filling process (8 bar)
must be finished.
9. Then close the water supply.
10. Disconnect the VIRAFAL® from the electric network.
11. The cleaning controller must be disconnected from the test pipe, all couplers must be fitted properly. A
sealing test must then be performed.
6.3. Cleaning floor heaters
1. Separate the water inlet pipe from the boiler.
2. To protect drinking water, a tube or separator system must be fitted upstream the rinsing
compressor as per EN 1717.
3. Separate the return or close it and fit an evacuation pipe. In addition, the pipe must be
extended and fastened to a sufficiently large evacuation.
4. In case of low water pressure, clean the heating system by section.

7. Then close the water supply.
8. Disconnect the VIRAFAL®

6.4. Special instructions for cleaning drinking water pipes on a new installation (before the 1
st
start-up of
the installation)
As set out in the EN 806-4 standards, recently installed drinking water pipes must be cleaned before use,
knowing that performing this cleaning operation using a pulsated water/air mix improves the cleaning result.
