20. Switch the Quantum into dumping mode.
21. After dumping for ten minutes (with
coil and all radiators wide open),
test the dump water with pH paper.
Continue dumping until a pH
reading of 7 is reached, or the
same reading as the mains water
supply in the property is achieved (both samples
show the same colour).
Note: As an alternative an electronic pH meter
may be used (see page F.11)
22. If you have a TDS meter (Total Dissolved Solids)
it is useful to test the water at this stage.
The reading should be compared with a mains
water sample reading, and the dumping process
continued until both readings are within 5% of
each other.
23. Return to re-circulation mode and move to page
B.10.
