12.7 Hygiene flush (Automatic)
The programming unit should be held pointing towards the sen-
sor at distance of approx. 100mm.
Once enabled, this function will automatically turn the water on
for a duration of 1 to 240 seconds if the product has not been
used for a period of 6, 12, 24, 48, or 72 hours.
This hygiene flush is an important optional function of these products which can be enabled by the in
-
staller or maintenance staff using the optional remote programming unit (for part number see sect.18).
The hygiene flush is used to combat periods of stagnation due to low usage of the product. The func
-
tion activates the spout automatically if it hasn’t been used for a set time period. This function ensures
regular movement of water combating bio film growth and bacteria colonisation.
For full details on how to enable this function, refer to the
programming instructions supplied with programming unit.
