Due to the high-tech resin and carbon in the IEN Filters, there is little need to flush the filters after inactivity of a coffee machine unless that period exceeds 1 month/4 weeks.
As per the guidelines of the WHA (Water & Hydration Association) and WE (Watercoolers Europe) any water or drinks dispenser that has a filter should be drained or flushed after the filter which includes the dispenser. Drainage/Flushing is not necessary in hot water dispensers that are set above 85°C.
After a 4-week period of inactivity the filters should be flushed through for the below minimum amounts in Litres.
|Rinsing Volume Per Filter Model|
|Inactivity Time||1 Day to 4 weeks||Ø 4 Weeks|
Filter Exchange can be kept to Maximum capacity of Resin – NOT 12 months
- All filters can be flushed manually by turning off filter feed or removing cartridge. Removing the outlet pipe to the head and using a short 30cm 3/8 tube to a bucket or container.
- It would be advisable to fit an inline 3/8 isolation valve prior to the filters – or purchase our “Flush valve” and fit after the filter to make this easier in the future.
Flush Valve only £2.50 per unit.
