REPLACEMENT OF THE RESIN CARTRIDGES
When used with a sterilizer, replace the resin cartridges when the water conductivity reaches a value of 15
μS. Most sterilizers generate a display message once the water quality drops below a certain threshold.
1. Close the water supply tap at the front of the
DEMI-One
base.
2. Release the internal water pressure with the water gun.
3. Follow the steps as described in chapter “Mounting of the resin cartridges”.
4. Open the water supply tap.
PRECAUTIONS TO AVOID WATER CONTAMINATION
ATTENTION
In accordance with subsection 4.5 of EN1717, in order to avoid water quality
degradation and bacterial growth due to a tailback of water in the tubes, the
entire system must be drained before leaving it unused for a longer period of
time.
OPERATION OF THE DEMINERALIZER
Once installed and fitted correctly, the demineralizer is able to supply demineralized
water immediately.
ATTENTION
The demineralizer is equipped with a Water Block® valve that cuts off the water flow after a pre-
adjusted volume (5 liters) in order to prevent a large spillage of water in case of a broken tube.
When you take water from the demineralizer with the use of the spray gun and the volume goes
beyond 5 liters, the Water Block® valve will cut off the water supply. To reset the Water Block® valve
see hapter “Maintenance instructions for the safety valve”. To avoid a water cutoff, release the water
gun once every 30 seconds if quantities of more than 5 liters are taken from the demineralizer.
The quantity of demineralized water produced per set of resin cartridges depends on the quality and
hardness of the city water in your area. Refer to the table below for further details:
