Replacement Of The Resin Cartridges; Precautions To Avoid Water Contamination; Operation Of The Demineralizer - W&H Dem 32 Manual Del Usuario

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 this
threshold.
1. Close the inlet tap
2. Release the pressure by using the spray gun (check that the spiral tube's connecting tap is
open during this operation).
3. Follow the steps as described in chapter "MOUNTING OF THE RESIN CARTRIDGES".
4.
Re-open the inlet tap.

PRECAUTIONS TO AVOID WATER CONTAMINATION

ATTENTION
In accordance with 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.
As shown in the Installation section, the demineralizer can be used in two ways:
Manual use: the water pistol can be used to manually fill the sterilizer water tank and also to rinse
instruments;
Automatic use: 1 or 2 sterilizers that are suitable for use with the device ( see sterilizer user manual)
can automatically be supplied. When the quantity of water in the sterilizer's clean water tank is below
the minimum levels, the sterilizer powers the external device (at 24Vdc) via the interface cable and
water is automatically supplied to the sterilizer. During the filling of water, the sterilizer's on board
conductivity metre monitors the water conductivity.
When the filter resins or the upstream treatment system are becoming over-consumed, the
conductivity value increases and when the maximum level is reached a corresponding warning
message is displayed on the sterilizer's touch screen.
