Example 2: Using the MELAdem 40 ion exchanger
The most simple installation is the direct connection of the ion exchanger to the steam sterilizer feed water inflow; this
generates demineralised water from normal tap water. The MELAjet spray gun can be installed as an option.
NOTICE
When connecting an external feed water supply it is necessary to connect an external wastewater
outflow as well.
There is a risk that hot wastewater might run through the emergency overflow.
To convert to the feed water supply from a water treatment unit, make the following preparations:
1. Empty both chambers of the internal storage tank.
2. Replace the feed water inflow fitting (5) located on the steam sterilizer with the hollow screw with feed water inflow
fitting for hose Ø6x1 (art. no.ME25655) because of the different hose diameter. Both parts are included in the water
connection set (art. no. ME09034). When using a MELAjet spray pistol use the swivel screw connection (art. no.
ME53465).
3. Replace both Cu seals (art. no. ME42360, included in the scope of delivery) for the hollow screw.
In this example, the used feed water (wastewater) is fed directly via the pressure drain into the siphon of the domestic
water network. Use the outlet hose (PTFE hose, Ø8/6mm, art. no. ME39180). Alternatively, the wastewater can also be
directed into the siphon via the one-way drain, see Example 3: Using the MELAdem 47 reverse osmosis unit
[}Page15].
When connecting the water treatment unit directly to the domestic water network, MELAG recommends the additional
installation of the leakage water detector (water stop) with shut-off valve and probe.
