3 Product description Views MELAdem 56 10 11 Pos. Designation Description Power supply Supplies the pump with current. Power connector Supplies the power supply with current. Dirt filter Filters the through flowing water to protect the pump. Pressure switch Controls the power supply of the pump. Prevents e.g. a too high pressure increase in the pressure tank.
3 Product description Views MELAdem 56 M Pos. Designation Description Dirt filter Filters the water flowing through to protect the pump. Osmosis module The core of the reverse osmosis unit. Power connector Supplies the power supply with current. Connection for outlet hose Through the outlet hose (length: 2 m, Ø 6/4 mm) the concentrate is discharged via the steam sterilizer into the wastewater.

3 Product description Pos. Designation Description Recessed grip Acts as a carry aid for transport purposes. Permeate line The permeate line (Ø 6/4 mm) runs from the ion exchanger to the pressure tank. Shut-off valve Serves for closing the pressure tank. Manometer Displays the current feed water pressure in the pressure tank.
Make sure that the temperature along the inlet hose does not rise above 40 °C. If the room in which the water treatment unit is installed does not have a floor drain, MELAG recommends a leakage water detector (e.g. water stop from MELAG), which shuts off the water supply in the event of damage via a moisture sensor on the floor and with the help of a solenoid valve.

4 Setup and installation Connection of the MELAdem 56 NOTICE Ensure that the hoses do not suffer kinking or crushing. Switch off the steam sterilizer at the power switch. Measure the primary pressure at the pressure tank with the delivered manometer. The target pressure is 0.6 bar. Should the primary pressure of an empty pressure tank exceed this value, reduce the pressure by pressing in the valve tappet.

5 Commissioning Checking the operating pressure Perform regular checks of the pressure on the pressure tank manometer before first program start. With daily operation, the pressure tank is still sufficiently full from the previous day. The blue pointer shows the current pressure of the water treatment unit. The red pointer is used to check the maximum pressure of the water treatment unit.
6 Maintenance 6 Maintenance Maintenance intervals Interval Measure Daily ▪ Check the permeate with a conductivity meter or with the built-in conductivity measurement of the steam sterilizer. ▪ Check the pressure in the pressure tank via the manometer. Every 12 months ▪...
6 Maintenance Removing and attaching the filter containers Removing a filter container Start the program Conductivity meas. for depressurising the unit. Switch off the steam sterilizer and close the pressure tank shut-off valve. Guide the container key (pos. a) from bottom to top over the filter container (pos. b).
Replacing the fine filter PLEASE NOTE Only use original MELAG consumables and spare parts. The use of foreign parts may result in damage and loss of warranty. Replace the cartridge of the mechanical fine filter (pre-filter) once a year. If there is a high pressure loss, filling the pres- sure tank takes more time.
Replacing the activated carbon filter PLEASE NOTE Only use original MELAG consumables and spare parts. The use of foreign parts may result in damage and loss of warranty. Replace the cartridge of the activated carbon filter once a year or when replacing the fine filter.
Replacing the mixed-bed resin cartridge PLEASE NOTE Only use original MELAG consumables and spare parts. The use of foreign parts may result in damage and loss of warranty. When the mixed-bed resin is exhausted (poor permeate quality), replace the mixed-bed resin cartridge.
6 Maintenance Cleaning the filter insert of the dirt filter Switch off the steam sterilizer at the power switch. Close the pressure tank shut-off valve. Start the program Conductivity meas. for depressurising the unit. Loosen the screws (TX20) from the cover of the osmosis module and pull the cover upwards.
