___________________
The connection between the components of the system is provided by the hose delivered with the
equipment (outside diameter = 6 mm; hose-wall thickness = 1 mm; MELAG article no. 28820).
Important: do not allow the plastic hose to be twisted or curled or mashed (compressed).
The MELA
dem

Steps to follow for installation of MELA
dem
®
40
1. Make sure that the MELA
dem
®
40 has been correctly attached to the autoclave, and that the mixed-
bed-resin cartridges are properly installed.
2. Close the tap water line.
3.
Important Note:
Start the Vacuum Test program. Stop this program after it has run approx. 20
seconds. This will dispel the remaining water pressure in the system.
4. Unscrew the cooling-water feed hose (12) from the unit.
5. Screw the cooling-water branch fitting (11) into the unit. Screw the cooling-water feed hose (12) onto
the cooling-water branch fitting (11).
6. Now attach the plastic hoses (3) to the MELA
dem
®
40 (2). Attach the feed hose (11) to the
MELA
dem
®
40 to the left elbow fitting. Attach the output hose (3), from the MELA
dem
®
40 to the
autoclave, to the right elbow fitting of the MELA
dem
®
40.
7. Attach
the
MELA
dem
®
feed-water filter (5) in-line to the plastic hose.
8. Make sure that all line connections are tight, and that there are no leaks.
9. Open the tap water line.
If MELA
dem
®
40 is installed directly to the water tap, we recommend using a MELAG Waterstop valve (MELAG art-
no. 01056). In the event of leaks or overflow during operation, the moisture sensors of the Waterstop valve,
installed on the floor, will activate a solenoid valve to shut off the tap water supply.
With the spray pistol MELA
jet
®
(1) instruments can be cleaned or rinsed after disinfection with
demineralized water before sterilization.
