Connection to supply of untreated water (normal city water)
Install the MELAdem
®
45 reverse-osmosis system in accordance with the installation instructions provided
with the MELAdem
®
45 system.
Connect the MELAdem
®
45 reverse-osmosis system to a supply of untreated water (with a 6
1 hose) to a
tap from the normal tap water supply (Item 10), by means of a 3/4" inside thread / hose connection (hose
adapter 6
1, see Item 16), as provided from the Drain Set. If a separate water tap is not available for con-
nection of the water-treatment system to an existing washup sink, then the existing angle-type non-return
valve may be replaced by another valve with 3/4" outside-thread connection.
Installation of the leak monitor (optional)
If the water-treatment system is connected to a 3/4" normal water tap, then a leak monitor (shuts off running
water in case of leaks) can be installed as option. The shutoff valve (Item 9) must then be directly connected
to the normal city water tap by means of the union nut. The hose adapter (Item 16) must be screwed on at
the outlet of the solenoid valve, and the untreated tap water connection hose must be connected to the ME-
LAdem
®
45 reverse-osmosis system. Plug the leak monitor (shuts off running water) (Item 25) into an elec-
trical socket, and install the electrical leads from the shutoff valve and the leak sensor (Item 27).
Connection of the control unit for external water refilling (external solenoid valve) / pure-water con-
nection
Screw the control unit for external water refilling (external solenoid valve, Item 2) onto the connection for
water feed [39] on the rear side of the autoclave. Connect the power cable of the valve to the socket of the
solenoid valve for water feed [76] on the autoclave. Connect the incoming-feed hose from the MELAdem
®
45
reverse-osmosis system to the threaded fitting of the control unit for external water refilling, at the external
solenoid valve, Item 2.
Wastewater connection
Use the union nut to connect the Y-fitting of the Drain Set (Item 11) to the existing 1" branch of the washup-
sink trap.
Important:
Install the two back-pressure valves, with the aid of the guide grooves provided, into
the free ends of the Y-fitting.
Connection of the autoclave overflow
Use the elbow coupling to connect the overflow hose (Item 23) to the overflow fitting [68] of the autoclave,
and to the hose nozzle connector and union nut (Item 14) on the Y-fitting.
Important:
When installing the
overflow hose, make sure that the hose passes
continuously downward
, without any upward curve.
Wastewater connection of the MELA
dem
®
45
reverse-osmosis system
Connect the wastewater hose of the MELAdem
®
45 reverse-osmosis system to the free branch of the drain
Y-fitting, by means of the hose adapter for the 6
1 hose (turning piece with G1/4", inside threads, see Item
12), by using the screwed-in hose threads, 6
1 (Item 17), and the union nut.
Connection of overflow for the condensate container (optional)
The user can install an optional overflow at the condensate container, to provide automatic emptying of the
condensate container. Remove the dummy plug from the overflow fitting of the condensate container, and
connect the overflow tube (item 18) with its pipe elbow to the overflow fitting.
Use the Y-fitting (Item 13) and the threaded hose connection for hose, 8
1 (Item 15), of the Drain Set to
connect the overflow tube to the drain, together with the drain connection of the MELAdem
®
45 reverse-
osmosis system.
Install the overflow tube in such a manner that the tube passes
continuously downward
, without any up-
ward curve. The maximum permissible level difference between the drain fitting on the trap and the overflow
fitting on the condensate container is + 0.5 meters.
