Operating Manual of the MELAdem

1 Method of operation of the system

MELAdem®40 is a water treatment system that operates according to the ion-exchange process. It is used for the complete demineralization of tap water. The cartridges contained in the filter chamber are filled with mixed-bed resin. The cartridges are disposed of after they have become depleted: they are completely exchanged upon every replacement. The MELAdem

40 reduces the content of salt in untreated water by approx. 95 … 99% (depending on the degree of depletion of the mixed-bed resin). All operational processes in the MELAdem

40 system are controlled by means of the pressure in the tap-

water line. MELAdem

40 can be directly connected to a MELAG autoclave (for example, the MELAG Vacuklav® ,

Vacuquick

or Euroklav® models) to automatically supply the autoclave with demineralized water. The

MELAdem

40 can, however, also be used as a completely separate water-treatment system. The flow

limit of 2 l/min must not be exceeded, however. The MELAdem

40 may be installed onto the wall, in a lower cabinet, or directly at an autoclave.

If the room in which the MELAdem

40 water treatment system is to be installed does not have an open

drain in the floor (to catch overflow), 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.

IMPORTANT: If the MELAdem

40 water treatment system is out of operation, the user should close off

the supply of the tap water system.

2 Design of the system

The MELAdem®40 mixed-bed resin system is delivered in pre-assembled form. Please see Figure 1 for a description of the individual components of the MELAdem

40.

IMPORTANT: It is absolutely necessary to ensure the correct flow direction

of the water. Please see

Figure 2 for

the position of the incoming water feed and the outgoing supply points for the

MELAdem

40.

housing.

4 Housing

The housing protects the filter unit and is used to store the filter housing wrench.

5 Hose connection

The hoses (MELAG order no. 28820) connected to the elbow unions enable tap water to flow into the MELAdem

40, and

demineralized water to flow out.

6 Elbow and dual unions

These threaded unions, coated with Teflon, connect the hose to the container elements, and connect the container elements to each other.

7 Resin container elements

In these two containers, tap water flows through the mixed-bed resin cartridges.

3.7.1 Conformity with the hygienic stipulations of EN 1717________________________________________

You must connect your

MELAdem®40 to the tap-water mains in accordance with EN 1717, in such a manner that

your system will not contaminate the drinking-water network. For protection of a drinking-water network to which an autoclave is connected, EN 1717, Part 4, stipulates that a

combination of the following two units on the rear wall of the autoclave must be installed: a return-flow inhibitor (non-return valve) together with a backsiphonage preventer. In many buildings, this protective equipment is already installed. To be sure, please consult your plumbing and installation specialists!

Steps to follow for installation of MELAdem®40 :

1. Warning: First switch off the unit and pull out the power plug.

2. Remove the housing cover of the autoclave.

3. Place the drilling template onto its correct position, and drill 2 x 4.2 mm holes in the unit housing.

4. Use the centrally drilled holes in the mounting fixtures (see Fig. 10) to fasten the metric screws (M4, 20 mm) from the inside with tooth lock washers and nuts.

5. Replace the housing cover of the autoclave.

6. Hang in the MELAdem®40 vertically from above, and slide it downward, until the housing of the MELAdem®40 locks into the mounting fixtures.

especially installed. Installation of a water faucet with integrated safety combination (MELAG article no.

37310).

Variation II: Cold-water connection (for example, for a sink) with an angle-type non-return valve and hose (10 mm) already exists, or will be especially installed. Installation of an additional water faucet with integrated safety combination (MELAG article no. 58130), by direct installation to an existing angle-type non-return valve.

Instructions on the hose connections for the MELAdem

Use a hose-cutter, or a sharp knife, to cut 2 pieces in the required lengths from the hose included in the delivery (article no 28820). At the plastic fast-screw connections, use a plastic union nut to connect the hoses to the MELAdem

at the incoming water feed (this is the right

connection, as seen from the front, when the printing

“MELAdem

40” is visible). At the output water feed, this is the left connection, as seen from the front,

when the printing “MELAdem

40” is visible. The first step is to slide the union nut onto the end of the hose. Then shove the hose until it will go no farther onto the socket of the fast-screw connections, on the right and left connections of the MELAdem

40. Then shove the union nuts up to the threads and screw them on finger-tight. Make the connection of the free end of the hose to the water input, or to the consumer (depending on the installation variation selected: see Fig. 11). Use a metal

fast-screw connection for this purpose. The first step here is to shove the metal union nuts onto the ends of the hoses, then push the hoses until they will go no farther onto the socket of each of the metal fast-screw connection. Then tighten the metal union nuts finger-tight, and then screw then about ¼ turn more with an open-end (engineer’s) wrench.

3.7.3 Installation of the water quality monitor (optional) ___________________________________

If the autoclave connected to the water treatment unit does not perform conductivity measurement, the quality of the fresh purified water (aqua dem) can be inspected with the control monitor for water quality. An internal conductivity measurement is integrated in MELAG autoclaves*. Therefore it is not necessary to install the control monitor.

* as for Vacuklav®, Euroklav® und Vacuquick®

Installation of the conductivity sensor

1. Install the conductivity sensor, i.e. the T-piece with mounted conductivity probe, between the outlet side of the

MELA

dem

40 (fig. 2, pos. 2) and the feed water inlet to the autoclave by disconnecting the inflow hose towards

the feed water inlet and inserting the T-piece.

2. Connect the cable of the conductivity sensor to the control monitor (connection “Probe”).

Adjusting the conductivity limit value on the control monitor

1. The housing lid is loosely positioned on the control

monitor upon delivery. Take off the housing lid.

2. The conductivity limit value is adjusted to 0.5 S/cm upon

delivery. The blue jumper can be repositioned as needed. The numbers to the left of the PINs indicate the conductivity limit value.

Position of jumper 1 2 3 4 5 6 7 8 Limit value in S/cm

0.5 1 2.5 5 10 20 50 100

3. Put the lid on the housing and fasten it to the bottom with

the four supplied screws. Then mount the grey covering caps.

4. Insert the two supplied batteries (1.5 V AAA) into the battery compartment on the bottom of the control monitor.

Attachment of the control monitor

5. Attach the conductivity monitor to an easily accessible and well-visible place, i.e. using a double-sided

adhesive tape on the rear side of the control monitor.

6. Remember that the maximum length of the connection lead is 0.8 m.

4 Putting into operation

First carefully install the components. This includes the following: Install the new mixed-bed-resin cartridges by following the instructions for exchanging

the cartridges (see Section 5.1.1 below). Then

hook up the threaded hose connections. Then place the MELAdem

40 into operation by carrying out the following steps:  Open the tap water line and check if the MELAdem

40 has no leaks and that all hoses are connected

tight.

 The first filling of the MELAdem

40 takes approx. 5 minutes (depending on water pressure from the tap). This first filling is necessary to provide enough treated water for the autoclave or another consumer (for example, a MELAjet

 Before first putting into operation, and after changing the mixed-bed-resin cartridges, be sure to run

one empty sterilization cycle with the autoclave, before the first full run with instruments in the machine.

5 Maintenance instructions

Be sure to perform the following maintenance work, in the time intervals given below, to assure satisfactory functioning of the system:

Interval Maintenance work

Daily Check the demineralised water with a conductivity measuring unit, the

conductivity monitor, or by the built-in conductivity measuring unit in an autoclave

6 months Check the hoses and threaded connections to make sure that they do

not leak. Check the hoses to make sure that they are not kinked (twisted), and that they are not mashed (compressed). Make sure the hoses have not become brittle with age.

As needed Exchange the resin in the container element after you have used

approx. 120 litres of demineralised water from the unit. The exact amount will depend on the quality of the tap water. If the MELAdem®40 is connected to an autoclave with a conductivity sensor (e.g., from the Vacuklav® / Euroklav® / Vacuquick®lines), then the indicator on the autoclave display will show when the resin in the cartridge must be exchanged.

Page 20

5.1 Exchanging the mixed-bed-resin cartridges__________________________________

5.1.1 Complete exchange of the mixed-bed-resin cartridges_______________________________________

When the mixed-bed resin becomes exhausted, the output water quality will become poor. Exchange both of the mixed-bed-resin cartridges as follows:

 Close off the supply of tap water (i.e., turn off the faucet)  Warning! Important for pressure release: If the system is connected to an autoclave from the

Vacuklav

/ Euroklav® / Vacuquick® lines, start the program “Vacuum test”. Then interrupt the program after approx. 20 sec. by pressing the Start/Stop button. These measures will release the water pressure remaining in the systems. If the water-treatment system is not connected to an autoclave, then normal delivery of the water to the MELAjet

will release the water pressure.

 Remove the cover of the MELAdem

40 to gain access to the filter wrench.

 Remove the wrench from the MELAdem

40 (see Figure 17).

Figure 17: Removing the filter wrench

 Slide the wrench from the bottom onto the filter enclosure, and move it up toward the top as far as will

go. Allow it to lock into place there. Open each of the container elements by turning the wrench clockwise (as seen from above): see Figure 18). As soon as the container elements can be easily turned, you can remove

the wrench and unscrew the elements by hand for the last turns..

 Now pull the container elements off, toward the bottom. Caution: the container elements can be

completely full of water. Then remove the depleted mixed-bed-resin cartridges. You can dispose of

them as normal domestic waste.

 Rinse out the container elements thoroughly under flowing water.
