Safety Instructions

When operating the mixed-bed resin cartridge, please observe the following safety instructions as well as those contained in subsequent chapters.

Maintenance

 Use only original replacement parts for maintenance.

Leaks

 The water intake is to be closed upon the discovery of leaks. Check all hoses and hose

connections for leaks.

Chapter 1 – Performance Specifications

Chapter 1 – Performance Specifications

Intended Use

This mixed-bed resin cartridge works according to the ion exchange procedure. It is used for the complete demineralization of water (DI water) of drinking water quality.

The MELAdem 53/MELAdem 53 C must always be operated with the MELAtherm 10 washer-disinfector. Optionally, further devices can be connected, e.g. one or more steam sterilizers.

Mode of functioning

The mixed-bed resin cartridge is filled with a cation and anion resin which removes the salts dissolved in water using the so-called adsorption process.

The mixed-bed resin is exhausted after absorbing a certain amount of salt and must be replaced and regenerated (see Chapter 4 – Maintenance).

The capacity of a mixed-bed resin cartridge depends on the hardness of the local water supply (see Technical Data).

Chapter 3 – Commissioning

Removing from the packaging

1. Remove the two mixed-bed resin cartridges included in the scope of delivery from the packaging.

2. Store one of the two mixed-bed resin cartridges included in the scope of delivery as a reserve in

accordance with the storage conditions specified on page 20.

3. Retain the MELAG transport packaging (1 folded box, 2 foam inserts) in a safe and dry location.

These are required when returning the mixed-bed resin cartridge for regeneration.

4. Note the serial number of the mixed-bed resin cartridge on the label for control purposes. The

serial number is located on the type plate on the rear of the mixed-bed resin cartridge.

Fig. 2: Label for entering the serial number

Requirements of the set-up location

The following conditions must be given:

 The installation location is clean and frost-free.

 The mixed-bed resin cartridge is installed in a perpendicular position.

 The installation location is freely accessible for the installation, operation and regular replacement

of the mixed-bed resin cartridge.

 The hose connections must be freely accessible.

Space requirements

The space requirement of the mixed-bed resin cartridge corresponds to its dimensions plus a minimum of 25 cm for the safety combination EN 1717 and free access to the hose connections. If the MELAtherm is to be installed as an installation device, this should be placed in an adjacent floor unit.

Requirements for connection to the water pipe

Installation of a cut-off valve with a back-flow preventer and a 3/4" external thread connection in the proximity of the installation location. In order to provide a standard-conform connection for the mixed-bed resin cartridge with back-flow preventer and pipe aerator independent of the on-site installation, we recommend one of the following connections:

PLEASE NOTE

To prevent water damage, we recommend the use of a leak detector e.g. the MELAG water stop (order no. 01056).

Connection to the cold water supply

The water flow pressure of the on-site tap should be a minimum of 1.5 bars and may not exceed 10 bars.

Alternative connection 1

If a separate water connection (nominal width DN15 with 1/2" collar) is present / installed, a water tap with a back-flow preventer and a pipe aerator is installed.

Fig. 3: Installation with back-flow preventer and pipe aerator

Alternative connection 2

If a cold water connection with an angle valve and a Ø 10 mm duct is present / installed, an additional water tap with an integrated back-flow preventer and pipe aerator will be fitted directly to an existing angle valve.

Protection with a safety combination in accordance with EN 1717

The connection of consumers to the drinking water system must be performed in accordance with EN 1717 so as to protect the drinking water supply from pollution. To this end, fit a safety combination of a backflow preventer and a pipe aerator to the connection in accordance with EN 1717 part 4. The safety combination included in the scope of delivery should be mounted on the wall, 25 cm over the mixed-bed resin cartridge (see Fig. 6).
