Disposal
MELAG products are synonymous for long-term quality. When you eventually need to decommission your MELAG pro-
duct after many years of operation, dispose of it and any spare parts that are no longer used, such as seals, properly.
Comply with all relevant disposal specification in terms of possibly contaminated waste.
The packaging protects the product against transport damage. The packaging materials have been selected for their en-
vironmentally-friendly and recycling properties and can be recycled. Returning the packaging to the material flow reduces
the amount of waste and saves raw materials.

Intended use
The reverse osmosis unit with ion exchanger permits the production of }demineralised (de-ionised) water. This requires
tap water of drinking water quality.
PLEASE NOTE
The water treatment unit does not provide low-germ water.
The MELAdem 56 is suitable exclusively for the feed water supply of a single Cliniclave45 or Cliniclave45D. The
MELAdem 56 M is suitable exclusively for the feed water supply of a single Cliniclave45M or Cliniclave45MD. The re-
verse osmosis units are intended for use in the medical field, e.g. in clinics, medical and dental practices and other medi-
cal care facilities outside the patient environment.
The reverse osmosis units MELAdem 56 and MELAdem 56 M are not a medical device within the meaning of European
Regulation 2017/745 on medical devices.
Mode of functioning
The units function according to the reverse osmosis principle. This process presses water through a semi-permeable RO
membrane (osmosis module), reducing the salt content of the cold water by some 95%. The inflowing water is separated
into two flows:
1. Water with a low salt content (permeate)
2. Water with increased levels of salt (concentrate) which is disposed of via the outflow
The produced permeate is stored in the pressure tank, which is connected to the steam sterilizer via a hose. When the
pressure tank is filled, the pump and thus the cold water supply is deactivated. All operating runs of the reverse osmosis
unit are automatically controlled via its water pressure. In this way, even with poor cold water quality, a water quality ne-
cessary for the operation of the steam sterilizer is achieved.

4 Setup and installation
10
4 Setup and installation
Installation location
nInstall the water treatment unit in a clean, frost-free place that can be ventilated.
nThe installation location permits a careful installation, operation and maintenance.
nMake sure that the temperature along the inlet hose does not rise above 40 °C.
nIf 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.
Space requirements
The reverse osmosis unit is installed in the floor unit of the steam sterilizer.
Cold water connection
PLEASE NOTE
MELAG recommends connecting the water treatment unit directly to the drinking water. Connecting
water purification systems or filters that work with oxidants (e.g. chlorine) upstream can affect the
osmosis module and thus impair the performance of the water treatment unit.
Increased requirements can be placed on the quality of the }DI water (e.g. a low endotoxin content) for
the }reprocessing of certain medical devices such as ophthalmic instruments.
Note the following:
nIn such cases, an additional filter system is required for the reprocessing of DI water.
nIt is possible that the drinking water has been contaminated by the water installation. This includes both the domestic
installation and the entire upstream peripherals.
nArrange for the actual drinking water quality to be tested at the point of use or request an appropriate report (e.g.
from the building management) before setting up and installing the water treatment unit.
nFurther information is available from the corresponding trade associations and their publications. If in doubt, contact
your stockist or the pertinent professional association.
Connection of the reverse osmosis unit
The installation described here refers to the connection of the reverse osmosis unit to a fully installed and operational
Cliniclave. If the reverse osmosis unit is installed together with the Cliniclave, proceed according to the installation in-
structions in the technical manual of the steam sterilizer. The work steps are coordinated there to save work and time.
WARNING
Danger of electrical shock!
A voltage of 230V is present at the cable socket for connecting the MELAdem56/56M in the floor unit when
the steam sterilizer is switched on.

NOTICE
Ensure that the hoses do not suffer kinking or crushing.
1. Switch off the steam sterilizer at the power switch.
2. 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. Given
insufficient pressure, increase this pressure using e.g. an air
pump with Schrader valve.
3. Loosen the screws (TX20, pos.a1/2) on the cover of the osmosis
module and pull the cover upwards. Proceed with caution.

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. This can be caused by a high turbidity content in the cold water. In this case, replace the
cartridge of the fine filter as required.
1. Remove the filter container (pos. a) from the container cover (pos.
