Electromagnetic environments
When assessing the Electromagnetic Compatibility (EMC) of this device, the emitted interference threshold
values for Class B devices and the stability for operation in an electromagnetic environment as described
in IEC 61326-1 were taken as the basis. The device is thus suitable for operation in all institutions and
domestic settings connected to a public mains power supply. The floor should be made of wood or
concrete or be tiled with ceramic tiling. If the floor is fitted with synthetic material, the relative humidity must
amount to a minimum of 30%.

Maintain the side clearances when installing the steam sterilizer.
The steam sterilizer works with a cooler on the rear of the device. The function and life-span of the steam
sterilizer can be compromized if heat dissipation via the cooler is restricted in any way. The steam sterilizer
may only be installed if sufficient air circulation can be guaranteed.
Additional space requirement for the feed water supply
Additional space is required for a storage container or a water treatment unit. It is also necessary to
guarantee free access to the hoses and cables leading from the steam sterilizer to the water treatment
unit.

Implement the following safety measures when dealing with the cable and power plug:
uNever damage or alter the power plug or cable.
uNever bend or twist the power cable.
uNever remove the plug by pulling on the power cable. Always take a grip on the plug.
uNever place any heavy objects on the power cable.
uNever run the power cable over areas in which it could become trapped (e.g. doors or windows).
uNever lead the cable along a source of heat.
uNever use any nails, paper fasteners or similar objects to fix the cable.
uShould the power plug or cable suffer damage, switch off the device. The power cable or plug should
only be replaced by authorized technicians.

Water stop For insurance reasons, MELAG recommends the installation of a water stop
with a cut-off valve (e.g. from MELAG), as the MELAdem 40 / MELAdem 47
are under constant water pressure from the domestic water supply.
PLEASE NOTE
The outlet hose must be fitted at a constant decline without kinks or sagging. Deviations
to the installation arrangements require consultation with MELAG.
Failure to do so can result in malfunctions of the steam sterilizer.
Protection in accordance with EN 1717
The connection of the steam sterilizer to the water supply is comparable with the connection of a washing
machine in a domestic context. In general, the connection of consumers to the drinking water network
should be performed in accordance with EN 1717, so that the drinking water supply is protected against
contamination through the possible flow back of the water. The steam sterilizer was developed in accord-
ance with all the requirements of EN 1717 and is equipped with a pre-fitted safety combination on its rear
panel.
Many buildings are already equipped with a safety combination. Ask your plumber. In practice, it is often
advantageous to use a water inflow tap with a pre-fitted safety combination consisting of a back-flow
preventer and a pipe aerator. To ensure a standard-conform connection to the steam sterilizer
independently of the building installation, we recommend two versions, see section Connecting the cooling
water inflow hose.

3 Setup and installation
WARNING
Improper installation may lead to a short-circuit, fire, water damage or electrical shock.
This could result in serious injury.
nOnly have the device set up, installed and started up by people authorized by MELAG.
Removing from the packaging
CAUTION
Danger of injury from incorrect carrying.
Lifting and carrying too heavy a load can result in spinal injury. Failure to comply with
these provisions can result in crushing.
nThe device should always be carried by two people.
nUse the correct carrying straps to carry the device.
nComply with the safety regulations issued by your professional association.
1. Remove the steam sterilizer from the box using the carrying straps.
2. Unscrew the four screws from each side of the unit cover to remove the straps.
3. Then re-screw these screws without the flat washers.
4. Store the carrying straps and washers in a safe place.
5. Open the door and remove the trays and accessories immediately after switching on the device.
Aligning the door seal sealing lip
Long periods of storage with the door closed can result in the sealing lips of the door seal becoming stuck.
Align the sealing lips to prevent leaks.
Proceed as follows:
1. Remove the door seal.

3 Setup and installation

2. Press your thumb between the two sealing lips and
separate the sealing lips once around with your
thumb.
PLEASE NOTE
Note the differences in the widths of the sealing surfaces when inserting the door seal.
The door can only be shut correctly and the sterilization chamber sealed, if the door seal
sits correctly in the groove.
3. Insert the door seal into the groove.
ÊThe wide sealing surface points towards the
chamber.
