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 do-
mestic 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%.

Measures for protecting
the drinking water
We recommend the use of a safety combination consisting of a back-flow
preventer and a pipe aerator (e.g. the assembly set in accordance with
EN1717 for MELAdem) in accordance with EN1717 to protect against
backflow into the drinking water supply.
Leakage water detector We recommend the installation of a leakage water detector with a cut-off valve
(e.g. MELAG water stop).
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.

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.

3 Setup and installation
11
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.
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.

3 Setup and installation
12
Aligning the steam sterilizer
To enable fault-free operation, the steam sterilizer must be setup level using a spirit level placed on the
chamber flange. Then extend the fore device feet by five (Euroklav23VS+) or three (Euroklav29VS+)
revolutions to effect a slight rearwards slope of the steam sterilizer.
Installation examples
Example 1 - Standard delivery state
Direct feed water inflow from the internal storage tank. The wastewater will be collected in the wastewater
chamber of the storage tank. No water connection required.
The steam sterilizer is supplied with feed water directly from the internal storage tank via a hose bridge. A
float switch integrated in the device notifies the absence of feed water. Programs can only be started after
feed water has been filled. The used feed water (wastewater) is collected in the wastewater chamber of
the internal storage tank and is to be emptied manually at a later point. A float switch also monitors the
current water level in the wastewater chamber.

Example 2 - one-way drain via siphon
Direct feed water inflow from the internal storage tank. One-way drain via the surface-mounted siphon.
The steam sterilizer is supplied with feed water directly from the internal storage tank via a hose bridge. A
float switch integrated in the device notifies the absence of feed water. Programs can only be started after
feed water has been filled. The used feed water (wastewater) is discharged via the one-way drain.

Example 3 - MELAdem40
Feed water inflow from the MELAdem 40 ion exchanger.
Connection of the MELAdem40 ion exchanger with MELAjet. The most simple installation is the direct
connection of the MELAdem40 to the steam sterilizer feed water inflow; this generates demineralized wa-
ter from normal tap water. The MELAjet spray pistol is used to perform the final rinse of the instruments
with demineralized water before sterilization.
The used feed water (wastewater) is discharged into the double chamber siphon via the one-way drain.

Instructing the users
▪ Explain all the user-typical features for the documentation and setting combinations for the operator.
▪ Hand over the user manual, the technical manual and the manufacturer's inspection report. The
declaration of conformity regarding the pressure equipment directive and the Medical Devices Act are
included in the manufacturer's inspection report.

Date and time
Check the date and time and set if necessary: consult the user manual.
Feed water inflow
The feed water supply is effected either via the internal storage tank or via a separate water treatment unit
(e.g. MELAdem 40/MELAdem 47). Setup the feed water inflow depending on the installation versionIN-
TERNAL orEXTERNAL.
Further information is provided in the device user manual.
Additional program options
TheAutom. preheating function heats the steam sterilizer chamber to a preheating temperature of
the respective program before program start, or holds this temperature between two program runs. This
will shorten the cycle times. It also reduces condensate formation on the chamber wall.
TheAdditional drying function increases the program by 50% for difficult drying tasks.
Further information is provided in the device user manual.
Counter stands
Working in theSETUP menu menu, you can access counter stands and other technical data of the steam
sterilizer.

ture sensor (see circular marking in the following figure). The temperature in the rest of the sterilization
chamber is almost the same all over.
