Chapter 1 – Performance Specifications
Proper use
This sealing device is designed for application in a medical context, e.g. clinics and medical and dental
practices.
It was developed for the heat sealing of instruments in sterilization packaging.
Suitable materials
It is suitable for the heat sealing of transparent sterilization packaging according to DIN EN 868-5 such as
e.g. MELAfol.
Should you wish to use packaging materials other than those specified above, please consult your stockist
first or contact MELAG directly.
Unsuitable foils and materials

Transport and storage
WARNING
The use of unsuitable transport packaging can result in damage to the housing and the
device interior.
The sealing device should only be transported in its original or otherwise suitable packaging.
Storage
The device should be stored in such a way to protect against humidity.
Conditions of storage and installation
In accordance with current VDE specifications, the sealing device is unsuitable for operation in areas
exposed to the danger of explosion.
The sealing device is conceived for use outside patient surroundings. The device should be located at
least 1.5 m away (radius) from the treatment area.
Observe all the information contained in this chapter during commissioning.
DANGER
Damages to the sealing device and/or injuries can occur in case the installation conditions
are not observed.
Requirements of the set-up location
Observe the following requirements:
The site of setup is dry and dust-protected.
Sufficient clearance to the surrounding surfaces is available in order to ensure sufficient
ventilation.
The sealing device is located away from direct sunshine and outside the range of other sources of
heat
The sealing device is protected against blows or vibration.
Wall mounting
If the device is not to be placed on a table, it can be mounted on a wall.
If this is the case, we recommend using the wall-mounted roll bracket optionally available.
Proceed as follows:
1. Remove the perforated metal wall-mounting metal panels from the base of the sealing device.
2. Drill two Ø 6 mm boreholes in the wall with a clearance of 16.5 mm at the desired mounting
height.

3. Insert two rawl plugs (6mm) with round-head screws (Ø3.5 x 45 mm) in the bore holes.
4. Hang the sealing device on the screws.
Connecting the sealing device
Connecting the sealing device
Check the following before connecting the sealing device:
The device power switch is off.
The power cable included in the scope of delivery is used for connecting.
1. Connect the one end of the power cable with the port on the rear of the sealing device and the
other end with a mains socket with an approved voltage supply (in accordance with the name
plate on the rear of the sealing device).
2. Insert the lever in the square hole on the left or right-hand side of the device as required (Fig.
1/(4)).

Switching on the sealing device
Activate the sealing device at the power switch.
The LED at the front of the sealing device (Fig. 1/(2)) will illuminate yellow after switching on. As soon as
the control lamp is continuously illuminated green, the pre-set sealing temperature has been reached and
the sealing device is ready to operate.
Simple sealing procedure
DANGER
The sealing bar is heated continuously after the sealing device has been switched on. The
surrounding metal components are hot!
Touching the hot metal surfaces can cause burns.
Never touch the metal surfaces on the cutting bar and on the rear and fore paper guide
directly.
In order to perform a simple sealing procedure, proceed as follows:
1. Introduce the packaging in the paper guide with the foil side facing upwards and push the
packaging through the pressure bar and sealing bar. Ensure maintenance of the correct
clearance between instrument and seal seam (consult the relevant section of the DIN
Specifications).
WARNING
The film side of the packaging must always face upwards. Should the packaging be inserted
incorrectly, this could result in the deposit of film residue on the sealing rail.
