1. Installation
1.1.Overview of appliance _______________________________________________________
1 Cutter 5 Main switch
2 Pressure rail 6 Signal lamp
3 Sealing rail 7 Mounting provisions for working platform
4 Lever with cylindrical knob 8 Knob for temperature regulation
1.2.Power cable and pressure lever ______________________________________________
The power cable should be plugged into a
230V/50Hz safety socket with earthing.
Then switch the power on (5). The MELAseal 100
will now warm up for about 2 minutes, and is ready
for use when the signal lamp (6) is no longer
illuminated.
The pressure lever can be inserted at either the
bottom right or bottom left side of the appliance.
1.3.Sealing temperature_________________________________________________________
The MELAseal®100 has a very precise regulation
system for the sealing temperature, which is
adjusted by turning the temperature knob (8). With
the transparent packaging material such as
MELAfol®most commonly used in autoclaves by
doctors and dentists (one side paper - one side foil
as described in DIN 58953 Part 4) the temperature
knob (8) should be set to the first third of the area
marked with "MELAfol®". Turning the knob anti-
clockwise lowers the heating power, turning
clockwise increases it. As long as the same
packaging material is being used, it is then not
necessary to adjust the sealing temperature again
during the sealing operations.
The MELAseal®100 package sealing device
produces seals of constant high quality when used
with transparent sterilisation packaging material. The
paper side should always be next to the sealing rail
(3). Tubular foil materials should not be used
because these tend to adhere to the sealing rail.
1.4.Wall mounting _____________________________________________________________
Holes are provided for wall mounting of the
MELAseal®. These are 22 cm apart. The appliance should only be mounted on load-bearing walls using
S 6 plugs.

2. Every-day use
2.1.Sealing procedure __________________________________________________________
When the signal lamp (6) goes out you can begin to
produce seals.
Note: The sealing rail is always hot!
Feed the transparent sterilisation packaging
between the pressing rail (2) and the sealing rail (3),
with the paper side downwards. The sealing impulse
is generated by pressing down the lever until this
engages. This ensures that the sealing pressure is
maintained automatically.
Note! If the lever is not pressed down far enough,
sealing pressure may not be adequate and the
quality of the seal can suffer. The lever should not
be released while the seal is being produced, which
takes about 4 seconds. The process is terminated
by returning the lever to the vertical starting position,
and sealing can be repeated as required, if the main
switsch is not switch off.
2.2.Packaging cutter ___________________________________________________________
The cutting blade (4) must be dragged quickly
across the foil using the round black knob (1). If the
blade is moved too slowly then the sterilisation
packaging will not be cut properly but will only
wrinkle up. The cutting blade functions when moved
to the right and to the left.
2.3.Working with packaging rolls _________________________________________________
Lay the roll in the holder as shown in the diagram,
inserting it from behind between the pressure and
sealing rails and leading it out at the front. The paper
side must be underneath, so that this is in contact
with the sealing rail (3). Pull out the foil to the length
required, seal and cut off. Insert the item for
sterilisation in the bag formed and seal the open
end.

3. Accessories
3.1.Work platform______________________________________________________________
The sealing rail is 250 mm wide, so that it is possible
to seal several narrow packages next to one another
in one sealing operation. The work platform, which
can be attached at the two mounting points (7) at the
front of the MELAseal® Package Sealing Device,
makes it easier to seal packages, especially if these
contain heavy instruments.
MELAG Art. No. 104
3.2.Unit-mounted roll holder "Comfort"____________________________________________
The "Comfort" unit-mounted roll-holder can be used
to save space by mounting the rolls of sterilisation
pack directly onto the MELAseal® Package Sealing
Device. Bolts are supplied to attach it to the rear
side of the Sealing Device.
MELAG Art. No. 105
3.3.Wall-mounted roll holder_____________________________________________________
If the MELAseal®Package Sealing Device is placed
against the wall, or if it is mounted directly on the
wall, then it is best to have a wall-mounted roll
holder positioned directly above it. The wall-mounted
roll-holder can also be installed in a wall cupboard
above the package sealing device, and the
packaging foil fed through a slit in the base of the
cupboard.
Three different positions can be selected, depending
on the width of the roll used, in order to ensure that
the packaging foil is fed properly to the package
sealing device.
MELAG Art. No. 106
3.4.Acrylic hood _______________________________________________________________
The acrylic hood fits over either the "Comfort" roll
holder or the wall-mounted roll holder, to protect the
packaging roll from dust, soiling, etc.
MELAG Art. No. 107
3.5."Standard" roll holder _______________________________________________________
The "Standard" roll holder can be used to hold the
packaging role directly on the MELAseal®Package
Sealing Device. This roll holder is fixed on the two
mounting points on the rear side of the package
sealer.

4. Servicing
4.1.Exchanging the pressing rail _________________________________________________
Note: Let the appliance cool down first to avoid
risks of burns. Then disconnect the appliance
from the mains power supply. (This is important
for all repairs, maintenance and servicing work).
Unscrew the round knob (1).
Undo the four fastening screws and remove the
cover of the pressing rail.
Note: The cutting blade is very sharp!
The pressing rail (2) is now visible. Remove the
screw at the right or left end of the rail and taking the
opposite end of the rail pull it sideways.
Insert the new pressing rail, screw it in place. When
replacing the cover make sure that the axis of the
cutting carriage runs freely along the slit. Finally
screw the round knob back on.
4.2.Exchanging or turning the cutting blade _______________________________________

5. German DIN regulations
5.1.Width of sealed seams and clear space ________________________________________
German Standard DIN 58953 Part 7 requires that
sealed seams in transparent packaging material
should have a width of at least 8 mm. With a width of
10 mm for its sealed seams, the MELAseal® 100 is
considerably better than this minimum requirement.
DIN 58953 Part 7 specifies that a clear space of at
least 30 mm be left below the sealing border
between the sterilisation goods and the seam in
order to ensure a perfect seal without wrinkles. This
applies both for bags and transparent material from
the roll.
5.2.Storage life ________________________________________________________________
Sterile goods packaging Type of packaging Length of storage
unprotected 1Length of storage

Paper bags in accordance
with DIN 58 953 Part 3 Sterile goods single packaging 24 hours 6 weeks

1) E.g. on shelves
2) E.g. in cupboards or drawers
3) Before opening sterile-goods store packaging, dust shall be removed from it in accordance with
regulations.
4) The storage life of sterile-goods store packaging which has been opened is not altered if it has been
closed again in accordance with regulations.
A comment on the table in Section 8.2 of the DIN
standard says:
"The information in the table only represents
standard values. These do not mean that longer
storage periods are not possible under particularly
favourable storage conditions, or that a longer
duration of storage necessarily leads to the pack
contents being recontaminated during storage, but
signify that if these periods are observed,
recontamination of the contents when they are
opened and correctly removed is extremely
unlikely."
An additional explanatory note goes into further
detail:
"The risk in storing sterile goods is not that micro-
organisms may penetrate the sterile goods
packaging, provided that dry storage conditions
are ensured and the packaging material has the
required germ-proof qualities, but that when the
sterile goods packaging is opened after storage,
micro-organisms contained in dust particles may
be stirred up and could recontaminate the sterile
objects when these are removed.
"The extent of dust loading depends upon the
dust content of the air and on the duration of
storage. For these reasons the storage period
should be kept as short as possible."
5.3.VDE regulations ____________________________________________________________
In accordance with current VDE regulations, this appliance is not suitable for use in areas at risk of
explosion.
It should only be serviced by the manufacturer or a specially authorised agent (dealer or customer service).
