1 Installation
1.1 Overview of appliance________________________________________________
Illustration 1 Overview of appliance
1 Cutter 5 Knob for temperature regulation
2 Handle 6 Paper guide
3 Main switch 7 Upper rear enclosure hood
4 Signal lamp 8 Upper enclosure front
1.2 Power cable and pressure lever________________________________________
The power cable should be plugged into a 230 V / 50 Hz safety socket with earthing.
Then switch the power on (Illustration 1 item 3). The MELAseal®100 will now warm up for about 2 minutes,
and is ready for use when the signal lamp (Illustration 1 item 4) is no longer illuminated.
The pressure handle (Illustration 1 item 2) 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 (Illustration 1, item 5). With the transparent packaging material such as
MELAfol®most commonly used in autoclaves by doctors and dentists (one side paper and one side foil, as
described in DIN 58953 Part 4) the temperature knob (Illustration 1 item 5) should be set to the first third of
the area marked with "MELAFOL". Turning the knob anti-clockwise lowers the heating power, and 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.
With use of see-through sterilization packaging, the MELAseal®100 Package Sealing Device always
produces uniform sealing seams with a width of 10 mm (DIN 58953 requires at least 8 mm). This requires,
however, that the operator place the paper side downward onto the sealing rail. Tubular film materials should
not be used, because they tend to adhere to the sealing rail.

1.4 Wall mounting ______________________________________________________
The MELAseal®100 "economic" has been prepared for installation on the wall. Use the prepared holes in the
bottom, which you can open by breaking out the metal parts. Use a screw, for example, to break out the
metal plugs toward the outside (see Illustration 3), by gently moving them back and forth at the already
perforated places (Illustration 2, no. 9 + 10). The interval between the holes on the wall is 16.4 cm. Caution:
Be sure to place the device only on walls that are strong enough to support the weight of the unit – and make
sure to use 6 mm wall anchor plugs in the holes, as well as round-head screws (∅3.5 mm ×45 mm).

2 Every-day use
2.1 Sealing procedure ___________________________________________________
When the signal lamp (Illustration 1 item 4) is no longer illuminated you can begin to produce seals.
Warning: The sealing rail is always hot!
Feed in the transparent sterilisation packaging with the paper side downwards. Place the sterilization
package, with the paper side down, under the rear paper guide. Then move the package toward the front
between the pressure bar (top) and the sealing rail (bottom). The sealing pressure is generated by pressing
down the handle (Illustration 4 item 2) until it engages. This ensures that the sealing pressure is maintained
automatically.
Warning: If the handle (Illustration 4 item 2) is not pressed down far enough, sealing pressure may not be
adequate and the quality of the seal can suffer. The handle (Illustration 4 item 2) 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 switch is not
switched off.
2.2 Packaging cutter ____________________________________________________
The cutting blade must be dragged quickly and with light pressure across the foil using the black cutter
handle (Illustration 4 item 1), and with the switch handle (Illustration 4 item 2) pressed as far as it will go. 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__________________________________________
As shown in Illustration 4, slide the rolls onto the roll mounting rod, position them with the side guides
(Illustration 4 item 20), move the packaging under the rear angled paper guide (Illustration 1 item 6), and
guide them through toward the front, between the sealing rail and the pressure bar. The paper side must be
downward: i.e., it must lie on the sealing rail (down). Then pull the packaging in the required length toward
the front, seal the package, and then cut it off.
Place the objects to be sterilized in the package that you have now made. Guide the open end from the front
between the sealing rail and the pressure bar, and seal the package. The width of the sealing rail enables
you to work with packages up to a width of 250 mm.

3 Accessories
3.1 Unit-mounted reel dispenser "comfort" _________________________________
The "Comfort" unit-mounted roll-holder (Illustration 4 & Illustration 5) - MELAG item number. 111 - can be
used to save space by mounting the rolls of sterilisation pack directly onto the MELAseal®100 Package
Sealing Device.
Use the two rear enclosure screws (Illustration 5 and Illustration 8 item 13) to attach the roll mount to the rear
of the MELAseal®100 Package Sealing Device.

3.2 Wall-mounted reel dispenser __________________________________________
If the MELAseal®100 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
reel dispenser - MELAG item number. 106,
(Illustration 6) - 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.
Four (4) side guides are provided for each reel
dispenser, to ensure proper positioning of the rolls
of sterilization packaging.
Illustration 6 Wall-mounted reel dispenser
3.3 Reel dispenser “standard” ____________________________________________
The reel dispenser "standard" – MELAG item number 110 – can be used to hold the packaging role directly
on the MELAseal®100 Package Sealing Device. This reel dispenser is fixed on the two mounting points on
the rear side of the package sealer (Illustration 7 and Illustration 8 item 19).

4 Servicing
4.1 Exchanging the pressure rail __________________________________________
Note: Let the appliance cool down first to avoid risk of burns. Then disconnect the appliance from
the mains power supply. This is important for all repairs, maintenance and servicing work.
Loosen the four Phillips screws at the top (Illustration 8 item 11 & 12), and completely remove only the two
screws at the rear (item 12).
Now lightly lift the upper enclosure front (Illustration 1 item 8) and remove the upper rear enclosure hood
(Illustration 1 item 7) toward the rear.
Danger! The cutting blade is very sharp! (Illustration 8 item 14)
Take off the blade holder by unscrewing the two Phillips screws (Illustration 8 item 18) from the blade handle.
The pressure rail (Illustration 8 item 15) is now visible. Now remove the right and the left sides of the
enclosure (they are attached by Velcro-type closures). Unscrew the right and the left studs on the end of the
pressure rail (Illustration 8 item 16), and pull the pressure rail out of the unit to the rear.
Replace the pressure rail, and install it by following the above steps in reverse order.

5 German DIN regulations
5.1 Width of sealed seams and clear space _________________________________
Width of sealed seams
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.
General:
•Do not select packages that are too small.
•Before sealing the packages, make sure to press them together to remove as much air as possible.
•If you wish to seal entire standard tray cassettes, the length of the film package should be at least twice
as long as the standard tray cassette (also see DIN 58953, Part 7). This also applies to the sterilization of
textiles in standard tray cassettes.

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 re-contaminated 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 re-contaminate 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).
