Post-Curing With Gas; Lacquering With Lp/W Lacquer - egger EL 1 plus N2 Bedienungsanleitung

egger EL 1 plus N

4.4 Post-curing with gas

The following conditions must be fulfilled:
• The plastic box must be situated on the working table
of the unit.
• The unit and the nitrogen cylinder are connected
through the gas connecting tube.
• The mains plug is plugged.
• Switch on the unit (main switch).
• Insert the curing material into the plastic box.
• The curing materials must not touch each other!
• Insert shells and ventings into the plastic box with the
opening facing up.
• Close the plastic box with the cover.
• Close the unit with the safety cover.
• The gas switch must be positioned at "ON".
• Adjust the required polymerization time by using the
turning knob (+/-).
• Press the "START/STOP" button.
• After the polymerization, the device switches off
automatically and a signal tone can be heard.
4.5 Lacquering with LP/H lacquer and/or LP/H lac-
quer antibac
By using the LP/H lacquer (REF 3062ff) or LP/H lacquer
antibac, you can protect hard earmolds due to an anti-
bacterial coating with high gloss effect
• First the part of the earmold that is to be processed
always has to be roughened with Corundum paper,
grit 180, (REF 40704).
• Then, fix the BTE earmold onto a piece of nylon tube
(REF 97200) and also fix the lac-quering holder. With
an ITE earmold, the special Erkogum (REF 30911)
can be fixed to the opened battery valve.

• Then, clean and degrease the surface carefully by
using the provided hand-spray pump with a surface
cleaner (REF 316ff).
• Apply the lacquer evenly. Alternatively, you can also
immerse the earmold (but no ITE device with an in-
built electronic or face-plates!) into a dipping jar filled
with lacquer (REF 31400 or 31401). Please mind to
shake off lacquer remnants.
• Then, let the lacquer cure in the egger light unit for
about 2 – 4 minutes. The earmold can then immedi-
ately be inserted.

4.6 Lacquering with LP/W lacquer

For the surface finish the light-curing soft earmolds
(made of LP/W) are always lacquered with LP/W lac-
quer (REF 307ff). Furthermore, all presently known hard
acrylate-based otoplastic materials can be coated with
LP/W lacquer to improve the fitting of the earmold ("non-
skid coating").
• First the part of the otoplastic that is to be processed
always has to be roughened with Corundum paper,
grit 180, (REF 40704).
• Then, fix the BTE earmold onto a piece of nylon tube
(REF 97200) and also fix the lacquering holder. With
an ITE earmold, the special Erkogum can be fixed at
the opened battery valve.
• Then, clean and degrease the surface carefully by
using the provided hand-spray pump with a surface
cleaner (REF 316ff).
• Apply evenly the lacquer and cure it for 4-5 minutes
in the light unit.
• After the polymerization, the otoplastic is post-cured
in the egger light unit EL 1 plus N
minutes. This is necessary to remove the inhibition
layer (sticky surface).
