Maintenance; Exchanging Light Tubes - egger EL 1 plus N2 Bedienungsanleitung

4.7 Modifications/Repairs with Modeling Pastes
The LP/H modeling pastes can be universally used for
various modifications and repairs with all kinds of hard
UV-curing polymerizates or acrylates. These are available
in the colors trans-parent, beige, red and blue.
• First the part of the otoplastic that is to be processed
always has to be roughened with Corundum paper,
grit 180, (REF 40704).
• Then, clean and degrease the surface carefully by
using the provided hand-spray pump with a surface
cleaner.
• Directly apply the modeling paste out of the tube by
means of a modeling instrument (REF 31215) and
smooth the transitions to the ground .
• Then, depending on the coating thickness applied,
let it cure for about 2 – 4 minutes in the light unit
egger EL 1.
• After the polymerization of the surface, wipe off the
otoplastic by using a surface cleaner moisted cloth.
• If required, rework the otoplastic with a cutter and
prepare it for lacquering as de-scribed in 4.5/4.6.

5. Maintenance

!
Before each maintenance, the device must be un-
plugged from the mains supply.

5.1 Exchanging light tubes

On each exchanging of the tubes (6 x UVA REF 50103 as
well as 4 x Blue REF 50104) always ex-change them all.
Please be sure to always have some spare tubes in stock.
• Pull the tubes evenly backwards out of the socket.
Do not cant!
• Simply put the new tubes into the socket until they
are snapped in.
• The unit is now ready for action and can be connec-
ted to the mains supply.
• Used light tubes are hazardous waste and the legal
provisions for their disposal have to be adhered to.
5.2 Work performance of the halogen lamp
The work performance of the halogen lamp decisively
depends on the switching on frequency and the mains
voltage. The work performance averages approx. 1000
hours.
As the burning time of the light tube per polymerization is
pretty short, we recommend:
• exchanging the tubes each ½ year, if the unit is in a
daily use for about 8 hours
• exchanging the tubes each year, if the unit is not
used for more than 4 hours per day
Abrasion of the light tubes can be noticed on elongated
polymerization times and a dark discoloration along the
plug and socket area. Used light tubes are hazardous
waste. Please observe the current legal regulations.
