Maintenance

Before each maintenance, the device must be unplugged from the mains sup-
ply!

5.1 Exchanging light tubes

On each exchanging of the tubes (REF 50103) always exchange them all. Please mind to have
always some spare tubes in stock.
• Pull the tubes evenly backwards out of the socket. Do not cant!
• Just put the new tubes into the socket until they are snapped in.
• The unit is now ready for action and can be connected to the mains supply.
• Used light tubes are special waste and the legal provisions for their disposal have to
be adhered to.
5.2 Work performance of the halogen lamp
Its work performance decisively depends on the switching on frequency and the mains volt-
age. The work performance averages approx. 1000 hours.
As the burning time of the light tube per polymerization is pretty short, we recommend:
• to exchange the tubes each ½ year, if the unit is in a daily use for about 8 hours
• to exchange the tubes each year, if the unit is in use of not more than 4 hours per
day
Abrasion of the light tubes can be noticed on elongated polymerization times and a dark dis-
coloration along the plug and socket area. Used light tubes are hazardous waste. Please ob-
serve the current legal regulations.

5.3 Exchanging of reflecting foil

The polymerization performance of the light unit depends on the cleanliness of the light cham-
ber. The inbuilt reflectors (REF 51301) amplify the irradiation and always have to be clean, oth-
erwise, the polymerization times can change. Therefore, exchange in time the foils that are
fixed at the upper and the top side of the case.
