Maintenance
Before each maintenance, the device must be unplugged from the mains
supply!
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 straight backwards out of the socket. Do not cant!
•
Simply put the new tubes into the socket until they are snapped into place.
•
The unit is now again ready for operation and can be connected to the mains sup-
ply.
•
Spent light tubes are special waste and the legal provisions for their disposal must to
be adhered to.
5.2. Work performance of the light tubes
Its work performance 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 very short, we recommend:
•
exchanging the tubes every ½ year, if the unit is in daily use of approx. 8 hours
•
exchanging the tubes every year, if the unit is in use for not more than 4 hours per day
Abrasion of the light tubes can be noticed on elongated polymerization times and/or a dark
discoloration along the plug and socket area.
5.3 Exchanging of reflecting foil
The polymerization performance of the light-curing unit depends on the cleanliness of the light
chamber. The built-in reflectors (REF 51301) amplify the irradiation and always have to be
clean, otherwise, the polymerization times can change. Therefore, exchange in time the foils
that are fixed on the upper and the top side of the casing.
