MAINTENANCE AND CLEANING
Maintenance:
If the Light Source does not operate properly when connected to a grounded receptacle, disconnect
the power cord and check the fuse (see below). Do not attempt to repair the unit if the lamp fails in
use. Turn off the unit and allow it to cool for at least 15 minutes, then try to restart the unit. If the lamp
still fails to illuminate, it may need to be replaced. If you still experience difficulties, return the unit to
Luxtec or an authorized distributor for evaluation.
To replace the fuse:
The fuses for the Light Source are located in the power entry module in the rear of the unit. Remove
the power cord from the unit. Using a small flat head screwdriver, open fuse access cover then pry out
the red plastic fuse holder from the power entry module. Check to see if the fuses are blown. If
necessary, replace the fuse(s) with a new one of the same rating (Fuse 3.15A, 250VAC, 5x20 mm,
Slo-Blo, IEC Standard, Luxtec part number 601919). After replacing fuse(s), push the red plastic fuse
holder back into the power entry module and snap access cover close. Plug the cord back into Light
Source and re-test the unit.
Cleaning:
Allow unit to cool for at least 15 minutes prior to cleaning.
The Light Source exterior can be cleaned and disinfected using 70% isopropyl alcohol. Unplug the
power cord before cleaning. Allow 5 minutes for alcohol to evaporate before reconnecting to power.
Use a vacuum cleaner and a soft brush to remove visible dust accumulation from fan and vent holes
whenever necessary and always when replacing the lamp.
