Cleaning
Fixture Cleaning:
Due to fog residue, smoke, and dust cleaning the
internal and external optical lenses must be carried out periodically to
optimize light output.
1. Use normal glass cleaner and a soft cloth to wipe down the
outside casing.
2. Clean the external optics with glass cleaner and a soft cloth every
20 days.
3. Clean the internal optics with glass cleaner and a soft cloth
every 30-60 days.
4. Always be sure to dry all parts completely before plugging
the unit back in.
Cleaning frequency depends on the environment in which the fix-
ture operates (I.e. smoke, fog residue, dust, dew). In heavy club use
we recommend cleaning on a monthly basis. Periodic cleaning will
ensure longevity, and crisp output.

Fuse Replacement
Locate and remove the unit’s power cord. Once the cord has been
removed locate the fuse holder located inside the power socket. Insert
a flat-head screw driver into the power socket and gently pry out the
fuse holder. Remove the bad fuse and replace with a new one. The
fuse holder has a built-in socket for a spare fuse be sure not to con-
fuse the spare fuse with active fuse.
