Due to fog residue, smoke and dust, cleaning the internal and external optical
lenses and mirror should be carried out periodically to optimize light output.
Cleaning frequency depends on the environment in which the fixture 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.
1. Use normal glass cleaner and a soft cloth to wipe down the outside
casing.
2. Use a brush to wipe down the cooling vents and fan grill.
3. Clean the external optics with glass cleaner and a soft cloth every 20 days.
4. Clean the internal optics with glass cleaner and a soft cloth every 30-60
days.
5. Always be sure to dry all parts completely before plugging the unit back in.

or on PCB of the fixture or the previous one.
