Fixture Cleaning: Due to fog residue, smoke, and dust clean-
ing the internal and external optical lenses and mirror should be
carried out periodically to optimize light output. Cleaning fre-
quency depends on the environment in which the fixture oper-
ates (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 and mirror 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.
