MAINTENANCE
To ensure optimum and uninterrupted performance from the Pro 1220 it is important to keep it
clean at all times. Dusty lenses will reduce the brightness and blocked fans may cause overheating,
thus causing the thermostat to cut off the lamp intermittently. Thanks to the modular construction of
the Pro 1220, maintenance can be done easily and does not require any special tools. Simply
remove the module(s), that you wish to clean, as described in the previous section.
CLEANING THE OPTICAL PATH
You should be very careful when cleaning the color filters, lenses and the reflector. The colored
surface on the filters is achieved by means of special coatings and even small scratches may be vis-
ible. Use only a clean, soft and lint-free cloth like the ones used for cleaning camera lenses. You
may need to wet the cloth in a passive glass cleaning liquid if the filters or lenses are greasy. It may
also be necessary to clean the gobos and the iris and special care should be taken not to damage
these fragile items.
CLEANING THE FANS
To ensure proper cooling of the fixture it is important that the fans are free from dust. Clean the fans
if the air flow seams to be reduced.
CLEANING THE OPTICAL SENSORS
Optical sensors have been placed on the color and the rotating gobo modules. Clean those sensors
of dust to ensure reliable and accurate indexing.
