manuals supplied with the equipment.
platemaker is shock mounted and ready for operation when
the power cord is inserted into the applicable polarized wall
receptacle. The flip-top vacuum printer frame is used to hold
film securely against a sensitized plate while the image on the
film is being printed on the plate. The vacuum for the flip-top
printing frame is developed by a vacuum pump.
Due to installation requirements, the blower
unit, used to ventilate the machine, which is
normally mounted on the external side of the rear panel, is
now located within the lower compartment. To gain access to
the mercury vapor lamp mechanism, which is located directly
above lower compartment, position flip-top frame in a vertical
position to expose the lamp reflector. Remove the glass
shield within the unit to expose the lamp mechanism for
cleaning and replacement of vapor lamp tube.
The mercury vapor lamp should not
be operated above 110 of rated
voltage. Such operation increases
pressure within the lamp which could
cause a tendency to shatter with
subsequent ultraviolet output causing
skin and eye irritation.
