Thermostat
Control
-
This feature is
incorporated in all Aristo units. Thermo control maintains a
continuous ambient warmth around the lamp insuring peak brightness
at each start when operated through a timer or footswitch
Turn on your thermo switch or plug in your thermo cord and allow
your unit to warm up for about 5-10 minutes before making any
exposure.
To help speed up this warm-up period, the lamp
may be turned on at the same time for about 3 minutes, then shut
off. The unit is now ready to operate efficiently.
The thermo control should be left on continuously for the duration
of any day or working session.
Processing
Recommendations:
-
Negatives: Develop negatives 20-30% longer than recommended
for normal. This becomes the "Normal" negative for cold light
printing
-
Paper:
Expose paper so that full development time can be given. This will
produce prints of good contrast and maximum quality, maintaining a
full tonal range from the whitest highlights to the deepest blacks.
-
Maintenance and Care: Clean your unit periodically. With a
damp cloth wipe your lamp, reflector and diffusion plate of dust and
dirt which may accumulate. Keeping the until clean will help
maintain optimum evenness, speed and contrast.
With a minimum of care, your Aristo cold light unit will give you
years of faithful and trouble free service. All units are thoroughly
checked and tested before leaving the factory, and are guaranteed
for 90 days against defects in workmanship and materials.
When ordering replacement lamps, transformers or diffusion elements
for your unit, please specify your unit model number and color of
lamp desired, etc.
