UVP R-52G - Manual (Page 2)

Introduction
Your new R-52G lamp represents the highest achievement in ultraviolet lamp
history. The result of extensive research and craftsmanship, this lamp will give you
years of trouble-free service. All R-52G lamps are constructed of hand-contoured,
rugged Cycolac ® plastic and use a shortwave, 254nm lamp grid.
Ultraviolet Light
Ultraviolet energy cannot be detected by the human eye. Only a blue-hued light
will be visible through the filter of the lamp. This is due to the emission of visible
light from the lamp grid. The integrated filter eliminates most of this visible light
interference and also reduces solarization for prolonged filter life.
Shortwave ultraviolet energy is shorter in wavelength than visible violet light, and
can be classified as follows:
Shortwave:
The ultraviolet energy farthest from visible light, shorter than rays in
sunlight, and primarily noted for its ability to fluoresce minerals for
chemical analysis. It is also noted for its germicidal effects.
Operating Instructions
Plug your lamp into a standard AC outlet. Push the black switch on the housing up
to the ON position. To turn off the light, press the switch down to the OFF position.
For sterilization and bacterial destruction, the filter plate can be removed for
additional intensity.
Lamp Housing
To remove the lamp housing from the transformer handle, grasp the top of the
transformer with the right hand. Then, grasp the lamp housing with the left hand
fingers over the nameplate and thumb just in front of the filter frame (under side of
lamp housing). Twist the lamp up and out to remove.
Filter
Shortwave Mineralight lamp filters have a rated average life of 1,000 hours. When
the ultraviolet intensity on the shortwave lamp decreases considerably, a new filter
is needed. To prolong the life of the shortwave filter, make sure the lamp is turned
off when not in use.
Frame Removal
To remove the filter frame for maximum photochemical reactions
(phosphorescence and rare earths), slide a coin or screwdriver into the slot under
the nylon button and twist. This will raise the button approximately 1/4 inch and
snap twice. This will disengage the filter frame from the lamp housing. Lift up the
frame and pull out from the lamp housing.
To replace the filter frame, slide the large part of the frame into the lower end of
the lamp housing. Press the frame into position and snap the nylon button inward
to the locking position.
To replace the filter glass, remove the old filter frame, as described above, and
insert the new filter frame into place.
WARNING
Do not look into a lighted shortwave Mineralight® lamp as it can
quickly burn your eyes and skin. Always hold Mineralight lamps so that
the light beams are away from you.
Eye and face protection is essential for anyone working with ultraviolet
sources, as these can cause burning. See Page 4 for protective
equipment ordering information.
