Forward: The Delta UV Unit is designed for use in swimming pools, fountains, water features, waterfalls and
fish ponds. It is not designed for use in potable (drinking) water installations. Use of this product in
applications other than those indicated above will void your warranty and could be harmful to your health or the
health of others.
Introduction - How The Delta UV Unit Works: Within the Delta UV Unit (which we will refer to throughout
this manual as DELTA UV), a high intensity electrically operated Ultraviolet (UV) bulb is located inside the
unit’s wet chamber. This UV bulb gives off Ultraviolet light wave emissions when lit. The bulb’s operating
emission range is within the Ultraviolet light wave spectrum at 253.7 nm of wavelength. This wavelength is
such that when bacteria, protozoa, viruses, algae spores, or other single celled waterborne microorganisms in
the incoming water flow are exposed to the light waves of the UV bulb for a proper period of time, the DNA of
the microorganism is altered or disrupted and this controls and eradicates these unwanted contaminates and
renders them harmless. Your DELTA UV unit has been sized to produce these important UV rays in the same
intensity as is required for Class A potable drinking water, which is 30 microwatts/sec/cm2.
While you may see lesser competitive units of similar vessel size claiming to work on larger ponds or pools,
you will find that these units do not operate at the same high intensity as does the DELTA UV unit and are
unable to obtain the same level of disruption and eradication power as the DELTA UV unit. Rely on the flow
chart shown on page 3 for proper maximum disruption and eradication power unit selection for your
application. See Sect. A
Pond or pool water containing these unwanted contaminates enters the Delta UV wet chamber and is exposed to
the light rays generated by the UV bulb. The DELTA UV unit has been designed to allow for some turbidity in
the water, as turbidity will reduce the UV light wave transmission capability. Therefore, all DELTA UV units
are sized to allow for possible turbidity in the water and the reduction in the disruption and eradication power of
the UV bulb when it nears the end of its useful life. When the incoming water is exposed to the bulb for the
proper duration and intensity, the water exiting the unit is near drinking water biological quality.
