WELCOME
The ULTRA UV Unit is designed for use in swimming pools, spas,
fountains, water features, waterfalls, fish ponds and the like. 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.
gENERAL PRODUCT INFORMATION
Water circulates through the ULTRA UV chamber and around the quartz
tube where the UV-C lamps (1 to 4 lamps depending on the model)
are housed. The UV-C lamp emits a light wave spectrum (253.7 nm
wavelength) to immediately inactivate 99.9% of micro-organisms such as
Crypto, Giardia, other single celled waterborne microorganisms and algae
which are resistant to chlorine. This provides a cleaner, clearer swimming
environment with zero harmful by-products and dramatically reduces
the amount of chlorine needed to maintain an adequate level of residual
sanitizer. The ULTRA 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 30,000 micro watts/cm2. (30 mJ) Confirm the size unit
your application needs by using the sizing charts on page 2 and 3, to
obtain the proper maximum system killing power.
CAUTION: DO NOT USE THIS UNIT FOR
POTABLE (DRINKINg) WATER SANITATION.
ULTRA UV SYSTEM SIzINg
In order to ensure that your ULTRA UV unit functions with the proper water
exposure time to achieve the desired water sanitation, it is important to
provide the proper water flow rate through the ULTRA UV unit. If water
passes through the unit too quickly, the microorganism’s exposure time to
the UV lamp(s) produced rays will not be sufficient to obtain the desired
rate of sanitation. The water flow rate through the UV unit is governed
by the piping of your water vessel and the size and output of your
circulation pump. Consideration to the application for the UV unit must be
determined. Fish ponds, as an example, have different requirements than
swimming pools, spas, water features, fountains, or waterfalls, as noted
elsewhere in this manual
POND SIzINg CONSIDERATIONS
Most fish pond experts agree that there is no simple or set formula for the
sizing of circulation pumps and UV systems for fish ponds. The best advice
is to consult a fish pond expert to determine what the flow rate for your pond
should be, and use the appropriate sized ULTRA UV for that flow rate.
