Ultra Uv2 System Sizing; Pool, Spa, Fountain, Water Feature And Water Fall Sizing Chart - Paramount Fitness Ultra UV2 Instruction & Operation Manual

GENERAL PRODUCT INFORMATION
Water circulates through the Ultra UV2 chamber and around the quartz tube where the UV-C lamp(s) (1
to 3 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 UV2 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 3, to obtain the proper maximum system killing power.
Please note the minimum and maximum flow rates for each Ultra UV2 lamp configurations.
CAUTION

ULTRA UV2 SYSTEM SIZING

In order to ensure that your Ultra UV2 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 UV2 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. Please note that the minimum
posted flow rate must be met or exceeded to ensure proper system performance. 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.
