•
Soldering tools (torch, flux, emery cloth and solder)
•
Wrench (for tightening fittings)
Other Materials
•
Inlet/outlet connections
•
Thread seal tape
Water Quality Parameters
UV disinfection is extremely effective against microorganisms but only if the UV light can
pass through the water it needs to treat. This means that the quality of your water is very
important in order to ensure complete disinfection.
Treated water should be tested for at the least the parameters listed below. If the water
exceeds the listed parameters Puretec strongly recommends that appropriate pretreatment
equipment be installed (equipment required will depend on parameters being treated):
Where the water being treated contains unusually high levels of dissolved solids particularly
hard water, iron, manganese or biological organisms, a deposit build up on the quartz sleeve
may occur over time. Maximum recommended parameters are as follows:
Hardness:
less than 7 gpg (120 mg/L) – if hardness level is 7 gpg or slightly
below, the quartz sleeve must be cleaned periodically in order to
ensure efficient UV penetration; if above the water must be softened.
Iron (Fe):
less than 0.3 ppm (0.3 mg/L)
Manganese (Mn):
less than 0.05 ppm (0.05 mg/L)
Turbidity:
less than 1 NTU
Tannins (organics):
less than 0.1 ppm (0.1 mg/L)
UVT (transmittance):
more than 85% (Please contact Puretec if water has a UVT that is
less than 80% for pre-treatment recommendations).
Application warning: minimum water characteristics must be met before installation
of Radfire™ to ensure proper operation and continuous protection.
You can have your water tested at a private analytical laboratory or by your local dealer. It
is always recommended to install pre-filtration of at least 5 microns prior to a Puretec UV
disinfection system. Not designed for brackish or sea water.
