Before You Begin
The following will be needed for installing the UV system:
Tools
• Pipe cutter, hacksaw or other specialised tools required to cut into your existing
plumbing (e.g. if you have PEX piping)
• Soldering tools such as torch, flux, emery cloth and solder (only applicable if
working with copper pipes and connections)
• Wrench (for tightening fittings)
Other Materials
• Inlet/outlet connections
• Teflon™ 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 Microlene strongly recommends that appropriate
pretreatment equipment be installed (equipment required will depend on parameters
being treated):
Hardness:
<120ppm (120 mg/L) – if hardness level is 120ppm, 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):
<0.3 ppm (0.3 mg/L)
Manganese (Mn):
<0.05 ppm (0.05 mg/L)
Turbidity:
< 1 NTU
Tannins
(organics):
<0.1 ppm (0.1 mg/L)
UVT
(transmittance):
>85% (Please contact Microlene if water has a UVT that is less
than 80% for pre-treatment recommendations)
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 1 micron prior to a Microlene
UV disinfection system.
