Water Chemistry:
Water quality is extremely important for the optimum performance of your UV
system. The following levels are recommended for installation:
•
Iron: < 0.3 ppm (0.3 mg/L)
•
Hardness*: < 7 gpg (120 mg/L)
•
Turbidity: < 1 NTU
•
Manganese: < 0.05 ppm (0.05 mg/L)
•
Tannins: < 0.1 ppm (0.1 mg/L)
•
UV Transmittance: > 75% (call factory for recommendations on
applications where UVT < 75%)
* Where total hardness is less than 7 gpg, the UV unit should operate efficiently
provided the quartz sleeves are cleaned periodically. If total hardness exceeds
7 gpg, the water should be softened. If your water chemistry contains levels in
excess of those mentioned above, proper pre-treatment is recommended to correct
these water problems prior to the installation of your UV disinfection system. These
water quality parameters can be tested by your local dealer, or by most private
analytical laboratories.
Proper pre-treatment is essential for the UV disinfection
system to operate as intended.
Installing your UV Disinfection System:
•
CAUTION
, power cord on ballast enclosure must be connected to a grounded
receptacle and the lamp connector ground wire connected to the stainless steel
reactor chamber.
• The disinfection system is designed to be mounted horizontally within the main
plumbing lines.
• The enclosure should be mounted either above or beside the reactor chamber.
Never mount vertically with AC connector at top of ballast to prevent moisture from
running down cordage and causing a potential fire hazard. Drip loops in all cordage
connected to ballast controller is highly recommended (see figure 1D).
• The complete water system, including any pressure or hot water tanks, must be
sterilized before start up by flushing with chlorine (household bleach) to destroy any
residual contamination.
• For safety purposes, the disinfection system should be connected to a ground fault
interrupt circuit.
• The disinfection system is intended for indoor use only, do not install disinfection
system where it may be exposed to the weather.
• Install the disinfection system on cold water line only.
• Install the disinfection system before any branch lines.
• 5 Micron filtration must precede the disinfection system. Ideally, the disinfection
system should be the last treatment the water receives before consumption.
