Water Chemistry:
Water quality is extremely important for the optimum performance of your UV
disinfection 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 sleeve is 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
, electronic ballast 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 either horizontally or vertically at
the point-of-use or point-of-entry depending on the specific flow rate of the unit.
Note:
The ideal installation is vertical with the lamp connector on top. This is to
prevent water damage from occurring on the lamp pins and lamp connector.
• The ballast 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 1A).
• 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 (see page 6).
• 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.
• If treating the entire house, install the disinfection system before any branch lines.
• A 5 micron sediment filter must precede the disinfection system. Ideally, the
disinfection system should be the last treatment the water receives before it
reaches the faucet.
