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: <0.1ppm (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:
• C
AUTION
, electronic ballast must be connected to a grounded receptacle. A ground fault protected circuit (GFCI) is
recommended.
• 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 connector and lamp pins. Leave space at least equal to the
overall length of the disinfection system to allow clearance for the removal and replacement of the lamp and/or quartz
sleeve.
• The electronic ballast should be mounted either above or beside the stainless steel UV reactor chamber. Never mount
ballast 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 is highly recommended.
• 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 8).
• The disinfection system is intended for indoor use only. Do not install disinfection system where it may be exposed to the
weather. Protect system from freezing temperature.
• Refer to specifications page for ambient conditions and maximum operating pressure.
• 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.
