Page 6: Water Chemistry
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. - Page 7 1. The above picture shows the installation of a typical disinfection system and the related components that may be used for the installation. The use of a by-pass assembly is recommended in case the system requires “off-line” maintenance. If this is the case, it must be noted that the system will require supplementary disinfection of the distribution system if any water is used during this by-pass condition.

Page 8: Disinfection Procedure
Disinfection Procedure: UV disinfection is a physical disinfection process and does not add any potentially harmful chemicals to the water. As UV does not provide a disinfection residual, it is imperative that the entire distribution system located after the UV be chemically disinfected to ensure that the water is free from any bacteriological contaminants. - Page 9 Operating & Maintenance Instructions: Caution: Prior to performing any work on the disinfection system, always disconnect the power supply first. UV LAMP REPLACEMENT: 1. To replace the lamp, there is NO need to disconnect the system from the water supply, nor to drain the water from the UV chamber. DO NOT USE WATER DURING THIS PROCEDURE. Lamp replacement is a quick and simple procedure requiring no special tools.
- Page 10 Please note that the lamp has an approximate life of one year. Although the lamp will continue to operate long past one year, the UV output continually decreases after one year and may no longer provide adequate disinfection. Use only Lancaster Water Treatment lamps to ensure proper operation and performance. RESET LAMP LIFE TIMER AFTER LAMP REPLACEMENT -...
