Safety Instructions WARNING: To guard against injury, basic safety precautions should be observed, including the following: 1. Read and follow all safety instructions. 2. CAUTION - Always disconnect power before servicing. 3. DANGER - To avoid possible electric shock, special care should be taken since water is present near electrical equipment.
Routine Maintenance It is important that any water treatment system be properly maintained to ensure consistent water quality. The information provided on this page is of a general nature. See Cleaning, Disinfecting, and Routine Maintenance Procedure in this user guide. Cleaning: The inside of the system and the quartz sleeve should be cleaned bi-annually. Clean all parts (except the electronic parts) with soap and rinse them thoroughly with clean potable water.
1. The use of a bypass 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 bypass condition. In addition, during bypass, the water will NOT be disinfected until such time as the system is sanitized and returned to service. Please refer to the complete disinfection procedure as outlined on page 7 of this document.
Correct Installation Incorrect Installation IMPORTANT: For vertical installation, the inlet is at the bottom and the outlet is near the top of the disinfection chamber. For horizontal installation, pay careful attention to the diagram for flow direction. 3. Mount the system to the wall using the supplied clamps. Various connection methods can be used to connect the water source to the system, however union type connectors are recommended.
Clamps flow restrictor Countdown Timer Assembly Drip Loop Figure 1D Figure 1C 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.
OPERATION • Always disconnect power before performing any work on the disinfection system. • Regularly inspect your disinfection system to ensure that the power indicators are on and no alarms are present. • Replace the UV lamp annually (or biannually if seasonal home use) to ensure maximum disinfection. Operating & Maintenance Instructions CAUTION Prior to performing any work on the disinfection system, always disconnect the power supply first.
1. First remove the UV lamp by following steps as outlined in the “Lamp Replacement” section on page 8. 2. Shut off the upstream water supply that feeds water into the reactor chamber. 3. Shut off the downstream water supply. If your system does not have a separate downstream valve, simply open a downstream faucet to release any pressure that may be built-up in the system. 4. Unscrew the two aluminum nuts from the reactor chamber.
Troubleshooting PROBLEM 1. Pressure Drop CAUSE CORRECTION A. Sediment pre-filter clogged A. Replace filter cartridge with appropriate 5 micron cartridge. Note: check source water supply as fluctuations may occur in source pressure B. Flow regulator will result in pressure drop when approaching full flow. B. Flow regulator 2. High Bacteria Counts A. Quartz sleeve is stained or dirty B. Change in feed water quality C.
