The UV Dynamics UVD320E is a water disinfection system designed to provide clean water by utilizing ultraviolet (UV) light. This system is third-party validated using accepted bioassay techniques to ensure its performance in disinfecting water. It is certified against NSF/ANSI 61 for materials safety, NSF/ANSI 372 for lead-free compliance, and CSA-B483.1.
The primary function of the UVD320E is to disinfect water using UV radiation. Water flows through a chamber where it is exposed to UV light, which inactivates bacteria, viruses, and other microorganisms without the use of chemicals. The system is equipped with both visible and audio lamp failure alarms to alert users if the UV lamp is not functioning correctly. For optimal disinfection, the system requires source water that meets specific quality standards, including low turbidity, suspended solids, and iron content. The UV disinfection process occurs solely within the chamber and does not provide residual disinfection capability, meaning chemical disinfection of the entire plumbing system is necessary prior to initial use.
The UVD320E is designed for continuous operation and should be the final step in a water treatment system. It must be installed indoors in a protected area where temperatures remain between 4°C (40°F) and 29°C (85°F) to prevent condensation and optimize performance. The unit must be installed vertically with the lamp connector pointing upwards, and the water source should connect to the inlet port at the bottom. Reversing the flow direction can reduce disinfection performance.
The system includes a microprocessor-controlled UV power source with both audio and visual alarm indicators. During normal operation, a green "lamp-on" LED is illuminated. In case of a lamp failure or abnormal operating conditions, the alarm buzzer will sound, and the green LED will extinguish. If a solenoid valve is connected, it will terminate water flow upon lamp failure.
The power source also features an integral annual lamp change reminder timer. This timer runs for approximately one year, after which the lamp change reminder LED will flash, and the buzzer will sound, indicating a 28-day grace period. During this grace period, the buzzer can be silenced for seven-day intervals by pressing the timer button, up to a maximum of four times. After the grace period, the red timer LED will illuminate continuously, and the buzzer will sound, indicating that lamp replacement is due. The UV lamp continues to operate in this alarm mode, and the solenoid valve drive remains enabled. The remaining lamp life can be checked by pressing the timer button and counting the number of red timer LED flashes.
The system is designed to shut down if the AC input voltage falls outside operating limits. If a lamp failure alarm is active due to out-of-limit AC power, unplugging the unit for 15 seconds and reconnecting it will allow the unit to re-ignite and operate normally.
Regular maintenance is crucial for the UVD320E's optimal performance. The UV lamp needs to be replaced annually, regardless of its apparent condition, as its UV light penetration may fall below the prescribed safety level after approximately one year of continuous operation. When replacing the lamp, it is important to handle it by its ends or with soft gloves to avoid touching the lamp or quartz sleeve with bare fingers.
The quartz sleeve, which encases the UV lamp, also requires cleaning. It should be removed carefully, as it is fragile and can be easily chipped or broken. Cleaning the quartz sleeve with a vinegar solution or a readily available scale removal product (e.g., Limeaway, CLR) is recommended. If the "O" ring appears damaged during this process, it should be replaced.
After periods of not using the water supply for more than 2-3 days, it is recommended to open all faucets and flush plumbing lines for a minute or two. The unit must be protected from freezing, and all water should be drained if freezing temperatures are anticipated.
To reset the lamp change reminder timer, the UV power source must be disconnected from the AC supply for 15 seconds, then reconnected with the timer button depressed. A solid three-second beep will confirm a successful reset. This reset procedure is only possible when the timer is in the grace or lamp change alarm mode. Special instructions are provided with replacement lamps for resetting the timer prematurely due to early lamp failure.
Prior to initial service, all household plumbing lines should be chemically disinfected. This involves removing the 5-micron sediment filter cartridge, adding 250ml-500ml (1-2 cups) of standard 5.25% unscented chlorine bleach to the empty filter housing, and then reinstalling it. After allowing the bleach solution to sit for 30 minutes, the sediment filter cartridge should be reinstalled, and the system thoroughly flushed at all fixtures and appliances. If the hot water heater has been used with untreated hard water or water with excessive iron/manganese, a thorough flushing of the hot water tank is recommended to eliminate oxidized materials before introducing chlorine.
