Another possibility is that the transient voltage surge suppressor (TVSS) is damaged, requiring a replacement. In some cases, the controller itself may be damaged, which means you'll need to replace the controller and use a TVSS.
What to do if Viqua E4-50+ Water System is operating but water tests reveal bacterial contamination?
If your Viqua Water System is operating but water tests show bacterial contamination, ensure that the UV system is the last piece of treatment equipment. Pathogens may be residing in the distribution lines post-UV, so ensure all distribution lines have been disinfected with chlorine. Also, remove any pipe dead-ends and flush with chlorine, as recontamination from pipe dead-ends may be the cause.
What to do if I see a leak detected from area of UV chamber of Viqua E4-50+?
If you notice a leak from the UV chamber area of your Viqua Water System, it could be due to condensation of moist air on the cold chamber. Try controlling the humidity or relocating the unit. Another cause might be a damaged, deteriorated, or incorrectly installed O-ring, so inspect and replace it if deteriorated. Also, the lamp/sleeve assembly might not be properly installed; tighten the assembly hand-tight.
How to fix a leak at the inlet or outlet of my Viqua E4-50+?
If you have a leak at the inlet or outlet of your Viqua Water System, it's likely due to leaking threaded pipe fittings. You should clean the threads, reseal them with Teflon tape, and then retighten.
What to do if I see a leak detected at sensor of Viqua E4-50+ Water System?
If you detect a leak at the sensor of your Viqua Water System, the UV sensor O-rings may be damaged, deteriorated, or incorrectly installed. Inspect the O-rings and replace them if they show signs of deterioration.

This document is an owner's manual for a VIQUA ultraviolet (UV) water disinfection system, designed to provide safe drinking water by eliminating microbiological contaminants. The system utilizes advanced UV technology for effective water treatment.
The VIQUA UV water disinfection system is designed to treat potable water by exposing it to ultraviolet light, which inactivates bacteria, viruses, and other microorganisms. This physical disinfection process does not add chemicals to the water, making it a safe and environmentally friendly option. The system is intended for permanent connection to water lines and can be installed either at the point-of-use or point-of-entry, depending on the required flow rate.
The core of the system is the UV lamp, which emits UV-C radiation. This lamp is housed within a UV chamber, through which water flows. A quartz sleeve encases the UV lamp, protecting it from direct contact with water while allowing UV light to pass through. The system includes a controller that powers and manages the UV lamp and other components. This controller provides a human interface, displaying system status information and allowing control inputs, such as muting audible alarms. For safety, the power source for the controller must be connected to a Ground Fault Circuit Interrupter (GFCI) receptacle.
Some models include a UV sensor, which monitors the UV output to ensure that a proper UV dose (exposure) is being provided for effective disinfection. An optional solenoid valve kit can be integrated, which allows the water supply to be shut off automatically if proper disinfection cannot be assured, for example, during a major alarm condition. This feature requires a junction box for connection. Additionally, a CoolTouch™ valve may be included, which drains water from the chamber that has been warmed by the lamp during periods of no flow, preventing potential scalding. A flow restrictor is also an optional component that ensures water flows over the maximum NSF certified flow rate, maintaining an adequate UV dose.
The controller features a display screen that shows various information, including lamp life in days, product information (including replacement part numbers), product support contact details, and UV level status. It also indicates active alarms. Two pushbuttons on the controller allow users to scroll through information, mute alarms (including a 24-hour mute option), cancel operations, reset the lamp timer, select options, and close screens.
The system is designed to operate continuously, providing ongoing protection against microbiological contaminants. However, it does not provide a disinfection residual, meaning that the entire distribution system after the UV unit must be chemically disinfected to ensure it is free from bacteriological contaminants. This disinfection procedure is crucial immediately after installation and whenever the UV unit is shut down for service, loses power, or becomes inoperative for any reason.
The system is designed for ease of use with several features to guide the user. The controller's display provides clear status updates and alerts. For instance, it indicates when the UV lamp is nearing the end of its operating life (End of Lamp Life Warning) or has reached it (End of Lamp Life Alarm). These alarms can be temporarily silenced for 7 days using the mute button, and the End of Life (EOL) alarm can be deferred up to 4 times.
The controller also guides the user through troubleshooting steps for various alarms, such as "Lamp Failure," "Low UV Failure," "Controller Failure," and "Sensor Connection Failure." For each alarm, the display provides a sequence of actions to take, such as checking connections, replacing components, or contacting support. The "Scroll" button advances through these troubleshooting guides, and the "Close" button returns to the status screen.
For replacement controllers, a "Model Selection" screen appears during startup, allowing users to select their specific system model. This ensures that the correct replacement part numbers are displayed in the "Product Information" screen. The controller also includes a "Product Registration" screen, reminding users to register their product for updates and lamp replacement reminders.
The system incorporates a "Dry Contact Connection" feature, which allows connection to a remote device like a solenoid valve or a remote alarm indicator. This connection provides information on major alarms, including "Low UV Failure," "Controller Failure," "Lamp Failure," and "UV Sensor Failure," enabling automated responses or remote monitoring.
Regular maintenance is crucial for the optimal performance and longevity of the VIQUA UV system. The manual outlines several key maintenance procedures:
UV Lamp Replacement: The UV lamp has an effective life of approximately 9000 hours (about one year) and must be replaced annually to ensure continuous disinfection. The replacement process is designed to be quick and simple, requiring no special tools. It involves disconnecting power, shutting off water, removing the lamp connector, pulling out the old lamp, inserting a new lamp, and reconnecting. After replacement, the lamp timer on the controller must be reset. The manual emphasizes using only genuine VIQUA replacement lamps to avoid damaging the control module and to ensure safety and performance certifications are maintained.
Quartz Sleeve Cleaning and Replacement: Minerals in the water can form a coating on the quartz sleeve, which reduces the amount of UV light reaching the water and impairs disinfection performance. The manual recommends periodic cleaning of the quartz sleeve. This involves shutting off the water supply, draining lines, depressurizing the unit, removing the UV lamp, unscrewing the sleeve bolt, and carefully removing the quartz sleeve. The sleeve should then be cleaned with a cloth soaked in CLR, vinegar, or a mild acid, followed by a water rinse. If the sleeve cannot be cleaned completely, or if it is scratched or cracked, it must be replaced. After cleaning or replacement, the quartz sleeve is reinstalled, and the UV sensor (if present) is also cleaned.
Disinfection Procedure: After installation, or any service that involves shutting down the UV unit or bypassing it, the entire plumbing system downstream of the UV unit must be chemically disinfected. This procedure involves shutting off the water supply, closing faucets, releasing pressure from cartridges, removing sump housings, pouring household bleach solution into the sump housings, reinstalling sumps, turning on water supply to fill the chamber, and then flushing all water outlets until the smell of bleach is detected. The bleach is allowed to settle in the lines for 30 minutes, after which cartridges are reinstalled, and all water outlets are flushed until the bleach smell is gone.
Pre-treatment Maintenance: The manual stresses the importance of water quality for the UV system's performance. It recommends installing a 5-micron (nominal) sediment filter before the UV system and after any water softening equipment. If water chemistry parameters (such as iron, hardness, turbidity, manganese, or tannins) exceed recommended levels, proper pre-treatment is essential. Maintenance of these pre-treatment systems is implied as part of overall system care.
The manual also provides safety precautions, including warnings about electrical shock, UV radiation exposure, and hot water. It advises against operating the system with a damaged cord or plug, or if it is malfunctioning. It also specifies that the system should not be installed where it will be exposed to weather or freezing temperatures.
