Although your Echo Water UV system has been manufactured to the highest safety standards, extreme care must be followed when operating and/or maintaining your system.
-
Power Disconnection: Always disconnect the power cord from the electrical outlet when servicing this equipment.
-
UV Exposure: As the energy emitted by the UV lamp can be harmful to your eyes and skin, NEVER look directly at an illuminated UV lamp without adequate eye protection, and always protect your skin from direct exposure to the UV light.
-
Genuine Parts: To ensure the system provides adequate disinfection, ALWAYS replace any component (lamp and sleeve) with a genuine Echo Water replacement part.
-
Damaged Components: Do not operate the unit if it has any damaged or missing components.
-
Electrical Safety: To avoid the risk of electrical shock, use only with a properly grounded electrical outlet.
-
Comfort and Expertise: Never perform any maintenance to the system unless you are comfortable doing so. Contact Echo Water for service instructions if required.
-
Intended Use: Do not use this system for any purpose other than what it was intended for. Misuse of this system could potentially cause harm to the user.
-
Installation Location: Your system is intended to be installed indoors and away from leaking plumbing. DO NOT plug the unit in if the system or any of the components are wet.
-
GFCI Installation: The disinfection system should be directly installed into a ground fault circuit interrupter (GFCI). If the use of an extension cord is required, the cord must be manufactured with a minimum of 16-gauge wire, and care should be taken to avoid potential tripping hazards.
-
Professional Installation: We recommend that a licensed plumber or certified technician perform the installation.
Before You Begin
Before starting the installation, ensure you have the following tools and materials:
Tools
-
Pipe Cutter, Hacksaw, or Specialized Tools: For cutting into your existing plumbing (e.g., if you have PEX piping).
-
Soldering Tools: Including a torch, flux, emery cloth, and solder.
-
Wrench: For tightening fittings.
Other Materials
-
Inlet/Outlet Connections: To connect the system to your plumbing.
-
Teflon™ Tape: For sealing threaded connections.
Water Quality Parameters:
UV disinfection is highly effective at killing microorganisms, but it requires the UV light to pass through the water effectively. Therefore, water quality plays a crucial role in ensuring complete disinfection.
To guarantee optimal performance, it is essential to have your water tested for at least the following parameters. If your water exceeds these limits, Echo Water recommends installing the appropriate pretreatment equipment (based on the specific parameters to be treated):
-
Hardness: <7 gpg (120 mg/L)
-
If hardness is at or slightly below 7 gpg, the quartz sleeve must be cleaned periodically for efficient UV penetration.
-
If hardness is above 7 gpg, water softening is recommended.
-
-
Iron (Fe): <0.3 ppm (0.3 mg/L)
-
Manganese (Mn): <0.05 ppm (0.05 mg/L)
-
Turbidity: <1 NTU
-
Tannins (Organics): <0.1 ppm (0.1 mg/L)
-
UVT (Ultraviolet Transmittance): >85%
-
For water with UVT less than 80%, please contact Echo Water for pre-treatment recommendations.
-
Water testing can be done through a private analytical laboratory or by your local dealer. It is highly recommended to install pre-filtration of at least 5 microns before the Echo Water UV disinfection system for the best results.
Assembly
Step 1: Unpack the System
Unpack the system and verify that all components are included. Your system is shipped with the following components:
Echo Water UV systems are rated for a specific flow rate based on water quality parameters. The equipment is designed to deliver the correct dose as long as all parameters are followed. It’s important to note that while the system’s flow rate can vary, this will directly affect the disinfection dose. A lower flow rate will increase the dose, but a higher flow rate may decrease the dose, compromising microorganism inactivation.
It’s essential to determine your water system's maximum flow rate. If unsure, you can measure it by filling a 1-gallon bucket with water and timing how long it takes to fill it. This will give you the maximum flow rate for your home. Always choose an Echo Water system that suits this flow rate.
Important Note: It’s generally better to oversize your system rather than undersize it. For example, if your pump delivers 8 gpm, it is recommended to install an Echo Water 10 gpm system, as there may be times when your home uses water at the pump’s maximum capacity.
Location
Step 1: Choose a Suitable Location
Find a location to mount the UV reactor and controller. Ensure that the controller is located within 5 feet of a Ground Fault Circuit Interrupter (GFCI), and that there is easy access to the main cold water line, prior to any branch lines and before the hot water heater. If you have other water treatment equipment (e.g., softeners, filters), make sure the UV system is the last piece of equipment in the treatment process.
Note: All Echo Water UV disinfection systems are designed for indoor use only and should not be exposed to the elements.
Step 2: Mounting the UV Reactor and Controller
The system includes mounting hardware for both the UV reactor and the controller. If the supplied fasteners are not suitable for your structure, please ensure you use the correct fasteners.
Step 3: Ensure Adequate Space for Lamp Removal
To facilitate lamp removal, ensure there is enough space at the lamp connector end to safely remove the UV lamp and/or quartz sleeve. A space equal to the length of the unit will suffice (see Figure 1).
Installation
Step 1: Installation Location
The UV disinfection system should always be the final piece of treatment before the water branches off to the hot and cold water lines if used as Point of Entry (POE) (see Figure 2). For Point of Use (POU), the system should be installed as the last treatment before the faucet.
Step 2: Install a 5-Micron Filter
Echo Water strongly recommends installing a 5-micron filter before the UV system as a final polishing step before disinfection.
Step 3: Installing the Reactor
The reactor can be installed horizontally or vertically using the provided clamps. However, vertical installation is preferred, with the inlet at the bottom (lamp connection at the top) as this facilitates air purging from the system.
Step 4: Use a Flow Restrictor
If the water supply flow rate is unknown, it’s recommended to use a flow restrictor to ensure the flow does not exceed the rated capacity of your Echo Water system, thus ensuring the UV dose is maintained. The flow restrictor should be installed on the outlet port of the reactor.
Step 5: Licensed Plumber Installation Recommendation
Echo Water strongly recommends having a licensed plumber connect the UV reactor to the water supply. In some locations, this may be a requirement. If you are installing the system yourself, ensure you have all the necessary tools and fittings to complete the installation.
Step 6: Plumbing Installation Procedure
While there are various installation methods, this manual outlines a recommended procedure using copper plumbing and standard soldering techniques. Echo Water recommends using unions, a by-pass assembly, and shut-off valves to allow easy isolation and removal of the UV reactor if needed. This method provides maximum convenience but requires additional components and installation time. Refer to Figure 3 for the recommended installation.
Step 7: Preparing and Cutting the Cold Water Line
Before cutting into the cold water line, measure and cut all piping as per the recommended layout. Once the components are prepared, begin by installing the female adapters onto the ports of the reactor. To ensure a proper seal, apply Teflon™ tape to all threaded connections.
Step 8: Soldering and Connecting the System
Next, solder all the components together, including ball valves, unions, and finally connect the by-pass assembly to the cold water feed line (water in and water out).
Step 9: Installing the Quartz Sleeve
Carefully remove the quartz sleeve from its packaging, ensuring that you do not touch the length of the sleeve. It is highly recommended to wear cotton gloves (not included) for this step, as oils from your hands can leave residue that may block the UV light from reaching the water. In the package, you will find a lubricated O-ring. Place this O-ring over the open end of the sleeve, as shown in Figure 4.
Step 10: Inserting the Quartz Sleeve
Gently slide the quartz sleeve into the reactor until you feel it hit the opposite end of the reactor. Slightly push the sleeve to ensure it locks into the spring inside the reactor. Confirm that the O-ring is properly seated against the reactor. Assemble the provided gland nut onto the threaded end of the reactor and tighten. The gland nut has a positive stop to avoid over-tightening, so hand tighten ONLY.
Next, install the provided stainless steel compression spring inside the quartz sleeve. This spring should simply rest at the bottom of the sleeve and align the lamp and lamp connector properly. Important Note: Do not install the UV lamp inside the quartz sleeve without the spring in place.
Step 11: Installing the UV Sensor (if applicable)
If your system includes a UV sensor (Echo Water 6.0), it will be packaged separately in a plastic bag. Carefully remove the sensor from its packaging and insert it into the UV sensor port (first remove the protective cap from the UV reactor). The sensor can only be installed in one direction. Ensure the flat portion of the UV sensor aligns with the half metal lip on the sensor port (the flat portion should face the lamp connection end, as shown in Figure 5).
Ensure the sensor is fully seated in the port, then tighten the sensor nut by turning it clockwise. Important Note: Do not over-tighten the nut, as this could damage the Teflon sensor body. Plug the male connector into the IEP port on the right side of the controller (refer to Figure 6). Make sure the controller is not plugged in before connecting the sensor, as the sensor must be attached before power is applied to the controller.
Step 12: Leak Testing and Water Flow
With all plumbing connections complete, the reactor is now ready for water flow. Slowly turn on the water supply and carefully inspect all fittings and seals for potential leaks. Verify that the by-pass valves function correctly and that water is flowing through the UV reactor.
Note: The most common source of leaks is the O-ring failing to create a proper seal. If a leak occurs at the O-ring:
-
Turn off the water and drain the reactor.
-
Remove the O-ring, dry it thoroughly, and reapply a thin layer of silicone grease.
-
Reseat the O-ring carefully, ensuring it’s properly positioned against the reactor.
-
Recheck for leaks once the system is refilled.
Step 13: Mounting the Controller
Mount the controller on the wall above or beside the reactor, never below, to prevent any moisture from reaching electrical connections (see Figure 2). The controller must be mounted vertically to ensure proper operation and cooling.
For safety, the controller must be plugged into a ground fault circuit interrupter (GFCI) outlet. This protects against electrical hazards in the event of moisture exposure.
Step 14: Installing the UV Lamp
Carefully remove the UV lamp from its packaging, avoiding contact with the quartz surface. The use of cotton gloves is strongly recommended to prevent oils from your hands depositing on the lamp, which can reduce UV effectiveness.
Always hold the lamp by its ceramic ends.
Before inserting the lamp into the reactor:
-
Connect the lamp to the lamp connector as illustrated in Figure 7.
-
Ensure the connection is secure and properly aligned.
⚠️ Do not insert the lamp into the quartz sleeve until it is connected to the lamp connector. Proceed to the next step for final insertion and system power-up.
Step 15: Inserting the UV Lamp
Once the lamp is securely connected to the lamp connector (as described in Step 14), carefully insert the lamp into the reactor, sliding it gently into the quartz sleeve.
⚠️ Do not drop or force the lamp into the sleeve—this may damage both the lamp and the quartz sleeve.
With the lamp fully inserted, affix the lamp connector into the gland nut by:
-
Inserting the connector into the nut
-
Turning it approximately ¼ turn clockwise until it locks securely in place
Ensure a snug fit without over-tightening.
Step 16: Connecting the Ground Screw
To ensure proper electrical safety and grounding continuity:
-
Locate the captive ground screw included with the system
-
Attach it securely to the ground lug located on the UV reactor housing
This step is critical for preventing electrical hazards and ensuring the system operates within safety standards.
Step 17: Powering the System
Your UV system is now fully assembled and connected.
-
Plug the controller into a GFCI-protected electrical outlet
-
Do not allow water to flow through the system yet
Before running water, refer to the “System Disinfection” section of this manual.
This section outlines the important steps required to properly sanitize your plumbing system and ensure that only disinfected water passes through the UV chamber. Skipping this step could allow microbial contamination to persist in your plumbing system.
System Disinfection
Once the Echo Water UV system is installed, it's important to disinfect the entire plumbing system to ensure safe, microorganism-free water throughout your home or facility.
Disinfection Procedure
Step 1:
Inspect the plumbing system to ensure there are no “dead ends,” as these areas can harbor bacteria. Confirm that the UV system is powered and operational before proceeding.
Step 2:
Remove the cartridge from the filter sump. Fill the sump with 1–2 cups of household bleach (5.25% chlorine). Reinstall the sump and slowly turn on the water supply.
Step 3:
Go to each water outlet in the home or facility—including outdoor taps—and run water until chlorine can be smelled. This includes:
-
Faucets
-
Showerheads
-
Toilets
-
Dishwashers
-
Washing machines
-
Refrigerators, etc.
Once chlorine is present at all outlets, shut off all faucets and allow the chlorine to remain in the lines for at least 30 minutes.
Step 4:
After 30 minutes, reinstall the filter cartridge and open all faucets again. Flush the lines until chlorine is no longer detected by smell.
Your plumbing system is now disinfected, and your Echo Water UV system is ready to inactivate any microorganisms entering your water supply.
⚠️ IMPORTANT: Repeat this procedure any time the UV system has been turned off for service, power failure, or has been inoperative, to prevent possible contamination.
Cleaning the Quartz Sleeve
Quartz sleeve cleaning frequency depends on water quality. Clean at least once annually. Follow these steps:
Quartz Sleeve Cleaning Procedure
Step 1:
Shut off the inlet valve (or main valve if not available). Turn off your water pump if applicable.
Step 2:
Unplug the UV system from the electrical outlet.
Step 3:
Relieve pressure by opening a downstream faucet. Close outlet shut-off valve if installed. If not, be prepared for backflow.
Step 4:
Remove the captive ground screw from the UV reactor ground lug.
Step 5:
Detach the lamp connector from the gland nut:
-
Push in
-
Turn ¼ turn counterclockwise
-
Gently pull cable to verify it's disconnected
Step 6:
Remove the UV lamp from the reactor while still attached to the connector.
Step 7:
Unscrew and remove the gland nut, exposing the quartz sleeve.
Step 8:
Gently twist and pull the sleeve out. Remove the o-ring.
Step 9:
Use a soft, lint-free cloth and CLR®, LIME-A-WAY®, or similar cleaner to wipe down the outside of the sleeve. Avoid getting moisture inside the sleeve.
Step 10:
Wipe with a separate dry cloth.
Step 11:
Reinstall the o-ring and quartz sleeve, following installation steps on page 9.
Cleaning the UV Sensor
The UV sensor should be cleaned annually, or more frequently if required by water quality.
UV Sensor Cleaning Procedure
Step 1:
Shut off the inlet valve (or main valve if not available). Turn off your water pump if applicable.
Step 2:
Disconnect power cord from outlet.
Step 3:
Open a downstream faucet to relieve pressure. Close outlet shut-off valve if installed.
Step 4:
Place a container or towel under the reactor to catch residual water.
Step 5:
Unscrew the sensor nut (counterclockwise) and slowly pull the UV sensor from its port.
Step 6:
Use isopropyl alcohol and a clean lint-free cloth to wipe the flat face of the sensor.
Step 7:

Operation
The Echo Water system comes with a feature-laden controller that incorporates both the lamp driver (ballast) and control features in one water-tight case. CAUTION: Prior to performing any maintenance on your UV system, you must always disconnect the power.
Echo Water Controller
This controller features a power factor corrected, constant current lamp driver with a universal power input. A full-colour LCD screen provides the user with a detailed description of the system’s performance in addition to providing any applicable fault messages and system diagnostics. All Echo Water controllers include an “infinite expandability port” located on the right side of the controller. Simply plug in an optional UV sensor module into the expandability port and the system will now monitor the UV intensity of the system!
Power-up Sequence
Upon start up, the controller will run through a diagnostic start-up and the sequence will be displayed as follows on the colour LCD:
Next, the controller checks for the installation of any optional modules that may be installed on the system. It first checks to see if a module is installed and then either initializes the module to function with the controller or returns a “not detected” screen and moves on to the next module. The screens will appear as follows:
-
UV Sensor Module Check
-
Solenoid Module Check
-
4-20 mA Module Check
-
Ethernet Module Check
-
Remote Alarm Module Check
Once the controller has finished checking for the installation of all available modules, a single screen is displayed showing which specific modules are installed and activated on this particular system.
Please Note: If the corresponding module icon is not displayed on this screen, then that module is not installed. If you believe the module is installed correctly, recheck the applicable connections to ensure a solid connection point and then restart the controller.
The controller then continues to optimize the lamp efficiency by waiting 60 seconds to allow the lamp to reach its optimum output. Finally, a final “start-up complete” screen is displayed.
Operational Screens
On systems without the UV monitor, the default screen shows the Echo Water Home Screen. At any point during operation, the user can scroll through the Home Screen, Lamp Life Remaining, and QR Code/Contact Info screens by pressing the button on the front of the controller.
On systems that have the UV module installed, the default screen shows the % UV Intensity. Users can scroll through % UV Intensity, Lamp Life Remaining, and QR Code screens with the front button.
% UV Intensity
If your system is equipped with a UV sensor, the % UV Output screens will indicate the level of UV intensity being detected by the sensor. This is always visible on the controller's Home Screen. Factors that affect % UV Output include poor water quality, scaling on the quartz sleeve and/or sensor, lamp failure, expired lamp, and sensor failure.
Once the UV output drops below 56%, the numbers and warning sign switch to red and a 15-second intermittent audible chirp sounds. When the output drops below 51%, the display switches to solid red and a constant audible signal is provided. The screens alternate between a solid red screen and a “Water may be unsafe for consumption” screen. The controller also sends a signal to deactivate the solenoid valve (if installed), shutting off water flow.
Lamp Countdown Sequence
The system counts down the number of days until a lamp change is required.
When the lamp has seven days remaining, the screen changes to a yellow caution screen and an audible chirp alerts the user. After the zero-day threshold is passed, the screen changes to solid red and cycles between “Lamp expired” and “Water may be unsafe for consumption” screens. The same chirp sounds continuously.
To defer the audible alarm, hold the controller button for five seconds. A screen will appear indicating deferral is activated, lasting seven days before resuming. This deferral can be repeated as needed. PLEASE NOTE: During lamp expiration and audible deferral, water may be unsafe for consumption and should not be consumed without another form of disinfection.
Lamp Countdown Reset Sequence
After changing the lamp, reset the controller by pressing and holding the button on the front, then plugging the power cord back into the wall. Hold the button for five seconds until you hear an audible chirp. Release the button to complete the reset.
Failure Modes
The Echo Water controller continuously monitors your UV system. If an issue is detected, both visual and audible signals will indicate the specific fault:
-
Lamp Failure: The controller emits a constant audible buzzer and visual warning.
-
UV Sensor Failure: If installed, the system cycles between “Sensor Failure” and “Water may be unsafe for consumption” with a buzzer.
-
Solenoid Module Failure: If installed, an intermittent 15-second buzzer and visual warning occur.
-
4-20 mA Module Failure: If installed, an intermittent 15-second buzzer and visual warning occur.
-
Remote Alarm Module Failure: If installed, an intermittent 15-second buzzer and visual warning occur.
-
-
Ethernet Module Failure: If installed, an intermittent 15-second buzzer and visual warning occur.
Expansion Modules
The Echo Water controller incorporates an “Infinite Expandability Port” (IEP). This port and custom communication protocol connect all modules and the UV sensor. Each module includes male and female connectors for daisy chaining. This modular design is simple and user-friendly.
Available Optional Modules:
-
Remote Alarm Module: Sends signals to remote monitors (buzzers, lights, alarm systems, PLCs, etc.). Normal: OK + COM connected. Fault: Fault + COM connected. Max rating: 1A-120VAC/VDC (16-22 AWG).
-
Solenoid Connection Module: Integrates a normally closed solenoid valve. The valve closes on lamp failure or low UV. Manual override is available.
-
4-20 mA Module: Transfers UV output data to remote devices. Use supplied cable with 16-22 AWG wire.
-
Ethernet Module: Connects the controller to a computer via Ethernet. (Currently in development.)
