Safety Considerations Although your UV system has been manufactured to the highest safety standards, care must be followed when operating and/or maintaining your system. 1. Before servicing this equipment, disconnect the power cord from the electrical outlet. 2. Energy given off by the UV lamp is 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.
Water Quality Parameters UV disinfection is extremely effective against microorganisms but only if the UV light can pass through the water it needs to treat. This means that the quality of your water is very important in order to ensure complete disinfection. Treated water should be tested for at the least the parameters listed below.
Assembly The rack-mount UV system is designed as a do-it-yourself (DIY) system with a single inlet and outlet port. Unpack the system and ensure all the components are included in the box. Your system is shipped with the following components: 1.
System Sizing All UV systems are rated for a specific flow rate in water that meets the quality parameters on page 5. PLEASE NOTE increasing the flow above the system rating or disinfecting water that does not meet the quality parameters will decrease the dose and therefore compromise the microor- ganism inactivation.
PLEASE NOTE: All UV disinfection systems are intended for indoor use only as they should not be exposed to the elements. The controller will require a ground fault circuit interrupter (GFCI or GFI) outlet and should be mounted beside or above the reactor. Orientation This system has the ambidextrous capability of being able to have the main water inlet enter from either the left hand side or right hand side of the unit.
Installation Step 1: Once both the orientation and location have been selected, securely fasten the rack to a suitable back- ing. As the rack system is extremely heavy when filled with water, it is imperative that the rack be mounted with suit- able fasteners for the particular installation.

Figure 5. Cartridge Removal Step 9: Install the UV sensor (systems with optional UV sensor). Align the flat portion so it faces the gland nut end and matches up with the half metal lip on the sensor port (see Figure 6).

The key always comes packaged with the lamp and sits on the connector. With the key removed from the lamp, orient it so the label is upright and facing you.
System Disinfection With a new installation, or any time the UV system is shut down for service, without power, or is inoperative for any other reason, the lines in the home or facility could be contaminated. Use the following steps to fully disinfect the lines throughout the entire home or facility. Step 1: Check for and remove any “dead ends”...
Step 10: Dry the sleeve with separate cloth. Step 11: Replace the o-ring and slide the sleeve back into the reactor following steps 7 and 8 from the installation section of the manual. Cleaning the UV Sensor Depending on the water quality, the UV sensor may require periodic cleaning. At a minimum, the UV sensor should be cleaning on an annual basis.
LTW-4 Controllers Simplistic in operation, these systems feature a tri-colour LED that indicating system status and a 4-digit display to indicate lamp life remaining. Pressing the button will change the display to indicate total running time. When the UV lamp is on and within its operating age, the LED will be green.
A final module screen is displayed showing which specific modules were initialized. The controller then displays the lamp optimization screen for 60 seconds to allow the lamp to reach its optimum output. Finally, a final “start-up complete” screen is displayed. The system will now be ready to disinfect water flow.
audible chirp every audible chirp every constant audible cycles with red low 15 seconds 15 seconds alarm UV screen Lamp Countdown Sequence The system counts down the number of days until a lamp change is required. LTW-5 LTW-4 At thirty days remaining, the LED or display screen will change to a yellow caution indicator. At seven days remaining, the system will additionally repeat an audible chirp.
System Service Suggested LTW-5 controllers will display the System Service Suggested Screen every 6 months to remind consumers to maintain both their UV and other prefiltration. This will serve as a prompt only and will not put the system into alarm. To clear this condition simply press the button located below the screen.
System Troubleshooting Hard Alarms: The following give a constant audible alarm. If present, the solenoid valve is closed, and the 4-20, remote alarm and WiFi modules transmit the alarm. System Display Problem Resolution Reset lamp protection circuit -unplug unit for 10 seconds. The system has detected Replace the lamp with the a problem with the...
Soft Alarms: The following remaining errors give a 15 second audible chirp only System Display Problem Resolution Ensure all modules are connected properly to the system and to each other. Modules can be tested The module indicated is individually by plugging in no longer communicat- one at a time and cycling ing to with the system.
Expansion Modules LTW-5 controllers incorporate an “Infinite Expandability Port” (IEP) which allows for expansion to the UV sensor and all other modules. Each module (including the sensor) comes with both a male and female connection. Connect any device to the controller and all subsequent devices are then connected into the female end of last device added in a “daisy chain”...
