Page 4: Safety Considerations
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. -
Page 5: Water Quality Parameters
<0.1 ppm (0.1 mg/L) UVT (transmittance): >85% (Please contact LIGHTWAVE if water has a UVT that is less than 80% for pre-treatment recommendations) You can have your water tested at a private analytical laboratory or by your local dealer. It is always recommended to install pre-filtration of at least 5 microns prior to a UV disinfection system. -
Page 6: Assembly
Assembly Unpack the system and ensure all the components are included with the system. Your system is shipped with the following components: STANDARD OUTPUT LAMP SYSTEMS LAMP GLAND NUT CONTROLLER LTW-320006 4.1 SYSTEMS LTW-RCB401 O-RING 5.1/6.1 SYSTEMS LTW-300038 LTW-RCB5601 UV LAMP LTW-RL210 “-02”... - Page 7 HIGH OUTPUT LAMP SYSTEMS LAMP GLAND NUT LTW-320006 CONTROLLER O-RING 4.1 SYSTEMS LTW-300038 LTW-RCHO412 5.1/6.1 SYSTEMS LTW-RCHO5612 UV LAMP LTW-RL210HO “-05” series LTW-RL330HO “-10” series CLAMPS LTW-RL420HO “-15” series LTW-RL600HO “-25” series LTW-RL950HO “-40” series SLEEVE SPRING 310039 GLOW PLUG QUARTZ SLEEVE LTW-300016 Complete Assembly LTW-QS210 “-05”...

Page 8: System Sizing
(See Figure 1). For Point of Use (POU) systems, install the unit just before the faucet. LIGHTWAVE recommends that a 5 micron filter be installed before the UV system for a final polishing step before the water is disinfected. -
Page 9: Installation
To facilitate lamp removal, ensure there is enough space at the lamp connector end to safely remove the UV lamp and/or quartz sleeve (See Figure 2). The controller will require a ground fault circuit interrupter (GFCI or GFI) outlet and should be mounted beside or above the reactor. PLEASE NOTE: All UV disinfection systems are intended for indoor use only as they should not be exposed to the elements. - Page 10 Step 6: Once the system has been plumbed in, gently remove the quartz sleeve from its packaging being careful not to touch the length with your hands. The use of cotton gloves is recommended for this pro- cedure as oils from the hands can leave residue on the sleeve and lamp which can ultimately block the UV light from getting to the water.
- Page 11 Step 11: Always hold UV lamps by their ceramic ends, not by the lamp quartz. Remove the lamp from its packaging. Again, the use of cotton gloves is recommended. Remove the lamp key from the lamp’s connector and set it aside for the next step. Be careful to not touch the key’s exposed contacts.

Page 12: System Disinfection
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”... -
Page 13: Cleaning The Uv Sensor
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 cleaned on an annual basis. -
Page 14: Ltw-4 Controllers
When the UV lamp is not on or the lamp life has expired, the LED will be illuminated red and an audible buzzer will be sounding. To remedy this condition, the UV lamp must be replaced with a new genuine LIGHTWAVE UV lamp. LTW-H4 LTW-4... -
Page 15: Ltw-5 Operational Screens
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. -

LTW-5 LTW-6 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. -

Follow the steps under the “System Disinfection” heading. Boil Water Advisory: If any failure occurs on a LIGHTWAVE UV system, the water must not be used for human consumption until the system is returned to a safe operational mode.

Page 20: Temperature Management Devices
Temperature Management Devices Your LIGHTWAVE UV system is designed to run continuously to ensure optimal disinfection. However, during periods when no water is drawn through the system, the energy from the disinfection process can cause the temperature of the water inside the chamber to rise. In extreme situations elevated water temperature or the fluctuation in temperature can lower the output of the UV lamp. - Page 21 REMOTE ALARM CONNECTION MODULE: Allows for a connection to a remote device such as a buzzer, light, alarm system, PLC, etc., via a pair of contacts. In normal operation the OK and COM contacts will be connected, and in a fault condition (Low UV, Lamp fail, Power Fail), the Fault and COM contacts will be connected.
