WARNING! Read and understand the contents of this manual before attempting to service
WL500 Water Treatment System. Failure to follow the instructions in this manual could result
in death, serious personal injury, or severe property damage. Only trained and qualified
technicians should attempt to install, maintain, or service Waterlogic Equipment.
1. Visually inspect all electrical and water connections for signs of wear or damage.
DANGER! HIGH VOLTAGE ELECTRICAL HAZARD. Unplug before inspection and service.
2. Waterlogic recommends changing the UV Lamp every 12 months.
Note: UV Lamp Sensor is temperature sensitive. During extended periods of use, especially when
filing or draining the unit, when water is not being dispensed, UV Lamp Sensor can overheat,
initiating a UV Fault. If this occurs, turn off the unit for 5 minutes and allow sensor to cool before
resuming operation.
WARNING! ULTRAVIOLET RADIATION. Protect your skin and eyes against ultraviolet rays.
Never look directly at an operating UV light. Disconnect before removing UV Lamp.
CAUTION! UV LAMPS ARE HAZARDOUS. Lamps are considered Hazardous Waste and must be
disposed of accordingly. Refer to Product MSDS sheet for details.
UV DECLARATION: The UV Lamp in this appliance conforms to the applicable provisions in the Code
of Federal Regulations(CFR) requirements including; Title 21, Chapter 1, Subchapter J, Radiological
Health.
3. Clean the Quartz Sleeve that surrounds the UV Lamp with a non‐abrasive cloth, descaling solution,
or ultrasonic bath if needed when changing UV Lamps.
CAUTION! UV SYSTEM IS FRAGILE. Never handle the UV lamp or Quartz Sleeve with bare hands.
UV Lamp and quartz sleeve must be free of oils and contaminants to ensure proper operation.
Use a soft non‐abrasive cloth to clean UV lamps.
4. Inspect the Quartz Sleeve O‐ring for wear or damage and replace as necessary.
5. Test UV Lamp and UV sensor (CDS) is working by removing the sensor from the Retaining Nut and
covering the end to produce an audible alarm (continuous beep) and "UV Fault" on the display.
6. The Filters should be replaced every 6 months or 2,000 gallons, whichever comes first. Local water
conditions will dictate your exact Filters requirements and service intervals. Flush 5 gallons of water
through the Filters to rinse carbon fines. Do not rinse the Filters through the unit Solenoid Valve(s)
and Tanks if at all possible to avoid contamination.
7. Reset Filters Life Timer if enabled. See programming instructions for details.
