WL15 INSTALLATION, FILTER FLUSHING, AND SANITIZING PROCEDURES
DANGER!
ELECTRICAL SHOCK HAZARD.
Only qualified personnel who have read and understand this entire manual should
attempt to install, or service this WL15 Water Dispenser, failure to do so could result in
death or serious injury. DO NOT plug into an electrical supply until specifically
instructed. Always unplug (isolate from power supply) to prevent electrical shock except
where electrical tests are specified.
WARNING!
ALWAYS SANITIZE BEFORE USE.
Sanitize before use to eliminate any potential microbiological contaminates.
CAUTION!
DRIP TRAY DRAIN.
The WL15 Water Dispenser has a drip tray that is NOT pre-plumbed to any drain or
collection device and must be periodically emptied.
WARNING!
USE PROPER PERSONAL PROTECTIVE EQUIPMENT
Always ensure proper ventilation and use proper personal protective equipment such as
gloves and eye protection when using chemicals. Refer to Material Safety Data Sheet for
specific requirements of each chemical product. Take all necessary precautions to
prevent sanitizer from contacting eyes, clothing, and any other surfaces in could damage
(carpets).
CAUTION!
HOT CIRCUIT IS NOT SANITIZED.
Water in the hot circuit is not sanitary until the temperature exceeds 77°C (171°F) for at
least 5 minutes.
CAUTION!
INDOOR USE ONLY.
Never expose to direct sunlight, heat sources, or ambient air temperature above 38°C
(100°F) or below 2°C (35°F). Install indoors and keep unit away from excessive humidity.
Never expose to freezing temperatures. Ensure there is adequate clearance around the
unit to allow refrigeration system condenser to dissipate heat. Warmer environments
require more clearance around the unit. Minimum clearance around all surfaces of the
machine is 2-inches. Installs where the ambient temperature exceeds 80°F, require a
minimum of 4-inches clearance for proper heat dissipation and efficient operation.
CAUTION!
USE UV STABILIZED SUPPLY LINES.
Feed the unit with a potable ambient or cold-water supply only. Feed water over 100° F
(37°C) can damage the treatment components. Water block devices and external leak
detectors are strongly recommended. Locate the unit as close to the water supply and
the electrical connections as possible.

Summary of Contents for WaterLogic WL15

  • Page 1 Only qualified personnel who have read and understand this entire manual should attempt to install, or service this WL15 Water Dispenser, failure to do so could result in death or serious injury. DO NOT plug into an electrical supply until specifically instructed.
  • Page 2  Sanitizing Cartridge  Food Coloring (optional) 1. Unpack the Waterlogic WL15 Water Dispenser and check exterior for damage. 2. Identify the ports on the back of the machine. All ports are clearly labeled. The top port of the drainage is not used, only the lower port is connected and will drain the hot tank.
  • Page 3 11. Continue dispensing alternating water types until both run clear and have no bleach smell to the water being dispensed. This may require several gallons to be flushed through the system. NOTE: Be sure all sanitizer has been flushed from the system before installing the filters.

  • Page 4 5. Dim or shield the overhead lights and peer into the top of the UV module. The blue glow indicates the lamp is lit. If it is not, check the wire connections to the PCB and the bulb itself. WL15 Manual Page 36 – Revision: 4-15-22...
  • Page 5: Hot Water

    DANGER! HOT WATER. The Waterlogic WL15 Water Dispenser produces Hot Water up to 87°C (188°F). Water above 52°C (125°F) can cause severe burns or scalding. Hot water should be dispensed carefully into insulated container to avoid injury.
  • Page 6 CHANGING THE UV BULB 1. Remove the upper panel of the WL15 by removing the screws shown in red and set the upper panel aside. 2. With the upper panel removed, locate the UV module. The UV bulb is inserted from the top with the wires running out and to the PCB.
  • Page 7 WL15: HOT TANK RESET 1. Remove the upper panel of the WL15 by removing the screws shown in red and set the upper panel aside. UNPLUG THE MACHINE FROM THE POWER SOURCE. 2. Locate the hot tank. Then locate the high limit overload thermostat on the tank. From this perspective, it will be difficult to see.
  • Page 8 CAUTION! STAINLESS STEEL TANK DESCALING. The Hot Tank is made from stainless steel. Ensure descaling solution is compatible with stainless and always flush the WL15 Water Treatment System completely. Dispose in an environmentally safe manner. Materials Needed:  Personal Protective Equipment. Rubber or Nitrile Safety Gloves and Protective Eyewear ...
  • Page 9 (if food coloring was used). This may require up to a gallon of water dispensed from the hot tank to completely flush all descaling agent out of it. 8. Once flushed of descaling agent, turn the Hot switch on at the back of the unit. WL15 Manual Page 41 – Revision: 4-15-22...
