2 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. 4. Inspect the Quartz Sleeve O ring for wear or damage and replace as necessary. 5. Ensure there is adequate (minimum of 2 ) clearance around the unit and clean the condenser grill and compressor fan to provide efficient cooling system operation. 6. Sanitize the Cold Tank per instructions in the pre installation procedures. 7. Clean and sanitize external surfaces of the unit. Use soap and water or chemicals that are compatible with ABS plastic and will not damage or degrade the product surfaces. 8. Remove and clean the Faucet. Replace as needed. WARNING! SANITIZER MAY CONTAIN HAZARDOUS CHEMICALS. Use of proper personal protective equipment such as rubber gloves and eye protection is required. WL270 Manual Page 13 Revision

4 HOT TANK DESCALING INSTRUCTIONS The Hot Tank requires removal of mineral deposits (descaling) on a regular basis. Typically descaling should take place every 6 to 12 months to preserve the long term health of your unit. Use non toxic cleaner such as ScaleKleen, DEZCAL, 20% Citric Acid Solution, or Undiluted Vinegar Solution to remove mineral deposits as directed by the manufacturer depending upon filtration and local water conditions. Descaling is an important process that removes calcium deposits, or scale, that can build up inside a tank over time. Calcium and scale is non toxic but left unattended will hinder your unit s performance. WARNING! PERSONAL PROTECTIVE EQUIPMENT REQUIRED. Always ensure proper ventilation and use rubber or nitrile gloves and eye protection when using chemicals. Refer to Material Safety Data Sheet for specific requirements of each product. CAUTION! STAINLESS STEEL TANK DESCALING. The Hot Tank is made from stainless steel. Ensure descaling solution is compatible with stainless and always flush the unit completely. Dispose in an environmentally safe manner. Materials Needed: Personal Protective Equipment. Rubber or Nitrile Safety Gloves and Protective Eyewear Phillips Screwdriver Temperature Gauge Water Pitcher or Container to collect water from the faucet 5 gallon container or drain basin Citric Acid Based Cleaner ¼ Plastic Tubing, at least 4 feet in length, and assorted ¼ quick connect fittings Sanitizing Cartridge Food Coloring 1. Check to ensure that the Red Heater and Compressor Power Switch is the O=OFF position. NOTE: Switches have internal LED that illuminates when placed in I=ON position. 2. Turn off the water supply and unplug the unit. 3. Remove top Cover 4. Remove Reservoir Lid 5. Remove Hot Tank Drain cap on back of unit and allow all water to drain from unit. WL270 Manual Page 15 Revision

5 6. When unit has finished draining, replace Hot Tank drain cap. 7. Remove reservoir from unit. 8. Mix descaler per instructions. 9. Add descaling mixture to the Hot Tank through the Hot Tank fill portal located in the water inlet port. Hot Tank fill portal to add descaling mixture to. 10. Replace Reservoir. 11. Turn on water supply and plug in unit. 12. Allow reservoir to fill. 13. Turn on the Red Heater and Compressor Power Switch. I=ON position. 14. Allow descaling mixture to remain in Hot Tank for 15 minutes (exposure time may be affected by local water conditions). 15. Flush unit until all descaler is removed. WARNING! HOT WATER HAZARD. Unit Produces Very Hot Water and Steam. Always use insulated and chemically compatible containers and let unit cool down before draining the Hot Tank to avoid injury. CAUTION! MUST REPLACE HOT TANK 3 5 YEARS DEPENDING ON USAGE. The Hot Tank and its controls must be replaced a minimum of every 3 5 years depending on usage to ensure efficient and dependable operation. WARNING! REINSTALL ALL PANELS AND COVERS. Always reinstall all panels, protective covers, and fasteners after servicing equipment. Failure to do so could result in severe personal injury and will void the certifications and warranty of the equipment. WL270 Manual Page 16 Revision

6 RESETTING THE HOT TANK OVERLOAD OR HIGH LIMIT SAFETY 1. Turn off Red Heater and Compressor Power Switch O = OFF on rear of unit. 2. Unplug the Power Cord from rear of unit. 3. Remove 4 Phillip Screws from the Access Panel on rear of unit and Lower Access Panel. Locate protective metal box on rear of Hot Tank. Push down on top of metal box to access thermostat and overload 4. Press the reset button Reattach the metal box by depressing the top flap of the metal box so it snaps back into its original position on the Hot Tank. WL270 Manual Page 17 Revision

7 7. Replace the Access Panel and 4 Philips screws. 8. Plug in the Power Cord. 9. Make sure the hot and cold tanks are filled with water BEFORE turning on the Red Heater and Compressor Power Switch CAUTION! NEVER TURN ON HEATER BEFORE FILLING HOT TANK. Red Heater and Compressor Power Switch must be in the O=OFF position while the Hot Tank is empty. Damage could occur within one minute and the overload (high limit) will require manual reset if heater is turned on with an empty Hot Tank. 10. Verify the cooler is fully operational before installing it at the customers site. WL270 Manual Page 18 Revision
