Expansion Chamber in the top of the tank except for WL270 (GF) units. The Vent Chamber allows for expansion of the water when it is heated. The chambers are separated by a welded‐in tank baffle. Water always flows into the bottom of the tank and out the top to the faucet. The hot tank outlet tube has a restrictor in its base. This ensures the reservoir is always full by allowing more water in than out. There is a small hole in the side of the tank outlet tube that allows air and water to pass into the vent chamber as it is heated. Water in the vent chamber is suctioned back through the outlet tube vent hole when water is dispensed. Expansion of water as it is heated in the reservoir will push the water out the faucet when the outlet tube vent hole becomes plugged with debris or scale. The small Outlet Vent Hole is susceptible to scale build up and is a key indicator that descaling is required. It is critical to descale the hot tank through the vent line and outlet line on a regular basis to prevent this problem. Descaling through the inlet and/or outlet lines only will not clean the vent chamber and outlet vent hole properly. WL250 Manual Page 61 ‐ Revision: 12‐12‐2018 ...

Bypass filters before starting the Descaling Procedure. 2. Put descaler per directions and 3 drops of food coloring into the descaling cartridge. 3. Connect descaling cartridge to the inlet water supply and connect to inlet bulkhead fitting on the back of the unit. Turn on Water Supply. 4. Select Hot Water and depress the Main Dispensing Button on the Front Control Panel until descaling solution (colored water) comes out of the faucet.

5. Turn off water supply and remove sanitizing cartridge from inlet water supply. Reconnect water supply to inlet fitting. 6. Allow descaling solution to remain in the Hot Tank for 15 minutes (length of time may vary depending on water conditions). 7. Place a pitcher, catch basin or other container under the faucet of the WL250. 8. Flush the Hot Tank until water runs clear. 9. Once clear Water dispenses from the faucet the Hot Tank has been descaled. Always ensure unit is performing to the customer’s satisfaction. 10. Replace Filters. WARNING! HOT WATER. The WL250 Water Treatment System 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. 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 three to five 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. ...
