 the water supply and disconnect water supply from the 
 brewer inlet fitting. 
 
 2. Remove the top panel to gain access to internal 
 components. 
 
 3. Disconnect water level sensor and water temperature 
 sensor from the controller. On 120V units, slip hi-limit 
 thermostat from under its holder clip. Disassemble the 
 three lid clips and lift the lid off of the water tank. Store 
 lid assembly in a safe location. 
 
 4. Mix de-liming solution according to the manufacturer’s 
 directions. Add the de-liming solution to the water tank. 
 Set lid assembly back on tank. Allow to sit for 30 
 minutes, or as directed by the manufacturer. 
 
 5. At end of soaking period, remove lid assembly from tank. 
 Thoroughly rinse interior components of lid assembly 
 with clear water. Wipe temperature sensor and water 
 level sensor with a clean, soft cloth. Store lid assembly 
 in a safe location. 
 
 6. Using a stiff bristle brush, scrub the coils of the heating 
 element and the interior surfaces of the water tank. 
 
 7. Siphon the used solution and loose lime/scale into an 
 appropriate container. Dispose of the used solution as 
 required by local ordinances. 
 CAUTION: Never siphon by mouth. Serious injury can 
 result!

 thoroughly, then siphon the rinse water into an 
 appropriate container for disposal. Again, take care to 
 keep all internal components dry. 
 
 9. Reassemble the tank lid to the water tank. Make sure 
 the gasket is properly attached to the lid before 
 assembling the lid clips. Re-connect the water level and 
 temperature probes, then reinstall the hi-limit thermostat 
 (if removed). Verify that all internal components are dry, 
 then reinstall the top panel. 
 
10. Reconnect brewer to water and electrical. Run and 
 discard at least three full decanters from the faucet.
