SERVICING INSTRUCTIONS — DE-LIMING WATER HEATER TANK
1. Disconnect brewer form the electrical supply. Turn off
the water supply and disconnect water supply from the
brewer inlet fitting.
2. Remove the top panel or top warmer section 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!
8. Fill the water tank with clean tap water. Rinse
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.
Install the brew chamber without filter paper or grounds,
then run and discard at least three full decanters as
normal brew.
