SERVICING INSTRUCTIONS — DE-LIMING 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 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.
Wipe temperature sensor and water level sensor with a
clean, soft cloth. Thoroughly rinse interior components
of lid assembly with clear water. 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.
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 servers as normal
brew.
11. Brewer is ready to use.
CAUTION - CHEMICAL
BURN HAZARD
De-liming chemicals are caustic.
Wear appropriate protective gloves
and goggles during this procedure.
Never siphon de-liming chemicals
or solutions by mouth.
This operation must only be
performed by qualified and
experienced service personnel.
IMPORTANT: DO NOT spill,
splash or pour water or de-liming
solution into or over any internal
component other than the inside of
the water tank.
IMPORTANT: DO NOT allow any
internal components to come into
contact with the de-liming solution.
Take care to keep all internal
components dry.
NOTE: Repeat steps 4 thru 7 as
required to remove all scale and
lime build-up.
NOTE: Normally, silicone hoses
do not need to be de-limed.
Should de-liming hoses become
necessary, Bloomfield Industries
recommends replacing the hoses.
