SERVICING INSTRUCTIONS - DE-LIMING HEATER TANK
CAUTION -
CHEMICAL BURN
HAZARD
De-liming chemicals are caustic.
Wear appropriate protective
gloves and goggles during this
procedure.
CAUTION -
CHEMICAL BURN
HAZARD
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.
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 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.
11. Brewer is ready to use.
