SERVICING INSTRUCTIONS — DE-LIMING HEATER TANK

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.

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.
