SERVICING INSTRUCTIONS (continued) 

17 

CAUTION:  

CHEMICAL BURN 
HAZARD

 

Deliming chemicals may be 
caustic.  Wear appropriate     
protective gloves and goggles 
during this procedure. 
Never siphon deliming      
chemicals or solutions by 
mouth. 
This operation should only be 
performed by qualified and    
experienced service personnel. 
 
 

IMPORTANT: 

 DO NOT spill, 

splash or pour water or deliming 
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     
deliming solution.  Take care to 
keep all internal components 
dry. 
 
 

NOTE:

  Repeat steps 4 thru 5 

as required to remove all scale 
and lime build-up. 
 
 

NOTE: 

 Normally, silicone 

hoses do not need to be        
delimed.  Should deliming 
hoses become necessary, 
Bloomfield recommends        
replacing the hoses. 

PROCEDURE:  Delime the Water Tank  

 
PRECAUTIONS:     Disconnect brewer from electric power.  
                                Allow brewer to cool. 

 
FREQUENCY:        As required (Brewer slow to heat) 

 
TOOLS:                   Deliming Solution 
                                Protective Gloves, Goggles & Apron 
                                Mild Detergent, Clean Soft Cloth or Sponge 
                                Bristle Brush, Bottle Brush 
                                Large Sink (or other appropriate work area) 

 

1.    Disconnect brewer from electric power.  Turn off the water 
       shut-off valve and disconnect the water supply line from the 
       brewer inlet fitting. 

 
2.    Remove the tank lid assembly as described on page 13. 

 
3.

Remove the water tank from the brewer body by lifting 
straight up.  Empty all water from the tank.  Set the tank back 
into the brewer. 

 
4.    Mix 2 quarts of deliming solution according to the            
       manufacturer’s directions.  Carefully pour the deliming 
       solution into the water tank.  Lower the lid assembly back       
       onto the 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 internal components of lid assembly with 
       clear water.  Using a stiff bristle brush, scrub the heating    
       element (and faucet water coil on automatic brewers) to            
       remove lime and calcium build-up.  Rinse with clean water.  
       Store lid assembly in a safe location . 

 
6.    Remove the tank from the brewer and empty.  Using a stiff 
       bristle brush, scrub the interior of the water  tank to remove 
       lime and calcium build-up.  Rinse with clean water.  
7.    Set the tank back into the brewer.  Reassemble the tank lid to 
       the water tank.  Make sure the gasket is properly in place, 
       then reinstall the hold-down strap. 

 
8.    Reinstall wiring to heating element and thermostat.  Reinstall 
       the hi-limit thermostat (if removed).  For automatic brewers, 
       reassemble piping for the faucet.  Verify that all internal    
       components are dry, then reinstall the top panel. 

 
10. Reconnect brewer to electrical supply and, for automatic 

brewers, reconnect water supply. 

 
11. Install the brew chamber without filter paper or grounds.    
       Run at least three full brew cycles and discard all water    
       generated. 

 
12. Brewer is ready to use.
