CAUTION -  
CHEMICAL BURN 
HAZARD

 

Deliming chemicals are 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 ex-
perienced 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, other 
than those in the water system, 
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.

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 to remove lime and calcium 
       build-up.  Rinse with clean water. Store lid assembly in a safe

       the water tank.  Make sure the gasket is properly in place, 
       then reinstall lid clamps. 

 

8. Reinstall wiring to heating element and thermostat.   
       Verify that all internal components are dry, then reinstall the 
      top panel. 

 

10. Reconnect brewer to electrical supply and reconnect water 

supply. 

 

11. Install the brew chamber without filter paper or grounds.
