TROUBLESHOOTING SUGGESTIONS  
Proper installation, professional operation and consistent maintenance of this appliance will ensure  
that it gives you the very best performance and a long, economical service life.  
IMPORTANT:  
This is a general guide only. Always refer to the specific manual for your equipment. The Owners  
Manual contains electrical specifications as well as the information needed to properly install the  
appliance, and to use, care for and maintain or repair the appliance in a manner which will ensure  
its optimum performance.

GENERAL USE AND CARE  
KEEP IT DRY  
3. Use the proper tools in the proper way to  
clean your Bloomfield equipment:  
a. Soft cloth and plastic scouring pads are  
generally safe to use on stainless steel.  
b. Stainless steel pads may be used ONLY  
IF the scrubbing motion is in the direction  
of the visible grain. DO NOT use a  
circular motion.  
While all equipment must be cleaned regularly, it  
is important that water not be introduced into the  
interior. Water will degrade insulation, damage  
equipment components and create an electric  
shock hazard.  
1. Never submerge brewers, airpots or servers in  
water unless it is specifically stated in the  
Owners Manual that it is safe to do so.  
c. In the absence of visible grain, use only  
soft cloth or plastic pads. Scrub only in a  
linear motion along the longest axis of the  
equipment.  
d. Daily cleaning should be performed with a  
clean, soft cloth MOISTENED with water  
and mild detergent, and rinsed with a  
clean, soft cloth MOISTENED with clean  
water.  
2. Do not use a hose or jet stream to wash  
equipment, or to wash over, under or around  
equipment. Bloomfield brewers are not jet  
stream approved.  
3. Do not spill, pour or spray water onto or over  
any warmers, wiring, controls or control panel.  
4. Bloomfield brewers should never become  
heavily soiled. However, if heavy cleaning  
IS required, use only non-chloride and non-  
ammonia cleansers:  
CARE OF STAINLESS STEEL  
1. Bloomfield brewers are constructed of high  
quality stainless steel, As long as the  
stainless steel surface is intact, the equipment  
will not rust or corrode.  
a. DO NOT use any cleanser listed as  
“chlorinated”.  
b. DO NOT use any cleanser listing  
“ammonia” or “ammonium” in its contents.  
c. Contact your cleaning materials supplier  
for suitable alkaline cleansers.  
2. The surface can be damaged by mechanical  
abrasion, hard water deposits and chlorine:  
a. NEVER use steel wool, wire brushes or  
metal scrapers to clean the equipment.  
These will damage the surface of the  
stainless steel.  
DESCALING AND DELIMING  
b. Hard water deposits left behind when  
water is evaporated can damage the  
surface.  
1. In areas where tap water has a high mineral  
content, brewer heating elements and tanks  
may develop lime deposits.  
c. Chlorides from chlorinated cleansers,  
calcium/lime/rust removers (e.g. muriatic  
acid), even heavily chlorinated city water  
can attack the surface and allow the  
stainless steel to rust.  
d. DO NOT use any highly caustic cleaners  
on equipment. Use of highly caustic  
cleaners will attack the surface and allow  
the stainless steel to rust.  
2. Regular cleaning with a coffee brewer  
deliming cleaner is recommended to prevent  
the build-up of lime and scale deposits.  
Recommendation: A water softening device  
or a cartridge-type filtration device may be  
used to minimize lime build-up.  
e. LIMIT USE of strong caustic cleaners on  
equipment. Rinse thoroughly with a  
vinegar and water solution to neutralize  
any residue. Failure to do so may cause  
damage to the surface and allow the  
stainless steel to rust.  
f. Cleansers containing ammonia will attack  
the surface and allow the stainless steel to  
rust.

water shut-off valve and disconnect the water supply line  
from the brewer inlet fitting.  
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.  
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.  
IMPORTANT: DO NOT allow  
any internal components to  
come into contact with the  
deliming solution. Take care to  
keep all internal components  
dry.  
4. Mix 2 quarts of deliming solution according to the

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 .  
NOTE: Repeat steps 4 thru 5  
as required to remove all scale
