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.

1

GENERAL USE AND CARE

KEEP IT DRY

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.

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.

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.

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.
b. Hard water deposits left behind when
water is evaporated can damage the
surface.
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.
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.

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.
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.

4. Bloomfield brewers should never become
heavily soiled. However, if heavy cleaning
IS required, use only non-chloride and non­ ammonia cleansers:
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.

DESCALING AND DELIMING

1. In areas where tap water has a high mineral
content, brewer heating elements and tanks
may develop lime deposits.

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.
