INSTALLATION (continued)
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
CAUTION:
ELECTRICAL
DAMAGE
PLUMBER’S INSTALLATION INSTRUCTIONS (AUTOMATIC
BREWERS)
Brewer should be connected to a POTABLE WATER, COLD
WATER line. Flush water line before connecting to Brewer.
DO NOT plug in or energize this
appliance until all Installation
Instructions are read and
followed. Damage to the
Brewer will occur if these
instructions are not followed.
DO NOT use a saddle valve with a self-piercing tap for the water
line connection. Such a tap can become restricted by waterline
debris. For systems that must use a saddle tap, shut off the main
water supply and drill a 3/16” (minimum) tap for the saddle
connection, in order to insure an ample water supply. Remember
to flush the line prior to installing the saddle.
IMPORTANT:
The brewer must be installed on a water line with average
pressure between 20 PSI and 90 PSI. If your water pressure
exceeds 90 PSI at anytime, a pressure regulator must be
installed in the water supply line to limit the pressure to not more
than 90 PSI in order to avoid damage to lines and solenoid.
Tank must be full of water
before connecting brewer to
electric power. Heating
elements will be damaged if
allowed to operate without
being fully submerged in water.
See instructions for filling tank,
page 8.
Damage caused by operating
the brewer without water in the
tank is NOT COVERED BY
WARRANTY.
A water shut-off valve should be installed on the incoming water
line in a convenient location (Use a low restriction type valve,
such as a 1/4-turn ball valve, to avoid loss of water flow thru the
valve.
NSF requires that the brewer be able to be moved for cleaning
underneath. Loops of copper tubing will satisfy this requirement.
See Figure 3 below.
NOTE: Water supply inlet line
must meet certain minimum
criteria to insure successful
operation of the brewer.
Bloomfield recommends 1/4"
copper tubing for installation of
less than 12 feet and 3/8" for
more than 12 feet from a 1/2"
water supply line.
NOTE: This equipment must be
installed to comply with
applicable federal, state and
local plumbing codes and
ordinances.
Fig. 3 Water Supply Installation
In some areas, local codes require a backflow preventer (check
valve) to be installed on the inlet water line. If a backflow
preventer is used, you must install a water hammer arrester in
the incoming line, between the backflow preventer and the
brewer inlet, as far away from the brewer as space will allow.
This will relieve the excessive back pressures that can cause
faucet leaks and solenoid malfunctions.

INSTALLATION (continued)
ELECTRICIAN’S INSTALLATION INSTRUCTIONS
WARNING:
REFER TO ELECTRICAL SPECIFICATIONS - Page 1
Check the nameplate to determine correct electrical service
required for the Brewer to be installed.
SHOCK HAZARD
Brewer must be properly
grounded to prevent possible
shock hazard. DO NOT
assume a plumbing line will
provide such a ground.
IMPORTANT: Before connecting to electricity, make sure
automatic brewers are connected to the water supply.
NOTE: Does not apply to 0443 and 0471 pour-over brewers.
Electrical shock will cause death
or serious injury.
All models are equipped with a cord and plug. They require a
115 - 125 volt 20 amp circuit (50/60 Hz, 2 wire plus ground, with
NEMA 5-15R or 5-20R Receptacle).
IMPORTANT:
See Figure 4 at right.
Supply power must match
nameplate for voltage and
phase. Connecting to the
wrong voltage will damage the
brewer or result in decreased
performance. Such damage is
not covered by warranty.
IMPORTANT:
Do not connect brewer to
electrical power until you have
filled the tank. See instructions
on page 8.
IMPORTANT:
The ground prong of the plug is
part of a system designed to
protect you from electrical shock
in the event of internal damage.
Never cut off the ground prong
nor twist a blade to fit an
existing receptacle. Contact a
licensed electrician to install the
proper circuit and receptacle.

This operation should only be
performed by qualified and
experienced service personnel.
1. Disconnect brewer from electric power. For automatic
brewers, 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 14.
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.
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.
IMPORTANT: DO NOT allow
any internal components to
come into contact with the
deliming solution. Take care to
keep all internal components
dry.
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.
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.
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.
