INSTALLATION INSTRUCTIONS
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
IMPORTANT:
REFER TO EXPLODED VIEWS PAGES 16 thru 19 FOR
COMPONENT NAMES/NUMBERS
To enable the installer to make
a quality installation and to
minimize installation time, the
following suggestions and tests
should be done before the
actual unit installation is started:
1. Unpack the unit. Inspect all components for completeness
and condition. Ensure that all packing materials have been
removed from the unit.
2. (See page 13.) Remove the Top Warmer Unit (#106) or Top
Cover (#102) and inspect the internal components. Verify
that all wiring and hoses are connected and are properly
seated. Verify that the Tank Cover Assembly (#9) and Tank
Cover Gasket (#6) are securely installed. Reinstall top.
CAUTION: Equipment
Electrical Damage
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.
3. (See page 13.) Verify that the Spray Head (#24) and Spray
Head Gasket (#23) are properly installed.
LEVELING THE UNIT
1. Verify that an adjustable leg is installed at each corner of the
brewer.
2. Set Brewer in its operating location.
CAUTION: Unstable
Equipment Hazard
3. Level the Brewer. A spirit level should be placed on the top
of the unit, at the edge, as a guide when making level
adjustments.
It is very important for safety
and for proper operation that the
brewer is level and stable when
standing in its final operating
position. Provided adjustable,
non-skid legs must be installed
at each corner of the unit.
Failure to do so will result in
movement of the brewer which
can cause personal Injury and/
or damage to brewer.
4. Level the unit from left to right and front to back by turning the
adjustable feet. Be sure all four feet touch the counter to
prevent tipping.
PLUMBER’S INSTALLATION INSTRUCTIONS
1. Brewer should be connected to a POTABLE WATER, COLD
WATER line. Flush water line before connecting to Brewer.
2. 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.
NOTE: Water supply inlet line
must meet certain minimum
criteria to insure successful
operation of the brewer.
3. 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 filters, lines
and solenoid.
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.

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.
5. NSF requires that the brewer be able to be moved for
cleaning underneath. A flex line or loops of copper tubing
will satisfy this requirement.

WATER
SUPPLY
Electrical shock will cause death
or serious injury.
6. In some areas, local codes require a backflow preventer
(check valve) to be installed on the inlet water line. If a back
flow 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.
IMPORTANT: Do not attempt to
override the automatic tank fill
feature which requires that the
tank must be full of water to
start operations. Any attempt to
override this feature will void
the warranty.
IMPORTANT:
ELECTRICIAN’S INSTALLATION INSTRUCTIONS
Before connecting to electricity,
make sure the E-Max™ LX has
been properly connected to the
water supply.
REFER TO ELECTRICAL SPECIFICATIONS - Page 1
Check the nameplate to determine correct electrical service
required for the Brewer to be installed.
IMPORTANT:
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.
NOTE: Models 2212 & 2272 require a 115 - 125 V 15A circuit
(50/60 Hz, 2 wire plus earth ground, with
NEMA 5-15R or 5-20R Receptacle)
Model 2216 requires a 120/240V 20A circuit
(50/60 Hz, 2 hot legs / 1 neutral leg, plus earth ground).
Circuit must be capable of 3500 Watts.

OPERATION
OPERATING INSTRUCTIONS
To over-ride the Brew
Wait mode, press and
hold the BREW key for
3 seconds when the
brewer is in Brew Wait
mode (i.e. when brew light
is flashing). The brew will
proceed immediately
regardless of water
temperature. This feature
should only be used when
testing water volume,
otherwise the brew will
proceed with the water
below the precise brew
temperature.
1. Energizing the Brewer: When electricity has been connected to
the unit, there will be a momentary flash of the power light. Turn
the brewer on by pressing the POWER key.
The brewer will start to fill the tank. With the
proper water supply the tank should be filled in
about 2½ minutes. Once filled, the heating
element will come on until the proper tank
temperature has been reached, (which will take
about 20 minutes on 120-Volt models or about
12 minutes on 120/240 Volt models).
2. Brewing (Precise Temperature for Brewing™ — PTB™): In the
regular operating mode, the E-Max™ LX maintains the tank
temperature within +/- 1ºF of the brew
temperature. Normally this will mean that a
brew will be started as soon as the BREW key
is pressed. However, there may be a slight
delay if the BREW key is pressed immediately
after a brew has been completed (notably on
120-volt models). If the tank temperature is
below the brew temperature, the brew will be
delayed, going into the “Brew Wait” mode, with
Note: the following
safety features have been
incorporated to prevent
multiple unattended
brews:
the brew light flashing. As soon as the correct
temperature is reached the brew will commence with the brew light on
continuously during the brew. When the brew begins the main warming
station will be turned on automatically (if it is not already on). During the
brew cycle, if the BREW key is pressed, it will be ignored. Only when
the brew is complete can another brew be started.
The brew key is in-
operative during a brew
cycle. This minimizes the
possibility of double
brewing.
3. Brew Cancel: To cancel a brew in progress, press the CANCEL
KEY: two beeps will sound and the “Brew” light
will go out. Water flowing to the brew chamber
will be stopped immediately, but if there is
already water in the brew chamber, it will take a
few moments before this drips through as
coffee.
When the “Brew” light is
on or flashing, repeated
pressing of the BREW
switch will be ignored,
(there will be a beep each
time it is pressed). A
Brew will only be activated
when the “Brew” light is
off.
4. Normal Operation (Non Brewing): When the unit is not brewing,
the E-Max™ LX maintains the water temperature at the Precise
Temperature for Brewing™ (PTB™). The heating element will
cycle on and off automatically to maintain this temperature.
5. After Hours Mode: If no brew is detected for a pre-selected length
of time, the brewer will enter the After Hours mode. Temperature
will be allowed to drop to save energy. Pressing the BREW KEY
returns the brewer to normal operation.

SERVICING INSTRUCTIONS — DE-LIMING HEATER TANK
CAUTION - CHEMICAL
BURN HAZARD
1. Disconnect brewer form the electrical supply. Turn off
the water supply and disconnect water supply from the
brewer inlet fitting.
De-liming chemicals are caustic.
Wear appropriate protective gloves
and goggles during this procedure.
Never siphon de-liming chemicals
or solutions by mouth.
This operation must only be
performed by qualified and
experienced service personnel.
2. Remove the top panel or top warmer section to gain
access to internal components.
3. Disconnect water level sensor and water temperature
sensor from the controller. On 120V units, slip hi-limit
thermostat from under its holder clip. Disassemble the
three lid clips and lift the lid off of the water tank. Store
lid assembly in a safe location.
4. Mix de-liming solution according to the manufacturer’s
directions. Add the de-liming solution to the water tank.
Set lid assembly back on tank. Allow to sit for 30
minutes, or as directed by the manufacturer.
IMPORTANT: DO NOT spill,
splash or pour water or de-liming
solution into or over any internal
component other than the inside of
the water tank.
5. At end of soaking period, remove lid assembly from tank.
Thoroughly rinse interior components of lid assembly
with clear water. Wipe temperature sensor and water
level sensor with a clean, soft cloth. Store lid assembly
in a safe location.
IMPORTANT: DO NOT allow any
internal components to come into
contact with the de-liming solution.
Take care to keep all internal
components dry.
6. Using a stiff bristle brush, scrub the coils of the heating
element and the interior surfaces of the water tank.
7. Siphon the used solution and loose lime/scale into an
appropriate container. Dispose of the used solution as
required by local ordinances.
NOTE: Repeat steps 4 thru 7 as
required to remove all scale and
lime build-up.
8. Fill the water tank with clean tap water. Rinse
thoroughly, then siphon the rinse water into an
appropriate container for disposal. Again, take care to
keep all internal components dry.
NOTE: Normally, silicone hoses
do not need to be de-limed.
9. Reassemble the tank lid to the water tank. Make sure
the gasket is properly attached to the lid before
assembling the lid clips. Re-connect the water level and
temperature probes, then reinstall the hi-limit thermostat
(if removed). Verify that all internal components are dry,
then reinstall the top panel.
Should de-liming hoses become
necessary, Bloomfield Industries
recommends replacing the hoses.
10. Reconnect brewer to water and electrical. Run and
discard at least three full decanters from the faucet.
Install the brew chamber without filter paper or grounds,
then run and discard at least three full decanters as
normal brew.
11. Brewer is ready to use.
