INSTALLATION INSTRUCTIONS

READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION

IMPORTANT:

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:

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.

CAUTION: Unstable
Equipment Hazard

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.

NOTE: Water supply inlet line
must mee t cer tain 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.

REFER TO EXPLODED VIEWS PAGES 16 thru 19 FOR
COMPONENT NAMES/NUMBERS

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.

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.

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.

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.

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.

4

INSTALLATION INSTRUCTIONS (continued)

Y

4. 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.

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.

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.

ELECTRICIAN’S INSTALLATION INSTRUCTIONS

REFER TO ELECTRICAL SPECIFICATIONS - Page 1
Check the nameplate to determine correct electrical service

required for the Brewer to be installed.

OPERATION

SEE PAGE 13 FOR COMPONENT NAMES/NUMBERS

1. Water enters at the inlet fitting of the fill solenoid (32). The
solenoid admits water via a command from the controller.

NOTE: The solenoid has an internal strainer. To clean the
strainer: Shut off water supply. Unscrew the plastic cap
protruding from the rear of the brewer. Remove the cap,
inlet fitting and washer. With pliers, grasp the bar of the
strainer and pull straight out. Wash any debris from the
strainer. Note orientation - DO NOT reverse strainer.
Reassemble and reinstall. Turn water supply back on.

2. Water enters the tank (2) thru the fill tube (16). Water is
heated in the tank by the heating element (15).

3. The tank lid (9) is sealed around the edge with a gasket
(6), and is secured by 3 clips (10).

4. Heated water is dispensed to the brew head through the
brew tube (14), brew solenoid (18), and spout of the brew
fitting (19). The brew solenoid is energized during the brew
cycle by the controller.

NOTE: The flow rate of the brew solenoid is factory set.
DO NOT adjust.

5. Hot water is sprayed over the coffee grounds by the spray

disc (24), which is sealed to the brew head by a gasket (23).

6. The tank is vented through the vent fitting (40) and vent

tubes (12 & 13).

7. Water for the hot water faucet (22) is supplied from the tank

through the faucet supply tube (11).

SERVICING INSTRUCTIONS — DE-LIMING HEATER TANK

CAUTION - CHEMICAL
BURN HAZARD

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.

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.

IMPORTANT: DO NOT allow any
internal components to come into
contact with the de-liming solution.
Take care to keep all internal
components dry.

NOTE: Repeat steps 4 thru 7 as
required to remove all scale and
lime build-up.

NOTE: Normally, silicone hoses
do not need to be de-limed.
Should de-liming hoses become
necessary, Bloomfield Industries
recommends replacing the hoses.

1. Disconnect brewer form the electrical sup ply. Turn off

the water supply and disconnect water supply from the
brewer inlet fitting.

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.

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.

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.

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.

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.

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.

SERVICING INSTRUCTIONS — DIAGNOSTICS & TROUBLESHOOTING)

If the E-Max™ LX goes into an error mode as outlined below, it
will probably be necessary to reset the brewer in order to test
individual components. Note the reset procedure below:
* FOR “LOW WATER” OR “OVERHEAT” ERRORS:
PRESS & HOLD CANCEL FOR 3 SECONDS, OR
RE-ENERGIZE THE BREWER (i.e. unplug for a few
seconds, the plug in again.)

* FROM “VALVE FAULT” ERROR: THE BREWER MUST
BE RE-ENERGIZED Using the CANCEL button will not
reset the brewer from “Valve Fault”.

ERROR
LOW WATER TEMP

(Not an error)

LOW WATER LEVEL:

Inlet valve has been on
and no water sensed:
a. During regular

operation for 60
sec., or

b. during startup for

4-1/2 min.

VALVE FAULT:
Detection of a problem
with the wiring to the
valve or of the valve
switching system.

OVERHEAT:

Water temperature has
exceeded 210ºF

POSSIBLE PROBLEM & CORRECTIVE ACTION

1. Water has not reached Precise Temperature
for Brewing™. WAIT UNTIL WATER
TEMPERATURE HAS RECOVERED.

1. Sleeve on level sensing probe gasket is too
long or sensor not pushed down fully. Sensor
should protrude beyond sleeve 1/4”.
REMOVE TANK LID, CUT SLEEVE TO
PROPER LENGTH. MAKE SURE SENSOR
IS FULLY PUSHED DOWN.

2. Level sensor may be pulled out of tank.
REINSTALL SENSOR.

3. Wiring to sensor may be disconnected or
faulty. REPAIR WIRING

4. Level sensor may be encrusted with scale or
lime build-up. CLEAN SENSOR (use chemical
de-liming. Scraping or sanding will damage
the sensor.

5. Water supply may be shut off, or is incapable
of filling the tank in the allotted time.
RESTORE WATER SUPPLY.

1. Wiring to either inlet or dump valve not properly
connected. CHECK WIRING / CONNECTORS.

2. Controller has two switches for each valve, one
or both has been detected as failing on.
REPLACE CONTROL BOARD.

1. Brew temperature may be too close to max.
temp. Brew temperature should be no higher
than 205ºF. LOWER BREW TEMPERATURE
SETTING.

2. Triac may have failed on, and water continues
to heat even after controller has tried to turn
heating element off. CHECK TRIAC,
REPLACE IF REQUIRED.

3. Probe may be defective. TEST ACTUAL
TEMPERATURE TO VERIFY. REPLACE
PROBE OR REPAIR WIRING AS REQUIRED.

IMPORTANT: The following
troubleshooting suggestions are for
operator reference only.
