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 16.) 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.  
WARNING ELECTRIC

SUPPLY  
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.  
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:  
Before connecting to electricity,  
make sure the E-Max™ LX has  
been properly connected to the  
water supply.  
ELECTRICIAN’S INSTALLATION INSTRUCTIONS  
REFER TO ELECTRICAL SPECIFICATIONS - Page 1  
IMPORTANT:  
Check the nameplate to determine correct electrical service  
required for the Brewer to be installed.  
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 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.  
Wipe temperature sensor and water level sensor with a  
clean, soft cloth. Thoroughly rinse interior components  
of lid assembly with clear water. 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 servers as normal  
brew.  
11. Brewer is ready to use.
