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 mini m u m
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.
UNPACKING & INITIAL INSPECTION
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) Verify that the Spray Head and Spray Head
Gasket 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. 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.
4
INSTALLATION INSTRUCTIONS (continued)
For ‘Filter-Ready” units, refer to filter installation and hook-up
instructions packed with the brewer.
5. NSF requires that the brewer be able to be moved for
cleaning underneath. 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.
NOTE: Models 2080 & 2082 require a 115 - 125 V 15A circuit
(50/60 Hz, 2 wire plus earth ground, with
NEMA 5-15R or 5-20R Receptacle)
Models 2086 & 2088 require a 120/240V 20A circuit

OPERATION
OPERATING INSTRUCTIONS
IMPORTANT:
All E-Max™ brewers are
tested and set at the factory
If programming adjustments are necessary,
refer to the E-Max™
Programming Manual
(p/n/73674).
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.
Note: the following
safety features have been
incorporated to prevent
multiple unattended
brews:
The brew key is disabled
during a brew cycle. This
minimizes the possibility
of double brewing.
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.
.
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™ 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 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.
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.
4. Normal Operation (Non Brewing): When the unit is not brewing,
the E-Max™ 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.
