EqUIPMENT
HAzARD
It is very important for safety
and for proper operation that the
brewer is level and stable when
standing in its nal 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 meet certain minimum
criteria to insure successful
operation of the brewer.
Bloomeld 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.
Unpack the unit. Inspect all components for completeness and
condition. Ensure that all packing materials have been removed
from the unit.
Verify that the Spray Head Gasket and Spray Disk are properly
installed.
LEVELING THE UNIT
Verify that an adjustable leg is installed at each corner of the
brewer.
Set Brewer in its operating location. 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.
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
IMPORTANT:
This equipment must be installed to comply with all appli-
cable federal, state and local plumbing codes and ordinances;
specically:
The Basic Plumbing Code of Building Ofcials and Code
Administrators International, Inc. (BOCA) and the Food Service
Sanitation Manual of the Food and Drug Administration (FDA).
Brewer should be connected to a POTABLE WATER, COLD WATER line. Flush water line before connecting to Brewer.
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 ush the line prior to installing the saddle.
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.
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 ow thru the
valve.
The water line must terminate in a 1/4” male are tting, which
will connect to the provided ex line. See Figure 2 below.
Fig. 2 Water Supply Installation
In some areas, local codes require a backow preventer (check
valve) to be installed on the inlet water line. If a backow
preventer is used, you must install a water hammer arrester in the
incoming line, between the backow 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.
IMPORTANT: Before connecting to electricity, make sure
automatic brewers are connected to the water supply.
Model 1016BVM is equipped with a cord and twist-lock plug.
It requires a 120/240 volt 30 amp circuit (50/60 Hz, 3 wire plus
ground, with NEMA L14-20R Twist-Lock Receptacle).
WARNING:
ELECTRIC SHOCK
HAzARD
Brewer must be properly
grounded to prevent possible
shock hazard. DO NOT
assume a plumbing line
will provide such a ground.
Electrical shock will cause death
or serious injury.
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.
IMPORTANT: Do not connect
brewer to electrical power until
you are ready to ll the tank.
See instructions on page 6.
IMPORTANT: The ground
prong of the plug is part of a
system designed to protect
you from electrical shock in
the event of internal dam-
age. Never cut off the ground
prong nor twist a blade to t an
existing receptacle. Contact a
licensed electrician to install the
proper circuit and receptacle.
Tank must be full of water
before pressing POWER
key “on”. Heating
elements will be damaged
if allowed to operate
without being fully
submerged in water.
Damage caused by
operating the brewer
without water in the tank
is NOT COVERED BY
WARRANTY.
START-UP
A.
For initial start-up, or if the brewer has not been used for an
extended period of time:
• Be sure spray disk and brew gasket are properly installed in the
brew head.
• Be sure the water supply is properly connected and the water supply
valve is turned ON.
• Be sure the WATER TANK IS FILLED.
IMPORTANT: Fill the water tank before energizing this unit:
Insert the brew chamber (empty) and place an EMPTY decanter in
1.
place under the brew chamber.
Connect unit to electric power. Four beeps will sound and all lights
2.
glow momentarily.\
Be sure the brewer is “off” (if necessary, press ON/OFF key until
3.
no LEDs are lit).
Press BREW key three (3) times, then press CANCEL key once.
4.
BREW and HEAT indicators will ash while tank is lling.
When water starts to ow from the brew chamber, the tank is full.
5.
Press ON/OFF key once to terminate ll. Heating element will be
energized and will begin heating water in preparation for the rst
brew. When the water has reached the proper temperature, the
HEAT light will go out.
Water temperature is sensed by an electronic
water temperature probe inserted into the
water tank. This temperature signal is fed to
the controller.
The setpoint temperature is adjustable. The
controller sends a command signal to the
power board based upon a comparison
between the setpoint temperature and actual
temperature. See page 15.
The power board energizes the heating
elements based on the command signal from
the controller.
Excessive temperature will trip the hi-limit
safety switch. When the brewer cools,
remove front panel and press the red button
on the hi-limit to reset.
WATER FLOW
AUTOMATIC OPERATION
Pressing the BREW key energizes the
solenoid valve, allowing water from an
external water supply to ow into the water
tank. The incoming water forces heated
water out of the tank to perform the brew.
The solenoid uses a ow control device so
that ow is consistent between 20 p.s.i. and
90 p.s.i.
The length of time the solenoid is open
is controlled by the time setting of the
controller. See page 16.
After the solenoid closes, water will continue
to ow to the brew chamber until water level
in the tank falls below the brew pickup,
breaking the siphon.

HOT WATER FAUCET
The faucet water coil is submerged in the
hot water tank and draws heat from the brew
water. Water going to the water coil is not
controlled by the solenoid valve.
brewer until the water
tank has been lled. Dry

ELECTRONIC FEATURES
Energizing the Brewer
When electric power is applied to the unit, all the indicators will glow
momentarily and four beeps will sound. The unit will be off.
Press the ON/OFF key. Five beeps will sound and the POWER
indicator will remain on. If the water temperature is below setpoint,
HEAT indicator will glow until water temperature reaches setpoint.
Press the ON/OFF key again to turn the brewer off. Four beeps will
sound, the tank heater and all warmers will be switched off, and all
indicator lights will go out.
Brew Settings
See pages 17 & 18 for setting Brew Time and Temperature.
ABS™ (Automatic Brew Start)
Start a brew by pressing BREW. A single beep will sound. The system
will verify that the water in the tank is at the proper temperature. If it is,
brew will start immediately. Otherwise, the BREW indicator will ash
(Brew Waiting Mode) until the water reaches setpoint temperature,
then the indicator will glow and brew will commence. If the main
warmer is off, it will be energized automatically.
At the conclusion of the brew cycle, three beeps will sound.
NOTE: To override Brew Waiting Mode, press and hold the BREW key
for 3 seconds while the BREW indicator is ashing. Brew will begin
regardless of water temperature. To avoid under-temperature brews,
this feature should only be used when setting brew volumes.
multiple, unattended brews. While the BREW indicator is on or
ashing, any additional strokes of the BREW key will be ignored (there
will be a beep each time the key is pressed, however). Another brew
cannot be initiated until the previous brew is complete.
The Brew Waiting Time, also called Dripout Time, (interval between
when the brew is completed and the audible signal sounds at the
end of the brew) may be adjusted between 2 and 8 minutes at the
Brew Signal Timer dial on the controller. This allows all water in brew
chamber to drip through as coffee. See page 18.
Brew Cancel
To cancel a brew in progress or a brew in waiting, press the CANCEL
key. Two beeps will sound and the BREW indicator will go out.
NOTE: If a brew in progress is cancelled, coffee will continue to ow
until all water delivered has dripped through the brew chamber.
Coffee looses its freshness as it sits on a warmer. The Quality Timer
ashes the warmer lights 30 minutes after the last brew to remind you
that the coffee is nearing the end of its useful life.
After Hours™ Operation
During normal operation, the controller will maintain the precise
brewing temperature. If, however, if the BREW key in not pressed for
3 hours, the brewer goes into After Hours™ mode; any warmer left on
will be turned off; and, the temperature will only be maintained to within
20ºF. This feature prolongs component life and saves energy.
As soon as the BREW key is pressed, the brewer returns to normal
operation, heating the water to the precise temperature before
beginning the brew. The brewer will return to After Hours™ mode only
if three hours pass without a brew being initiated.
Disable/Enable After Hours™ Feature
To disable After Hours™, press the ON/OFF key to turn the brewer off.
Press and hold the CANCEL key until two beeps sound, and the HEAT
indicator ashes twice. This feature is now disabled.
To re-enable After Hours™, press the ON/OFF key to turn the brewer
off. Press and hold the CANCEL key until three beeps sound, and the
POWER indicator ashes twice. This feature is now enabled, however,
it will not be activated unless no brew is initiated for three hours.
After Hours™ is an energy
saving feature. The
brewer will enter After
Hours™ mode if it is not
used for three hours.
Press the BREW key
to immediately return
the brewer to normal
operation.
Over-Temperature and Temperature Fault Protection
Should the water temperature exceed 214ºF (101ºC), or if the controller
does not detect a 2ºF (1ºC) rise in temperature within four minutes of
calling for heat, the brewer will go into Over Temperature Mode; the
heating element is turned off, all warmers are disabled and all lights will
ash.
Possible causes of Over Temperature condition:
Setpoint is in the boiling range.
•
Insufcient water volume to prevent water in tank from boiling
•
during brew.
Heating element or temperature probe has malfunctioned.
•
Excessive scale buildup is preventing the element from heating the
•
water.
Heating element relay fails in the “on” state.
•

and Dripout Time
IMPORTANT: Before set-
ting assembly into tank, make
sure tank lid gasket is properly
seated on ange of lid.
IMPORTANT: When replac-
ing temperature probe, be sure
a new seal washer is in place
around the probe. Tighten jamb
lock nut only enough to ensure
no water leakage. Excessive
tightening is not necessary.
BREW TIME ADJUSTMENT
The amount of water dispensed automatically during a brew cycle
is controlled by the SOLENOID TIME dial of the controller.
Place empty decanter under brew chamber. Press BREW
button. Brewer should dispense one full decanter of water. To
adjust amount:
Remove brew chamber and button plug. On the controller, adjust
SOLENOID TIME dial (BREW TIME); clockwise increases time.
Run several cycles to check amount of water delivered.
DRIPOUT TIME ADJUSTMENT
Water delivered to the brew chamber will take a while to drip
through as coffee. The time between the end of a brew and
when a new brew can be initiated is controlled by the BREW
SIGNAL TIMER. Adjust the BREW SIGNAL TIMER dial on the
controller to account for the dripout time. Replace button plug.
