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 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 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.

Bloomeld 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 (#33) and Spray Disk (#34)
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
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 provided water line strainer must be installed in the supply

line, between the shutoff valve and inlet tting. Note FLOW

arrow marking on strainer body.

NSF requires that the brewer be able to be moved for cleaning

underneath. A ex line or loops of copper tubing will satisfy this

requirement. See Figure 2 below.

Fig. 2 Water Supply Installation

In some areas, local codes require a backow preventer (check
valve) to be installed on the inlet water line. If a backow

preventer is used, you must install a water hammer arrester

in the incoming line, between the backow 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.

Models 1012, 1040 & 1072 are equipped with a cord and plug.
They require a 115 - 125 volt 15 amp circuit (50/60 Hz, 2 wire
plus ground, with NEMA 5-15R or 5-20R Receptacle).

IMPORTANT: The ground prong of the plug is part of a system
designed to protect you from electrical shock in the event of
internal damage. 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.

NOTE: This equipment must
be installed to comply with
all applicable federal, state
and local plumbing codes and
ordinances.

WARNING:

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: Do not connect
brewer to electrical power until

the tank is lled with water.

Pour water into the pour-over

opening until water ows from

the brew head.

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.

OPERATION (continued)

WATER hEATER

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 17.

The power board energizes the heating elements
based on the command signal from the controller.

Excessive temperature will trip the hi-limit safety
switch. The hi-limit will automatically reset when
the brewer cools.

WATER FLOW

POUR-OVER FEATURE

Pouring any amount of water into the pour-over
opening and into the basin pan forces an identical
amount of heated water out of the tank and through
the spray head.

Fig. 5 heat Control Diagram

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 18.

After the solenoid closes, water will continue to ow

to the brew chamber until the water level in the tank
falls below the brew pickup, breaking the siphon.

OT 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.

NOTE: Brew Waiting Mode (BREW indicator ashing) prevents

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 initiated 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. See page 18.

OPERATION (continued)

Quality Timer

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.

Quality Timer is normally
set for 30 minutes. It can
be set for 20 minutes by
moving a jumper on the
controller. See page 17.

After Hours™ is an energy
saving feature. The brew­er will enter After Hours™
mode if it is not used for
three hours.
