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 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 meet certain 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 18 - 21 FOR
COMPONENT NAMES/NUMBERS

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, and that a rubber foot is installed on each leg.

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 flush 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.

Plumber must provide two 1/4” female flare water supplies for this
brewer.

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.

625 75873 Owners Manual Gourmet 1000 Dual Airpot Brewers

INSTALLATION INSTRUCTIONS (continued)

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. See Figure 2 below.

Fig. 2 Water Supply Installation

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

IMPORTANT: Before connecting to electricity, make sure
automatic brewers are connected to the water supply.

Gourmet 1000™ dual brewers must be wired by an electrician.
Model 8792 requires a 120/240V 20A circuit (50/60 Hz, L1, L2,
Neut. plus Ground).

Remove front panel to gain access to terminal block. Green
terminal must be connected to a suitable building ground. Circuit
must be capable of 4000 Watts. See figure 3 at right.

IMPORTANT: Wiring must be installed in approved solid or
flexible conduit, and must be secured to the brewer with a strain

625 75873 Owners Manual Gourmet 1000 Dual Airpot Brewers

relief (to be provided by the installer).

NOTE: This equipment must be
installed to comply with
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
both tanks are filled with water.
Pour water into each pour-over
opening until water flows from
the respective 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

Fig. 4 Brewer Operation Diagram

IMPORTANT:

Tanks must be full of
water before connecting
brewer to electrical power.
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 tanks
is NOT COVERED BY
WARRANTY.

A. START-UP

For initial start-up, or if the brewer has not been used for an
extended period of time:

Be sure spray disks and brew gaskets are properly installed in both
brew heads.

Be sure the water supply is properly connected and the water
supply valve is turned ON.

BEFORE plugging the brewer into a receptacle, or otherwise
connecting brewer to electrical power THE WATER TANKS MUST
BE FILLED. Place an empty container under each brew head. Lift
the pour-over covers and pour tap water into the pour-over
openings until water flows from both brew heads. When water stops
dripping from the brew heads, empty the containers. This will
require about 3 full 64 oz. decanters of water per side.

Once both tanks are full of water, connect the brewer to electrical
power. The heating elements will begin heating the water in the
tank. When the water has reached the proper temperature, the
“READY TO BREW” light will glow.

625 75873 Owners Manual Gourmet 1000 Dual Airpot Brewers

WATER HEATER

Water temperature is sensed by a
thermobulb inserted into the water tank. This
temperature signal is fed to the thermostat,
which controls line power to the heating
element.

The setpoint temperature is adjustable at the
thermostat.

The element is protected from over­temperature by a hi-limit thermostat.

WATER FLOW

POUR-OVER FEATURE

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

AUTOMATIC OPERATION
Pressing BREW button energizes the

solenoid valve, allowing water from an
external water supply to flow into the basin
pan and then into the hot water tank. This
forces an identical amount of hot water out
of the tank and through the spray head into
the brew chamber

The solenoid uses a flow control device so
that flow is consistent between 20 p.s.i. and
90 p.s.i.

Length of time the solenoid is open is
controlled by the timer.

HOT WATER FAUCET (RIGHT SIDE)
The faucet water coil is submerged in the

right side hot water tank, and draws heat
from the brew water. Water going to the
water coil is not controlled by the solenoid
valve.

Hot water is provided at the faucet, at supply

625 75873 Owners Manual Gourmet 1000 Dual Airpot Brewers

water pressure, any time the faucet shut-off
valve is OPEN.
