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.

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,
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.

Plumber must provide two 1/4” female are 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 ow thru the

valve.

WARNING

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.

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 gure 3 at right.

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 lled with water.

Pour water into each pour-over

opening until water ows 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.

IMPORTANT: Wiring must be installed in approved solid or

exible conduit, and must be secured to the brewer with a strain

relief (to be provided by the installer).

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.

START-UP

A.IMPORTANT:

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 ows 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.
