INSTALLATION INSTRUCTIONS
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
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.
IMPORTANT:
This equipment must be installed
to comply with all applicable
federal, state and local plumbing
codes and ordinances.
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 25 feet and 3/8” for
more than 25 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, 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 (MODEL 8773
BREWERS ONLY)
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.
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 Fig. 2 at right.

INSTALLATION INSTRUCTIONS (continued)
IL1596
Fig. 2 Water Supply Installation - New-Style Brewers
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.
Domestic models 8773 & 8774 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 receptacle).
Export models 8773 & 8774 are equipped with a cord and plug.
Refer to page 1 for circuit voltage requirements.
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.
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.

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.
For automatic brewers, 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 TANK MUST
BE FILLED. Place an empty container under the brew head. Lift
the pour-over cover then pour three decanters of warm tap water
into the pour-over opening. Water will begin to ow from the brew
head. When all water ow stops, empty the container.
Once the tank is full of water, connect the brewer to electrical
power. Press the tank heater switch to ON. The heating elements

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 over-temperature by a hi-limit thermostat.
To save energy, press the TANK HEAT switch
to OFF if no brew is expected for an
extended period.
WATER FLOW
POUR-OVER FEATURE (8773 & 8774)
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.
Fig. 5 Heat Control Diagram
AUTOMATIC OPERATION (8773 only)
Pressing BREW button energizes the
solenoid valve, allowing water from an
external water supply to ow 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 ow control device so
that ow 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 (8773 only)
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.
Hot water is provided at the faucet, at supply
water pressure, any time the faucet shut-off
valve is OPEN.
