INSTALLATION

READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
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.
PLUMBER’S INSTALLATION INSTRUCTIONS
Brewer must 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 Figure 2 below.
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.
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.
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:
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.
IMPORTANT: Do not connect
brewer to electrical power until
you are ready to ll the tank.
See instructions at left.
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 8740 is equipped with a cord and plug.
It requires a 115 - 125 volt 20 amp circuit (50/60 Hz, 2 wire plus
ground, with NEMA 5-15R receptacle).
PREPARATION
The water tank must be ller prior to operation. Slide an empty
brew chamber in place under the brew head. Place an empty
dispenser under the brew chamber.
Be sure the unit is connected to the water supply, the water
supply is turned ON and the “TANK HEATER SWITCH” is OFF.
Connect the unit to electric power.
Press the “START BREW” switch to initiate a brew cycle. The
solenoid will open and begin lling the tank. Initiate consecutive
brew cycles until water begins to ow from the brew head.
When all water stops dripping, discard all water generated.
Press the “TANK HEATER SWITCH” to ON. The heating
elements will begin heating the water in the tank. When the
“READY TO BREW” light glows the unit is ready for use. Fig. 3 Plug Conguration

OPERATION
Fig. 4 Brewer Operation Diagram
A. START-UP
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:
1. Insert the brew chamber (empty) and place an empty dispenser in
place under the brew chamber.
2. Be sure the TANK HEATER SWITCH is “off”. Plug the unit into an
appropriate receptacle.
3. Press The BREW switch. Water will start lling the tank. Run
several consecutive brew cycles until water ows from the brew
chamber.
4. When water stops dripping from the brew chamber, empty the
dispenser, then press TANK HEAT switch “on”. The heating
element will begin heating water in the tank. When the water has
reached the proper brewing temperature, the “READY TO BREW”
light will glow.
IMPORTANT:
Tank must be full of water
before pressing TANK
HEATER SWITCH “on”.
Heating elements will be
damaged if allowed to
operate without being
fully submerged in water.
Damage caused by

OPERATION (continued)
WATER HEATER
Water temperature is sensed by a thermobulb
inserted into the water tank. This temperature
signal is fed to the mechanical thermostat.
The temperature setpoint is adjustable. Heating
element is energized by the thermostat.
Excessive temperature will trip the hi-limit safety
switch. The hi-limit will automatically reset when
the brewer cools.
WATER FLOW
AUTOMATIC OPERATION
Pressing the BREW switch starts the timer, which
in turn energizes the solenoid valves. This allows
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.
Additionally, a measured amount of unheated
water is bypassed into the dispenser to dilute and
cool 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 timer setting.

A. PREPARATION
Place one (1) genuine Bloomeld
paper lter into the brew chamber.
Add an amount of fresh tea leaves
to the brew chamber appropriate
to the brew volume.
NOTE: the brewer can brew any
volume between 3 and 5 gallons,
and is factory set for a 3 gallons
brew volume. If other brew
volumes are desired, refer to
SOLENOID TIME ADJUSTMENT,
page 13.
Gently shake the brew chamber to level the bed of tea leaves.
Slide the brew chamber into place under the brew head.
B. AUTOMATIC OPERATION
BE sure “READY TO BREW” light is lit.
Place the appropriate EMPTY dispenser in place under the brew
chamber. If a brew-thru lid is used, be sure the bypass opening in
the lid is directly under the bypass nozzle.
Press the “BREW” switch. The brew solenoid will open for
an amount of time determined by the timer setting, admitting a
measured quantity of water into the tank.
Inlet water will displace a like amount of heated water from the tank.
The hot water will be forced into the brew head where it will spray
over the bed of grounds. Freshly brewed tea will begin to ll the
dispenser. Additionally, a measured amount of cold dilution water
will ow from the bypass nozzle into the dispenser.
When the ow and all dripping stops at the end of the brew cycle,
the tea is ready to serve.
Discard the contents of the brew chamber and rinse it in a sink.
When the ”READY TO BREW” light glows, the brewer is ready for
another brew cycle.
CAUTION:
BURN HAZARD
Exposed surfaces of the
brewer, brew chamber and
dispenser may be HOT to
the touch, and can cause
serious burns.
CAUTION:
BURN HAZARD
To avoid splashing or
overowing hot liquids,
ALWAYS place an empty
dispenser under the brew
chamber before starting
the brew cycle. Failure to
comply can cause serious
burns.
CAUTION:
BURN HAZARD
After a brew cycle, brew
chamber contents are
HOT. Remove the brew
chamber and dispose of
used tea leaves with care.
Failure to comply can
cause serious burns.
