CAUTION:
UNSTABLE
PLUMBER’S INSTALLATION INSTRUCTIONS
EQUIPMENT HAZARD
Brewer should be connected to a POTABLE WATER, COLD
WATER line. Flush water line before connecting to Brewer.
DO NOT operate brewer unless
factory supplied adjustable legs
are installed and properly
adjusted.
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.
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
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.
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.
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.
4
INSTALLATION (continued)
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.
NOTE: This equipment must be
installed to comply with
applicable federal, state and
local plumbing codes and
ordinances.
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.
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.
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.
IMPORTANT:
Do not connect brewer to
electrical power until you are
ready to fill the tank. See
instructions on page 6.
ELECTRICIAN’S INSTALLATION INSTRUCTIONS
REFER TO ELECTRICAL SPECIFICATIONS - Page 1
Check the nameplate to determine correct electrical service
required for this installation.
IMPORTANT: Before connecting to electricity, make sure the
brewer is connected to the water supply.
IMPORTANT:
For power supply connections use COPPER WIRE only. Wiring
must be suitable for at least 75ºC. This brewer requires a
dedicated electric circuit.
Models 8752 must be wired by an electrician, and require a
115/230V 20A circuit (50/60 Hz, 2 hot legs / 1 neutral leg, plus
ground). Remove rear 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
relief (to be provided by the installer).

OPERATION
Fig. 4 Brewer Operation Diagram
IMPORTANT:
START-UP
For initial start-up, or if the brewer has not been used for an
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
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.
operating the brewer
without water in the tank
is NOT COVERED BY
WARRANTY.
♦ Be sure the WATER TANK IS FILLED
BEFORE connecting brewer to electrical power THE WATER TANK
MUST BE FILLED. Place an empty decanter under the brew head.
Lift the pour-over cover then pour warm tap water into the pour-over
opening until water flows from the brew head. When water stops
dripping from the brew head, 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 will begin heating the water in the tank. When the water
has reached the proper temperature, the READY TO BREW light
will glow.
6
OPERATION (continued)
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.
Fig. 5 Heat Control Diagram
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
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.
The faucet is at supply water pressure any
time the faucet shut-off valve is OPEN.

CAUTION:
BURN HAZARD
B. POUR-OVER OPERATION
To avoid splashing or
overflowing hot liquids,
ALWAYS place an empty
decanter under the brew
chamber before starting
the brew cycle. Failure to
comply can cause serious
burns.
NOTE: Any Integrity™ brewer can be used in the pour-over mode.
BE sure “READY TO BREW” light is lit.
Place the appropriate EMPTY decanter in place under the brew
chamber.
Fill a decanter with tap water. Lift the pour-over cover and pour the
entire contents of the decanter into the pour-over opening, which
will fill the basin.
Water from the basin 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 coffee
will begin to fill the container under the brew chamber. When the
flow and all dripping stops, the coffee is ready to serve.
CAUTION:
BURN HAZARD
After a brew cycle, brew
chamber contents are
HOT. Remove the brew
chamber and dispose of
used grounds with care.
Failure to comply can
cause serious burns.
Discard the contents of the brew chamber. Rinse the brew
chamber in a sink. When the ”HEAT” light goes out, the brewer is
ready for another brew cycle.
C. AUTOMATIC OPERATION
BE sure “READY TO BREW” light is lit.
Place the appropriate EMPTY decanter in place under the brew
chamber.
Press the “BREW” switch. The 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 coffee will begin to fill the
container under the brew chamber.
NOTE: Water for the hot
water faucet is heated in a
coil inside of the water
tank. Use of the faucet will
not affect the volume of
water delivered for a brew.
However, overuse of the
faucet during a brew may
lower the temperature of
the brew water.
When the flow and all dripping stops, the coffee 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.
