INSTALLATION INSTRUCTIONS  
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION  
IMPORTANT:  
REFER TO EXPLODED VIEWS PAGES 18 thru 21 FOR  
COMPONENT NAMES/NUMBERS  
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:  
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.  
CAUTION: Equipment  
Electrical Damage  
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.  
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.  
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.  
CAUTION: Unstable  
Equipment Hazard  
PLUMBER’S INSTALLATION INSTRUCTIONS (AUTOMATIC  
BREWERS ONLY)  
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.  
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 10 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 25 feet and 3/8" for  
more than 25 feet from a 1/2"  
water supply line.  
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.  
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 Fig. 2 at right.

INSTALLATION INSTRUCTIONS (continued)  
NOTE: This equipment must be  
installed to comply with all  
applicable federal, state and  
local plumbing codes and  
ordinances.  
WARNING ELECTRIC  
SHOCK HAZARD:  
Brewer must be properly  
grounded to prevent possible  
Fig. 2 Water Supply Installation  
shock hazard. DO NOT  
assume a plumbing line will  
provide such a ground.  
Electrical shock will cause death  
or serious injury.  
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  
the tank is filled with water.  
Pour water into the pour-over  
opening until water flows from  
the brew head.  
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:  
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: Before connecting to electricity, make sure  
automatic brewers are connected to the water supply.  
Models 8778, 8780, 8782, 8783 & 8785 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).  
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 fit an existing receptacle. Contact a licensed electrician  
to install the proper circuit and receptacle.  
Models 8786 & 8788 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 front panel to gain access to terminal  
block. Green terminal must be connected to a suitable building  
ground. Circuit must be capable of 3500 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:  
A. START-UP  
Tank must be full of water  
before connecting brewer  
to electrical power.  
For initial start-up, or if the brewer has not been used for an  
extended period of time:  
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 tank  
is NOT COVERED BY  
WARRANTY.  
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 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. 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.

OPERATION (continued)  
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.

chamber in a sink. When the ”READY TO BREW” light glows, the  
brewer is ready for another brew cycle.  
C. AUTOMATIC OPERATION  
NOTE:  
BE sure “READY TO BREW” light is lit.  
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. Draw no  
more than one (1) cup of  
water at a time.  
Place the appropriate EMPTY airpot or thermal server 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 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.  
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
