INSTALLATION
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.
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.
REFER TO EXPLODED VIEWS PAGES 18 thru 22 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 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
IMPORTANT: This equipment must be installed to comply
with all applicable federal, state and local plumbing codes and
ordinances; specically:
The Basic Plumbing Code of Building Ofcials and Code
Administrators International, Inc. (BOCA) and the Food Service
Sanitation Manual of the Food and Drug Administration (FDA).
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.
913 p/n 2M-75937 Owners Manual 8718, 8738 Coffee Brewer

INSTALLATION (continued)
The water line must terminate in a 3/8” MNTP quick-disconnect
tting, which will connect to the provided ex line. See Figure 2
below.
Fig. 2 Water Supply Installation
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.
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
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

OPERATION
Fig. 4 Brewer Operation Diagram
IMPORTANT:
Tank 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 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.
• Be sure the water supply is properly connected and the water supply
valve is turned ON.
• Be sure the WATER T
BEFORE energizing the tank heater ThE WaTER TaNk MuST
BE FIllED. Place an empty decanter under the brew head. With
the TANK HEATER SWITCH OFF, press the START BREW
SWITCH. Run at least three full brew cycles, or until water
ows from the brew head. When water stops dripping, empty the
container.

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.
WATER FLOW
AUTOMATIC OPERATION
Pressing BREW button energizes the
solenoid valve, allowing water from
anexternal 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.
Fig. 5 heat Control Diagram
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.
