WARNING: ELECTRIC SHOCK HAZARD
All servicing requiring access to non-insulated components must be performed by qualified
service personnel. Do not open any access panels which require the use of tools.
Failure to heed this warning can result in electrical shock.
WARNING: INJURY HAZARD
All installation procedures must be performed by qualified personnel with full knowledge of all
applicable electrical and plumbing codes. Failure could result in property damage and
personal injury.
WARNING: ELECTRIC SHOCK HAZARD
Dispenser 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.
WARNING: BURN HAZARD
This appliance dispenses very hot liquid. Serious bodily injury from scalding can occur from
contact with dispensed liquids.
This appliance is intended for commercial use only.
This appliance is intended for use to dispense hot water for
human consumption. No other use is recommended or
authorized by the manufacturer or its agents.
The following trouble shooting, component views and parts lists
are included for general reference, and are intended for use by
qualified service personnel.
This manual should be considered a permanent part of this

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.
LEVELING THE UNIT
Set Dispenser on a solid level surface.
Be sure all four feet touch the counter to prevent tipping.
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:
ELECTRICAL
DAMAGE
DO NOT plug in or energize this
appliance until all Installation
Instructions are read and
followed. Damage to the
Dispenser 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 final
operating position. Failure to
provide a stable, level counter
for the dispenser will result in
movement of the dispenser
which can cause personal
injury and/or property damage.

INSTALLATION (continued)

READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
PLUMBER’S INSTALLATION INSTRUCTIONS
Dispenser should be connected to a POTABLE WATER, COLD
WATER line. Flush water line before connecting to Dispenser.
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 Dispenser 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 flow thru the
valve.
NSF requires that the Dispenser be able to be moved for
cleaning underneath. Loops of copper tubing will satisfy this
requirement. See Figure 2 below.
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
Dispenser water inlet, as far away from the Dispenser as space
will allow. This will relieve the excessive back pressures that
can cause leaks and solenoid malfunctions.
CAUTION:
ELECTRICAL
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.
IMPORTANT:
Tank must be full of water
before connecting dispenser to
electric power. Heating
elements will be damaged if
allowed to operate without
being fully submerged in water.
See instructions for filling tank,
page 7.
Damage caused by operating
the dispenser without water in
the tank is NOT COVERED BY
WARRANTY.
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.
NOTE: This equipment must be
installed to comply with
applicable federal, state and
local plumbing codes and
ordinances.

ELECTRICIAN’S INSTALLATION INSTRUCTIONS
REFER TO ELECTRICAL SPECIFICATIONS - Page 1
Check the nameplate to determine correct electrical service
required for the Dispenser to be installed.
IMPORTANT: Before connecting to electricity, make sure
Dispenser is connected to the water supply.
Dispenser is equipped with a cord and plug. It will require a
115 - 125 volt 20 amp circuit (50/60 Hz, 2 wire plus ground,
with NEMA 5-15R Receptacle).
See Figure 3 at left.
WARNING:
SHOCK HAZARD
Dispenser 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
Dispenser or result in de-
creased performance. Such
damage is not covered by war-
ranty.
IMPORTANT:
Do not connect Dispenser to
electrical power until you have
filled the tank. See instructions
on page 7.
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.

OPERATION
A. START-UP
For initial start-up, or if the dispenser has not been used for an
extended period of time:
♦ 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 dispenser.
1. Verify the water supply is properly connected and the water supply
valve is turned ON.
2. Be sure the TANK HEATER SWITCH is OFF before connecting
the dispenser to electric power. Plug the power cord into an
appropriate electrical receptacle.
3. Allow the tank to fill for several minutes. Place an empty container
under the dispense nozzle.
Press and hold the SAFETY switch, then press the DISPENSE
push-button. When water flows from the nozzle in a steady stream,
tank is full.
4. Press the TANK HEATER SWITCH ON. When READY light glows,
unit is ready for use.
5. Be sure the DRIP TRAY is empty and the CUP GRID is properly
installed. Locate the cup grid and drip tray in place under the
dispense nozzle.
B. USING THE DISPENSER
Place a cup on the cup grid. DO NOT hold cup while filling.
Press and hold SAFETY switch.
Press DISPENSE push-button. Release when water in cup reaches
desired level. Release SAFETY switch. Remove cup from cup grid.
Be careful not to spill or splash water from cup

IMPORTANT:
TANK MUST BE FULL
OF WATER BEFORE
CONNECTING BREWER
TO ELECTRIC 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.
CAUTION:
BURN HAZARD
This appliance dispenses
very hot liquid. Serious
burns can occur from
contact with dispensed
liquids.
DO NOT hold cup while
filling.
DO NOT spill or splash
water from cup.

OPERATION
8
Fig. 4 Dispenser Operation Diagram
WATER HEATER
Water temperature is sensed by thermobulb inserted into the water tank. Temperature is controlled
by a mechanical thermostat.
The setpoint temperature is adjustable by turning the thermostat shaft.
Excessive temperature will trip the hi-limit safety switch, disabling the heating element. The hi-limit
will automatically reset when the dispenser cools.
WATER LEVEL
Water level is controlled by an electronic controller. The water level probe senses chassis ground
through the water. When the water level is below the probe no ground is sensed. The controller
opens the fill solenoid until the water level makes contact with the probe.
DISPENSING
Heated water flows from the tank to the dispense nozzle through an electrically controlled solenoid.
Both the safety switch and the dispense push-button must be pressed at the same time in order to
activate the dispense solenoid.
