INSTALLATION INSTRUCTIONS

READ ThIS CAREFULLY BEFORE STARTING ThE INSTALLATION

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.

IMPORTANT:

This equipment must be installed

to comply with all applicable

federal, state and local plumbing
codes and ordinances.

NOTE: Water supply inlet line
must meet certain minimum
criteria to insure successful

operation of the brewer.
Bloomeld 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.

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 (MODEL 8773
BREWERS ONLY)

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.

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 Fig. 2 at right.

INSTALLATION INSTRUCTIONS (continued)

IL1596

Fig. 2 Water Supply Installation - New-Style Brewers

In some areas, local codes require a backow preventer (check
valve) to be installed on the inlet water line. If a backow

preventer is used, you must install a water hammer arrester in
the incoming line, between the backow preventer and the brew-

er 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

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.

Domestic models 8773 & 8774 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).

Export models 8773 & 8774 are equipped with a cord and plug.

Refer to page 1 for circuit voltage requirements.

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:

Do not connect brewer to
electrical power until the tank

is lled with water. Pour water

into the pour-over opening until

water ows from the brew head.

IMPORTANT:

Supply power must match

nameplate for voltage and
phase. Connecting to the wrong
voltage will damage the brewer

or result in decreased perfor-

mance. 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 dam-

age. 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.

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-tempera-

ture by a hi-limit thermostat.

To save energy, press the TANK HEAT switch
to OFF if no brew is expected for an

extended period.

WATER FLOW

POUR-OVER FEATURE (8773 & 8774)

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.

Fig. 5 heat Control Diagram

AUTOMATIC OPERATION (8773 only)

Pressing BREW button energizes the

solenoid valve, allowing water from an
external 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.

hOT WATER FAUCET (8773 only)

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.

Hot water is provided at the faucet, at supply

water pressure, any time the faucet shut-off
valve is OPEN.
