INSTALLATION (continued)

READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION

CAUTION:

ELECTRICAL

DAMAGE

PLUMBER’S INSTALLATION INSTRUCTIONS (AUTOMATIC

BREWERS)

Brewer should be connected to a POTABLE WATER, COLD

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.

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.

IMPORTANT:

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.

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.

See instructions for filling tank,

page 8.

Damage caused by operating

the brewer without water in the

tank is NOT COVERED BY

WARRANTY.

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. Loops of copper tubing will satisfy this requirement.

See Figure 3 below.

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.

Fig. 3 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.

INSTALLATION (continued)

ELECTRICIAN’S INSTALLATION INSTRUCTIONS

WARNING:

REFER TO ELECTRICAL SPECIFICATIONS - Page 1

Check the nameplate to determine correct electrical service

required for the Brewer to be installed.

SHOCK HAZARD

Brewer must be properly

grounded to prevent possible

shock hazard. DO NOT

assume a plumbing line will

provide such a ground.

IMPORTANT: Before connecting to electricity, make sure

automatic brewers are connected to the water supply.

NOTE: Does not apply to 0443 and 0471 pour-over brewers.

Electrical shock will cause death

or serious injury.

All models are equipped with a cord and plug. They require a

115 - 125 volt 20 amp circuit (50/60 Hz, 2 wire plus ground, with

NEMA 5-15R or 5-20R Receptacle).

IMPORTANT:

See Figure 4 at right.

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:

Do not connect brewer to

electrical power until you have

filled the tank. See instructions

on page 8.

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.
