READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
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 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.
PLUMBER’S INSTALLATION INSTRUCTIONS (AUTOMATIC
BREWERS)
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 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 brewer be able to be moved for cleaning
underneath. Loops of copper tubing will satisfy this requirement.
See Figure 3 below.
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.
6
685 77110 Owners Manual Horizon™ Brewers
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.
INSTALLATION (continued)
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.
NOTE: Does not apply to 0443 and 0471 pour-over brewers.
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).
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:
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.
See Figure 4 at right.
IMPORTANT:
Do not connect brewer to
electrical power until you have
filled the tank. See instructions
on page 8.
685 77110 Owners Manual Horizon™ Brewers
