INSTALLATION INSTRUCTIONS

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 final 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.

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.

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 (#33) and Spray Disk (#34) are properly installed.

LEVELING THE UNIT

Verify that an adjustable leg is installed at each corner of the brewer.

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

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.

The provided water line strainer must be installed in the supply line, between the shutoff valve and inlet fitting. Note FLOW arrow marking on strainer body.

4

INSTALLATION INSTRUCTIONS (continued)

NSF requires that the brewer be able to be moved for cleaning underneath. A flex line or loops of copper tubing will satisfy this requirement. See Figure 2 below.

Fig. 2 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.

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.

Models 1012, 1040 & 1072 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 or 5-20R Receptacle).

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.

NOTE: This equipment must be installed to comply with all applicable federal, state and local plumbing codes and ordinances.

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 filled with water.

Pour water into the pour-over opening until water flows 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 performance. Such damage is not covered by warranty.

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.

A. START-UP

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 TANK IS FILLED

BEFORE plugging the brewer into a receptacle, or otherwise connecting brewer to electrical power THE WATER TANK MUST the pour-over cover then pour warm tap water into the pour-over opening until water flows from the brew head. When water stops dripping from the brew head, empty the container.

Once the tank is full of water, connect the brewer to electrical power. For Models 1016 & 1074, press power switch to ON.

The heating elements will begin heating the water in the tank.

When the water has reached the proper temperature, the

“HEAT” LED will go out.

6

OPERATION (continued)

WATER HEATER

Water temperature is sensed by an electronic water temperature probe inserted into the water tank.

This temperature signal is fed to the controller.

The setpoint temperature is adjustable. The controller sends a command signal to the power board based upon a comparison between the setpoint temperature and actual temperature.

See page 17.

The power board energizes the heating elements based on the command signal from the controller.

Excessive temperature will trip the hi-limit safety switch. The hi-limit will automatically reset when the brewer cools.

WATER FLOW

POUR-OVER FEATURE

Pouring any amount of water into the pour-over opening and into the basin pan forces an identical amount of heated water out of the tank and through the spray head.

AUTOMATIC OPERATION

Pressing the BREW key energizes the solenoid valve, allowing water from an external water supply to flow into the water tank. The incoming water forces heated water out of the tank to perform the brew.

The solenoid uses a flow control device so that flow is consistent between 20 p.s.i. and 90 p.s.i.

The length of time the solenoid is open is controlled by the time setting of the controller. See page 18.

After the solenoid closes, water will continue to flow to the brew chamber until the water level in the tank falls below the brew pickup, breaking the siphon.

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.

Hot water is provided at the faucet, at supply water pressure, any time the faucet shut-off valve is

OPEN

.

.

Press the ON/OFF key. Four beeps will sound and all lights will flash once. The POWER indicator will remain

ON

. If the water temperature is more than 10ºF below the setpoint, the HEAT indicator will glow until water temperature reaches setpoint.

Press the ON/OFF key again to turn the brewer

OFF

. Three beeps will sound, the tank heater and all warmers will be switched off, and all indicator lights will go out.

Brew Settings

See pages 17 & 18 for setting Brew Time and Temperature.

ABS™ (Automatic Brew Start)

Start a brew by pressing BREW. A single beep will sound. The system will verify that the water in the tank is at the proper temperature. If it is, brew will start immediately. Otherwise, the BREW indicator will flash

(Brew Waiting Mode) until the water reaches setpoint temperature, then the indicator will glow and brew will commence. If the main warmer is off, it will be energized automatically.

At the conclusion of the brew cycle, three beeps will sound.

NOTE: To override Brew Waiting Mode, press and hold the BREW key for 3 seconds while the BREW indicator is flashing. Brew will begin regardless of water temperature. To avoid under-temperature brews, this feature should only be used when setting brew volumes.

NOTE: Brew Waiting Mode (BREW indicator flashing) prevents multiple, unattended brews. While the BREW indicator is on or flashing, any additional strokes of the BREW key will be ignored (there will be a beep each time the key is pressed, however). Another brew cannot be initiated until the previous brew is complete.

The Brew Waiting Time, also called Dripout Time, (interval between when the brew is initiated and the audible signal sounds at the end of the brew) may be adjusted between 2 and 8 minutes at the Brew

Signal Timer dial on the controller. See page 18.

Brew Cancel

To cancel a brew in progress or a brew in waiting, press the CANCEL key. Two beeps will sound and the BREW indicator will go out.

NOTE: If a brew in progress is cancelled, coffee will continue to flow until all water delivered has dripped through the brew chamber.

Quality Timer

Coffee looses its freshness as it sits on a warmer. The Quality Timer flashes the warmer lights 30 minutes after the last brew to remind you that the coffee is nearing the end of its useful life.

After Hours™ Operation

During normal operation, the controller will maintain the precise brewing temperature. If, however, if the BREW key in not pressed for

3 hours, the brewer goes into After Hours™ mode; any warmer left on will be turned off; and, the temperature will only be maintained to within

20ºF. This feature prolongs component life and saves energy.

As soon as the BREW key is pressed, the brewer returns to normal operation, heating the water to the precise temperature before beginning the brew. The brewer will return to After Hours™ mode only if three hours pass without a brew being initiated.

Disable/Enable After Hours™ Feature

To disable After Hours™, press the ON/OFF key to turn the brewer

OFF

.

Press and hold the CANCEL key until two beeps sound, and the HEAT indicator flashes twice. This feature is now disabled.

To re-enable After Hours™, press the ON/OFF key to turn the brewer

OFF

. Press and hold the CANCEL key until three beeps sound, and the

POWER indicator flashes twice. This feature is now enabled, however, it will not be activated unless no brew is initiated for three hours.

Over-Temperature and Temperature Fault Protection

Should the water temperature exceed 214ºF (101ºC), or if the controller does not detect a 2ºF (1ºC) rise in temperature within four minutes of calling for heat, the brewer will go into Over Temperature Mode; the heating element is turned off, all warmers are disabled and all lights will flash.

Possible causes of Over Temperature condition:

• Setpoint is in the boiling range.

• Heating element or temperature probe has malfunctioned.

• Excessive scale buildup is preventing the element from heating the water.

• Heating element relay fails in the “on” state.

• No water in the tank.

• Hi-limit safety tripped (must be manually reset)

To reset the brewer:

• Determine the cause of the failure and take appropriate remedial action to rectify the problem.

• Press and hold the CANCEL key for three seconds. Four beeps will sound and the brewer will resume normal operation.

Quality Timer is normally set for 30 minutes. It can be set for 20 minutes by moving a jumper on the controller. See page 17.

After Hours™ is an energy saving feature. The brewer will enter After

Hours™ mode if it is not used for three hours.

Press the BREW key to immediately return the brewer to normal operation.

IMPORTANT:

If the original cause of the problem has not been addressed, the brewer will once again go into Over

Temperature mode four minutes after being reset.

ERROR DETECTION

This brewer is designed to perform a continuous internal diagnosis, and to signal faults by flashing all the lights. In fault mode, warmers, heating element and water fill solenoid are turned

“off”, and most keypad functions are disabled.

Error detection (all lights flashing) will occur under two conditions:

• Anytime a temperature in excess of 214ºF is detected.

• Temperature does not change by at least 2ºF within 4 minutes of tank heater being energized (HEAT light on).

To reset the brewer after the fault has been corrected, press and hold the CANCEL key for 3 seconds, or disconnect the brewer from electrical power for three seconds.

CAUTION:

SHOCK HAZARD

Live electrical circuits may be exposed while performing these procedures.

These procedures are to be performed by qualified technical personnel only.

WHAT TO CHECK DESCRIPTION

Has the water tank been properly filled?

On initial startup, an attempt to heat a dry tank will be detected as too high a temperature or insufficient temp rise, or will trip the high limit.

CORRECTIVE ACTION

Tank must be properly filled as detailed on page 6.

Check hi-limit (see below)

Has hi-limit safety thermostat tripped off?

Check control board and temp probe.

Brewer may have been started without water in the tank, or the temp control thermostat may require adjustment.

Brewer will go into error mode immediately if either the control board or temp probe is defective.

Temp probe electrical resistance is approximately 30K

Ω at room temp, and

2K

Ω at boiling. Replace temp probe if less than 1K

Ω.

Access hi-limit by removing front panel. Hi-limit is on the left side of the tank. Use an insulated tool to push the red button in until it “clicks” and stays. Reset per above.

Reset by holding the CANCEL key for

3 seconds. If lights continue to flash:

Disconnect temp probe from control board. a. If lights continue to flash, unplug

brewer and replace control board. b. If lights stop flashing, unplug

brewer and replace temp probe.

Check power board and heating element..

Brewer will go into error mode 4 minutes after energizing the heating element if insufficient heat rise is detected. The heating element is energized by an electronic power board, and protected by the hi-limit safety.

Heating element should receive full line voltage (i.e. 120V, 208V or 240V).

Be sure the hi-limit safety is reset.

Reset by holding the CANCEL key for 3 seconds. If lights resume flashing after 4 minutes:

Check the voltage across the heating element terminals: a. If no voltage is present, unplug

brewer and replace power board. b. If proper voltage is present,

unplug brewer and replace tank

heating element.

Is the brew temperature properly adjusted?

The brewer may occasionally go into error mode if the brew temperature is set too high.

See page 17 for temperature adjustment procedure.

Table 1 Boiling Temperature by Altitude

Upon completion, remove thermometer and reinstall vent tube.

CAUTION:

SHOCK HAZARD

These procedures involve exposed electrical circuits.

These procedures are to be performed by qualified technical personnel only.

NOTE: Optimum brewing temperature is 195ºF to 205ºF

(90ºC to 96ºC).

Maximum temperature setting should be no more than 205ºF

(96ºC).

IMPORTANT:

An electronic temperature controller will maintain temperature within ±2ºF.

To prevent boiling water in the brewer, controller should be adjusted to a maximum temperature equal to the local boiling temperature minus 2ºF, or 205ºF, whichever is less.

15


IMPORTANT: Water pressure must be between 20 p.s.i and

90 p.s.i. flowing pressure.

If water pressure exceeds this value, or if water pressure varies greatly, a pressure regulator must be installed in the water supply line.

Fig. 15 Adjust BrewTime

and Dripout Time

IMPORTANT: Before setting assembly into tank, make sure tank lid gasket is properly seated on flange of lid.

DO NOT OVER-TIGHTEN.

IMPORTANT: When replacing temperature probe, be sure a new seal washer is in place around the probe. Tighten jamb lock nut only enough to ensure no water leakage. Excessive tightening is not necessary.

IMPORTANT: When replacing heating element, also replace seal gaskets.

BREW TIME ADJUSTMENT

The amount of water dispensed automatically during a brew cycle is controlled by the SOLENOID TIME dial of the controller.

Place empty decanter under brew chamber. Press BREW button. Brewer should dispense one full decanter of water. To adjust amount:

Remove brew chamber and button plug. On the controller, adjust

SOLENOID TIME dial (BREW TIME); clockwise increases time.

Run several cycles to check amount of water delivered.

DRIPOUT TIME ADJUSTMENT

Water delivered to the brew chamber will take a while to drip through as coffee. The time between the end of a brew and when a new brew can be initiated is controlled by the BREW

SIGNAL TIMER. Adjust the BREW SIGNAL TIMER dial on the controller to account for the dripout time. Replace button plug.
