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 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.

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.

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.

Bloomfield 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.

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 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. A flex 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 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.

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 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.

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

IL1627

Fig. 3 Model 8773 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.

For automatic brewers, be sure the water supply is properly connected and the water supply valve is turned ON.

BEFORE

plugging the brewer into a receptacle, or otherwise connecting brewer to electrical power thE WAtER tANk MuSt

BE FIllED

. Place an empty container under the brew head. Lift the pour-over cover then pour three decanters of warm tap water into the pour-over opening. Water will begin to flow from the brew head. When all water flow stops, empty the container.

Once the tank is full of water, connect the brewer to electrical power. Press the tank heater switch to ON. The heating elements will begin heating the water in the tank. When the water has reached the proper temperature, the “READY TO BREW” light will glow.

IL1618

OPERATION (continued)

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-temperature by a hi-limit thermostat.

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

Fig. 5 heat Control Diagram

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.

AUTOMATIC OPERATION (8773 only)

Pressing BREW button energizes the solenoid valve, allowing water from an external water supply to flow 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 flow control device so that flow 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.

NOTE:

Any abrasion or roughness on the flat end of the seat cup will require replacing the seat cup:

Work the seat cup out of the bonnet and off of the end of the stem.

Install a new seat cup, making sure the knob on the stem is fully inserted into the pocket of the seat cup, and the skirt of the seat cup is fully inserted into the bonnet.

CAUTION:

ChEMICAL BURN hAzARD

Deliming chemicals may be caustic. Wear appropriate protective gloves and goggles during this procedure.

Never siphon deliming chemicals or solutions by mouth.

This operation should only be performed by qualified and experienced service personnel.

PROCEDURE: Delime the Water Tank

PRECAUTIONS: Disconnect brewer from electric power.

Allow brewer to cool.

FREQUENCY: As required (Brewer slow to heat)

TOOLS: Deliming Solution

Protective Gloves, Goggles & Apron

Mild Detergent, Clean Soft Cloth or Sponge

Bristle Brush, Bottle Brush

Large Sink (or other appropriate work area)

IMPORTANT:

DO NOT spill, splash or pour water or deliming solution into or over any internal component other than the inside of the water tank.

IMPORTANT:

DO NOT allow any internal components to come into contact with the deliming solution. Take care to keep all internal components dry.

NOTE:

Repeat steps 4 thru 5 as required to remove all scale and lime build-up.

1. Disconnect brewer from the electrical supply. For automatic brewers, turn off the water shut-off valve and disconnect the water supply line from the brewer inlet fitting.

2.. Remove the tank lid assembly as described on page 13.

3. Remove the water tank from the brewer body by lifting straight up. Empty all water from the tank. Set the tank back into the brewer.

4. Mix 2 quarts of deliming solution according to the manufacturer’s directions. Carefully pour the deliming solution into the water tank. Lower the lid assembly back onto the tank. Allow to sit for 30 minutes, or as directed by the manufacturer.

5. At end of soaking period, remove lid assembly from tank.

Thoroughly rinse internal components of lid assembly with clear water. Using a stiff bristle brush, scrub the heating element (and faucet water coil on automatic brewers) to remove lime and calcium build-up. Rinse with clean water.

Store lid assembly in a safe location .

6. Remove the tank from the brewer and empty. Using a stiff bristle brush, scrub the interior of the water tank to remove lime and calcium build-up. Rinse with clean water.

16


7. Set the tank back into the brewer. Reassemble the tank lid to the water tank. Make sure the gasket is properly in place, then reinstall the hold-down strap.

8. Reinstall wiring to heating element and thermostat. Reinstall the hi-limit thermostat (if removed). For automatic brewers, reassemble piping for the faucet. Verify that all internal components are dry, then reinstall the top panel.

9. Reconnect brewer to electrical supply and, for automatic brewers, reconnect water supply.

10. Install the brew chamber without filter paper or grounds.

Run at least three full brew cycles and discard all water generated.

11. Brewer is ready to use.

NOTE:

Normally, silicone hoses do not need to be delimed.

Should deliming hoses become necessary, Bloomfield recommends replacing the hoses.
