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 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.

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.

A waterline filter is recommended in areas where water quality may cause taste and/or odor problems.

642 75872 Owners Manual E.B.C. Airpot /Thermal

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 1080 and 1082 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: 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.

Models 1086 & 1088 must be wired by an electrician, and require a 115/230V 20A circuit (50/60 Hz, 2 hot legs / 1 neutral leg, plus ground). Remove front panel to gain access to terminal block. Green terminal must be connected to a suitable building ground. Circuit must be capable of 3500 Watts. See figure 3 at right.

642 75872 Owners Manual E.B.C. Airpot /Thermal

IMPORTANT: Wiring must be installed in approved solid or flexible conduit, and must be secured to the brewer with a strain relief (to be provided by the installer).

NOTE: This equipment must be installed to comply with 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 BE FILLED. Place an empty decanter under the brew head. Lift 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 1086 & 1088, 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.

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 15.

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
