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 nal 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. Bloomeld 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.

REFER TO EXPLODED VIEWS PAGES 18 thru 22 FOR

COMPONENT NAMES/NUMBERS

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.

PLUMBER’S INSTALLATION INSTRUCTIONS IMPORTANT: This equipment must be installed to comply

with all applicable federal, state and local plumbing codes and ordinances; specically: The Basic Plumbing Code of Building Ofcials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).

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 ush 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 ow thru the valve.

913 p/n 2M-75937 Owners Manual 8718, 8738 Coffee Brewer

INSTALLATION (continued)

The water line must terminate in a 3/8” MNTP quick-disconnect tting, which will connect to the provided ex line. See Figure 2 below.

Fig. 2 Water Supply Installation

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.

In some areas, local codes require a backow preventer (check valve) to be installed on the inlet water line. If a backow

preventer is used, you

incoming line, between the backow 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.

WaRRaNTY.

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 T

BEFORE energizing the tank heater ThE WaTER TaNk MuST BE FIllED. Place an empty decanter under the brew head. With

the TANK HEATER SWITCH OFF, press the START BREW

SWITCH. Run at least three full brew cycles, or until water ows from the brew head. When water stops dripping, empty the container.

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.

WATER FLOW

AUTOMATIC OPERATION

Pressing BREW button energizes the

solenoid valve, allowing water from

anexternal water supply to ow 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 ow control device so that ow is consistent between 20 p.s.i. and 90 p.s.i.

Length of time the solenoid is open is

controlled by the timer.

Fig. 5 heat Control Diagram

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.

The faucet is at supply water pressure any time the faucet shut-off valve is OPEN.

CAUTION:

BURN HAZARD

Exposed surfaces of the

brewer, brew chamber and decanter may be HOT to

the touch, and can cause

serious burns.

CAUTION:

BURN HAZARD

To avoid splashing or

overowing hot liquids,

ALWAYS place an empty

decanter under the brew chamber before starting the brew cycle. Failure to

comply can cause serious

burns.

CAUTION:

BURN HAZARD

After a brew cycle, brew chamber contents are HOT. Remove the brew chamber and dispose of used grounds with care.

Failure to comply can

cause serious burns.

NOTE: Water for the hot water faucet is heated in a coil inside of the water

tank. Use of the faucet will

not affect the volume of

water delivered for a brew.

However, overuse of the

faucet during a brew may

lower the temperature of

the brew water.

A. PREPARATION

Place one (1) genuine Bloomeld paper lter in the brew chamber.

Add a pre-measured amount of

fresh coffee grounds. Gently shake the brew chamber to level the bed of grounds. Slide the brew chamber into place under the brew head.

B. AUTOMATIC OPERATION

BE sure “HEAT” light is not lit.

Place the appropriate EMPTY decanter in place under the brew

chamber.

Press the “BREW” switch. The solenoid will open for an amount of

time determined by the timer setting, admitting a measured quantity of water into the tank.

Inlet water will displace a like amount of heated water from the tank.

The hot water will be forced into the brew head where it will spray over the bed of grounds. Freshly brewed coffee will begin to ll the decanter under the brew chamber.

At the end of the brew cycle, some time will be required for all water

drips out of the brew chamber as coffee. When the ow and all dripping stops, the coffee is ready to serve.

Discard the contents of the brew chamber and rinse it in a sink.

When the ”READY TO BREW” light comes on, the brewer is ready for another brew cycle.

C. WARMERS

Press either the MAIN warmer switch to energize the main warmer,

or the FRONT or REAR warmer switch to energize an auxiliary

warmer. Set the lled decanter on the selected warmer to keep it warm.

SERVICING INSTRUCTIONS (continued)

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 qualied and experienced service personnel.

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.

NOTE: Normally, silicone hoses

do not need to be delimed.

Should deliming hoses

become necessary, Bloomeld

recommends replacing the

hoses.

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

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.

8. Reinstall wiring to heating element and thermostat. Reinstall the hi-limit thermostat (if removed). For brewers with hot water faucet, reassemble faucet piping. 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.
