data label of the Brewer.

UNPACKING AND INSPECTION

Carefully unpack the Brewer by cutting the straps and lifting the carton off the Brewer.

ASSEMBLY AND SET-UP

The Brewer is shipped complete with:

DESCRIPTION

BC1, 301, 120, 240

BC2, 302

Adjustable legs

Carriers complete with Faucets and Covers

Funnels with sample Filter pack

Remove carriers from Brewer, one has the four (4) legs packed inside. Install legs by tilting Brewer on its

back and screwing the legs into the threaded leg supports on bottom.

WATER HOOK UP

The National Sanitation Foundation (NSF) requires the following for NSF approved installation:

1. A quick disconnect water connection or enough extra coiled tubing (at least 2x the depth of the unit) so

that the Brewer can be moved for cleaning underneath.

2. An approved flow-back prevention device such as a double check valve to be installed between Brewer

and water supply.

WATER CONNECTION

The Brewer comes equipped with a ¼ inch compression water inlet fitting located in the back. Use a ¼ inch

copper tubing to connect the Brewer to a cold water supply. Water pressure should be: 20 PSI min. to 90

PSI max. An external shut-off valve and a water filtering system with a charcoal filter are highly

recommended.

Turn water supply on and check for leaks at the water inlet connections, tighten compression fitting if

necessary.

ELECTRICAL CONNECTIONS

A terminal block inside the base compartment is provided for electrical connections. Opening for field

conduit connections are provided in the bottom and the back of the base.

To access the Terminal Block, loosen the 2 screws on the side of the base cover. Disengage base cover

from rear panel by lifting base cover up and lifting back towards rear panel.

Note:

1. Neutral (N) and Ground Wires to be 14 AWG Minimum.

2. Field wiring must be suitable for 75º C.

3. Use Copper wire only for all power supply connections.

INITIAL PRIMING – Filling of Tank

The BC Brewers are shipped with the Thermostat in the OFF position. Do not turn Thermostat to the ON

position until the Brewer has been fully primed.

a. Turn water supply on and check for leaks at the water inlet connections. Tighten compression fitting if

necessary.

b. Turn on power to the Brewer. The Brewer will automatically start filling. After 6 minutes the filling cycle will

stop and the thermostat should be turned clockwise to the full ON position. Allow approximately 20 minutes for

the brewer to reach full brewing temperature (197'-203').

When the GREEN READY LIGHT comes ON the brewer is ready to brew the next batch of coffee.

NOTE: Before proceeding further, make sure the sample Filter pack has been removed from the

funnel.

CHECKING BREW CYCLE OUTPUTS.

The BC-Series brewers are factory preset to deliver the proper amount of brewing water for the 12 cup,

24 cup and 36 cup brew cycles. Nevertheless, it is a good practice to check the output levels prior to

brewing the first batch of coffee.

BC1 and BC2: Full 36 cups (3 decanters) per brew cycle with a 20% by-pass.

BC120 and BC240: Selectively 12 cups (1 decanter) or 24 cups (2 decanters) per brew cycle.

No by-Pass.

BC301 and BC302: Selectively 12, 24 and 36 cups per brew cycle with a 20% by-pass for the 36 cup

cycle only.

TO START A BREW CYCLE:

Turn Warmer Switch to the ON position. The Warmer Switches also double as CYCLE STOP switches.

With Funnel and Carrier in place activate GREEN BREW switch.

On BC120, BC240, BC301 and BC302 brewers first activate brew switches marked 12 cups and then

check output. Do the same with the 24 cup brew switch and the 36 cup brew switch for the BC301 and

BC302 units.

NOTE: 12 cups equal 1 full decanter.

If necessary adjust the timer(s) to increase or decrease output levels. See Timer adjustments.

Switches on (lit), depress Green Brew Switches. Total brew time will vary according to cups selected.

After funnel stops dripping, remove and empty funnels.

Warning: Remove Brew funnel ONLY after it has stopped dripping.

ADJUSTMENTS

1. BY-PASS FLOW VALVE ADJUSTMENTS

Depending on the model number, the BC Brewers have been factory set to brew 12, 24 and/or 36 cups of

coffee, with the BY-PASS adjusted for a 20% BY-PASS flow of brewing water for the 36 cup, brew output

only. Since water hardness, the brand of coffee, and the length of brew time are important factors in final

drink taste, it may be necessary to adjust the percentage of BY-PASS. In general, the more ground

coffee used for each brew, the higher the percentage of BY-PASS. Proceed as follows to adjust BY-

PASS:

Place empty carrier without cover under brew funnel.

a. Pull brew funnel out 3 inches, exposing BY-PASS outlet behind funnel.

b. Activate warmer/cycle stop switch. Switch will be lit.

c. Hold measuring cup under BY-PASS outlet and activate Green Brew Switch.

After 15 seconds, push warmer/cycle stop switch to stop cycle.

d. Measure ounces of water in cup and ounces of water in carrier. Divide ounces in cup by total volume

dispensed (add ounces in cup and carrier) to get the BY-PASS ratio.

e. To get more BY-PASS, turn slotted adjustment screw in spray-head adjuster Counter-ClockWise.

Turning adjuster screw clockwise will decrease the BY-PASS flow. See figure below.

NOTE: The BY-PASS valve is activated only when the 36 cup cycle is selected.

The BC301 and BC302 units do not use the BY-PASS when brewing for 12 and 24 cups.

The BC120 and BC240 models only brew for 12 or 24 cups and therefore do not have the BY-PASS.

3. THERMOSTAT ADJUSTMENT

The BC Brewers are factory set to deliver hot brewing water at 200' F. The water temperature, at the

spray head, should be between 195' F-203' F with the thermostat knob at its maximum clockwise position.

If adjustment is necessary, proceed as follows:

a. To RAISE water temperature, turn temperature control knob to

its maximum clockwise position. Remove the knob and locate

slotted adjustment screw inside hollow thermostat shaft. Using a

narrow-bladed screwdriver, engage slotted adjustment screw

and turn it 1/4 turn counter-clockwise. The thermostat will cut in

and the Green ready light will go off. When Green ready light

comes on after a few minutes, measure temperature and repeat

if necessary.

b. To LOWER water temperature, simply turn knob one notch counter-

clockwise to next lower number on dial.

HINT: To measure water temperature accurately, remove the spray-head for a solid water stream.

4. WATER FLOW RATE ADJUSTMENT

Locate adjustment screw on valve (as show here).

Using an Allen Key or a flat screwdriver, rotate ¼ turn at a time,

Clockwise (CW) to decrease water flow rate or

Counter-Clockwise (CCW) to increase water flow rate.

Check water flow output after each ¼ turn.

The SINGLE DISPENSE VALVE is factory adjusted to dispense

0.6 oz./sec. of water during the brew cycle (spray duration).

The DOUBLE/ DILUTION DISPENSE VALVE is factory adjusted,

on both sides, to dispense 0.22 oz./sec of water

during dilution cycle.

SPECIAL COMPONENTS TEST

1) CHECK DISPENSE VALVES FOR LIME BUILD-UP (Located inside top cabin)

Drain the water tank to just below the level of the Dispense Valves.

Remove the Valves and clean. You can take these valves apart by

hand as shown.

Replace the assembly as needed.

Replace the valve into the tank and refill tank.

2) WATER INLET VALVE (SOLENOID) TEST (Located inside bottom cabin)

Turn power off. If the water level rises inside the tank, and shoots out of

the overflow, the Water Inlet Valve is leaking. Disconnect wires from the

Water Inlet Valve coil and connect a 2 wire line cord to the terminals. Plug

it into a 115V outlet. If water flows in and stops when you pull it out, the

Valve is working fine. Repeat this test a few times. The problem may be

in the Probe. If the water does not flow in when the cord is plugged into

an electrical outlet, the Solenoid coil may be damaged, opened or the

valve may have an obstruction preventing the water from flowing in.

Clean or replace it.

A Check Valve is installed to prevent backflow.

To check proper function of Check Valve, disconnect water line from

the Check Valve, check for dripping from the disconnected end of the

Check Valve. If it leaks, replace it.

Water inlet Valve max. flow rate is 1.3 gal/min.

3) WATER LEVEL PROBE TEST (Located on tank top, inside top cabin)

If there is a lack of water, you will get an uneven flow.

Check the probe as follows:

Turn on the power and water supply. Check inside the tank to make

sure the water is not touching the Probe. Pull the wire and terminal out

of the Probe rod. If water starts flowing into the tank, the Probe may

be grounded, due to excessive liming. Check with Ohm meter. Clean

or replace.

TO SOLENOID

4) SOLID STATE WATER LEVEL CONTROL BOARD

TO PROBE

a) Make sure there is power input to the board at the terminals 2 & 3. Your

voltmeter should read 115 volts. It should read the same at terminals 1

& 3. This is the output power to electrify the coil of the solenoid valve to

open it. The lack of voltage at terminals 2 & 4 will indicate that the

water level board is not working properly.

GROUNDING PLATE IN

BACK OF THE BOARD

b) Make sure all wire connections to the board are tight.

c) The grounding plate at the top, in the back of the board, should be

securely grounded. The board will not work, or will work erratically, if it

is not grounded properly. If after this, the board is still failing to open

the water inlet valve, then replace it.

CLEANING AND SANITIZING

SANITIZING:

All food dispensing units should be sanitized periodically. All parts to be sanitized must be cleaned first.

To prepare a sanitizing solution:

ADD 2 TSP. OF LIQUID CLOROX BLEACH (5.25% CONCENTRATION) TO 1 GALLON OF WATER AT

ROOM TEMPERATURE (70°- 90°F).

Note: Always start with a unopened bottle of Clorox Bleach since the solution from an opened bottle has a

short life span.

• Soak all parts for a minimum of 3 min. in the sanitizing solution.

• Let all sanitized parts drain and dry naturally. DO NOT WIPE THEM DRY.

• Before using the sanitized unit (or parts) with food stuffs, rinse all parts thoroughly with water.

Water pipe connecting and fixtures directly connected to a potable water supply shall be sized, installed, and

maintained in accordance with Federal, Sate, and Local codes (section 7).

TO PREVENT CORROSION DAMAGE:

1. Carrier liners should be cleaned daily.

2. Use only neutral pH cleansers such as dish washing detergents to clean the unit. Do not use cleansers

containing alkalies, acids or harsh abrasives.

3. Use mild abrasive nylon or brass brushes for removing coffee deposits. Do not use steel wool, wire

brushes or other abrasive tools that will scratch the stainless steel surface.

4. Use recommended sanitizing solutions.

5. Let the unit dry naturally after sanitizing. Do not wipe them. Do not use the unit until completely dry.

DRAINING OF WATER TANK:

Fast draining of tank is possible by Drain Hose which is located behind the front panel and held in place by a

clamp to the side wall.

When draining of tank is required, always disconnect power supply and turn thermostat counterclockwise to the

OFF position.

CLEANING:

1. Wipe all exterior surfaces of the unit with a soft, damp cloth using warm water and mild detergent.

WARNING: Before attempting to clean the Warmer Deck, make sure the Warmer switches are "OFF"

and the Warmer Deck has cooled down to room temperature.

2. Clean all interior surfaces, in contact with the substance dispensed, thoroughly.

Caked-on residue may have to be soaked before removal. On metal or glass surfaces, stiff bristle brushes

may be used.

3. Rinse the cleaned unit thoroughly with warm water and let dry.

4. Empty contents from brew funnel, wash and let dry (use a mild dishwasher detergent).

CARE OF STAINLESS STEEL:

Stainless steel surfaces that come in contact with food substances must be cleaned every day. Many food

products contain acid, alkalies, salt and other substances that corrode the stainless steel. In order to prevent

the corrosion of the material, proper cleaning, and sanitizing must be performed.

When cleaning the stainless steel, only neutral pH cleansers are to be used. Highly acidic or alkaline cleansing

agents and chlorinating sanitizing solutions cause corrosion.

DELIMING OF TANK:

Minerals in water also cause corrosion if they are allowed to accumulate. Therefore, the interior walls should

be cleaned frequently in order to remove mineral deposits and prevent corrosion from occurring.

WARNING: Do not immerse Carrier into water or use in dishwasher.
