GROUNDING INSTRUCTIONS

For your protection, the Waring™ Commercial Coffee Brewer is equipped with a 3-conductor cord set that has a molded 3-prong grounding-type plug, and should be used in combination with a properly connected grounding-type outlet, as shown in Figure 1. If a grounding-type outlet is not available, an adapter, shown in Figure 2, may be obtained so that a 2-slot wall outlet can be used with a 3-prong plug. Referring to Figure 3, the adapter must be grounded by attaching its grounding lug under the screw of the outlet cover plate.

CAUTION: Before using an adapter, it must be determined that the outlet cover plate screw is properly grounded. If in doubt, consult a licensed electrician. Never use an adapter unless you are sure it is properly grounded.
NOTE: Use of an adapter is not permitted in Canada.

SHORT CORD INSTRUCTIONS

A short power-supply cord is provided to reduce the risk resulting from becoming entangled in or tripping over a longer cord.
If a longer detachable power-supply cord or extension cord is used, (1) the marked electrical rating of the extension cord should be at least as great as the electrical rating of the appliance, and (2) the longer cord should be arranged so that it will not drape over the countertop or tabletop where it can be pulled on by children or tripped over unintentionally.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT REMOVE (OR BACK) NO USER-SERVICEABLE PARTS INSIDE
REPAIR SHOULD BE DONE BY AUTHORIZED SERVICE PERSONNEL ONLY

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated, dangerous voltage within the product’s enclosure that may be of sufficient magnitude to constitute a risk of fire or electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

NOTE: The person installing the appliance is responsible for ensuring that electric and water connections meet the requirements of the national electric code, national plumbing code, and any local ordinances.

WATER HOOKUP
NOTE: The coffee brewer must be installed in compliance with applicable federal, state and/or local plumbing codes having jurisdiction. This product requires an approved backflow prevention water device, such as a double check valve, to be installed between the machine and the water supply. Incoming pressure should be greater than 30 psi and not more than 70 psi.

NOTE: Connecting the coffee brewer to a warm water supply will speed up heating and recovery times.

2. Provide shutoff valve and union in supply line near the coffee brewer.
3. Minimum inlet pressure at coffee brewer should be 30 psi and maximum inlet pressure recommended at 70 psi.
4. Turn on the water supply line and check for leaks.

NOTE: A filtering system is recommended to remove odors and inhibit lime and scale buildup in the unit.
NOTE: In areas with extremely hard water, a water softener must be installed in order to prevent mineral deposits that may cause malfunctioning of the equipment.

ELECTRICAL HOOKUP
NOTE: This equipment must be installed in compliance with applicable federal, state and/or local electrical codes having jurisdiction. Do not use extension cords. Make sure that the outlet is properly grounded.

1. Check rating marking on coffee brewer nameplate to be sure electric lines match voltage, phase, and amperage requirements of coffee brewer. Select the proper cord and cord grip for electrical rating of the coffee brewer.
2. For U.S., 120V coffee brewers are provided with a 120V/15A grounding plug.

8. Once the decanter is filled, simply discard the grounds and filter.
9. TURN OFF WARMERS WHEN NOT IN USE.

HOT WATER FAUCET ­ WCM50P/WCM60PT/WCM70PAP ONLY

   NOTE: Faucet will not work with the pour-in feature; brewer must be plumbed to a working water supply line.

INITIAL START-UP BEFORE BREWING COFFEE ­ MANUAL FILL (POUR OVER) ­ (OPTIONAL)
NOTE: WCM50P & WCM60PT are factory preset in Automatic mode. Never use manual pour-over mode if WCM50P & WCM60PT are in automatic mode. If manual operation is desired, brewer must be switched into manual mode through the rear access panel.

To adjust the volume output, locate the rear access panel on the rear of the unit. Find the dip switch section and identify the switch positions for desired volume.
NOTE: WCM70PAP is factory set to 85 oz.

FINE VOLUME ADJUSTMENT
When brewing, there may be a need to adjust the final brew volume based on the level of coffee in the carafe or airpot. The selector switch behind the rear access panel marked “OZ” can be adjusted to either increase or decrease the level in the carafe or airpot. The factory default setting is the zero position. To increase volume, turn switch clockwise; to decrease volume turn switch counterclockwise. In between brews, you can adjust the selector switch and run your next brew to confirm the new coffee level.

TEMPERATURE ADJUSTMENT

1. To access the temperature adjustment feature, unplug the power cord and see the back of the unit.

2. Open the rear access panel.

3. Locate temperature adjustment dial. Adjust thermostat by turning the dial: counterclockwise to decrease temperature, and clockwise to increase temperature.

CLEANING & MAINTENANCE

ALWAYS DISCONNECT OR UNPLUG THE COFFEE BREWER BEFORE CLEANING. Allow the brewer to cool completely before handling or before cleaning.

1. The use of a damp cloth rinsed in any mild, nonabrasive liquid detergent is recommended for cleaning all surfaces on Waring equipment. 14
   a. DO NOT use any cleaning fluids that can be harmful to you, others around you, or to the environment.
   b. DO NOT hose down, immerse or pressure wash any part of the coffee brewer.
   c. NEVER use steel wool or abrasive materials to clean the coffee brewer.
   NOTE: All sanitizing agents in the food zone must comply with U.S. Food & Drug Administration Code of Federal Regulations Title 21, Section 178.1010. Sanitize all food-dispensing units periodically. All parts to be sanitized must be cleaned first. Cleaning and sanitizing frequency must follow state and local health department regulations.
   NOTE: Do not use cleansers, bleach liquids, powders, or any other substance containing chlorine. These products promote corrosion and will pit the stainless steel. USE OF THESE PRODUCTS WILL VOID THE WARRANTY.

2. Check and clean the spray head underneath the front panel. The spray head holes must always remain open.

3. To remove the spray head from the brew head, follow the instructions below.

4. If brew basket is in place, remove in order to access the spray head.

5. Once brew basket has been removed, reach under the brew head and grab spray head with hand. NOTE: Make sure unit is completely cooled.

6. Gently but firmly pull down on the spray head to unlatch it.

7. Wipe inside of brew head and area around the brew head with a soft clean cloth or sponge moistened with clean water.

8. Wash the spray head in a sink using warm water and a mild detergent. A bristle brush may be used to clear clogged spray holes. Rinse the spray disk with clean water and allow to air-dry.

9. Once dry, reinstall the spray head under the brew head.

10. It’s recommended to clean the spray head at the end of every service week.

11. Wash the brew basket in a sink using warm water and a mild detergent. A bristle brush may be used to clean the inside. Rinse with clean water and allow to air-dry.

NOTE: In hard-water areas, this may need to be done more frequently. It will help prevent liming problems in the brewer and takes less than a minute to complete.
