To ensure food safety and proper operation, clean machine regularly following the daily and weekly cleaning instructions. Cleaning and water evacuation instructions are found in the Cleaning and Maintenance Section of this manual.

When turning off the machine for an extended period, be sure to evacuate the water inside the piping completely. Otherwise, the water inside the machine could freeze and lead to damage or cause mold to appear.

heat to brewing temperature. (Hot water may drip from brew basket on initial thermal expansion of water in the tank). This will not occur thereafter.

8.After water has reached brewing temperature (thermostat will click off, heating noise will stop), pour 1 decanter (60 oz.) of water through pour-in opening. More than 1 decanter of water will flow into decanter below brew basket due to water expansion in tank. Machine is now ready to use.

9.Pour 1 decanter of water through pour-in opening to check for proper temperature setting with an accurate thermometer. Take the temperature of this water at a point below the brew basket opening at the start of the brew cycle and when the decanter is half full. Recommended temperature of the water is approximately 195°F.

10.In higher altitude locations (5,000 feet above sea level) the thermostat may have to be adjusted lower to prevent boiling.

Installation

WARNING Read and follow installation instructions before plugging machine into an electrical circuit. Warranty will be void if unit is connected to any voltage other than that listed on the name plate.

NOTICE: Fill brewer tank with water before connecting to power supply.

Please read this manual before operating the brewer.

1.Carefully remove brewer from carton.

2.Place brewer in position on shelf, counter or other flat surface.

3.FILL BREWER TANK WITH WATER BEFORE CONNECTING TO POWER SUPPLY

4.Place the decanter under brew basket, raise pour-in opening cover and pour three decanters of water through the top pourin opening. Water should come through the brew basket as the third decanter of water drains out of the pour-in basin.

5.Brewer is shipped with thermostat turned on (full clockwise position). Plug brewer into a dedicated, grounded 120V/15A or 120V/20A (240V for export models) circuit depending on model (refer to serial tag on machine).

Cleaning & Maintenance

WARNING Burn Hazard. Hot liquids and surfaces are present in this equipment. To avoid burns, use caution when cleaning. Rinse hot parts with cold water before cleaning. Use gloves or a heavy cloth when removing hot parts from brewer.

Cleaning Instructions

After Each Brew:

1.Dispose of grounds and rinse brew basket.

2.Rinse decanter or airpot containers before reuse.

Every Day:

1.Wash brew basket with warm soapy water, thoroughly rinse and dry using a clean absorbent towel.

2.Remove spray head, located above brew basket, using gloves or a heavy towel. Wash off coffee oils and clean any plugged holes.

3.Wash Brew Funnel and Decanters or Airpot by hand as needed with warm soapy water, thoroughly rinse, and dry using a clean absorbent towel. Do not use dishwasher, which may cause airpot breakage.

4.To avoid scratches, use a soft cloth and warm soapy water or stainless steel polish on the outside.

5.Wipe exterior of brewer with a damp cloth. Do not use abrasives which will scratch surface.

6.If decanters are to be left on warmer all night, fill with water to avoid coffee oil burn-in.

Sanitizing:
