URN CHECK-OUT

Before you start brewing coffee in your Mini-Brew, be sure to check the operation of the urn using the following

procedure:

1. Turn thermostat knob to #10 position.

2. Place spray arm over one of the liners with the cover removed and push the "Brew" button (brew light will
come on). As soon as water starts to come out of spray arm, push the stop button (brew light will go out)
and drain any water in the liner.

3. Push the "Brew" button again (same as above) and let water spray into empty liner until it stops
automatically.

4. Using a gallon measure -- check the amount of water sprayed into liner. This will let you know how
much water is to be sprayed over and through the coffee grinds.

THIS URN HAS BEEN FACTORY SET TO SPRAY 2 3/4 GALLONS OF WATER DURING THE BREW CYCLE.

NOTE -- If you want to decrease the amount of water -- you should decrease the amount of time on the timer. If you want to

increase the amount of water -- you should increase the amount of time on the time r. (See instructions on page 7 for
adjusting the timer.)

5. When temperature on thermometer reaches approximately 205 degrees to 210 degrees, the urn should shut off.

6. You are now ready to brew coffee.

NOTE -- Model MB-2 coffee urns are factory set to sp ray 5 3/4 gallons of water during brew cycle.

FLAVORING IN - When putting a new urn into operation, the breaking-in process (generally known as "seasoning" or "burning-in") is
accomplished by making the first batch of coffee very strong and allowing it to remain in the urn at least three to four hours. If
possible, keep this first batch of coffee in overnight -- under low heat. Dispose of this first batch. Then clean out urn before making
coffee for serving.

CLEANING

BETWEEN BREWS --A quick rinse between brews is desirable.

1. Rinse liner by spraying water over empty liner for about 30 seconds.

2. Drain the water off. The urn is ready for the next brew.

DAILY -- Daily cleaning after the last batch of coffee is used should be a regular routine.

1. After all brewed coffee has been drawn from the urn, spray over two gallons of fresh hot water and
thoroughly brush it out with long handled brush.

2. Drain the water off, again spray over two gallons of fresh hot water, brush it out, and drain
again. Wipe down liner with clean towel.

3. If urn is not going to be used again immediately, put a gallon or so of fresh water in the liner.
Do not drain this water off until just before making next coffee brew.

TWICE A WEEK -- Coffee urns must have a special scouring twice a week. To scour the urn thoroughly:

1. Fill liner with water and add at least 1-1/2 ounces of coffee urn cleaning compound. Allow this

solution to remain in the liner approximately 30 minutes, during which time heat should be on
full.

2. Scrub inside of liner and inside of cover with long handled brush.

3. Use long, thin brush to clean coffee gauge glass. Use same brush to clean fitting at bottom of
liner and pipe connecting to coffee faucet.

4. Drain urn cleaning solution off and rinse three or four times with fresh hot water, repeating steps
3 and 4 again. Drain rinse water.

5. Occasionally, take faucet valves apart and clean thoroughly.

6. Leave a gallon or so of fresh water in urn until just before brewing next batch of coffee.
