Office Copy of Atomic Training Instructions

1. Season machine by filling it with water to capacity through the round opening at the rear of the neck. Screw on the safety valve knob, put a little DRIP GRIND espresso coffee in one of the filters, put the filter into the filter holder and then clamp it into the head of the machine. Check that the Cappuccino (knob) Valve on the side is closed and place the machine over a burner. Place the large coffee pitcher under the head of the machine and turn on the heat. After a short period when machine has rendered most of the water from the tank, it will labor and spurt. Turn off the heat, open the Cappuccino Valve first, in order to release any stored steam pressure, then unscrew the safety valve knob at the rear and pour out any residue water. Machine is now ready for use.

2. To save energy refill with hot water to capacity and replace safety valve knob. Never use brewed coffee instead of water.

3. Fill the larger of the two filters 3/4 full with DRIP GRIND espresso roast coffee ONLY (never with a very fine or fine grind - this will cause machine to malfunction, because it does not have hydromatic pressure). Have your coffee merchant give you DRIP grind only or use DRIP grind canned espresso.

4. Place filled filter into filter holder and lock it into the head. Check that Cappuccino valve is closed, replace the coffee pitcher and put the machine over moderate heat.

5. When machine has reached the boiling point, it will slowly start to render brewed coffee. The coffee will escape faster as machine gets hotter. When the coffee pitcher is quasi full and the speed of escaping coffee lesens to a slow spurt, then inject the brass pin with knob all the way into the horizontal opening at the bottom of the filter holder, give it a twist and wait a few minutes until the machine turns the residue water in the tank into steam. The brass pin is to be used only when the coffee spurts and labors. It won't shut off a full flow of coffee. It is normal for some coffee to spout out of the sides and bottom of the filter holder when closed off with the brass pin.

6. For best results- make coffee first- open Cappuccino valve to release steam pressure, replace coffee filter with Aluminum non perforated cup, lock it into head, refill half water and proceed to steam when ready. To frothe the milk, place about 2 oz. cold milk or a mixture of 2 oz. water and 1 Tb. powdered milk in an ordinary tea cup, place it under the steam stem with tip of stem slightly submerged under the surface of the milk. Blast the milk - and immediately close the valve - re-open and close slowly as needed while milk rises. Pour or spoon frothed milk over coffee or pour coffee down the side of the cup. Sprinkle with chocolate.

7. For smaller amounts of coffee use less water and the smaller coffee filter.

8. If knob of Cappuccino valve hard to turn, unloosen the stem ring.

9. ALWAYS UNLOOSEN the Safety Valve Knob when storing machine, in order to prevent corrosion of the knob.

For best results in frothing milk on a machine with a pressure gauge, follow instructions as given in par. 6 above and wait until gauge reaches 3 kg. Do not overheat machine or plastic dial cover will melt. The plastic piece is replaceable. If gauge indicator recedes to zero while machine is in operation, turn off the heat, this indicates that the water has been completely depleted.
