SETUP

Starting the Automatic Machine

Check and confirm that water source is in normal working order.
Turn the power switch to ON to initiate automatic system check. If boiler water level is not in the green zone, wait until the automatic water replenishment process is complete before proceeding to the next step.

Heating will stop when boiler pressure reaches approximately 1.2 bars (factory default setting). Do not operate the machine until steam pressure gauge reading is in the green zone.

Output Volume and Frequency Setup

No default coffee output setting is provided. Settings \must be made manually during setup.

Ensure that both the water level and steam pressure are in the green zone before proceeding.
There are two identical button suites on 2 group models \and three identical button suites on 3 group models.
For two and three-group machines, start by programming the buttons on the furthest group to the right and then move left. The programmed outputs will serve as default for the left group(s) until programmed differently.

To program your machine, turn the output volume setup switch ON (Fig. 1).
The output LEDs (Fig. 2) should be lit with the 5th button flashing, indicating the machine is in setup mode.
To configure output button 1, starting on the furthest right button suite, press and hold output button 1 until the desired output is reached. While the button is being held in, that LED will be lit and all other buttons will be shut off. Users can measure fluid ounces or time dispensed for their settings.

Once the desired output has been reached, release output button 1. At this point, LED 1 will be off and all other buttons will be lit.
Repeat steps to set up output buttons 2, 3, and 4, respectively.
The left set(s) of output buttons will mirror the value settings in the set of output buttons to its immediate right. Repeat steps 2 through 5 if different output volumes are desired for different groups.

The fifth button of each group head will remain a continuous flow. This means once you press this button, it will not turn off until pressed again.
- a. This button does not need to be programmed.
- b. Good for brewing larger amounts of espresso.

After completing setup, turn the output volume setup switch OFF to save all data and return the machine to normal operational mode.

OPERATION

The steam wand, hot water wand, and brewing group can reach very hot temperatures. Use caution while operating.

Brewing

Grind coffee beans to a fine consistency.
Fill the portafilter with coffee grounds. Make sure not to overfill the portafilter, or it will not reattach
onto the machine properly.
Tamp the coffee grounds into the portafilter using a tamper (Recommended: 236TAMPSS).

Secure the portafilter to the espresso machine with a quarter turn.
Use any of the presets to brew or use the continuous flow button.
Frothing Milk (Steam Wand Operation)

If using continuous flow, the brewing will continue until it is pressed again, stopping the brewing process.

Stopping the Machine

After cleaning the machine, remove all liquids and solid matter from the water tray.

Turn off the power.
Open the steam knob to release the steam flow. Do not place any liquid under the steam tube during this process to avoid system contamination.

CLEANING & MAINTENANCE

Machine Body

Wipe the machine exterior with a soft, slightly dampened cloth daily before starting operations.
If necessary, a mild, non-corrosive cleaning agent may be applied to the cloth. DO NOT spray cleaning agents directly on the machine body to avoid corrosion and possible damage to circuits.

Brewing System

WARNING: The brewing group is hot, allow to cool before cleaning or servicing.

After each brewing cycle, remove the portafilter and press the manual water output button to remove all residual coffee grounds from the filter element.
Knock any remaining grounds out of the portafilter.

Hold the portafilter underneath the brewing group and press the manual output button to rinse \out the rest of the grounds from the portafilter.
Place a reverse flushing silica plate in the portafilter, and apply about 2-3 grams of detergent. Attach the portafilter onto the machine and check for tightness.
Next, start the auto-reverse flushing process.

Press the first and fifth buttons simultaneously to start automatic reverse flushing. Output buttons \2-4 in the control panel will light and start automatic reverse flushing from the right output system to the left.
The default is 10 cleaning cycles.
If you want to stop before the completion of all 10 cleaning cycles, press button 3.

Flush one group after the other. You can press the third output button to skip the next output system.\ The system will stop automatically after all reverse flushing is finished.
After the auto-reverse flushing is complete, remove the portafilter and silica plate. Press the manual water output button to allow the residual cleaning solution in the brewing system to flow out. Turn water off after flushing for about one minute or until the water is clear and clean.
- a. .During reverse flushing, remove and wash the copper plate and filter element with clean\ tap water. Wipe with soft cloth.
- b. .If the process is unable to sufficiently clean the plate and filter element, immerse the components overnight in a mild cleaning solution of 3 tsp. detergent in 1 pint hot water.
Rinse and reassemble components before restarting the espresso machine.

Portafilter and Filter Basket

Rinse the portafilter with hot water after each brewing cycle to dissolve residual oils in the filter basket and outlet nozzle and prevent oils from affecting the quality of coffee.
Disassemble the portafilter and place all parts in cleaning solution (3 tsp. of detergent in 1 pint hot water) for 24 hours to dissolve residual coffee oils. DO NOT immerse the plastic portion in a cleaning solution to avoid deterioration.
Rinse all components with clean water. Wipe with a soft, clean cloth only.

Steam Tube

After making steamed milk, use a slightly moistened soft cloth to wipe steam tube.
After wiping, release a steam burst through the tube to remove any residual milk remaining in the nozzle.

If hardened milk residuals remain in the steam tube, disassemble and immerse the tube in hot water for about 20 minutes to soften. Reassemble and repeat step (1).

SHUTTING DOWN THE MACHINE

Boiler

To extend the serviceable life of your unit’s boiler, or when you expect the machine to sit idle for a long period\ of time:

Turn power to the machine OFF.
Open the steam output to discharge pressure in the boiler. Continue until the pressure gauge reading falls to zero and steam discharge ends.
If water does not discharge properly, place a tsp. of detergent into the discharge trough and flush with hot water to dissolve residual oils in the tube.

Once complete, empty and clean the water tray and discharge trough, following the instructions below: Leave the steam output setting open following steam discharge. Steam output should remain open until after the machine is turned back on and hot water begins dripping from the steam tube. Contact a service professional to deliver the unit every 6 months.

Water Tray and Discharge Trough

Remove the water tray. Wash thoroughly with cleaning solution and rinse with water.

After removing the water tray, wipe and remove sediments in the discharge trough with a wet cloth or napkin and wash with hot water to clear the discharge tube.
After the discharge trough is cleaned and the tray is dry, reassemble the water tray.

Filter

The manufacturer recommends replacing the filter element on the resin exchange filter after processing 53 gallons of water (about 3,000–4,000 cups of coffee). This schedule can be expected to vary based on the quality of water used in your machine
