Your Curtis ADS System is Factory Pre-Set and Ready to Go… Right from the Carton.

Following are the Factory Settings for your ALPHA™ DS Coffee Brewing Systems:

• Tank Temperature = 190°F

• Flavor Controls= Set at 100%

• Dispensing Mode Set for Manual Dispensing Generally there will never be a reason to change your ADS programming. However, should you need to make slight adjustments to meet your brewing needs, programming instructions are provided later in this manual.

System Requirements:

• Water Source 20 – 90 PSI (Minimum Flow Rate of 1 GPM)

• Electrical: See attached schematic for standard model or visit www.wilburcurtis.com for your model. Equipment to be installed to comply with applicable federal, state, or local plumbing/electrical codes having jurisdiction.

SETUP STEPS

The unit should be level (left to right and front to back), located on a solid counter top. Connect a water line from the water ﬁlter to the brewer. NOTE: Some type of water ﬁltration device must be used to maintain a trouble-free operation. (In areas with extremely hard water, we suggest that a sedimentary and taste & odor ﬁlter be installed.) This will prolong the life of your brewing system and enhance coffee quality.

The National Sanitation Foundation requires the following water connection:

1. A quick disconnect or additional coiled tubing (at least 2x the depth of the unit) so that the machine can be moved for cleaning underneath.

2. In some areas an approved backﬂow prevention device may be required between the brewer and the water supply.

1. Connect a water line from your facility to the 1/4” ﬂare water inlet ﬁtting of the valve, behind the machine. Water volume going to the machine should be stable. Use tubing sized sufﬁciently to provide a minimum ﬂow rate of one gallon per minute.

2. Plug the power cord into an electrical outlet rated at 20A.

3. Switch on the CONTROL switch that runs power to the components in the machine. The lights (display window & row of buttons) on the front door will activate and the heating tank will start to ﬁll.

4. Once the water level has risen and covered the heating element, turn on the power to the heating element at the HEATING ELEMENT switch behind the unit.

5. Water in the heating tank will require about 30 minutes to reach operating temperature (factory setting of 190°F). At this time the READY light will come on.

6. Remove and ﬁll the canisters with powdered cappuccino mixes.

OPERATION INSTRUCTIONS

1. Choose a ﬂavor. Place your cup under the spout beneath the desired ﬂavor.

2. Push the dispensing button for this ﬂavor.

3. Allow the Primo Cappuccino unit time to completely dispense the product.

Control Board and Membrane Control Panel

FUNCTIONS OF THE CONTROL BOARD

1. GEAR MOTOR SPEED is a powder dispensing adjustment and is accessed by mode level no. 1 when programmed.

2. PRESET DISPENSING Product is dispensed at a measured amount when the PUSH button is pressed.

3. MANUAL DISPENSING allows the user to dispense product for as long as the PUSH button is pressed.

4. STOP will cancel a preset dispense cycle.

5. WASH CYCLE is used in conjunction with a PUSH button, to ﬂush the whipper chambers.

PROGRAMMING

Programming Mode PC-2D, PC-3D, PC-4D To enter the programming mode, press and hold any two of the PUSH buttons on the membrane control panel simultaneously, until all lights start blinking. Then release the buttons and choose any mode of operations for any of the PUSH buttons. Press STOP button if both PUSH buttons were not pressed simultaneously. Programming Mode PC-1D To enter the programming mode, press and hold the PUSH button and the STOP/WASH button on the membrane panel simultaneously, until the indicator light starts blinking. Then release the buttons and choose any mode of operation. Press STOP/WASH button if both buttons were not pressed simultaneously. While in the programming mode you may perform the following three functions:

1. Powder Dispensing Mode. Controls dispensing powder anywhere from 10% to 100% by volume. Press and hold the selected PUSH button for approximately one second, then release. The number of ﬂashes represent the set volume for this button (see table). To change the volume, press and hold the button until its light starts quick ﬂashing. Each quick ﬂash increases the volume by 10%. Release the button when the desired volume is achieved. After releasing the button, the number of blinks represent the new setting. To exit the Powder Dispensing Mode, push one of the other PUSH buttons.

2. Preset Liquid Dispensing Mode. This mode allows you to set the time for automatic dispensing. To select or change the timing while in the programming mode, press and hold the selected PUSH button until the liquid begins to ﬂow, then release. The timing starts when liquid begins to ﬂow. When the desired volume is achieved, press once again to stop the dispensing. You have now set the timing for this button and have exited the programming mode. If you press the selected button, it will dispense the liquid per your setting. To reset the timing, you must start from the programming mode.

3. Manual Liquid Dispensing Mode. While you are in the programming mode, press and hold the PUSH button, until the liquid stops ﬂowing, then release the button. At this time, you have selected the Manual Liquid Dispensing Mode and have exited the programming mode.

HEATING ELEMENT TOGGLE SWITCH

The heating element in the heating tank may be turned off in the Primo Cappuccino to allow the operator to use the unit for cold drinks. Located behind the unit are two toggle switches. The one on the bottom is the power switch for shutting down the complete unit. The top switch powers the heating ele ment. Flip down to turn it OFF. Up turns ON the element.

ADJUSTING THE TEMPERATURE: Factory Setting 190º

The water level/temperature circuit board, WC-3777, serves two functions. As the name implies, it is both a thermostat and water level control. This electronic board maintains the water level using a probe in the tank. Water temperature in the tank is controlled by a sensor bolted on the outside of the tank, just under the heating element terminals.

1. Open the front door. Remove the hinged top cover.

2. Remove the left side panel.

3. Locate the water level/temperature board, on the left side of the frame.

4. Near the center of the board you will ﬁnd a pair of tiny ‘shorting plugs’ attached to two pairs of pins (see

illustration, right). Just above this is a chart that displays the various combinations you may choose that will give you temperatures between 170º F and 200º F. Pull out or insert the shorting plug in any conﬁguration that

will result in the desired temperature.

5. Return the side panel and cover to on the unit.

DAILY CLEANING

1. Wipe all exterior surfaces with a damp cloth; removing any spills, dust or debris from the unit.

2. Pull out the drip drawer and screen. Wash out its contents. For hard to clean deposits, use a mild, nonabrasive solution of dishwashing detergent and water.

3. Clean around the dispensing area, wiping with a nontoxic cleaner.
