The AC10-PC SureShot Dispensing Systems® Liquid Dispensers provide refrigerated liquids such as
cream, whole milk, skim milk, in automatically controlled portions. Product selections are made using touch
buttons on the front panel. Each button is pre-set independently at our factory to dispense a specified amount
of refrigerated product in accurate, portion-controlled quantities to your company’s specifications. The product
is stored in a sanitary, refrigerated compartment within the dispenser.

The AC10-PC model will dispense a dairy product in up to five different sizes from touch buttons on
the front of the dispenser.

1. Place cup under the product delivery tube.

2. Press button for the desired quantity of dairy product.

INSPECTION FOR DAMAGE

When you receive the dispenser, inspect the exterior of the shipping container for damage. Note any
damage in detail.
Uncrate the dispenser at once (see instructions below). Examine the dispenser for damage. Report any

ELECTRICAL REQUIREMENTS

Be sure the current at the power source receptacle is: 120 VAC, single phase, 3 Amp, 60 Hz.
The power cord is furnished with a UL-approved 3-prong attachment plug. This plug is designed to fit a
receptacle with provisions for a grounding stud. The dispenser includes a microcontroller and must be
operated on grounded electrical wiring at all times. Failure to do so will void the Warranty.

SERVICING - ELECTRICAL

Electrical servicing must be carried out by a qualified technician. The Warranty will be null and void if the
dispenser is serviced by unqualified personnel. If you need assistance, call the SureShot Dispensing
Systems® Technical Assistance Center at 1-888-777-9990 or 1-902-865-9602.

SERVICING - REFRIGERATION

Any servicing of the refrigeration system must be carried out by a qualified technician. The Warranty will be
null and void if the refrigeration system is serviced by unqualified personnel. If you need assistance, call the
SureShot Dispensing Systems® Technical Assistance Center at 1-888-777-9990 or 1-902-865-9602.

INSTALLATION AND LOCATION OF THE DISPENSER

1. Location of Dispenser:

• Place the dispenser where it will best serve your operation.

• Counters, platforms, or shelves should be strong enough to support the dispenser and full

containers of product. The empty AC10-PC dispenser weighs 60 pounds.

• Place the dispenser at the appropriate serving height so that people drawing product from the
dispenser can operate the buttons as well as easily place and remove cups.

• Leave clear space around the dispenser, approximately 1 inch (2.5 cm) on all sides.

• Do not place the dispenser too close to a source of heat or moisture. Allow a minimum 1 inch

(2.5 cm) airspace between machines at all times. The performance and efficiency of the
refrigeration system will be reduced if the dispenser is placed too close to a heat-generating
machine, such as a coffeemaker.

• Do not block the vents at the top rear of the dispenser. The vents must be free and open to
ensure proper operation of the ventilation system and to prevent over-heating and damage to the
system.

• The dispenser must be placed on a level surface or leveled by adjusting the legs. Not all
dispensers have adjustable legs. The dispenser must be level, left to right and front to back, to
dispense accurate quantities and to ensure proper functioning of the refrigeration system.

• Do not remove the legs or rubber feet from the dispenser or allow the dispenser to sit flat on the
counter. Airflow and circulation under the machine are essential for the proper operation of the
refrigeration system. Make sure the legs at the four corners of the bottom of the dispenser are in
place. If one has loosened during shipping, re-tighten it. Some dispenser models have
adjustable legs and these legs are secure even though they may appear to be loose. Removal of
the legs automatically voids the Warranty.

General Maintenance

• Gently remove ice build-up, if any ice forms. Ice build-up could indicate an improper temperature setting or an
improperly sealed door.

If the dispenser has accumulated ice or frost at the top of the refrigerated product compartment, it is best to
remove it by hand during a defrost cycle, which runs automatically and will be indicated on the LCD display panel
(DEF). Forming ice does not necessarily mean the temperature of the product is too cold.

Ice may be removed during a product change: unplug the dispenser. Leave the door open for about 15 minutes

to allow the ice to soften. Remove the ice by hand.
If a temperature adjustment is required, follow the instructions on page 15. If further assistance is required,
contact the SureShot Dispensing Systems® Technical Assistance Center at 1-888-777-9990 or 1-902-865-9602.

• If you have difficulty closing the door, check for ice buildup and remove to ensure proper operation.

• Check the door gaskets, to ensure there are no cuts or gaps. The door must close tightly to ensure proper

refrigeration.
Check the operation of the fan, being careful not to cut or injure fingers. The fan is located on the right side of the
dispenser, behind the front panel (See page 14). If the fan is not operating, call SureShot Dispensing Systems®
Technical Assistance Center at 1-888-777-9990 or 1-902-865-9602 for assistance.

Quantity/Volume Checks: To Adjust Dispense Amounts
To Verify Dispense Amounts

1. Before attempting adjustment of the volume amounts, perform the following:

- proximity switch continuity check

- valve removed and cleaned

- Insert a full bag of product, test and record all volumes

- Ensure the product tube is not pinched

- Ensure proper product temperature – do Product Temperature Check below

Product Temperature Check

1. It is imperative that your dispenser’s temperature is stabilized for at least 24 hours before attempting an adjustment.

2. Place product or water at 38 °F in a container. Place the container in the refrigerated compartment for 24 hours.

3. Check the temperature of the fluid. Do not rely on the LCD displayed temperature found on the front door.

4. If the fluid is not under 40 degrees, perform the Product Temperature Adjustment on the Circuit Board. See Page 15.

To Adjust Dispense Amounts – Circuit Board

1. Enter Program Mode by sliding the program mode switch (S3) on the Circuit Board to the “down” position. (Page 15)

2. Table selection can be accomplished for alternate products by pressing either the “UP” or “DOWN” buttons

6. Turn off the dispenser, wait 10 seconds, then turn the dispenser back on to reset
the microcontroller.

7. Check the temperature inside the refrigerated product compartment, to make
sure it is within the temperature range of 35 ºF to 40 ºF (1.6 ºC to 4.4 ºC). If the
dispenser is running cold, it could form ice which may interfere with the flow of
product.
If a temperature adjustment is required, see page 14, 15. If further assistance is
required, contact the A. C. Dispensing Equipment Inc. Technical Assistance
Center at 1-888-777-9990 or 1-902-865-9602.

The dispenser is not dispensing
the proper amount of product

1. Wrong dairy product is being dispensed – for example, skim istead of cream.

2. Check to ensure that the system is reset properly. See page 16.

3. Make sure that the product delivery tube is inserted in the valve correctly since
incorrect placement can affect product delivery. See page 7.

4. Check to ensure that valve and valve area are clean.

5. Make sure the valve door is not being opened before the product bag or tank is
empty.

6. Make sure product tanks are filled to the required level.

7. Check to see if the refrigeration unit is too cold or too warm. Ice may interfere
with product flow.
Check the product temperature to ensure it is approximately 38 ºF or 3.3 ºC.
Note: temperature affects the flow of cream and some other liquids.
Ice may interfere with product flow. Warm product flows faster.

8. Check the refrigeration temperature. Ice may interfere with product flow. To
adjust temperature, see page 14, 15.

9. Check to ensure the system is re-setting properly.
The volumes to be dispensed are pre-set electronically in our factory and are
pre-set to the specified amounts automatically each time the front valve door is
opened.
Follow this procedure to check to ensure the dispenser is re-setting:

a. make sure no product is spilled during the test by pinching off the

product delivery tube with a pinch clip or fork before you begin.

b. open the valve door by unscrewing the knob in a counter-clockwise

motion.

c. TR1 will be displayed in the LCD when the valve door is opened. A new
bag of product must be loaded to ensure proper volumes of

product are delivered.

ii. If the display does not show TR1 when the valve door is

opened, the reed switch is defective and must be replaced. Call
the SureShot Dispensing Systems® Technical Assistance
Center at 1-888-777-9990 or 1-902-865-9602 for assistance.

d. ensure the product delivery tube is inserted properly in the valve door.

e. close the valve door securely, by replacing the knob-screw.
Do not over-tighten the screw.

f. push a dispense button on the front door. If correct amount of product is
dispensed, the machine has re-set and is working properly. If correct
amount of product is not dispensed, call the SureShot Dispensing
Systems® Technical Assistance Center at 1-888-777-9990 or 1-902­ 865-9602 for assistance.
NOTE: Test the operation of all dispense buttons and test the amounts
dispensed by each.

Frost build up in the refrigeration
compartment

1. Check the temperature inside the refrigerated product compartment, to make sure

it is within the temperature range of 35 ºF to 40 ºF (1.6 ºC to 4.4 ºC). If the
dispenser is running cold, it could form ice.

2. If the dispenser has accumulated ice or frost at the top of the compartment, it is

best to remove it during a defrost cycle, which runs automatically and will be
indicated on the LCD display panel. Forming ice does not necessarily mean the
temperature of the product is too cold. If excessive ice or frost builds up, it should
be removed by hand during that defrost cycle.

3. Ice may be removed during a product change: turn off the dispenser.

Leave the door open for about 15 minutes to allow the ice to soften.
Remove the ice by hand.

4. If a temperature adjustment is required, follow the instructions on pages 14, 15. If

further assistance is required, contact the SureShot Dispensing Systems®
Technical Assistance Center at 1-888-777-9990 or 1-902-865-9602.
