AC10-PC LIQUID DISPENSERS - OPERATIONS
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.
Operating the dispenser is a simple two-step process:
1. Place cup under the product delivery tube.
2. Press button for the desired quantity of dairy product.
Safety Precautions
• Always plug the dispenser into an approved electrical outlet.
• The dispenser includes a microcontroller and must be operated on
grounded electrical wiring at all times.
• Unplug the dispenser from its electrical source before servicing.

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.
Caution: Keep the dispenser level at all times. Do not tip the dispenser while it is operating. Tipping will damage the
compressor and prevent proper operation of the refrigeration system.

5. TECHNICAL SERVICE
Leveling Dispenser
•The dispenser must be placed on a level surface or leveled by adjusting the legs. The dispenser must be
level to dispense accurate quantities and to ensure proper functioning of the refrigeration system. Not all
dispensers have adjustable legs. Some models have plastic feet, which are not adjustable.
•Do not remove the legs or 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 or feet at the four corners of the bottom of the dispenser are in place. Some dispenser models
have adjustable legs and these legs are secure even though they may appear to be loose. If one has
loosened during shipping, re-tighten it.
•Removal of the legs automatically voids the Warranty.
1. Place the dispenser on the countertop.
2. Level the dispenser:
For dispensers with plastic feet: level the countertop.
For dispensers with adjustable legs: Adjust the legs by hand-turning them slightly until the dispenser is level.
•To ensure the dispenser is level, place a bubble level on the top of the dispenser to guide you during the
adjustments.
•Do not allow the dispenser to be tilted backwards.
