PROPER DISPOSAL OF EQUIPMENT DANGER!
RISK OF CHILD ENTRAPMENT SAFETY
!
Proper Disposal of the Refrigerator
If you are getting rid of an old refrigerator, please follow the below instructions to help prevent a
terrible accident.
- Remove the doors.
- Leave shelves in place to prevent children from easily climbing inside.
Do not allow children to climb, stand or hang on the shelves in the cooler. They could damage the

Electrical Instruction
When using electrical appliances basic safety precautions should be followed:
- This cooler must be properly installed and located in accordance with the installation
service representative.
- Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this
or any other appliance.
- Unplug the unit from the electrical outlet before cleaning or making repairs.
- Setting the temperature controls to the (0) zero position does not remove all power.
Please ensure that the required voltage for the compressor is being supplied at all times.
If the voltage is unstable, please select a suitable automatic voltage regulator.
- All units should be plugged into a grounded and properly-sized electrical outlet with appropriate
overcurrent protection. Please refer to the electrical requirement on the nameplate. The power
cord of this cooler is equipped with a grounding plug which fits a standard grounding wall outlet
to minimize the possibility of electrical shock hazard.
Standard Plug: NEMA 5-15P
If the outlet is a standard 2-prong outlet, it must be replaced with the properly
grounded wall outlet. NEVER USE AN ADAPTER PLUG!
- Have the wall outlet and circuit checked by a qualified electrician to make sure the
outlet is properly grounded. Check the incoming voltage with a voltmeter.
- DO NOT USE EXTENSION CORDS. The use of extension cords to connect the cooler will void
warranty. The unit must be close enough to the electrical outlet so that extension cords are
never used.
- The cooler should always be plugged into its own dedicated circuit with a voltage rating that
matches the rating plate. This provides the best performance and also prevents overloading
wiring circuits which could become a fire hazard from overheated wires.
- Never unplug your cooler by pulling on the power cord. Always grip the plug firmly and pull
straight out from the outlet.
- Immediately repair or replace all power cords that have become frayed or otherwise damaged.
Do not use a power cord that has cracks or abrasion damage along its length or at either of
its ends.
- When moving the cooler away from the wall be careful not to run over or damage the power cord.
It is strongly recommended that any servicing be performed by an
authorized service representative.
CAUTION: Low or high voltage can damage the refrigeration unit.

Startup
- Dial temperature controls set at the no. 4 position gives refrigerators an approximate temperature
of 35°F. Digital temperature controls are programmed to operate between 33°F and 40°F with no
adjustments. Allow unit to function several hours, completely cooling the cabinet before changing
the control settings.
- Excessive tampering with the control could lead to service difficulties. Should it ever become
necessary to replace temperature control, be sure it is ordered from your Avantco dealer or
recommended service agent.
- Good air flow in your unit is critical. Be careful to load product so that it neither presses against
the back wall, nor comes within four inches of the evaporator housing. Refrigerated air off the coil
must circulate down the back wall.
Recommendation:
Before loading product, we recommend you run your Avantco unit empty for 2-3 days. This allows
you to be sure the electrical wiring and installation are correct and no shipping damage has
occurred. Remember, the Avantco factory warranty does not cover product loss!

Your new refrigerator or freezer is already factory-set to run at optimum
temperatures for food safety and should require no adjustments.
Refrigerators are set to cycle between a minimum temperature of 33 degrees
Fahrenheit and a maximum temperature of 40 degrees Fahrenheit.
Freezers are set to cycle between a minimum temperature of -5
degrees Fahrenheit and a maximum temperature of 2 degrees
Fahrenheit.
Drain Instructions
On direct draws, the drain is located at the front of the cabinet.
(UDD1 & UDD1S drain into a bottle located inside the unit)
To plumb in the drain, connect ½” PVC pipe to the barbed fitting supplied with the unit.
If you would prefer to drain the beer inside the unit (for mobility or where a drain can’t be found):
- Use a screwdriver to remove the drain bracket.
- Pull the drain hose so that it is inside the unit.
- Attach a bottle to the drain hose inside the unit.
- Plug the created hole at the bottom of the unit

User Manual
Adjusting the temperature changes the minimum temperature your unit will run at. Your unit will not
run constantly at this setting. To change it, follow these instructions:
Digital Control Units
• Hold “SET” for 1 sec. The display will flash the current minimum temperature.
• Use the arrow buttons to adjust the minimum temperature you want it to run at.
• Press “SET” again to save your settings
Always remember to calculate the differential if you change the minimum temperature setting. The
cabinet temperature will fluctuate up to +7 degrees over your set minimum temperature as the
compressor runs and shuts off. Setting the temperature too high will result in unsafe maximum
temperatures and possible health code violations.
Temperature
Correct temperature is a key factor to consider when storing and dispensing draft beer.
Too cool or too warm may cause flavor loss and dispensing problems.
Hints on Controlling Temperature
- Keep a thermometer handy.
- Monitor temperature of draft both inside your cooler and at the tap.
- Keep the cooler door(s) closed as much as possible to avoid temperature fluctuation.
- Regular maintenance will help identify potential problems before they become definite problems.
Pressure
Dispensing pressures differ according to:
- The type of draft dispensing system
- The length of draft dispensing line
- The actual draft product
- The temperature of the draft product
- The pressurizing agent: Compressed air, CO2, or specially blended gasses.
Hints on Maintaining Correct Pressure
- Research which pressurizing agent works best with your product and why.
- Monitor your regulators to ensure applied pressure remains constant.
- Keep equipment in good repair.
Tapping
- Do not agitate the kegs unnecessarily.
- If excessive agitation occurs, allow kegs to settle for 1-2 hours before tapping.
- Prior to tapping the keg, ensure that all beer faucets in the serving location are in the off position.
- Completely remove the dust cover (identification cap) from the keg.

User Manual
NOTE: In models UDD1 & UDD1S, the CO2tank (up to 5 lbs. in size) can be placed inside the cooler
to maintain complete mobility
CAUTION
CO2 tanks are potentially dangerous because of the pressure they contain. If you are unfamiliar with
their use or the use of a CO2regulator, seek information from your local distributor, or beverage man
before proceeding.
Storage & Handling
Draft beer should be treated as a food product. In most instances draft beer is not pasteurized. It is
very important that you store and handle it properly. Follow these steps to ensure the highest quality,
safety, and consumer satisfaction.
- Draft beer should be immediately stored in a refrigerated cabinet.
- Draft beer products have a recommended shelf life. If you have questions regarding the shelf life
of any of your draft products, please consult with your supplying depot or respective brewery
representative.
- Kegs should be stored separately from food products. If your cooler is used to refrigerate draft
and food products, it is very important that the food not be stored near or on the kegs.
- Keg storage and dispensing areas should be kept clean to prevent any possibility of contaminating
your products.
Knockout CO2Installation
These is the recommended procedure for
installing a remote CO2container in your Avantco unit.
1. Remove black knockout plug with pliers. (See images below for plug locations)
2. Use drill with 1/2” bit to bore a whole straight back through wall into compressor compartment.
3. Snake CO2line through hole, down and around, exiting behind rear caster underneath grill.
4. Seal hole around CO2line with silicone sealer to prevent cold air leakage.
*Depending on setup and amount of kegs, a CO2manifold may be needed.
Tools:
- Pliers
- Power Drill
- Silicone Sealer
- 1/2” Drill Bit
