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
- Temperature control set at No. 4 position gives refrigerators an approximate temperature of 35°F.
Allow unit to function several hours, completely cooling cabinet before changing the
control setting.
- 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!

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.
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.

Regular Maintenance
Cleaning the Condenser Coil
- For efficient operation, it is important that the condenser surface
be kept free of dust, dirt, and lint.
- We recommend cleaning the condenser coil and fins at least
once per month.
- Clean with a soft brush and vacuum cleaner.
Brush the condenser fins from top to bottom, not side to side.
- After cleaning, straighten any bent condenser fins with a fine comb.
Cleaning the Fan Blade and Motor
-If necessary, clean the fan blades and motor with a soft cloth. If it is necessary to wash the fan
blades, cover the fan motor to prevent moisture damage.
Cleaning the Interior of the Unit
- When cleaning the cabinet interior, use a solution of warm water and mild soap.
- Do not use steel wool, caustic soap, abrasive cleaners or bleach that may damage the stainless
steel surface.
- Wash door gaskets on a regular basis, preferably weekly. Simply remove door
gasket from the frame of the door, soak in warm water and soap for thirty (30) minutes, dry with soft
cloth, and replace.
- Check door gaskets for proper seal after they are replaced.
- Periodically remove the shelves and pilasters from the unit and clean them with mild soap and
warm water. To remove the pilasters, first remove the shelves and shelf brackets. Then, simply lift the
pilaster up and out.

Stainless Steel Equipment
Care & Cleaning
Stainless Steel Destroyers:
There are three basic things which can break down your stainless steel’s outer defenses and allow
corrosion to develop.
1. Scratches - Wire brushes, scrapers, and steel pads are just a few examples of items that can be
abrasive to stainless steel’s surface.
2. Deposits - You may have hard or soft water depending on what part of the country you live in.
Hard water can leave spots. Hard water that is heated can leave deposits if left to sit too long.
These deposits can cause the outer layer to break down and rust your stainless steel.
All deposits left from food prep or service should be removed as soon as possible.
3. Chlorides - Present in table salt, food, and water, chlorides eat away at the protective layer
surrounding stainless steel. Household and industrial cleaners are the worst types of chlorides.
Recommended Cleaners:
1. Noble Chemical CitraKleen All-Purpose Citrus Cleaner & Degreaser
Heavy duty citrus cleaner removes tough grease, dirt, and mineral build-ups without damaging
stainless steel. Its natural citrus solvent leaves behind a pleasant orange scent.
2. Noble Chemical Spiffy Shine Metal Polish
An oil-based, all-metal polish that delivers a brilliant, mirror-like shine in no time! Its gentle
cleansing agents (no harsh abrasives) easily penetrate and remove grease, film, water spots,
and fingerprints from stainless steel. This all metal polish is safe to use on fixtures, lamps,
chafing dishes, serving pieces, cookware, table accessories, sinks, hoods, refrigerators, freezers,
stoves, flatware, and faucets. Spiffy Shine gives your metal a bright appearance and keeps it
that way by resisting smudging.
3. Noble Chemical Excel Stainless Steel Cleaner/Metal Polish
Advanced water-based formula cleans like an oil-based product but without the oiliness or
flammability. This lemon-scented stainless steel and metal polish cuts through grease and oil
while leaving a protective shine.
CAUTION: Do not use any steel wool, abrasive, or chlorine based
products to clean stainless steel surfaces.

User Manual
Preventing Rust on Stainless Steel:
1. Use the Correct Cleaning Tools
Use non-abrasive tools when cleaning. The stainless steel’s outer layer will not be harmed by soft
cloths and plastic scouring pads.
2. Clean Along the Grain
Polishing lines or grain are visible on some stainless steels. Always scrub parallel to these visible
lines on stainless steel using a plastic scouring pad or soft cloth. If no lines are visible, use a soft
touch with a soft cloth or plastic scouring pad.
3. Use Alkaline, Alkaline Chlorinated, or Non-Chloride Containing Cleaners
While many traditional cleaners are loaded with chlorides, commercial suppliers are providing
an ever increasing choice of non-chloride cleaners. One of the best is Noble Chemical Excel
Stainless Steel Cleaner. If you are not sure of your cleaner’s chloride content, contact your
cleaner supplier. If they tell you that your present cleaner contains chlorides, ask if they have an
alternative. Avoid cleaners containing quaternary salts as they can attack stainless steel, causing
pitting and rusting.
4. Water Treatment
To reduce deposits, soften the hard water when possible. Installation of certain filters can remove
corrosive and distasteful elements. Salts in a properly maintained water softener can be to your
advantage. Contact a treatment specialist if you are not sure of the proper water treatment.
5. Maintaining the Cleanliness of Your Food Equipment
Use cleaners at recommended strength (alkaline, alkaline chlorinated or non-chloride).
Avoid build-up of hard stains by cleaning frequently. When boiling water with your stainless steel
equipment, the single most likely cause of damage is chlorides in the water. Heating any cleaners
containing chlorides will have the same damaging effects.
6. Rinse & Dry
When using chlorinated cleaners, you must rinse and wipe dry immediately. It is better to wipe
standing cleaning agents and water as soon as possible. Allow the stainless steel equipment to
air dry. Oxygen helps maintain the passivity film on the stainless steel.
7. NEVER USE HYDROCHLORIC ACID ON STAINLESS STEEL
8. Regularly Restore/Passivate Stainless Steel
