UNPACKING AND SET UP
Carefully inspect the shipping carton for damage. This is the only time that shipping damage may be claimed. If damage is
suspected, open the carton immediately and, if there is damage, retain the carton and contact the shipper to make a claim.
Do NOT contact the manufacturer.
Uncrating
Tools Needed: ¾” box wrench, adjustable wrench, level,
at head screw driver, and box cutter.
1. Remove the cardboard top capping, all clear tape,
and all staples including those at the bottom of the
cardboard carton and skid.
2. Start from the top of the carton. Using the box cutter,
carefully make one continuous cut to the bottom of
the skid. Remove cardboard carton and discard.
3. Move unit as close to nal position as possible before
removing the skid.
Note: The skid must be removed before the casters or legs
can be attached.
Do NOT tip unit on its front or sides. If tipped onto the
back, unit must not be started for 3 hours.
Installation of Draft Arms – BM Models
Place rubber washer over draft arm mounting holes in
cabinet top and put beer line connector down through the
hole. Secure each draft arm with the four bolts provided.
Place air hose clip over beer line and insert one inch
plastic hose in draft arm being careful not to disturb
insulation. Remove top cover of draft arm and attach
air hose clip to the ¼” stainless steel elbow at faucet
connection. Replace top cover. This clip assures that the
air hose remains in place to keep the beer faucet cold.
CO2 Line Routing
For permanent installations a “knockout’ plug has been
provided through which the CO2 line can be extended

User Manual for DD Refrigerators Beverage-Air
Rev. 06/20 Beverage-Air 9
Skid Removal and Caster Attachment
Tip the unit forward and remove the skid.
Risk of personal injury.
Unit must be securely supported
while attaching casters or legs.
WARNING
1. Remove the shipping bolts using the ¾” box wrench while
cabinet is held in one direction. Repeat the process while
the cabinet is held in the opposite direction.
2. None of the threads on the leg or caster stem should
be visible once screwed in.
3. Tilt the cabinet in one direction approximately 8” and
block it securely with pieces of 2x4 lumber or other
suitable material.
4. Thread the stem casters or legs into the ½ -13 holes in
the bottom of the cabinet. Tighten by hand as much
as possible. Some models may already have levelers
installed. If so, then the levelers will need to rst be
removed and discarded.
5. Once the caster or leg cannot be turned any further,
use a 3/4 inch wrench to tighten the nut in between
the mounting plate and the wheel of the caster until
snug.
6. Repeat this procedure with unit secured in the
opposite direction so as to access the remaining legs/
casters/levelers.
7. If plate casters or legs are installed instead of stem
casters or legs, then repeat step 3 above and secure
the plate with either #14 AB screws, or ¼-20 screws,
depending upon which are required.
8. If levelers are employed, then repeat step 3 above and
thread the leveler in place. Then repeat step 6.
Leveling:
Cabinets must be leveled when installed. Failure to level
cabinet may result in door not sealing, closing correctly, or
condensed water draining not draining properly.
Leveling can be achieved by placing large washers in
between the caster's ½’ stud and the holes located on the
bottom of the case.
Do NOT loosen casters to level
the cabinet. Casters MUST be
tightly secured to cabinet for full
strength.
Install or attach any accessories that will be used
Remove any plastic covering the stainless steel.

This is a cord-connected unit, and must be connected to its own dedicatedpower supply. Check the dataplate on the
machine to conrm the voltage and per the dataplate use the correct fuses or HACR circuit breakers.
Note: Do not connect to GFI / GFCI outlets. Connection to that type of outlet can result in product loss due to unsafe
cabinet temperature when GFI device trips from moisture.
Power Cord
This 115 volt model is equipped with a cord and 5-15P plug.
If the power cord becomes damaged, it must be replaced
with the identical cord.
Follow All National and Local Codes
This unit must be grounded. Do not use extension cords
and do not disable or by-pass ground prong on electrical
plug.
Initial Start Up
Plug the power cord into the proper power supply.
The cabinet will soon begin to blow warm air out, and cool
air will ow from the inside blower.
The cabinet temperature has been set at the factory and
should not need adjustment, however if it was changed,
the standard setting is 38º F.
Cautions
Care must be taken whenever moving or servicing the
unit. The refrigerant is contained in a sealed system, but if
released it may be ammable.

Operation is simple, just keep it connected to the correct
power supply and the refrigerator will maintain the
internal temperature it has been set to. Keep the door
closed as much as possible to avoid unnecessary run time.
NOTE: Once the unit has been started and reaches proper
storage temperatures, it may be loaded with product.
For proper energy eciency and airow we recommend
a minimum 1” clearance between product and side
walls, 4” clearance between product and ceiling, and 1”
clearance from the bottom of the unit. No provision is
made in the cabinets to quickly pull a keg of beer down to
temperature. Best results are obtained when a pre-chilled
keg is used. Otherwise it can take several hours to reduce
the keg to the desired temperature.
The controller displays the current internal temperature.
Adjusting the set temperature lower will NOT cause the
system to lower the temperature faster. When on, the
refrigeration system is always operating at maximum.
The temperature was set at the factory at 38ºF, but
you can adjust it to your own selected temperature. 30
seconds after adjustment, the display automatically
reverts to showing the current temperature.
The Refrigerator will automatically defrost as needed,
there is no set time for defrost. Push and immediately
release the "melting" or defrost button for a manual
defrost.
Note: Holding the defrost button in too long will shut the
controller o.
The internal fan will be on when the compressor is on and
when the doors are closed.
The compressor and condenser fan motor will only be on
when the controller senses an increase in internal cabinet
temperature passed the set point.
If equipped with glass doors, holding the SC button in will
turn the cabinet light on or o.

CLEANING AND MAINTENANCE
Cleaning Schedule:
Cabinet
Daily wipe down
Weekly interior
Condenser coil
Quarterly cleaning
Gaskets
Daily inspection, check
that hinges are tight to
the cabinet.
Routine maintenance
Annually
Daily Exterior Cleaning
It is much easier to clean on a regular basis than to have to remove stains once they have built up.
1. Wash with a clean sponge and a mild detergent that
does not contain chlorine.
2. Rinse with clean water.
3. Dry with a soft cloth.
4. Polish with a soft cloth, wiping with the grain.
5. Wipe weekly with stainless steel cleaner.
Weekly Interior Cleaning
1. Remove all food, food related items and shelves. Store
the food at a safe temperature.
2. Disconnect power to the unit (unplug it or switch the
breaker o).
3. Remove all loose food particles from the inside walls,
oor, door liner and ceiling.
4. Scrub all interior surfaces and door gaskets with a
warm (100oF to 110oF) detergent solution and a soft
scrub brush.
5. Rinse with clean water and allow to air dry.
6. Return the shelves to the unit and secure them.
7. Restore power.
8. Return food to the unit when it has reached a safe
temperature.
Condensate Drainage and Cleaning
The condensate from the evaporator and spillage from the draft arm areas are connected together to a single hose which
exits the unit in the bottom front. This combined drain must be connected to a oor drain system for proper disposal of
condensate and spillage.
Faucet Cleaning
The faucet should be cleaned weekly. Disassemble with the provided spanner wrench clean with hot water and detergent.
It is recommended to follow the dispenser system cleaning guidelines found in the Draught Quality Manual which can be
found at, https://www.brewersassociation.org/educational-publications/draught-beer-quality-manual/

CAUTION Rotating fan blade can cause
personal injury.
Unplug unit from power supply
before beginning to clean
condenser
The condenser coil is located right behind the front grille on models with end mounted condensing units, and behind the
rear grille on the DD24HC model. It should be inspected once a month and cleaned as required.
1. Remove power from the unit.
2. Vacuum clean all surfaces of the condenser.
3. Some coils will have an extreme layer of dirt, dust and grease covering the exterior. This should be removed with a
wire brush, industrial vacuum or low pressure clean water before attempting to was with coil cleaner.
4. Make sure no ns are bent or damaged in the process. If there are bent ns, carefully straighten them so that air
can ow through the coils. Failure to keep the condenser coil clean will lead to poor performance, excessive power
consumption and compressor failure and may result in loss of property. Failure to keep the condenser coil clean may
void the limited warranty.
Chemical Cleaning
1. Remove power from the unit.
2. A chemical condenser cleaning can be extremely messy so it is good practice to take the unit to a low trac area or
outside to do the cleaning whenever possible.
3. Remove cover grille.
4. Slide out condensing assembly if necessary.
5. Using the directions on the coil cleaning container, mix the cleaner and water into your sprayer.
6. Starting at the top with the tip about 6 inches away, begin spraying down the coil.
7. Spray side to side then go down to the next section of the coil. Repeat this until the coil is saturated.
8. Allow cleaner to soak into the dirty coil for a few minutes and then begin to rinse the coil.
9. Clean with a SMALL amount of water pressure. Too much pressure could cause the protective ns to fold over further
