INTRODUCTION

1.1 Description

Beverage-Air Refrigeration products, refrigerators and freezers, are distinctly designed to accommodate a
wide variety of food service needs and situations. Beverage-Air products are designed to keep
refrigerated products at 38 F, while frozen products are kept at 0 F for maximum safety and freshness.
Wine cabinets are set to run from 55° to 65°F

1.2 Glossary of Terms

Compressor - The compressor is the heart of the system. The compressor does just what its name
states. It compresses the low pressure refrigerant vapor from the evaporator and compresses it into a
high pressure vapor. The inlet to the compressor is called the “Suction Line”. It brings the low pressure
vapor into the compressor. After the compressor compresses the refrigerant into a high pressure Vapor,
the vapor is pumped into the “Discharge Line”.

Condenser Coil - The “Discharge Line” leaves the compressor and runs to the inlet of the condenser coil

located on top of the cabinet. Because the refrigerant is compressed, it is a hot high pressure vapor (as
pressure goes up – temperature goes up). The hot vapor enters the condenser coil and starts to flow
through the tubes. Cool air is blown across the outside of the finned tubes of the condenser coil (usually
by a fan or water with a pump). Since air is cooler than the refrigerant, heat moves from the refrigerant to
the cooler air (energy goes from hot to cold – “latent heat”). As the heat is removed from the refrigerant, it
reaches its “saturated temperature” and starts to condense (change states), into a high pressure liquid.

The high pressure liquid leaves the condenser coil through the “liquid line” and travels to the “metering

device”. Sometimes running through a filter dryer first, removes any dirt or foreign particles.

Defrost - The term is used to identify the function of a refrigerator or freezer to remove frost or ice from
the internal evaporator coil.

Differential - An increment between where the compressor turns on and off.
Setpoint - This is the refrigerator or freezer cut out temperature set by the operator. Prior to shipping,

refrigerators are factory preset at 35°F and freezers are factory preset at -4°F.

to the floor upon installation.

WARNING: UNIT MUST BE BLOCKED AND SECURED WHEN

REMOVING SKID

2.1 Receiving and Inspecting

Prior to shipping, all Beverage-Air products are factory tested for performance and thoroughly inspected
to ensure they are free of any defects. Upon receipt, carefully examine the unit for any damage that may
have occurred during shipping and delivery. Any damage, discrepancies, overages, or shortages should
be noted on the carrier’s Bill of Lading and a freight claim must be immediately filed with the carrier. If
damage is noted after receipt, contact the carrier’s local terminal and file a freight claim. In either case, IT
IS IMPORTANT THAT ALL ORIGINAL CARTONS, CRATES, AND INTERIOR PACKAGING MATERIAL
ARE SAVED UNTIL INSPECTION HAS BEEN MADE BY THE DELIVERING CARRIER

NOTE: If the unit is laid down for any reason, the fluids in the compressor will drain out. To
prevent damage to the unit it MUST be allowed to sit upright for a minimum of One (1) hour prior
to starting up unit.

2.2 Uncrating

* Tools Needed: ¾” box wrench, adjustable wrench, level, flat head screw driver, and box cutter.

1. Remove the cardboard top capping, all clear tape, and all staples including those at the b
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.

*Note: additional clear plastic protective wrap is applied directly to any product with a glass door.

3. Move unit as close to final position as possible before removing the skid.

4. Tip the unit forward and remove the skid. Remove the shipping bolts using the ¾” box wrench
while cabinet is held in one direction. Then repeat the process while the cabinet is held in the
opposite direction.

2.3 Placement

Consider the following when selecting a location for your cooler:

1. Clearance:

2. Floor Load: the floor on which the cooler is located must be even and level, free from
vibrations, and strong enough to support the combined weights of the unit and maximum
product load.

3. Ventilation

4. Power Outlet: Dedicated power outlet is located within 8 feet of length of cord.

5. Floor Drain: DD units require a floor drain to capture condensate and beer spillage

WARNING: unit must be blocked and secured prior to installing casters

2.4 Cooler Set-up for Units with Legs or Casters

1. Legs and casters must be screwed in by hand. Use the threaded holes located on the bottom
of the cabinet. None of the threads on the leg or caster stem should be visible once
screwed in. Once the caster cannot be turned any further, use the ¾’ box wrench to
tighten the nut in between the mounting plate and the wheel of the caster until snug.

2. Tilt the cabinet in one direction approximately 8” and block it securely with pieces of 2x4
lumbers or other suitable material.

3. Screw in the two accessible legs/casters

4. Repeat this procedure with unit secured in the opposite direction so as to access the
remaining legs/casters

2.5 Leveling, Bumpers and Shelves

2.5.1 Leveling:

Cabinets must be leveled when installed. Level should be measured on the headrail.

Failure to level your cabinet may result in door not sealing, closing correctly, or
condensed water draining not draining properly.

For cabinets with legs, rotate the foot of the leg with an adjustable wrench to achieve

desired height for leveling.

For cabinets with casters, leveling can be achieved by placing large washers in between

the ½’ stud and the holes located on the bottom of the case.

2.5.2 Bumpers:

Bumpers and screws are included in the zip lock bag.

Remove one screw frome each end of the top rear and discard screws. Attach the

bumpers in the same locations, using the longer screws provided.

Warning: Cabinet MUST NOT SHARE A RECEPTACLE with another piece of equipment

WARNING: DO NOT clean with any product containing bleach or ammonia. Rinse

with clean water before drying with clean cloth.

2.6 Cabinet Cleaning

Prior to use, the interior and exterior surfaces of the cabinet should be cleaned thoroughly with warm
water, mild detergent, and a soft cloth. Apply with a dampened cloth and wipe in the direction of the metal
grain. Then allow to air dry with the doors open. Only use a clean soft cloth. See detailed cleaning
instructions in the Preventative Maintenance section below.

2.7 Electrical supply

115 volt self-contained units are provided with a 15 or 20 amp power chord with plug that is shipped
coiled on top of the cabinet. The power cord is equipped with a three prong (grounding) plug which is to
be used in an appropriately rated and dedicated three prong (grounding) receptacle.

*NOTE: have a wall outlet checked by a qualified electrician for polarity and proper grounding
prior to plugging in the power cord.

For units not provided with a power cord, the electrical connection should be made by a qualified
electrician and in accordance with local electrical codes. The electrical requirements are located on the
rating (or data plate) located on the left hand side of the interior of the cabinet. Use of a dedicated circuit
with separate grounding wire is required.

2.8 Controller

The controls are designed for the refrigeration units to maintain a product temperature of 38 F and the
freezers to maintain a product temperature of 0 F. See section 3.1 for control display information.

2.9 Installation Checklist

After the cabinet has been installed, leveled, and cleaned as described above, refer to the following check
list:

 Check for proper electrical hook-up.
 Check that all clearances are in line with the aforementioned guidelines.
 Check that cabinet is level.

2.10 Installation of Draft Arms – DD, BM Models
To install draft arms, first place rubber washer over draft arm mounting holes in cabinet top and put beer
line connector down through the hole. Next, 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 will assure that the air hose remains in place at all times to
keep the beer faucet cold.

2.11 CO2 Line Routing
To retain complete mobility of the BarMobile, the accessory CO2 tank (Up to five lb. size) can be placed in
the cooler. For permanent installations of DD Models a “knockout’ plug has been provided through which
the CO2 line can be extended.

UNIT OPERATION

3.1 Sequence of Operations

When the cabinet temperature exceeds the upper control limit, the compressor and condenser fan are
energized to cool the unit down to the lower control limit. The evaporator fan(s) run all of the time.

To raise or lower the cabinet temperature, toggle the up/down arrows on the right hands side of the
control to the desired set point.

* NOTE: Once the unit has been started and reaches proper storage temperatures, it may be

loaded with product. For proper energy efficiency and airflow we recommend a minimum1”
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.

12

809-119A Rev C

PREVENTATIVE MAINTENANCE

4.1 Daily, Exterior

1 - Clean the surface with a sponge and dilute mild detergent. Use a non-abrasive cleaner that

does NOT contain chlorine.

2 - Rinse with clean water before drying with clean soft cloth.

3 - Polish with a soft cloth, wiping with the grain of the metal.
4 - Once a week wipe with a film cutting agent or stainless steel polish to maintain finish.

4.2 Weekly, Interior

1 - Remove all food, food related items, and shelves.
2 - Disconnect power to the cabinet at the main power supply circuit breaker
3 - Remove loose food particles from interior floors, walls, and ceiling
4 - Scrub all interior surfaces and door gaskets with a warm (100-120F) detergent solution
and a soft nylon bristle brush
5 - Rinse with clean water and allow to air dry
6 - Re-install the shelves
7 - Restore power to the cabinet by resetting main power supply circuit breaker
8 - Return food to the cabinet when temperature indicator displays safe food temperature

4.3 Monthly, Condenser

The condenser coil is located right behind the front grille on top of the cabinet. It should be
inspected once a month and cleaned as required. Vacuum clean all surfaces of the condenser.
Make sure no fins are bent or damaged in the process. If there are bent fins, carefully straighten
them so that air can flow 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.

4.4 Periodic, Gaskets

1 Visually inspect the door gaskets for a tight seal on all four sides. Inspect for any type of

damage such as rips, tears, stiffness, or cracks.
2 If any such condition exists, the magnet will not seal and the gasket will need replaced.
3 Cleaning the gasket requires the use of mild dish detergent and warm water.
4 Next, thoroughly rinse and dry the gasket.

4.4 Condensate Drainage and Cleaning

1 For BB models the condensate drains into a pan located just below the condensing

compartment grille. On the BM models the condensate drains into a pan beneath the
cabinet and waste beer drains into a plastic jar inside the cooler which must be cleaned
periodically. The condensate pans should be cleaned periodically.

2 For DD Models 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 floor drain system for proper disposal of
condensate and spillage.

4.5 Faucet Cleaning

The faucet should be cleaned weekly. Disassemble with the provided spanner wrench clean with hot
water and detergent.
