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.
1.2 Glossary of Terms
Compressor - The compressor is the heart of the system. The compressor does just what it’s 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 it’s “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.

INSTALLATION
I
WARNING:
WARNING: If it is necessary to move the cooler after removal from the skid,
remove all doors and carefully push the unit at a point of no more than 36” from
the bottom to avoid damage. It is an NSF requirement that all rollin-in/roll-thru units
be sealed to the floor upon installation.
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. First, remove the cardboard top capping, all clear tape, and all staples including those at the b
bottom of the cardboard carton and skid.
2. Next, 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. Then, move unit as close to final position as possible before removing the skid.
UNIT MUST BE BLOCKED AND SECUREDWHEN
REMOVING SKID
4. Finally, 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: 3” between the back of the cabinet and the wall
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.

INSTALLATION
2.4 Cooler Set-up for Reach In units
With Legs or Casters
WARNING: unit must be blocked and secured prior to installing 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 Leveling, Bumpers and Shelves
2.5.2 Shelves:
All cabinets with shelves are supplied with pilasters and shelf clip supports. Shelves are
easily installed by inserting the shelf support clips into the pilasters so that they fit
tightly.
Adjust the shelf so that the smaller fill wires run from front to rear and the shelf frame
wire rest the shelf on the clips.

2.6 Cabinet Cleaning
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.
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.
* 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.

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.
