UNPACKING AND SET UP
CAUTION
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. Cut the stretch wrap along a corner post and remove
the cardboard top capping and the corner posts.
2. Discard stretch wrap and any cardboard that will not
be recycled.
Note: additional clear plastic protective wrap is
applied directly to any product with a glass door.
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.
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.
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
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.
Leveling:
Cabinets must be leveled when installed. Level should be
measured on the headrail.
Note: If no casters, legs or levelers are to be installed,
the oor below the equipment must be level
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.
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.

1. Determine the proper location for the shelf clips.
The reference numbers on the pilaster can serve as a
guide to ensure all clips are properly located.
2. Insert the top tab of the shelf clip into the desired
hole of the pilaster. The retaining tab MUST be facing
up as shown.
3. Rotate the clip downwards and insert the bottom tab
into the matching hole in the pilaster. The clip may
need to be squeezed slightly during installation.
4. Install all remaining clips.
5. Install shelves onto clips with the product retention
bar facing up. Be careful not to dislodge clips during
installation.
6. Place shelves so that the retaining tab on the clip
captures the shelf as shown.
7. Conrm that the shelf is resting on ALL 4 clips and
that the clips are securely attached to the pilasters.
8. Improper shelf clip installation could cause the shelf
and / or the product on it to fall, resulting in damage
to the unit and possible bodily injury.
9. Do NOT overload the shelves. The unit is designed to
use all shelves that are supplied in an equally spaced
manner. Contact Beverage-Air customer service if
fewer shelves or a dierent conguration to ensure
shelf overloading will not occur.

This is a cord-connected unit, and must be connected to its own dedicated power 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 of the
top area, 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.
Door Reversal Instructions
1. Remove hinge cover.
2. Remove door from the unit including the hinge
mounting brackets
3. Remove white hole covers from the side of the door
opening you would like the hinges to be located (do
not throw away).
4. On the bottom of the door the same hole plugs are
present and need to be removed.
5. Take the hole plugs and insert them into the screw
holes where the hinges were originally located on the
unit.
6. Install the hinge bracket upright on the unit. The
thick portion of the hinge bracket should be on the
bottom as you mount them.
7. The door portion of the hinges need to be removed
and rotated 180 degree and remounted.
8. Install the hole plugs that were removed from the
bottom of the door into the holes where the handle
was rst mounted.
9. Slide door back into position and gently lower into the
white pivot cam.
10. Replace hinge cover.

FOR THE SERVICE TECH - R290
Refrigeration service should only be attempted by a trained trade professional certied to work on R290 systems.
Here are some critical service items.
This list does not qualify anyone to service the unit. It is a
reminder and checklist for the service tech. Keep these in
mind for :R290 service
• Wire nuts are NOT to be used when changing an
electrical part.
• The switches in this product are sealed, only exact
replacements may be used.
• The process tubes are to be used for service access.
• Cut out (with tubing cutter) refrigeration components
that are to be replaced. Do NOT un-braze.
• Because R290 can be vented into the air during
service, the venting MUST be in an area free from
ame or spark. It must be near an opened window or
door.
• A sign noting service of a system containing propane
must be attached to the unit during refrigeration
service.
• A combustible gas leak detector must be used to
inform anyone in the area when propane is present in
the air.
Other Information:
Evacuation: It is critical that a refrigeration system be
leak free and internally dry. A thorough evacuation with
a good vacuum pump with a micron gauge attached is the
only way to ensure that the system is dry and ready for a
charge of refrigerant.
Charging: The system is critically charged and the proper
type and amount MUST be weighed in.
Overcharge symptoms: Unit will cool properly but
the suction line temperature will be unusually cold.
Compressor run time will be longer than normal.
Undercharge symptoms: Long run time, poor cooling and
a hot compressor dome are the main symptoms of an
undercharge.
