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: 12 " box wrench, adjustable wrench, level, flat 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.

1. Move unit as close to final 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.

1. Thread the stem casters or legs into the 12 -13 holes in the bottom of the cabinet. Tighten by hand as much as possible.
2. 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.
3. Repeat this procedure with unit secured in the opposite direction so as to access the remaining legs/casters
4. 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 12 -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 floor below the equipment must be level

Failure to level your cabinet may result in door not

SHELF INSTALLATION

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. Confirm 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 different configuration to ensure shelf overloading will not occur.

Adjusting Spring Tension on ClearCool®3000 & ClearCool®3100

The amount of tension used on the self-closing bottle slider doors can be decreased or increased by relocating the spring retaining grommet and self-drilling screw.

1. Hold door in open position to expose spring, grommet and screw in the header. Open only as far as required to keep the amount of tension to a minimum.

ELECTRICAL

This is a cord-connected unit, and must be connected to its own dedicated power supply. Check the dataplate on the machine to confirm 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 flow 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 38^ F.

Cautions

Care must be taken whenever moving or servicing the

1. Remove white hole covers from the side of the door opening you would like the hinges to be located (do not throw away).
2. On the bottom of the door the same hole plugs are present and need to be removed.
3. Take the hole plugs and insert them into the screw holes where the hinges were originally located on the unit.
4. Install the hinge bracket upright on the unit. The thick portion of the hinge bracket should be on the bottom as you mount them.
5. The door portion of the hinges need to be removed and rotated 180 degree and remounted.
6. Install the hole plugs that were removed from the bottom of the door into the holes where the handle was first mounted.
7. Slide door back into position and gently lower into the white pivot cam.

USING THE UNIT - DANFOSS CONTROLLER

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 doors and / or drawers closed as much as possible to avoid unnecessary run time.

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 38' F, 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 off.

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 off.

FOR THE SERVICE TECH · R290

Refrigeration service should only be attempted by a trained trade professional certified 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 flame 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.
