CHECK FOR SHIPPING DAMAGE
Prior to leaving the factory, each cabinet is throughly inspected and performance tested to assure proper operating temperatures.
Check the crate thoroughly for signs of shipping damage
. If external damage exists, internal damage is also probable. Uncrating should be done while the carrier´s representative is present. Otherwise, the equipment should be uncrated as soon as possible, preferably within five (5) days.
The manufacturer is not responsible for in-transit damage and the
consignee must file any required damage claims directly with the carrier.
If the damage is severe and obvious, write a brief description of the evidence on the carrier’s delivery receipt, and above the carrier representative’s signature. Call the distributor or dealer immediately, indicating that the cabinet was damaged.
CAUTION: Risk of Fire or Explosion due to Flammable Refrigerant Used.
Follow Handling Instructions Carefully in Compliance with U.S. Government
Regulations.
If no obvious crate damage is present, within two hours of receiving the cabinet from the carrier, remove the packaging to inspect for concealed
damage.
1.
If concealed damage is found, call the carrier immediately,
save all crating materials
, and file the necessary freight claim with the carrier.
Check for accesories:
Check that the shelves are inside the refrigerator,
including the four clips or supports for each shelf.
HANDLING THE CABINET
1. Always move the unit in an upright position. Do not set it on its side or upside down as you may damage the cabinet and spill the compressor oil.
2. I f lifting the unit, hold it from its base. It is recommended to use a dolly.
3. D o not let the unit fall abruptly.
4. P lace the cabinet on a surface solid enough to prevent vibration and strong enough to support the combined weight of the cabinet and the product load.
Quick guideline: Estimate 35 pounds per cubic foot of storage space.
5. C abinets should never be placed in front of windows or glass doors where sunlight will be in direct contact with the units. If a cabinet is located near a window or glass door, provide an adequate shade to block the sun´s rays.
6. Ambient temperature must be between 60°F and 86°F. Low ambient temperatures below 50° F are as harmful as high ambient temperatures.
Extreme temperatures will definitely affect the performance of the cabinet.
7. F ailure to properly level the cabinet could hinder proper drainage and door operation. Leveling legs are provided with the cabinets. Level the cabinet by using the adjustable portion of the leveling legs as needed.
8. C learance: Leave a space of at least 8” between the back of the cabinet and the wall to provide adequate air circulation of the unit compartment.

LEVEL THE CABINET
The base of the refrigerator has heavy duty leveling legs underneath so the cabinet may be leveled appropriately and to allow room to clean beneath the cabinet.
Level the cabinet front to back and side to side with a level by using the adjustable portion of the leveling legs. This is vey important to insure proper draining and door operation.
To lower, turn clockwise
Leveling leg
To raise, turn counterclockwise
ELECTRICAL INSTALLATION
Each unit requires a 110 Volt individual, properly grounded branch circuit with a 3 prong grounding type receptacle, protected by a 15 or 20 Amp circuit breaker or time-delay fuse.
Electrical installation must be in accordance with National Electrical Codes
and local ordinances.
WARNING
The power cord has a ground prong.
Do not under any circumstance cut
or remove the ground prong from the cord. Removal of ground prong
invalidates product warranty.

START UP THE COOLER
1.
Plug in the electrical cord of the unit to a wall outlet, following the recommendations about electrical installation in this manual.
2.
Let the cooler run with no product load for 2 hours, or let the com
-
pressor complete three on/off cycles to assure that the temperature
inside is appropriate for the products before loading them into the refrigerator.
3.
When placing products in the cooler, you should leave small gaps between one and the other to assure free circulation of air inside
the cabinet.
4.
Do not leave the door open for extended periods of time, to avoid
increased temperature of the products.
5. Do not unplug your cooler during the night, since when you turn it back on during the day the electrical consumption will increase.
The temperature of a cooler should be between 34°F to 40°F.
These coolers are provided with a versatile electronic thermostat that allows to cool different beverages.
This controller has a feature to reduce energy consumption during the closing hours of your locale. To activate this feature press the ES button on the controller. In this refrigerator, the Energy Saving mode has been programmed to turn off the lights for one hour, or until the door is opened.
The Energy Saving mode can also be deactivated by pressing the ES button, which will turn the lights back on.
