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.
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. If lifting the unit, hold it from its base. It is recommended to use a dolly. 3. Do not let the unit fall abruptly. 4. Place 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.
REMOVE THE CRATE AND SKID 1. Remove the external packaging (corrugated board and plastic wrapping). Check for concealed damage. If any damage is identified, immediately forward a complaint to the transportation company. 2. Move the cooler the closest possible to its final location, before removing the skid. 3. Using a screwdriver remove the screws that fix the skid to the cooler.
To install casters: Casters are supplied as optional equipment. Only use genuine casters or the base of the cooler might suffer damages. When installing the casters it is important to hand tighten securely against the base rail reinforcement assembly (see image). The top edge of the caster must make firm contact with the reinforcement assembly. Base rail Caster Hand-brake NOTE: Casters with hand-brakes must be placed in FRONT of the unit.
ELECTRICAL INSTALLATION 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. Ground prong NEVER USE AN ADAPTER PLUG! Because of potential safety hazards under certain conditions, we strongly recommend against the use of an adapter plug. Do not plug in the electrical cord of the refrigerator to an electrical outlet that is used by other appliances. 14 Do not use extension cords.
INSTALLING THE SHELVES Shelves and shelf clips (4 clips per shelf) are packed inside the cabinet prior to shipment. After selecting the appropriate spacing inside the cabinet, install shelf clips by inserting top of clip inside the pilaster and then press the lower section of the clip while pushing inwards until it snaps into place. Repeat until all clips are in desired location. Place shelf on clips checking that all four corners of shelves are leveled and supported by the four shelf clips.
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 compressor complete three on/off cycles to assure that the temperature inside is appropriate for the products before loading them into the refrigerator. 3. Verify the internal illumination operation by activating the on and off switch. 4.
