Important Safety Information

Throughout this manual, notices appear to bring your attention to situations which could result in death, serious injury, damage to the appliance, or damage to property.

WARNING Indicates a hazardous situation which could result in death or

serious injury.

NOTICE Indicates a situation which could result in damage to the

appliance or property.

IMPORTANT Indicates important information about the use and care of the

appliance.

WARNING

The appliance should be destined only to the use for which it has been expressly conceived. Any other use should be considered improper and therefore dangerous. The manufacturer cannot be held responsible for injury or damage resulting from improper, incorrect, and unreasonable use. Failure to install, operate, and maintain the appliance in accordance with this manual will adversely affect safety, performance, component life, and warranty coverage.

To reduce the risk of death, electric shock, serious injury, or re, follow basic precautions including the following:

• Only qualied service technicians should install and service the appliance.

• The appliance must be installed in accordance with applicable national, state, and local codes and regulations.

• Appliance is heavy. Use care when lifting or positioning. Work in pairs when needed to prevent injury or damage. Do not lift using the refrigeration area, the top section, or the doors/drawers.

• To reduce the risk of electric shock, do not touch the plug with damp hands.

• Unplug the appliance before servicing.

• The appliance requires an independent power supply of proper capacity. See the nameplate for electrical specications. Failure to use an independent power supply of proper capacity can result in a tripped breaker, blown fuse, damage to existing wiring, or component failure. This could lead to heat generation or re.

• THE APPLIANCE MUST BE GROUNDED. The appliance is equipped with a NEMA5-15 three-prong grounding plug hazards. It must be plugged into a properly grounded, independent 3-prong wall outlet. If the outlet is a 2-prong outlet, it is your personal responsibility to have a qualied electrician replace it with a properly grounded, independent 3-prong wall outlet. Do not remove the ground prong from the power cord and do not use an adapter plug. Failure to follow these instructions may result in death, electric shock, or re.

to reduce the risk of potential shock

• Do not use an extension cord.

WARNING, continued

• Do not use an appliance with a damaged power cord. The power cord should not be altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could result in electric shock or re. To unplug the appliance, be sure to pull the plug, not the cord, and do not jerk the cord.

• The GREEN ground wire in the factory-installed power cord is connected to the appliance. If it becomes necessary to remove or replace the power cord, be sure to connect the power cord's ground wire.

• Do not splash, pour, or spray water directly onto or into the appliance. This might cause short circuit, electric shock, corrosion, or failure.

• Do not make any alterations to the appliance. Alterations could result in electric shock, injury, re, or damage to the appliance.

• The appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

• Children should be properly supervised around the appliance.

• Do not climb, stand, or hang on the appliance or doors/drawers or allow children or animals to do so. Do not climb into the appliance or allow children or animals to do so. Death or serious injury could occur or the appliance could be damaged.

• Be careful not to pinch ngers when opening and closing the doors/drawers or rail cover. Be careful when opening and closing the doors/drawers or rail cover when children are in the area.

• Open and close the doors/drawers and rail cover with care. Opening the doors/drawers or rail cover too quickly or forcefully may cause injury or damage to the appliance or surrounding equipment.

• Do not use combustible spray or place volatile or ammable substances in or near the appliance. They might catch re.

• Keep the area around the appliance clean. Dirt, dust, or insects in the appliance could cause harm to individuals or damage to the equipment.

• Do not throw anything onto the shelves or load any single shelf with more than 120lb. (54.5 kg) of product. They might fall off and cause injury.

• Do not load any single drawer with more than 150 lb. (68 kg) of product. Depending on the weight of product in the drawers, secure the unit as necessary to prevent it from overturning. Do not open more than one drawer at a time.

• The appliance is designed only for temporary storage of food. Employ sanitary methods. Use for any other purposes (for example, storage of chemicals or medical supplies such as vaccine and serum) could cause deterioration of stored items.

• Do not block air inlets or outlets, otherwise cooling performance may be reduced.

• Do not tightly pack the cabinet. Allow some space between items to ensure good air ow. Also allow space between items and interior surfaces.

WARNING, continued

• Do not put warm or hot foods in the cabinet. Let them cool rst, or they will raise the cabinet temperature and could deteriorate other foods in the cabinet or overload the appliance.

• All foods in the cabinet should be wrapped in plastic lm or stored in sealed containers. Otherwise foods may dry up, pass their smells onto other foods, cause frost to develop, result in poor appliance performance, or increase the likelihood of cross-contamination. Certain dressings and food ingredients, if not stored in sealed containers, may accelerate corrosion of the evaporator, resulting in failure.

• Do not store items near air outlets in the cabinet. Otherwise, items may freeze up and crack or break causing a risk of injury or contamination of other food.

• The entire rail must always be covered by rail dividers and pans. Otherwise, the appliance will not cool properly. Use only pans up to 6"(15cm) deep. Do not use

damaged rail dividers or pans.

• Ingredients must be pre-chilled to 37°F (3°C) or less before placing in rail.

• Keep the rail cover closed when not actively preparing food.

• The rail is for keeping ingredients cool while preparing food. If not actively preparing food for a long period such as overnight, seal pans with plastic wrap in addition to closing the rail cover. Depending on conditions, the cabinet temperature setting may need to be adjusted to prevent items from freezing. Alternatively, seal ingredients and store them in a refrigerator or freezer.

• For CPT46(-D) models, the anti-tip bracket must be properly installed and adjusted. Otherwise, the unit may tip, resulting in injury or damage.

NOTICE

• Protect the oor when moving the appliance to prevent damage to the oor.

• Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear of obstruction. The factory-installed rear bumpers must be in place to ensure proper rear clearance. Blockage of airow could negatively affect performance and damage the appliance.

• Do not allow the appliance to bear any outside weight.

• To prevent deformation or cracks, do not spray insecticide onto the plastic parts or let them come into contact with oil.

• To avoid damage to the gasket, use only the door/drawer handle when opening and closing.

• Do not leave the doors/drawers open.

• To avoid damage to the top seal, do not lift the appliance by the top section or remove the top section.

• Do not place anything on top of the rail cover and do not lift the appliance by the rail cover. The rail cover is not designed to bear any outside weight.

• Do not place anything on the air duct panels beneath the pans in the rail. The air duct panels are not load-bearing.
