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 specicaons. Failure to use an independent
power supply of proper capacity can result in a tripped breaker, blown fuse,
damage to exisng wiring, or component failure. This could lead to heat
generaon or re.
• Unplug the appliance from the electrical outlet prior to maintenance.
• THE APPLIANCE MUST BE GROUNDED: The appliance is equipped with a
NEMA 5-15 three-prong grounding plug to reduce the risk of potenal
shock 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 qualied electrician replace it with a properly
grounded, independent 3-prong wall outlet. Do not remove the ground
prong from the plug and do not use an adapter plug. Failure to follow these

Check for Shipping Damage
Prior to leaving the factory, each appliance is throughly inspected and
performance tested to assure proper operang temperatures.
Check the crate thoroughly for signs of shipping damage. If external
damage exists, internal damage is also probable. Uncrang should be done
while the carrier´s representave is present. Otherwise, the appliance
should be uncrated as soon as possible, preferably within ve (5) days.
The manufacturer is not responsible for in-transit damage and the
consignee must le any required damage claims directly with the carrier.
If the damage is severe and obvious, write a brief descripon of the evidence
on the carrier’s delivery receipt, and above the carrier representave’s
signature. Call the distributor or dealer immediately, indicang that the
appliance was damaged.
If no obvious crate damage is present, within two hours of receiving the
appliance from the carrier, remove the packaging to inspect for concealed
damage.
If concealed damage is found, call the carrier immediately, save all crang
materials, and le the necessary freight claim with the carrier.
• This appliance must be installed in accordance with all applicable
naonal, state, and local regulaons.
• Appliance is heavy. Use care when liing or posioning. Work in pairs

Handling the Appliance
2”
1. Always move the appliance in an upright posion. Do not set the appliance
on its side or upside down as you may damage the appliance and spill the
compressor oil.
2. If liing the appliance, hold it from its base. It is recommended to use a dolly.
3. Do not let the appliance fall abruptly.
1. Place the appliance on a surface solid enough to prevent vibraon and strong
enough to support the combined weight of the appliance and the product
load. Quick guideline: Esmate 35 pounds per cubic foot of storage space.
2. Appliances should never be placed in front of windows or glass doors where
sunlight will be in direct contact with the appliances. If an appliance is located
near a window or glass door, provide an adequate shade to block the sun´s rays.
3. Ambient temperature must be between 45°F (7°C) and 100°F (38°C). Low
ambient temperatures below 45°F (7°C) are as harmful as high ambient
temperatures. Extreme temperatures will denitely aect the performance
of the appliance.
4. Failure to properly level the appliance could hinder proper drainage and door
operaon.
5. Clearance: Leave a space of at least 2” between the back of the appliance and
the wall to provide adequate air circulaon of the unit compartment.
6. The appliance must be placed in the required clear space for safe performance.
Locaon
• This appliance is not intended for outdoor use.
WARNING
14
Remove the Crate and Skid
Level the Appliance
1. Remove the external packaging
(corrugated board and plastic
wrapping). Check for concealed
damage. If any damage is idened,
immediately forward a complaint to
the transportaon company.
2. Move the appliance to its final
locaon, before removing the skid.
3. Using a screwdriver remove the
screws that aaches the skid to the
appliance.

use of the appliance by a person responsible for their safety.
• Children should be properly supervised around the appliance.
• Do not use combusble spray or place volale or ammable substances in or
near the appliance. They might catch re.
• Do not place any product on the oor of the appliance. All product must be
placed on properly installed shelves.
• Do not block air inlets or outlets, otherwise cooling performance may be
reduced.
• Do not ghtly pack the appliance. Allow some space between items to ensure
good air ow. Also allow space between items and interior surfaces.
• Do not put warm or hot foods in the cabinet. Let them cool rst, or they
will raise the appliance temperature and could deteriorate other foods in the
cabinet or overload the appliance.
• Food storage and handling must comply with applicable codes and regulaons.
• Do not climb, stand, or hang on the appliance or doors 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.

Controls and Adjustments
The posion of the appliance temperature control dial is preset to an
appropriate temperature under normal condions.
To change temperature clockwise for colder and counter clockwise for
warmer.
Control module
DEFROST CYCLES
The control module is programmed to perform a defrost cycle:
Every four hours for VUR27A, VUR48A, VWR27A, and VWR48A for a
duraon of 25 minutes.
Every six hours for VUR60A, and VWR60A for a duraon of 25 minutes.
Every eight hours for all the freezers for a duraon of 25 minutes.
These defrosts ensure that the evaporator remains free of ice build-up,
opmizing the performance of the appliance.
The temperature of a refrigerator should be between +31°F (-1°C) to +40°F (4°C)
The temperature of a freezer should be between -12°F (-24°C) to -2°F (-19°C)
