WARNING CHILD SAFETY!
Destroy carton, plastic bags, and any exterior wrapping material immediately after the freezer is
unpacked. Children should never use these items for play. Cartons covered with rugs, bedspreads, plastic
sheets or stretch wrap may become airtight chambers and can quickly cause suffocation.
A child might suffocate if he crawls into a freezer to hide or play. Remove the door of a freezer
when not in use, even if you plan to discard the freezer. Many communities have laws requiring you
to take this safety precaution.
Remove and discard any spacers used to secure the shelves during shipping. Small objects are a choke
hazard to children.
ADDITIONAL WARNING
-Please use care when moving or handling this equipment. It is equipped with ammable
refrigerant and damage to refrigerant tubing will increase the risk of a leak.

PLACING AND INSTALLING EQUIPMENT
ENVIRONMENTAL CONDITIONS
THIS UNIT CANNOT BE INSTALLED IN ENVIRONMENTS WITH EXPLOSIVE GASES. THE
EQUIPMENT IS DESIGNED ONLY FOR INDOOR OPERATION.
The unit must be located in an indoor environment.
For the correct performance of the refrigerating system, it is very important to leave at least 10 cm
(4”) of free space both at the sides and back to allow proper air circulation. Do not block the grills on
the side or back of the cabinet.
STORAGE OF THE EQUIPMENT
UNCRATING
MOVING THE EQUIPMENT
If the equipment will be kept in storage, it is suggested to keep it in its original packing. In case you
need your equipment to be inactive for a long period of time after being used, verify that it has been
unplugged. After cleaning it thoroughly with a damp cloth, lukewarm water and neutral soap and
carefully drying it, cover it with a polyethylene film or similar waterproof material.
The following procedure is recommended for uncrating the unit:
Remove the outer package by carefully cutting the shrink wrap and removing the 4 corner posts
and top lid. Inspect for concealed damage. Immediately file a claim with the freight carrier if there is
damage. Move your unit as close to the final location as possible before removing the wooden skid.
The unit is shipped with casters to facilitate moving the unit into position.
Disconnect the power cord plug from the wall outlet. Remove product, then defrost, and clean the
freezer. Secure all loose items such as baskets and fix the lids by taping them securely in place to
prevent damage. In the moving vehicle, secure the freezer in an upright position and cover it to protect
the outside of the cabinet.

www.ojedausa.com |5
The location of the cooler must be kept away from sources of heat and humidity including direct sun-
light, toasters, ovens, coffee warmers, other appliances condenser air discharge, infrared heaters, or
other heat generating appliances.
Overloading the freezer forces the compressor to run longer. Do not exceed the load limit according
to labels fixed on the inner cabinet (which corresponds to the baskets height).
Product to be loaded should be at -4° F (-20° C) since the equipment is intended for maintaining a
cool product at 0° F (-18° C) at load level rather than freezing a warm product
Keep the lids closed to avoid warm air and moisture getting into the freezer.
The NBH series of units are not intended to be a pull down freezer and as such the product must be
loaded at their intended merchandising temperature.
Before loading products, allow the equipment to operate empty for at least four hours.
ENERGY SAVING IDEAS
PRODUCT LOADING
The power cord of this appliance is equipped with a 3-prong (grounding) plug which mates with a
standard 3-prong (grounding) wall outlet to minimize the possibility of electric shock hazard from this
appliance. The use of extension cords is not permitted and will void the warranty.
Before connecting your equipment, check that the electrical data on the data plate match your elec-
trical output. If voltage varies by 10 percent or more, freezer performance may be affected. Operating
the freezer with insufficient power can damage the compressor. Such damage is not covered under
the warranty. If you suspect voltage is high or low, consult your power company for testing.
To prevent the freezer from being turned off accidentally, do not plug unit into an outlet controlled by
a wall switch or pull cord.
Do not pinch, knot, or bend the power cord in any manner.
IMPORTANT NOTICE: PLUG THE EQUIPMENT INDEPENDENTLY TO A LOAD CENTER WITH AN
APPROPRIATE CIRCUIT BREAKER ACCORDING TO THE NAMEPLATE AMPS.

BASKET SPECIFICATIONS
UNIT OPERATION
POWER/FREEZER FAILURE
www.ojedausa.com |6
The baskets have been designed to withstand the rigors of normal use. Avoid product overloading to
prevent deforming the baskets.
SETTING THE TEMPERATURE CONTROL
To access the temperature control, the right side grill should be removed using a Phillips screw
driver.
The temperature control is factory pre-set to provide satisfactory product storage products.
However, the temperature control is adjustable to provide a range of temperatures for your personal
satisfaction. If a colder temperature is desired, turn the control clockwise. Allow several hours for
temperature to stabilize between adjustments.
Note: Do not open the freezer door unnecessarily if power to the freezer is off for several hours
If a power failure occurs, frozen foods will stay frozen for at least 2 hours if the freezer is kept closed.
If the power failure continues, pack seven or eight pounds of dry ice into the freezer every 24 hours.
Cover the product with a cardboard sheet or one inch polyurethane sheet and close the lids. Always
wear gloves and use caution when handling dry ice.
If the freezer has stopped operating, see “Freezer does not run” in the Service Checklist Section of
this manual. If you cannot solve the problem, call an authorized service immediately. Do not allow
inexperience people to repair or modify the electrical wiring and/or refrigeration components.
