DIRECTIONS FOR STORAGE AND HANDLING OF THE E Q UIPMENT

STORAGE OF 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.

UNCRATING

The following procedure is recommended for uncrating the unit:
Remove the outer package by carefully cutting the banding and removing the cardboard box.
Inspect for concealed damage. Immediately file a claim with the freight carrier if there is damage.

•••• www.ojedausa.com • [e-mail] • Pg. 3 ••••

Move your unit as close to the final location as possible before removing the wooden skid.

MOVING THE EQUIPMENT

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 movi ng vehicle, secure the freezer in an upright position and cover it to protect
the outside of the cabinet.

PLACING AND INSTALLING THE EQUIPME NT

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.

ENERGY SAVINGS IDEAS

The location of the cooler must be kept away from sources of heat and humidity including direct
sunlight, 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.

•••• www.ojedausa.com • [e-mail] • Pg. 4 ••••

ELECTRICAL REQUIREMENTS

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 electri c 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 electrical output. If voltage varies by 10
percent or more, f reezer performance ma y be affected. Operatin g 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 ACCO RDING T O THE NAMEPLATE AMPS.

PRODUCT LOADING

The CHP 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.

BASKET SPECIFICATIONS

The baskets have been designed to withstand the rigors of normal use. Avoid product overloading to
prevent deforming the baskets.

UNIT OPERATION

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.

POWER FAILURE/FREEZER FAILURE

Note: Do not open the freezer door unnecessarily if power to the freezer is off for several hours

If a power failure occu rs, frozen foods will sta y 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 Servi ce Checklist Secti on of
