NOTE:
We strongly recommend all preventive maintenance and servicing be performed
by qualified Technicians.
Leak check with Combustible Gas Detector.
Unplug unit before Servicing.
Keep fingers from pinch points during transportation.
Secure lid and the equipment safely during transportation.
If the supply cord is damaged, it must be replaced by a special cord or assembly
available from the manufacturer, or its service agent.

Installation and Operating Instructions:
Note: Use this freezer for its intended purpose as described in this manual.
Before using the equipment, inspect for freight damage. Refuse delivery, if there
is any damage.
Remove the outer packaging, (cardboard and bubble wrap or Styrofoam corners
and clear plastic). Inspect for concealed damage. Again, immediately file a claim
with the freight carrier if there is damage.
Remove the unit carefully from crate. The unit is equipped with 6” or 8” wheels,
two swivel in back and two rigid wheels on front. Only Swivel wheels have a
locking mechanism feature.
Caution - This unit contains R290, a flammable hydro-carbon
refrigerant. While installing, moving, or using the freezer, do not disturb the
refrigerant lines, (bend, puncture, or apply heat).
If you notice anything unusual, find damage, or it is not functioning properly,
remove the unit from service, and call an HVAC technician certified to handle
flammable refrigerants.
A lid, care package and operating manual are located inside the freezer.
BDC-8 and similar freezers are equipped with one or two cold plates. The freezer
must be plugged in for 24 hours on first time use. Based on ambient temperature,
the eutectic solution inside the cold plate will freeze within 16 to 18 hours. For a
re-charge of a cold cart, allow 12 hours.
Freezer may be equipped with a Digital or Manual temperature controller. The
controller is preset for the proper temperature to satisfy the operation based on
the temperature of the cold plates ordered by the customer. No adjustments
should be necessary. NOTE: When the freezer is charging or re-charging, the
temperature must run at negative -30 to -10 degrees F. These cold
temperatures are required to freeze the eutectic solution to a solid state. If
not completely frozen, the plates will not hold the correct temperature for
10 hours after unplugging.
The controller is located behind the louver grill. For adjustment, remove the
louver. A flat head screw driver is needed to adjust the manual controllers.
A Wiring Diagram is located inside the condensing unit area. Remove the louver
grill to access the diagram.

Before your new unit is connected to a power supply, check the incoming voltage
with a voltmeter. If anything, less than 100% of the rated voltage for operation is
noted, correct it immediately.
RECOMMENDATION:
Before loading product into your NELSON freezer we recommend you run your
unit empty for two days. This is a pre-startup check to ensure the unit is working
properly. Remember, our factory warranty does not cover product loss!
HOW IT WORKS:
Eutectic is a fancy word that refers to a substance that has the same consistent
chemistry as the material goes through the transition of water to ice to water repeatedly.
The eutectic solutions in our cold packs are basically salt water with some other traces
of alcohols and some “magic dust”. These solutions, while not pleasant to drink, are
non-toxic. True eutectics (as opposed to glycols or organic materials like the “blue ice”
stuff you can buy for keeping your lunch chilled) are the most efficient method to store
“cold” energy. You get the most stored energy per pound of material.
When water freezes, it stores tremendous energy. As it melts, it releases that stored
energy very efficiently. For instance, the amount of energy to make a pound of water
drop from 34 degrees to 33 degrees is 1 unit of energy (BTU if you want the technical
stuff). The energy required, however, to go from 33 degree water to 32 degree ice is
144 units of energy. We call the transition from liquid to ice and ice to liquid a phase
change in the material. The energy to keep products cold for extended periods relies on
the energy stored during the phase change of the solution. The requirement to have the
solution go through the phase change leads to a very important point. Cold plates will
only work for any length of time when they are completely frozen. Putting product in a
cold plate cart will do very little holding if the cold plates are not frozen solid.
OPERATION & CARE OF THE CABINET:
Caution - This unit contains R290, a flammable hydro-carbon refrigerant. If the unit is
not functioning properly, remove it from service, and call an HVAC technician certified to
handle flammable refrigerants.
Do not operate the freezer unless the louver grills are properly secured in place.
Simply plug the cart into an outlet following the guidelines above. The compressor will
run for approximately 24 hours, or until the cart shuts off on its own when it reaches the
thermometer set point. It is then frozen, essentially storing energy in the walls, for a 10
hour day of use. After any length of use, simply plug back in for a 12 hour recharge.

There is no harm in leaving the cart plugged in at all times when not in use. If the lid is
left on, the compressor may not start up for days. The sensor will detect when it needs
to run & recharge.
Packaged popsicles and ice creams may remain in the cart when not in use as long as
cart is plugged in. Products that are scooped will need to be stored in a different cabinet
while the cart is charging.
In a standard household outlet, there are two receptacles. There should not be any
other major appliance sharing the same outlet. The second receptacle should not be
used
Do not plug in a cart when the temperature of the location is below 40 degrees F.
Your new C. Nelson mfg. low temperature cabinet represents the finest in engineering
design, quality of material and craftsmanship effort. It will give you many years of
trouble free service with a minimum of attention.
The easy-to-clean exterior surfaces should be wiped off regularly with a luke warm, mild
detergent solution. Do not use any solvent-type cleaners which could attack the plastic
and vinyl parts of the cabinet. Never clean the lids or cabinet with steam or extremely
hot water. DO NOT WASH LIDS IN A DISHWASHER.
From a sanitation standpoint, it is important that the interior of the cabinet also be
cleaned periodically. Most of our models are manual defrosting where a shutdown will
permit complete frost removal with a resultant increase in operating efficiency. To clean
the interior of the cabinet remove the lids and the product and unplug the unit, or turn
the temperature control to the off position. When the cabinet has warmed up, any
remaining frost accumulation may be scraped off the walls with a plastic or wood
scraper. Never use a sharp or pointed metal scraper since it could damage the finish or
possibly pierce the walls. The same type of lukewarm detergent solution used for the
exterior can be used on the interior. Wipe the interior of the cabinet dry, replace the lids
and plug in the cart. Wait several hours before reloading the cabinet with product.
No oiling of the equipment is required.
A lock bar is included with every cart and secured to the handle bar with a lanyard. It
can be stored in the umbrella when not in use. Not only is a lock bar included for
security reasons, you need to use it in transit. The lid will fly off if not secured with the
bar and a padlock at the end. (Padlock not included.) Install lock bar, open channel up,
by slipping the hooked end into the one tab, lay flat perpendicular to the lid hinge. Lay it
down flat and slip through the second tab and add a lock.

Since each and every self-contained C. Nelson Mfg. Co. cabinet is chart tested on its
own temperature recording clock before shipment, service attention is reduced to a
minimum. Further, each cabinet carries a part guarantee of one year (unless otherwise
provided for) as outlined in the standard C. Nelson Mfg. Co. warranty. NOTE: Should
parts be required, it is important that correct model and cabinet serial number is given.
