you may want to consider a direct connection to the 
electrical source.  No less than a No. 14 gauge wire should 
be used for the electrical connection. 

 Follow your 

country’s electric codes.  

 

The electrical outlet should not be controlled by a wall 
switch, which might be turned off accidentally. 

This cabinet is equipped with a three-prong (grounding) plug 
for your protection against shock hazards.  The cabinet 
should be plugged directly into a properly grounded three-
prong receptacle.  

Where a two-prong wall receptacle is encountered, it must be 
replaced in accordance with the National Electronic Code 
and local codes and ordinances. A licensed electrician must 
do the work. 

 

*WARNING: Do NOT under any circumstances cut or 
remove the round grounding prong from the cabinet 
plug. 

 

*CAUTION

: Incorrect voltage can result in severe 

damage to the equipment. 
 
 
 

*CAUTION

: For personal safety and trouble-free 

operation, this cabinet must be properly grounded before it is 
used.  Failure to ground

 

the

 

equipment may cause personal 

injury or damage to the equipment.  Always conform to the 
National Electrical Code and local codes.  Do not plug in the 
cabinet to overloaded power lines. 
 
**Your freezer must be electrically grounded to prevent 
electric shock. 

 

 

Consult a licensed electrician if you have ANY doubt 
about the grounding of your wall receptacle.  Only a 
licensed electrician can determine the polarization of 
your wall receptacle. 

 
 
6 USING YOUR LOW TEMPERATURE FREEZER 

 
Any temperature below 0

°

 Centigrade or 32

°

 Fahrenheit 

provides a potential condition to cause freezing of water or 
material containing water.  Material containing water 
solutions of salt or sugar will freeze at a slightly lower 
temperature, depending on the content of the solution. 
 
Because all warm-blooded creatures are composed of a great 
percent of water with salinity, they are subject to freezing 
whenever the body cells, parts or extremities reach 
temperatures below freezing.  Therefore, it behooves the use 
of caution whenever you use a freezer or handle a frozen 

product that is at temperatures below 0

°

 Centigrade or 32

°

 

Fahrenheit. 
 

 

6.1 When Skin Freezes 

When your skin is exposed to subfreezing temperatures for 
an extended amount of time, it can freeze.   Your blood 
vessels constrict in response to dropping temperatures.  This 
reduces the flow of blood and, therefore, the amount of 
oxygen to the tissues.  When water in these tissues freezes 
and forms ice crystals, cell structure is destroyed.  
 
Tissue damage from cell death interrupts circulation in the 
smallest blood vessels.  Blood clots form and blood flow is 
further diverted away from the frozen tissue.  At this point, 
your skin temperature drops and the injured area grow even 
colder.  
 
The first sign of frostbite may be a slightly painful tingling 
sensation, which often is followed by numbness.  Your skin 
may look pale, and feel hard, cold and numb. 
 
In the event of frostbite, warming is vital.  Carefully warm  
frostbitten areas gradually.  Place your hands directly on the 
skin of warmer areas of your body.  If possible, immerse 
your hands in water that is slightly above normal body 
temperature (about 100

°

F or 37.8

°

C), or which feels warm to 

someone else, until your normal color returns.  Do not use 
direct heat.  Seek medical attention as quickly as you can. 
 

 
 
6.2 After Thawing  

 
Frostbitten areas will turn red and throb, or burn with pain, 
as they thaw.  Even with mild frostbite, normal sensation 
may not return immediately.  When frostbite is severe, the 
area will probably remain numb until it heals completely. 
 
Severe frostbite damages nerves and can permanently change 
your sense of touch in the affected area.  

 

 

 

 

 

 

  

 

 

 

 

 

*CAUTION: Wear protective clothing while either 
handling or coming in contact with inside of freezer.  
Hands should be dry and protected by using gloves.  
Insulated gloves are best for extended use when 
handling frozen product.  Sleeves or arm-length 
insulated gloves should protect arms.  Coats, 
insulated aprons, etc should protect other parts of the 
body that may be exposed to the cold.  

Frozen packages are hard and often slippery, 
therefore foot protection should be considered such as 
hard-toed shoes or foot guards in the event that a 
package would be dropped.
