CAUTION
zConnect the unit to a power source as printed on the data plate located
on the lower right side of the unit. Use of any other voltage or frequency
other than that on the rating label may caus damage to the unit, fire or
electric shock.
zWhen removing the plug from the power supply outlet, grip the power
supply plug, not the cord. Pulling the cord may result in electric shock or
short circuit.
zDo not damage or break the power supply plug or cord. Do not use the
power supply plug if its cord is loose. This may cause fire or electric shock.
zDo not touch any electrical parts such as the power supply plug or any
switches with a wet hand. This may cause electric shock.
zPut on dry gloves when you remove frozen items from the freezer.
Handing frozen contents or the inside walls with naked hand may cause
frostbite.
zDo not defrost the inside walls with a knife or any sharp object. There
are cooling pipes behind the walls. Be careful not to damage these pipes.
Do not make holes in the cabinet walls to install attachments.
zChecks the filter mentioned in this manual and clean it when necessary. A
dirty filter may cause temperature fluctuations, or total product failure.
zDisconnect the power supply plug before moving the unit. Take care not
to damage the cord. A damaged cord may cause electric shock or fire.
zDo net tilt the unit while moving it.
zDisconnect the power plug when the unit is not used for a long time.

2. Usage Precautions
1. Do not defrost the inside walls with a knife or any sharp object.. The
cooling pipes run behind the cabinet walls. Be careful not to damage
the pipes because this could cause breakdown. Do not make holes in
the cabinet walls to installation attachments.
2. Frost will accumulate on the inside walls of the freezer during normal
use. Excess frost may make the internal doors difficult to open..
Remove the frost with a spatula, or a similar tool. Frost can be wiped
off with a clean, dry cloth.
3. An access port for the measuring cable in the case is provided on the
back wall of the freezer. Be sure to replace the cap and heat insulator
after removing the cable or the inside temperature may not be reached
and frost may accumulate outside the port.
4. In case of high ambient temperatures, the cabinet front may heat up
after the freezer starts to operate for the first time. This is normal and
does not suggest a malfunction. It is caused by hot gas piped around
the unit to prevent frost or ice from adhering to the cabinet.

3. General Recommendations
The refrigeration system is designed to maintain ultra-low temperatures with safety in
a +32oC ambient environments, only when the freezer is used for its intended purpose
( storage).
CAUTION!
This unit is not a “rapid-freeze” device. Freezing large quantities or liquid, or
high-water content items will temporarily increase the chamber temperature
and will cause the compressors to operate for a prolonged period of time.
Improper use of the freezer may jeopardize safety or cause undue stress or
damage to the compressors.
Avoid opening the door for extended time periods because cold chamber air will
rapidly escape. Room air, which is higher in humidity, replacing chamber air may
cause rapid frost build-up in the chamber.
3.1 Environmental Conditions
This equipment is designed to operate in following conditions:
1. Indoor use;
2. Ambient temperature between 15°C and 32oC;
3. Main supply voltage fluctuation not to exceed +10% to -10% of normal
voltage.
Initial Loading
When loading the unit with “pre-frozen” materials, the operating temperature set point
should not be set lower than the temperature of the “pre-frozen” material. Allow the
unit to operate at the set point for eight hours. The set point may than be lowered in
increments no greater than 10oC.Allow a stabilizing period of eight hours for every
ten degrees, until the desired set point is achieved.
CAUTION!
Failure to follow these procedures, or overloading the unit, may cause
excessive stress on the compressors any jeopardize user safety.

4. Pre-Installation
On delivery, unpack the unit and check the cabinet exterior for signs of damage.
CAUTION!
Do not discard the internal lids from chest-style units. These lids are
necessary to maintain the correct temperature, moisture control, and general
operational efficiency.
5. Installation
Do not deviate from the electric and temperature ratings printed on the data plate
located on the rear, lower right side of the unit.
CAUTION!
Incorrect operation of the equipment could result in potentially dangerous
conditions. To avoid hazards and minimize risk, follow all instructions and
operate the unit within the limits stated on the data plate.
5.1 Positioning
Install the unit on a vibration free, level floor, with a minimum of fifteen centimeters
of space on the sides, rear, and top. Refer to Section 5.3 for instructions on leveling
cabinets. Allow enough clearance so that door or lid can open at least 90 degrees.
Do not position the equipment in direct sunlight or near sources of heat such as
diffusers, radiators etc. The ambient temperature range at the site must be 15°C to
32oC.
WARNING!
Install the unit on a sturdy floor.
WARNING!
Never install the unit in a flammable or volatile location. This may
result in fire or explosion.
Never install the unit where acid or corrosive gases are present.
Current leakage or electric shock may result due to corrosion.

WARNING!
Do not use outdoors. Current leakage or electric shock may result if
the unit is exposed to water.
Never install the unit in an excessively humid environment. or where
there is a high risk of being splashed. by water. Deterioration of the
insulation may result which could cause current leakage or electric
shock.
CAUTION!
To allow for proper air flow, a minimum of fifteen centimeters clearance is
required behind the freezer.
5.2 Wiring
CAUTION!
Connect the equipment to the correct power source. Incorrect voltage can
result in damage to the equipment.
CAUTION!
For personal safety and trouble-free operation, the unit must be properly
grounded. Failure to ground the equipment may cause personal injury or
damage to the equipment. If the power supply outlet is not grounded, it is
necessary to install a ground from the ground screw located on the lower
right rear side of the unit by qualified engineers.
If possible, it is preferable to connect the freezer to a dedicated (separate) power
supply.. Each freezer is equipped with a service cord and plug designed to connect it
to a power outlet which it delivers the correct voltage. Supply voltage must within
+10% to -10% of the freezer’s rated voltage.
CAUTION!
Never cut or remove the grounding prong from the service cord plug. If the
prong is removed, the freezer will not be properly grounded.
