INSTALLATION LOCATION
This unit must be installed in a location which meets all the conditions described below.
If the unit is installed in a location which does not meet the conditions, its specified performance may not be
achieved or malfunctioning and accidents may occur.
A location not exposed to direct sunlight
Avoid any location which is exposed to direct sunlight. Installing the unit in a location exposed to
direct sunlight may cause its cooling performance to be reduced.
A well-ventilated (airy) location
In order to ensure ventilation, leave clearances of at least 10 cm around the unit (at the left, right and
back). Blocking the ventilation may reduce the unit’s cooling performance or cause malfunctioning.
A location away from sources of heat
Avoid any location which is close to a large source of heat (such as a heater or boiler). Installing the
unit near a large source of heat may reduce the unit’s cooling performance.
A location with minimal changes in temperature
Avoid any location where the ambient temperature is subject to sudden changes. If the unit is
installed in a location where the ambient temperature is subject to sudden changes, it will not be
possible to achieve a stable cooling performance.
A level location where the floor is capable of bearing the total combined weight (product + optional
accessories + storage items)
Install the unit in a location which is not uneven and which is capable of bearing the total combined
weight (product + optional accessories + storage items). If the unit is installed where the surface is
uneven or where the unit will be inclined at an angle, the unit will be unstable, and accidents or injuries
may result and/or vibration or noise may be generated.
A location free of ignitable or corrosive gases
Avoid any location exposed to ignitable or corrosive gases. Ignitable or corrosive gases can cause
explosions and/or a fire. Furthermore, corrosion of the electrical parts may cause the insulation to be
reduced and result in ground faults and/or electric shock.
CAUTION Do not install the unit in any location (such as near a
waste-water facility) where sulfur compounds and other
corrosion-causing substances may be generated.
Corrosion of the copper pipes will cause the cooling unit to
deteriorate, possibly causing the product to malfunction.
A location with minimal humidity
Install the unit in a location where the relative humidity is less than 80 %R.H. Installing the unit in a
very humid location may cause ground faults and/or electric shock.
17
INSTALLATION
When installing the unit, follow the steps below to secure the unit properly, and also be absolutely sure to
connect the unit to ground.
In addition, install a ground fault circuit breaker (on the unit’s power supply side) which is mandatory under the
applicable laws and regulations.
1. Preparations after unpacking
Remove all the tapes used to secure the doors and interior parts, and leave the doors open for a short
while for ventilation.
If any surfaces of the outer cabinet are dirty, wipe off the dirt using a cloth moistened with a diluted
neutral dish-washing detergent.
Using an undiluted solution of a neutral dish-washing detergent may cause the unit’s plastic areas to crack.
Follow the directions of the neutral dish-washing detergent for the dilution details.
After removing the dirt using the diluted neutral dish-washing detergent, be absolutely sure to wipe the surfaces
with a cloth dipped in clean water to remove the traces of the neutral dish-washing detergent. After this, be
absolutely sure to wipe the surfaces with a dry cloth, allow the surfaces of the outer cabinet to dry out, and then
proceed with the installation.
2. Securing and leveling the unit using the leveling feet
Rotate the front leveling feet clockwise until the casters are
raised 5 mm to 10 mm from the surface of the floor. (Fig. 1)
When the casters are raised from the surface of the floor, the
unit is secured. If they are left touching the floor, the unit may
inadvertently move out of position when its doors are opened or
closed.
In addition, rotate the leveling feet slightly clockwise or
counterclockwise, and adjust them so that the unit is level
between the left and right.
3. Securing the unit using the wall-fastening brackets
Use the spacers (which are also used to prevent the
product from toppling over) on the rear panel of the unit,
and secure the unit to a wall with a strong rope or chain
available on the market. (Fig. 2)
The spacers (which are also used to prevent the product from
toppling over) have a dual purpose: To provide a clearance
between the product and the wall behind it, and to prevent the
product from toppling over.
4. Preventing electric shock by connecting the unit to ground
When installing the unit, be absolutely sure to connect it to ground. Grounding is necessary to prevent
the electric shock which will arise when the electrical insulation has deteriorated.
This unit comes with a 3-pole plug with ground pin. Grounding work is not required in the case of a 3-pole power
outlet equipped with a ground contact.
If the power outlet is not a 3-pole power outlet equipped with a ground contact, ask a qualified contractor to do the
grounding work.
WARNING
Be absolutely sure to connect the unit to ground in order to prevent
electric shock. If the unit cannot be connected to ground, ask a qualified
contractor to do the grounding work.
Failure to connect the unit to ground may give rise to electric shock.
Do not connect the grounding wire to a gas pipe, water pipe,
lightning rod or telephone grounding wire in carrying out the
grounding work.
Connecting the unit to ground improperly may give rise to electric shock.

START-UP PROCEDURE
To commence the operation (initially or after temporary power off due to the cleaning, maintenance,
etc.), follow the procedure below:
The operation is resumed automatically at the recovery from power failure with the setting before power failure
[page 20].
1. Check the power switch is OFF.
2. Check that the power switch of battery kit for power failure alarm (option) is OFF if the battery kit for
power failure alarm is installed.
3. Connect the power supply cord to the dedicated power source with the chamber empty.
4. Turn on the power switch.
At the power on, the high temperature alarm is activated. The alarm indicator blinks and the blinking
refrigerator temperature is displayed.
At the start-up with the factory setting, the high temperature alarm is activated when the refrigerator
temperature is higher than 10oC, therefore the high temp. alarm works (High temp. alarm; chamber temp. blinks,
alarm indicator blinks, buzzer sounds after 15 minutes)
5. Set the desired chamber (refrigerator and freezer) temperature [page 21].
The factory setting of refrigerator temperature is 5 oC and the freezer temperature is -30 oC.
<Important> Allow 5 minutes before turn on the power switch when the power switch is off. That
is a time for compressor to start-up again.
<It takes about 2.5 hours to reach the set temperature (ambient temp.; 30 oC, no load, without containers)>
6. On the temp. display, check the chamber temp. reaches the set temperature.
7. Turn on the power switch of battery mounnting box (option) if the battery mounting box is installed.
8. By opening the refrigerator door, check the chamber lamp is on.
9. Put the material in the chamber gradually. [page 19]
Putting a large amount of material in the chamber at a time causes the temperature rise.
Never block the air intake vent or air exhaust vent in the refrigerator.
10. As needed, set the alarm temp. [page 26 to 29], buzzer suspended period [page 30], and the lock of
chamber temperature setting [page 22].

HANDLING OF STORAGE ITEMS
Always follow the indication below when taking out/putting in the material.
Put on the gloves when taking out/putting in the storage items in the freezer chamber. No gloves
may cause injury.
Do not put the excessive storage items in the chamber. Over putting disturbs the cold air
circulation and degrades the cooling performance.
Open/close the doors quickly or the chamber temperature rises.
Do not put a large amount of storage items of high temperature at a time.
Put the storage items close to the shelf center to avoid the contact with the chamber wall. Keep an
adequate space between materials. Contacting with chamber wall or other materials causes
uneven cooling in the chamber.
