Installation
Installation should only be performed by a qualified expert from the sales agency or
elsewhere. Imperfect installation may result in water leakage, electrical leakage,
electric shocks, or fire.
Choose an area with low levels of both heat and moisture.
The cooling performance of the freezer may be adversely affected if it is placed in
direct sunlight or near a source of high temperatures.
If moisture or water comes into contact with the freezer, it may be a cause of poor
electrical isolation or rust.
Allow adequate space around the freezer
Lackofspacemaycausepoorcoolingperformance,breakdownofthefreezer,or
overuse of electricity.

Before commissioning
Warning
Do not put bagged ice packs (including those containing
ammonium nitrate and urea) in the freezer. Leakages from such
bags may cause rust or breakdown of the freezer.
Do not place any form of volatile substance or inflammable, such
as ether, benzene, alcohol, propane gas and glue, etc. inside the
freezer. Failure to follow these instructions may lead to
explosions or fire.
Any type of bottle or can that contains liquid that can be frozen
should never be stored in the freezer since the bottles and cans
may explode. This can lead to personal injury.
Do not touch stored materials, containers (especially metallic ones),
or the inside of the freezer with bare or wet hands. Failure to
follow these instructions may lead to frostbite. Make sure to wear
gloves when working.
1. Install the freezer on a flat and level floor.
Installthefreezeronalevelfloor.
Thefrontsideofthefreezershouldbeapproximately1cmhigherthantheback
side.
2. Clean the inside of the freezer and put the sub-lids.
4. Before storing anything, make sure the inside of the freezer is
fully cooled down.
The plastic odor will disappear once the freezer cools down.
3. Connect the freezer to the exclusive power outlet.
Do not connect the power cord in the middle, or do not use extension cords, or do
not use any electric outlet divider.
Do not turn on the power for 30 minutes after moving, which may cause breakdown.

GB
Before commissioning
(Make sure to read the following)
Warning
If the surrounding temperature is outside
the optimum range (5°C~30°C), it may
cause breakdown.
Please carry out regular checks to ensure
that the circuit breaker is functioning
correctly If it is defective, it may lead to
electric shocks in the case of electrical
leakage.
When a circuit breaker activates, please
consult your sales agency or qualified
experts Forceful power restoration may
cause electric shocks or fire.
Do not place any objects or containers
containing water in the freezer. If they fall
over, they may cause personal injury and
the spilt water may lead to poor electrical
isolation and electric leakage.
Do not hang on the door. The door may
come off the freezer or the freezer may fall
over, leading to personal injury, electric
leakage, or electric shocks.
Do not put your hands in the mechanical
compartment as it contains high speed
fans and heat-generating parts. Failure to
follow these instructions may lead to
personal injury.
Do not climb on the freezer. It may fall over
and cause personal injury.
Do not insert fingers or other objects into
the air vents or air intakes. As the fan
is spinning at a high speed, it may cause
personal injury or breakdown.
If you do not use the freezer for a long time,
for safety purposes, please unplug the
appliance at the outlet. Failure to follow
these instructions may lead to dust collecting
on the power plug resulting in fire.
Do not use the appliance on-board
vehicles or any other type of vessel.
Do not use any inflammable spray, such as
lacquer paint, or any form of volatile
substances or inflammables near the
freezer. Sparks discharged from the
electrical components of the freezer may
ignite such substances that lead to
explosions or fire.
Do not touch the electrical components of
the freezer, such as the power plug and
the switches, with wet hands. Failure to
follow these instructions may lead to
electric shocks.
Do not scratch, convert, bend, pull, or tie
the power cord. Also, do not put any
heavy objects on it. Make sure the cord is
not being pinched. Any damage to the
power cord may cause fire or electric
shocks.
When unplugging the freezer, pull on the
plug itself. Do not pull the power cord. You
may damage the inside wires leading to
overheating and fire.
After switching off the appliance, wait for at
least 10 minutes before switching it on
again. Failure to do so may overload the
compressors, causing a breakdown.
However, please note that the appliance
should be switched on within 1 hour after
the power is cut. If you switch off the
appliance for more than 1 hour, please wait
for at least 48 hours with the door open
before restarting it.
Do not pour or spill water directly onto the
appliance or wash it with water Failure to
follow the instructions may lead to short
circuits or electric shocks.
Use the switch to turn the freezer on and
off inserting or unplugging the plug while
the freezer is switched on may cause
electric shocks or short circuits.
Make sure that the power plug is cleaned
regularly. Always make sure that the plug is
completely inserted into the outlet. A dusty
or dirty plug or incomplete insertion of the
plug may cause electric shocks or fire.

Ensure to restart after min. 10 minutes after stopping the operation.
Restart right away causes the breakdown of a cooler.
1. Insert a power lamp into a socket
2. Turn off AL-1 switch and REMOTE switch.
3. Turn on POWER switch. The display of a temperature adjuster will be on and operation starts.
4. Set the temperature for use within the range of the designated applicable temperature.
5. Store the keeping when the inner temperature of a freezer reaches the set temperature.
For reference, start storing the keeping one by one 7-8 hours after the start operation.
Store the keeping of room temperature little by little.
6. To enable the alarm function, turn on AL-1 switch and REMOTE switch after confirming that
the inner temperature of a freezer is stable..
Follow the order below when star ting the operation.
1. Turn off AL-1 switch and REMOTE switch.
2.Turn off POWER switch. The display of a temperature adjuster will be off and operation will stop.
3. Pull the power plug from the socket.
Follow the or der below when stopping the operation.
A little at a time when storing the keeping of room temperature
This product is for cold reserving (consecutive cooling of what has been cooled already). If a
user puts plenty of the keeping of room temperature into a freezer, the temperature will go up
temporarily and an alarm may go off. When storing the keeping of room temperature in a
freezer, store it a little by a little several times after checking such is cooled enough. Also,
where a user puts plenty of cold storage packs or cold insulati on material into a freezer, the
same state will occur. cold storage packs or cold insulation material has the merit of keeping
the low temperature environment for a long time, but requires considerable amount of time in
cooling, so if a user puts them a lot in a freezer, such will cause a lot of load to the product.
As such, a user shall refrain from storing cold storage packs or cold insulation material. If it's
unavoidable to store them, ensure to put only a little of them.
"Thebatteryforblackoutalarmisconsumable.Thelifeis3yearsafterinstallation.
When the battery is out, an alarm buzzer won't sound even upon blackout, which may
affect the keeping adversely. We recommend that a user should check the battery
regularly and exchange in advance. Inquire of a store a user purchased the product or
the local company about battery exchange.

Alarmfunction
The temperature increase alarm sounds under the following condi tions.
"AL-1switchisON
"Theinnertemperatureofafreezer(PV)is+15°C compared with the set temperature
(SV)
In case of the first use, the alarm will sound because the inn er temperature of a
freezer is high. After confirming sufficient cooling, turn on the AL-1 switch.
This product alarms with a buzzer sounding when the inner temperature of a freezer increases or
power goes out, in order to protect stored items. Furthermore,it has the zero voltage terminal to
output such an alarm signal outside. All is equipped with On/Off switches, so use it as necessary.

Alarm signal output to outside
Where there's an electrical anomaly in the double cooling system (where it doesn't run
because of the breakdown of a freezer), AL-2 lamp (red) turns on. Also, where AL-1
switch is ON, a buzzer sounds interworking with AL-2 lamp.
Where only one cooling system runs as either one has system anomaly, the inner
temperature of a freezer maintains approx. -130°C.
