WARNING

Failure to observe WARNING signs could result in a hazard to personnel possibly resulting in serious injury or death.

As with any equipment that uses CO2 gas, there is a likelihood of oxygen depletion in the vicinity of the equipment. It is important that you assess the work site to ensure there is suitable and sufficient ventilation. If restricted ventilation is suspected, then other methods of ensuring a safe environment must be considered. These may include atmosphere monitoring and warning devices.

Do not touch any electrical parts such as the power supply plug or any switches with a wet hand. This may cause electric shock.

Only qualified and authorised engineers shall install the unit.

Be sure to install the unit on a sturdy floor. If the floor is not strong enough or the installation site is not adequate, this may result in injury from the unit falling or tipping over.

Carefully with the power cord to avoid short circuit or open circuit. When 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 fire by short circuit. Don't make the power line pack and pressed by furnish or heavy goods. Also please don't close to the compressor and heat source.

Please insert the power plug firmly to avoid leakage.

Rev. 01

User and maintenance manual

Use a power supply outlet with ground (earth) to prevent electric shock. If the power supply outlet is not grounded, it will be necessary to install a ground by qualified engineers.

Make sure a dedicated power source is used as indicated on the rating label attached to the unit. Out of the rate, should install a property transformer and a proper voltage stabilizer for safe operation.

Be sure to install the unit on a sturdy floor, no shaking and tilting.

Never install the unit in a flammable or volatile location. This may cause explosion or fire.

Never install the unit in a humid place or outdoor or a place where it is likely to be basked straightly. Deterioration of the insulation may result which could cause current leakage or electric shock.

Do not place the device lateral tilt, do not impact the device; the device is equipped with refrigeration systems, roll or shock will easily damage the device.

Be sure to install the device in a dry dust-free environment to avoid overheating, short circuit and other dangers.

If there is an unexpected sound, smell, smoke when the power is turned on, unplug the power and contact the manufacturer or supplier. Continued abnormal operation may cause electric shock or fire.

Make sure to put the device in a dry and ventilated location, to ensure that equipment vents and wall surface of the instrument or other items have not been blocked; Do not use the device in a poorly ventilated environment, or the equipment may be damaged by the release of heat.

Never disassemble, repair, or modify the unit by yourself. Any such work carried out by an unauthorized person may result in fire or injury due to a

malfunction. Smeg will be no responsible for such work.

Use this unit in safe area when treating the poison, harmful or radiate articles. Improper use may cause bad effect on your health or environment.

Never place the unit through on a gas pipe, water main, telephone line or lightning rod. Such grounding may cause electric shock in the case of an incomplete circuit.

Use a power supply outlet with ground (earth) to prevent electric shock. If the power supply outlet is not grounded, it will be necessary to install a ground by qualified engineers.

CAUTION

Failure to observe WARNING signs could result in injury to personnel and damage to the unit and associated property.

Ultra-low temperature device is not available to store liv ing things or other critical articles which is not suitable for low temperature storage.

The temperature inside the device is very low during the normal working. Do not touch the interior surface of the chamber or the object inside without wearing protective gear.

Always disconnect the power plug when the unit is not used for long periods.

Make sure to prepare a safety check sheet when you request any repair or maintenance for the safety of service personnel. Be sure to check set point of the controller before restarting the device.

Always hold the handle when closing the door. This will reduce the likelihood of a trapped finger.

Keep the key properly avoiding the children take it to open the door which may result in unexpected injury.

Select a level and sturdy floor for installation. This precaution will prevent the unit from tipping. Improper installation may result in water spillage or injury from the unit tipping over.

Check the filter mentioned in this manual and clean it properly and periodically.

Rev. 01

User and maintenance manual

A dusty filter may cause temperature rise or failure.

Do not tilt the unit more than 45 degrees when moving the unit. All transportation shall be done carefully.

1.3 Precautions for use

• When the device is running, the front part of the device may get hot. This is not a malfunction: In order to prevent dew condensation around the case body, a heated anticondensation tube is installed in the cryogenic storage case.

• Before putting the items in the device, please make sure the temperature inside the chamber has reached the set temperature, and then put the items in batches. Add no more than 1/3 of the container volume each time, in case the temperature rises too much.

• The temperature display value shows the temperature of temperature sensors inside the device. Although the displayed temperature may sometimes differ from the actual temperature in the center of the device, it will get close to the real temperature gradually.

• A through-hole is installed on the side or back of the device to allow test lines to exit the test box. After drawing out the test lines, be sure to re-plug the test hole with insulating material, otherwise the temperature inside the box will not be completely lowered, resulting in condensation around the outside of the hole.

• Clean the device with diluted neutral detergent. Do not use brushes, acid, gasoline, soap, polish or hot water to clean the frozen storage container, as these materials may damage the surfaces and plastic and rubber components.

• After a period of operation, mostly if the frequency of door openings is high, a layer of frost may form on the inner wall and the inner door. If the frost layer is too thick, it will affect the insulation effect of the device and increase the power consumption. Therefore, after a period of time, when the frost layer reaches about 5mm, it should be defrosted with the defrost shovel included.

• Please remove the frozen items in the device and put them in a suitable storage place before defrost, so as to avoid the damage of goods for temperature rise.

• There are many cooling coils on the back and side of the inner wall. Don't use sharp objects such as knives, ice chisel, or screwdrivers to remove the frost on the inner wall. Be careful not to scratch the inner wall when defrosting, otherwise it will cause a failure of the device.

• Cut off the power when the refrigerated storage box will not be used for a long time.
