◦ Note: The angle of inclination of the storage box must not be greater than 45° during handling.

5. Precautions of using

◦ After the storage box is installed or moved for the first time, let it stand for 24 hours after the storage box is in place, and let the compressor oil return fully before starting up.

◦ This product is equipped with phase sequence and phase loss protector. If the "power error" alarm occurs when the first power is switched on, please try to check the power condition first and then change the installation position of any two fire wires.

◦ Each casters at the bottom of the product has a positioning cushion. In order to prevent the box from moving at will, after the product is in place, adjust the supporting cushion screw disk to make the supporting cushion and the floor support.

◦ When the storage box is running, the surrounding of the storage box frame may become hot. This is not a malfunction. In order to prevent condensation around the box frame, a dew-proof tube was installed around the cabinet.

◦ Before putting the items into the storage box, make sure that the temperature inside the box has dropped sufficiently, and then put the items in batches to prevent the temperature from increasing.

◦ The temperature display value of the cryogenic storage box is the temperature at which the temperature sensing probe in the storage room is displayed. Although the displayed temperature sometimes differs from the actual temperature in the central part of the storage tank, it will gradually approach the actual temperature.

◦ Use a diluted, neutral detergent to clean the equipment (undiluted detergent will damage the plastic components. Refer to the detergent manual for the dilution method). Brushes, acids, gasoline, soap powder, polishing powder, or hot water should not be used to clean the storage tank because the above materials may damage the painted surface and plastic rubber parts. Be careful not to wipe the plastic rubber parts with volatile solvents such as gasoline.

◦ When the battery is tested for the first time or when it is not used for a long period of time, there may be a situation where the battery is discharged because its rechargeable battery has been completely discharged. This does not mean that a failure has occurred. In this case, to maintain sufficient battery capacity, it is necessary to keep the storage box running for about 7 days.

◦ After the storage tank is operated for a period of time, a layer of frost will form on the tank liner. If the frost layer is too thick, it will affect the cooling effect of the storage box and increase the power consumption. Therefore, when the frost layer reaches about 5mm at intervals, it should be defrosted.

◦ Before defrosting, please take the frozen items in the box and store it in another freezer to prevent the temperature inside the box from rising and damage the items.

◦ When the storage box is not used for a long time, the power should be turned off. Turn off the power switch and turn off the battery switch (if there is a corresponding switch).

◦ The speed should not be too fast every time the door is opened and closed, which may result in the difficulty of opening the door and the tightness of the door.

◦ The frequency of opening the door in use should not be frequent. It is better to open the door more than half an hour. Do not open the door more than 1 minute each time. Before closing the door, wipe the ice water on the door seal to ensure a good sealing effect. Failure to do so may cause the temperature in the storage tank to remain below the set temperature, and at the same time reduce the frost on the evaporator and the inner wall of the tank.

◦ When an electrical fault such as a leakage or a short circuit occurs during use, immediately disconnect the power supply.

◦ After installing or moving the storage box for the first time, after it is in place, it needs to stand for 6 hours and then be powered on.

◦ When there are many items, please store them in batches. Each batch must not exceed one third of the volume of the cabinet. After placing the first batch of articles, wait for the temperature to stabilize before putting in the second batch to ensure that the temperature inside the box is stable.

◦ During the use of the storage box, if the door is opened for too long, the external hot air will enter the box, causing a high temperature alarm. This is a normal phenomenon. Please pay attention to reducing the time and frequency of door opening and closing as much as possible.

◦ In order to prolong the life of the storage box and reduce energy consumption, it is recommended that the temperature of the storage box is set between -40°C and -150°C.

◦ If the freezer does not cool after 2 to 3 hours of power-on, unplug it and contact the customer as soon as possible.

◦ Clean the condenser dust every three months to ensure the normal operation of the equipment.

◦ In the event of an alarm failure or other failure, please refer to the instruction manual to clear the fault according to the prompts on the display board. If you can not eliminate the fault by yourself, please do not disassemble it. Please contact the after-sale maintenance personnel to help eliminate the fault.
