Refrigerator-freezer is sensitive to environment temperature. Refrigerator-freezercan't work normally if it is installed in other environment. Please use afterenvironment improvement.It is not allowed to install refrigerator-freezer outdoor. When therefrigerator-freezer is drenched by rain, it may cause electric leakage orelectric shock.To enable the refrigerator-freezer to work normally and obtain best performance, the installation siteof refrigerator-freezer should meet the following conditions:It can't be installed in small airtight space, and the door of room for placement should not besmaller or lower than this product, it should at least allow normal in and out of product, or it maybe hard to repair fault machine, nor timely recover machine and cause stored goods damage.Installation ground must be firm and flat.Good ventilation, avoid direct sunshine.Don't share socket with other equipment plug, plug and socket should be firmly connected.Don't bend or press power wire.If the power wire should be lengthened, the sectional area of extension cord should not be lessthan 3mm², and not be longer than 3m.Inspect the working voltage before use, voltage regulator with proper motor load should beconsidered in area with unstable voltage. To enable the normal input voltage as 220V ± 10%, thepower of voltage regulator should be greater than 400W.Refrigerator-freezer should be reliably earthed.If power socket has ground wire, check whether it is well earthed before use.If the power socket doesn't have ground wire, be sure to install the ground wire by professional technician.Refrigerator-freezer should not be grounded through gas pipe, water supplytube, telephone line or lightning rod, or it may cause electric shock.The power plug must be accessible after installation, so that it can be unpluggedin emergency. Nothing can block the ventilation opening of refrigerator-freezer.22 7Install a recyclable charging battery in refrigerator-freezer, and when it is to achieve the service life,please contact local battery recycle agent for inspection, or correctly discard the battery.The battery in refrigerator-freezer is for power outage alarm, and it is in electric cabinet.Electric cabinet has high voltage electrical apparatus element.To prevent electric shock, the cover should be opened by professional engineer ormaintenance man.1. Unplug power plug from socket;2. Remove the screws from electric cabinet cover by screw driver;3. Unplug the connection plug of battery;4. Dismantle the fixed clamp of battery, and take out battery;5. Recycle or correctly dispose battery as required.When replacing battery, make sure the brown wire is connected to battery anode, blue wireis connected to battery cathode. Or it is easy to burn the charging circuit of computer board,which will not be able to charge battery.Position of batteryTake out the batteryRechargeable Battery RecyclingThe brown wire is connected to battery anodeThe blue wire is connected to battery cathodeProduct InstallationInstallation environmentEnvironment temperature: 16°C to 32°C, the ideal temperature is 18°C to 25°C, and airconditioning system should be used when necessary.Environment humidity: Lower than 75%Rh.To avoid a great deal of dust.To avoid mechanical swing or vibration.The altitude of working position of refrigerator-freezer: Lower than 2,000m.Input voltage: Within 220V ± 10%.Installation site
