There is a separate transformer in the refrigerator package. Only the transformer can be plugged into the 110V power supply!!!Parameters：Model：DW-86W20Size：780*410*515mmInner Size：327*200*305mmTemperature：-86 DegreeInput Power：270WVoltage：110V/60Hz（Equipped with a transformer, which can convert 110V voltage）Defrost：ManulPackage：Wooden Box Package easy to move： The ultra-low temperature refrigerator weighs 49KG (110LB) and can be easily moved by adult men. Safety buckle： The refrigerator lid has a self-locking function to ensure the airtightness of the refrigerator Ultra-low temperature The minimum temperature of the refrigerator can be switched from 0 to minus 86°, and the precise temperature control panel Fast cooling It only takes 1 minute to freeze the frost (pictured above) and can be cleaned with the snow shovel and gloves included in the package Product includes: refrigeratorGlovestransformermanual Good sealing Silicone gaskets make refrigerators more airtight Parameter descriptionSP – Shutdown temperature. When the temperature is lower than or equal to the shutdown temperature SP, the compressor will stop running (r1 to r2).r0 — return difference temperature. When the temperature is higher than the startup temperature (SP+r0), the compressor runsr1 – Minimum shutdown temperaturer2 – The maximum shutdown temperatureP1 — Temperature calibration. Used to compensate for measuring temperatureP4 — Probe shows temperature with or without decimal pointA0 – Overtemperature alarm return error. When the temperature is lower than (high temperature alarm value -A0) or higher than (low temperature alarm value +A0), cancel the high temperature alarmA1 — Overtemperature alarmHigh temperature alarm value = (SP+R0+A1)Low temperature alarm value = (SP-A1)A2 – The overtemperature alarm is prohibited during power-on. The alarm of overtemperature is prohibited during the A2 time when the power is just onA8 — Overtemperature alarm delay. When the temperature exceeds the limit, the timer will start. When the time reaches A8, the alarm will startH5 – Advanced parameter access passwordc0 — Minimum downtimec2: Compressor start-stop state when the probe is faultyP4 – Indicates whether to display decimalsParameter settingSetting the temperature (SP) is the only parameter that can be set without entering a password.Press the SET key.SP will appear on the screen.Press SET again. The SP temperature is displayed.You can use ↑ and ↓ to adjust the SP temperaturePress SET to confirm setting temperature.Press the SET key and DOWN key at the same time to exit the parameter setting, or wait for one minute, the display will automatically exit the setting interface.out prior notice.Press and hold the SET key for 8 seconds, and the screen will display the input setting password (the factory initial password is 0).Users can use the ↑ and ↓ keys to change the password.Press the SET key to enter the password. If the password is correct, enter the first parameter setting (SP).Use the ↑ and ↓ keys to set the desired value.Press SET key to exit parameter setting.Repeat until all parameters are set.Press the SET key and DOWN key at the same time to exit the parameter setting, or wait for one minute, the display will automatically exit the setting interface.Turn off the thermostat and press and hold the SET key while powering on to restore the password to 0Led indication, buzzer and display informationThe OUT on the LCD screen indicates whether cooling is taking place. When cooling is going on, the display light is steady on; While the thermostat is waiting for minimum downtime (50% on 50% off)Normally, the temperature of the probe will be displayed on the display.In the case of alarm, the displayed information is as follows (alarm indicator light on, buzzer sounds) :000 — Temperature probe rod fault — short circuit fault ALH — high temperature alarm ALL — low temperature alarmAlarm confirmationIn case of alarm, the internal buzzer and alarm indicator are activated to display the corresponding message. The buzzer can be silenced by pressing the SET key.PaymentDelivery detailsTerms of salesAbout usContact usPaymentPayment should be completed within 4 (Four) days of auction closing.
