EcoFlow 4000 - Operation

15 |
Operation
• Read the Safety Guidelines before use.
• Do not use the generator in a closed space as the exhaust fumes may result in a loss of
consciousness or even death. Use it in a well-ventilated place.
• Do not connect the AC Output Socket with any electrical equipment before starting the generator.
Note: The ambient temperature range for the generator is −15 to 40(5°F to 104°F) in gasoline mode and −5 to
40 (23°F to 104°F) in LPG mode. Generators can operate under standard atmospheric conditions, which include an
ambient temperature of 25(77°F), atmospheric pressure of 100 kPa, and relative humidity of 30%. However, when
the temperature, humidity, or altitude exceeds standard atmospheric conditions, the generator’s output may decrease.
Extended operation under high temperatures (>35>󾙛󾙗) can also affect the generator’s lifespan and its internal
battery. Additionally, using the generator in small spaces may require reducing the output to prevent overheating.
Generator Startup (4 Methods)
2
a. Electric Start Button
Press and hold the Electric Start Button for 2 seconds to turn on the generator.
Note: To conserve battery power, if the Engine Switch is in the ON position but the generator is not
running, power will be disconnected after 3 minutes, and the LCD screen will turn off. In this case, press
the Electric Start Button to activate the screen display then keep holding the button for 2 seconds to
execute the start-up program.
b. Manual start
Pull the Manual Starter Grip until the line tightens, then push it forcefully.
Note: Hold the generator to prevent it from bumping while you pull the cord. Do not let the starter handle
spring back towards the generator. Gently return the handle to its original position to avoid damaging the
starter.
c. Self-start
When connected to an EcoFlow power storage device, the generator will start automatically to charge the
device if the device has a low battery. Additionally, the storage device can also supply power to start the
generator, extending the generator’s standby time and ensuring its self-start performance. For details,
refer to "Charge DC Batteries" (Page 17)
d. App start
For details, refer to "EcoFlow App" (Page 18) to download the app.
Note: When the ambient temperature is below 0 °C, the engine needs to warm up for 3 minutes after
being started, during which time no load should be loaded.
