Getting Started
How to Install
When using the cooling or heating function, please make sure you’ve installed
the exhaust duct and adapter cover to Wave 2, otherwise it will affect the air
conditioner’s working efficiency. It is recommended that the space is within
20m3 for better working performance.
Indoor Use
When the air conditioner is used in an enclosed space, you can get rid of
waste air through the exhaust ducts. The exhaust duct should not be
excessively stretched or bent when it is connected to avoid affecting the air
conditioner’s working efficiency. 
DIY Window Vent Board
A window vent board is included with Wave 2. The board is pre-cut based on the
diameters of the exhaust ducts. You can apply it to your truck, RV or home
windows, fill the gap between the board and the window, and vent the exhaust
air through the ducts. 
It is not suggested to use the exhaust duct in rainy and snowy weather to avoid damaging the products.
Outdoor Use
When the interior space is small or noise avoidance is required, Wave 2 can be
placed outdoors and deliver cooling or heating through the front air outlet.
How to Power-on
This product supports multiple power supply methods. Open the charging port
cover before using it, then power on. Please close the cover to prevent dust
during charging, and wind the AC charging cable around the winder. 
For shutdown, please press and hold the power button before removing the charging cable. Do not directly remove the cable to avoid damaging the battery cell.
AC Outlet
Wave 2 supports an AC voltage from 100-240V. Please use the original AC
charging cable and make sure the working current of the outlet should
continuously exceed 10A. 
Battery pack
The EcoFlow Wave 2 add-on battery or EcoFlow portable power stations (DELTA
and DELTA 2 series are recommended) can be used to supply power to Wave 2.
These products and cables can be purchased on official EcoFlow channels.

Solar Panel/Car Charging Port
When charging using a solar panel, please confirm that the output voltage and
current of the solar panel is within the specified range (11-60V/13A), and
check the solar panel user manual.
When charging using the car charging port, turn on the engine first to avoid a
failure to start if the car battery is too low. Wave 2 supports 12V/24V car
charging and a maximum charging current of 8A. Make sure that the car
charging port and charging cable are securely connected to the cigarette
lighter. 
If car or solar panel power is low or voltage is unstable, only fan function
will work.
If the cooling/heating function is required, connect the Add-on
Battery/portable power station.
How to Drain
Wave 2 has drain-free function. When the cooling function is on, condensation
evaporates through flash distillation. When the heating function is in use or
the ambient humidity is too high, condensation cannot be drained completely
using flash distillation. Check the water level indication on the LCD for more
information. When it cannot collect anymore water, Wave 2 will shut down
automatically (switch to fan function if it is currently in cooling mode.).
Do not shake or move the air conditioner to avoid water leakage.
External drainage: When the drain pipe is connected to the drainage outlet,
press and hold the speed button for 3 seconds, and LCD displays [External
drainage indicator]. Press and hold it again to turn off drainage function.
If not turned off, the product will continue to drain out when reaching high
water level. 
Manual drainage: A small amount of residual water will be left at the bottom of the water tank after external drainage. Please remove the connecter, and tilt the unit back slightly until the condensation is completely drained.
How to Clean
The air inlet may get blocked with large dust particles and impurities in
the air during outdoor use. Regularly remove the front and rear air inlet
filters, clean them with a damp cloth using a mild detergent, dry them in the
air, and then reassemble them. 
Care and Maintenance
- Please close the socket cover after the unit is stored to prevent dust.
- After the unit is stored after shutdown, manually drain the unit to prevent bacteria breeding in the damp during long-term storage and avoid overflow of water when it is moved next time.
- It is recommended to store this product within the range of ambient temperature range of 20°C-30°C (68°F-86°F), and keep this product away from water sources, heat sources, and metal objects.
