How Do You Safely and Effectively Drain the Unit? 

  • Unplug your Whynter portable air conditioner from the power outlet, and move it to an area that won’t be damaged by any water that might spill out of the unit during draining.
  • You will notice a small spout at the bottom rear side of your air conditioning machine, which serves as the drain for the unit.
  • Place a bucket or container underneath the drain spout to catch any water that comes out while draining.
  • Locate and remove the side panel of your air conditioning machine. This will expose the interior parts of your air conditioner, including the condensate pan, compressor, fan, and evaporator.
  • Use a flathead screwdriver to loosen the three screws at the side of the condensate pan and remove the panel, being careful not to damage any components.
  • Slip one end of a garden hose onto the drain spout on the bottom rear side of your air conditioning machine and attach it tightly with electrical tape.
  • Place the other end of the garden hose into a nearby drain or bucket to allow for proper drainage, and make sure that it is securely attached with electrical tape.
  • Turn on the power switch and fan control knob on your air conditioning machine and set it to “cool” and the desired temperature setting.
  • Wait for the air conditioner to start draining. This will take a few minutes, and you should be able to see the water slowly dripping from the garden hose into the drain or bucket.
  • When no more water is coming out, turn off your air conditioner and unplug it from the power outlet.
  • Remove the garden hose from the drain spout and return the condensate pan to its original position, securing it with screws.
  • Reattach the side panel of your air conditioning machine and plug it into a power outlet.

Following these steps will ensure that you can safely and effectively drain your Whynter portable air conditioner. Doing this regularly can help to keep your machine running smoothly and efficiently for years to come.
