DRAIN HOSE CONNECTION - PORTABLE A/C
During Cool or Fan Mode (in low humidity), there should be no need for drainage. The air conditioner is designed to operate with some moisture in the collection tank to help increase its efficiency. However, if you are going to run the air conditioner in dehumidification (dry) mode, you can install a drain hose (10mm inner dimension) and place the open end in a suitable location, like a floor drain or run to the outdoors.
The drain steps for a portable air conditioner may vary from model to model. Refer to your owner’s manual for specific instructions for your particular model. Below are some examples of the back of a portable air conditioner. To drain the unit manually, remove the drain cap and tilt the unit to the back. On some models, there is an out and inner cap that must be removed. Use a shallow pan to drain the water. This is not supplied with your portable air conditioner.
