I have moved my Danby DPAC120068 Designer Air Conditioner to my basement to use it as a dehumidifier. What do I need to do? Do I vent the unit still?

Is there a reason not to just go to the Danby site? Support Danby includes phone support, email and "Find Parts" Even if their source is out you should at least be able to find the correct part number, then Google Danby (part number).
You could also look to see if generic flexible vinyl tubing/hose can be substituted. It's doubtful that Danby created their own hoses.

I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881

I have had the same problem with mine. Try to tape the small water container drawer shut. Restart the unit and see if the beeping is beepless.

Hi,
The A/C will be on when dehumidifying... that's how it does that...
If it is not collecting water, it is probably because the humidity is too low in the house already...

I would give it more time....

Kelly, you can contact Danby Customer Support at 800-263-2629.

Hope this helps you find the parts you need.

type Danby air conditioners in search bar.

The manufacturer suggests, even though state not required, to leave
required ac termination kit in place even in dehumification mode.
This should reduce your energy conflict.

I have heard other people do this I am not sure

Hello. I can help you. For safety use a piece of galvanized duct pipe, of the correct diameter and clamps. These are common items available at most any hardware store.

Adding on with more plastic hose is a fire hazard.

it needs to travel on a downward slope either outside your home or into a bucket, so condensation can drain.

Maybe, the compressor isn't starting? I'd take it back to where you purchased it.
