Need flexible exhaust hose - Arctic Pro YPC-07C Faac7 Portable Air Conditioner

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

240 volt electric cord, and a flexible usually 4 inch, exhaust hose.

Install cord to drier.
Install flexible hose to driver using the clamps provided.
Install plug into the 50amp drier outlet.
Install the other end of the exhaust hose to the vent going outside.
Carefully move the drier back into position almost against the wall without crushing the vent hose..

Take a section of your old one and head over to any home center or hardware store and you'll find a a wide selection of flexible duct work that will meet your needs, inexpensively. There's really nothing special about the flexible duct/exhaust hose, that came with the unit.

Hope this helped you . Please let me know. Thanks.

F70 code is warning you that the exhaust vent airflow is insufficient.

• Check the exhaust hose in the rear of the machine and make sure it it not crushed or kinked. The vent pipe should be rigid metal not flexible foil or flexible plastic.

• If using dryer sheets, rinse the lint filter with hot water to remove filmy residue that can restrict airflow through the filter

• Inspect the outside vent hood for any blockages.

• The exhaust system may need cleaning. Cleaning kits are available at most home improvement centers.

U must remove the exhaust crossover pipe that goes from the front to the back exhaust manifold also the flexible air intake hose, spray the exhaust crossover pipe bolts with WD 40 before you try to remove them.

LONG dry time is an indication of a clogged or restricted exhaust. Clogged or restricted exhaust is the primary cause of failure in all residential dryers.
Check the exhaust hose in the rear of the machine and make sure it it not crushed, kinked or clogged with lint. The vent pipe should be rigid metal not flexible foil or flexible plastic. If everything in rear looks OK, check the outside vent hood for any blockages. If everything checks out, the exhaust system may need cleaning. Cleaning kits are available at most home improvement centers or this website http://www.linteater.com/.

If airflow is poor through the exhaust, the heater will fail and other protection devices, intended to prevent fires, will fail.

you can put an aluminum duct tape to the ripped portion just to stop hot air from venting from the damaged portion. or if the ripped portion is near the end where you put the flexible hose, then maybe you can move the flexible hose as far as it can reach as to cover the ripped portion of the vent pipe. then secure the flexible hose with a good hose clamp. i hope i was able to help

AF stands for 'Air Flow'. The machine is warning you that the exhaust vent airflow is insufficient. Check the exhaust hose in the rear of the machine and make sure it it not crushed or kinked. The vent pipe should be the rigid metal type not flexible foil or flexible plastic. If everything in rear looks OK, check the outside vent hood for any blockages.
