I removed all miscellaneous items from the vacuum oven and set the maximum temperature from 320°C to 200°C on the red dial with a flathead screwdriver. I connected the included plastic tube to the vacuum port and tightened with the included hose clamp. I couldn't tighten the hose clamp as much as I would have liked because of the limited access behind the oven. I want to move the oven and fix this before we turn on the pump, although it might be fine as is.

I set up the Agilent IDP 3 vacuum pump. To its KN16 port, I attached a rubber o-ring and a KN 16 to 5/16 " hose adapter from Ideal Vac. I tried to use the Ideal vac KN 16 clamp, but it's unusable. I borrowed a KN 16 clamp made by LDS Vacuum from the Hutzler Group, and this works as intended. I attached the hose from the oven to the adapter and tightened the hose clamp. I was able to tighten this hose clamp much more than the clamp on the oven.
