Common Questions
Where is the refigerant kept when pulling a vacuum?
When you have to open the system after you've changed a component, it's a good time to pull a vacuum.
This unit will work for a refigerant cooling system.
If you use it on a home type AC unit you will need different adapters to fit the ports on the vacuum pump.
The quick connects on the manifolds are blocked, so does anyone know the purpose for the included quick connect fittings?
If the high/low couplers don't seem to open when they are turned to "open", that's a problem with your vehicle.
How log have you owned?
It works great, but I bought another fitting that connected to the freon can, and it didn't fit.
Cany tanks and cans are used to fill your system.
I've used it 4 times and it works well, I just added oil as instructed by the kit.
