It is important that when you check the exhaust balance on the machine, you have the entire machine turned on. Usually, the blower will pressurize the inside of the machine and it will change the flow of the exhaust. Once the machine is all turned on and everything is running, you should be able to move back the entrance and curtain just a little to see the moisture or the mist kind of rolling right inside that area. You should see very little coming out of the entrance end. Another area to check and it kind of takes a trained eye, or if you have strong flashlight, when the machine is running you should be able to see the exhaust and the moisture within the system. It will be flowing towards the entrance and that’s what you want. As I said earlier, it is better to have any moisture or mist from the rinse section travel into the wash rather than have the wash or mist travel towards the rinses. If it follows the rinses, you don’t want that. Those are probably the two easiest ways to check.
