Body Vac

Our facility just got donated 10 Body Vac in bed bathing systems. It is kinda of like a vacum cleaner if you ask me. You fill the tank with warm water, it has a temperature gauge on it and will give an error message if it is too hot. Room temperature takes about 15 minutes to warm the water. It has a place to put the soap/shampoo in. You also have to use defoming solution in the tank. The DON and I tried 2 different models, they donated 10 of these to our facility--brand new. Both the DON and I thought that the bath felt cold, the water was warm, but the sution causes the air to feel cool. If this system works it would be great for residents who are bedbound. I was wondering if anyone out there has used the Body Vac system. Currently all 10 are in the classroom, the saleman is going to provide the DVD that goes with them--maybe we are doing something wrong, but we followed the directions word for word.
If any one out there has used this system I would like some imput about it, at this point we have 10 units collecting dust because if I was the one getting a cold bath, I would surely complain.
