I would have tried to get you going as fast as possible, but when you have a business things are different. If you have any commercial equipment it is always good to have a source for answers. Model Numbers and Brand Names listed someplace where you know just what you have and know who to call without having to get into an expensive repair trap. I'm not saying that those that came out overcharged you but it does happen a good bit of the time. If I can help feel free to ask here or through my websites, Thanks, John Tripp/AKA Sea Breeze
