hi guys, hope someone could help out. i have a 3 year old climatemaster water cooled ac hooked up. i wanna make sure its done right. there is a valve on the 'water out' side. the guy that sold it to me said adjust the flow till the water coming out is 100 F. thats about 45F difference than whats going in. climatemaster tech said thats wrong. there should only be around 15F difference between in and out. and that i really sould be measuring pressure drop instead. so i installed pressure and temp guages on the in and out. instructions say adjust till theres around 6 psi pressure drop. i'm not getting any pressure drop at all. so i ask the climatemaster techie, he doesnt want to help, said call a technician. so any techies out there that can help me hook this thing up?
