Hi .. it's eng.Khaled from Egypt
I've already bought a chiller from McQuay International and its model is PHH079 from 1988 and now there's a problem in it, when it starts up with Star connection it works normally but when it converts the electrical signal to Delta connection it stops !!!! so may be there's a problem in contactors or another thing ?!!!
I need just a technical support to how deal with this problem ?! .. please inform me with solution.
thanks
