AboutJ Cook Expertise With 25+ years experience, I am familiar with residential, commercial, and industrial HVAC equipment including but not limited to boilers, chillers, reciprocating and screw compressors. I am trained in all manners of control wiring.
Experience I currently have three HVAC licenses and Refrigeration license by the State of North Carolina. I have been in this field for over twenty years. I have been a service technician for a contractor and also worked at a state college in the repair and maintenance of steam lines and equipment. I am currently the Building Maintenance Superintendent for a municipality.
Question I need to get a wiring diagram for this unit. There is a number in the upper right hand corner of the current wiring diagram as follows: D9921901 rev O. We have had the motor that pumps the glycol rebuilt after it burned out and it isn't working now that it has been reinstalled. Ex husband thinks there is a wiring problem, but the lower half of the current diagram is missing.
Answer The only resource for a diagram will be the manufacturer. On most manufacturer web sites there is a location to download a diagram with the unit model and serial number. If not, the manufacturer can be contacted and they will directly email a diagram. Thanks J
