Coil Notes & Sample Contractor Coil Code Strings Note: ALL Central Station Air Handlers use "Contractor" style coils. Contractor Coils are ordered as SEPARATE LINE ITEMS on the GO/General Order (Example: 976230-017), so they DO NOT have standard nine digit Daikin Applied part numbers. When a replacement Contractor Coil is required a Contractor Coil Quote needs to be prepared. To quote a replacement Contractor Coil it is necessary to obtain model and serial number information from the unit nameplate and then contact Daikin Applied. If the unit has more than one coil it will be necessary to confirm which coil(s) are needed BEFORE quoting. Note that the sample code strings shown below are incomplete and DO NOT furnish enough information to correctly quote a Contractor Coil. GO and/or serial number information is required in order to properly quote a Contractor Coil. In some instances, coils were manufactured separately from the unit and may have a unique serial number such as 9Z12345-00. A coil with a serial number starting with a "9" was built in Scottsboro AL and may or may not have been installed in a unit before shipment.
