A/C Order Treatment Procedure

NOTE:
THIS PROCEDURE WILL NOT BE EFFECTIVE ON ODORS EMITTED FROM AREAS OTHER THAN THE EVAPORATOR CORE. FOR EXAMPLE: MILDEW ODORS DUE TO WET CARPET WHICH ARE CIRCULATED BY THE A/C SYSTEM. BE SURE YOU HAVE IDENTIFIED THE TYPE AND SOURCE OF ODOR BEFORE PERFORMING THIS REPAIR.

The A/C System Disodorizer(R) (F6AZ-19G210-AA or YN-18) is a full strength disodorizer which requires no dilution or mixing. Each vehicle treated will require 240 ML (8 fluid ounces) to complete the procedure.

NOTE:
THE ROTUNDA A/C DISODORIZER(R) SPRAYER 164-R4700 IS ONLY TO BE USED WITH THE YN-18 A/C SYSTEM DISODORIZER(R) AND SHOULD NOT BE USED FOR ANY OTHER PURPOSE.





The A/C System Disodorizer(R) can be applied using the Rotunda A/C Disodorizer(R) Sprayer 164-R4700. The disodorizer must be applied through the blower motor or the blower motor resistor/controller opening for proper coverage. Refer to the Disodorizer(R) Application Location Chart to determine which component to remove.

NOTE:
SPRAYER MUST BE CHARGED COMPLETELY FOR PROPER ATOMIZATION OF THE DISODORIZER(R). FAILURE TO PROPERLY APPLY THE DISODORIZER(R) AS OUTLINED IN THIS TSB ARTICLE WILL NOT ALLOW ALL OF THE MICROBIAL GROWTH TO BE CONTAINED AND WILL RESULT IN AN INCOMPLETE REPAIR.

1. Open vehicle windows.

2. Disconnect A/C cycling switch electrical connector.

3. Set the following:

^ A/C in vent or panel mode
^ Temperature at full heat
^ Blower at high speed
^ Engine running at normal operating temperature
^ Vehicles equipped with a manually operated fresh air/recirculate air door, set the door to fresh air position

4. Run at Step 1.3 conditions for 15 minutes (this Step will dry out the system).

5. Turn ignition off.

CAUTION:
BLOWER MOTOR RESISTOR MAY BE VERY HOT.

6. Remove and disconnect blower motor or resistor/controller (refer to Disodorizer(R) Application Location Chart) by referring to the appropriate Service Manual, Section 12 or Workshop Manual, Section 412-02.

7. Insert the A/C Disodorizer(R) Sprayer (Rotunda 164-R4700) nozzle into the blower motor resistor/control opening in the evaporator case and direct toward the face of the evaporator core. Spray the Disodorizer(R) until empty.

8. Wait 10 minutes before proceeding.

9. Reinstall and reconnect blower motor or resistor/control.

10. Repeat Steps 1-5.

11. Reconnect A/C cycling switch.

12. Allow vehicle to sit for 30 minutes before returning to customer.
