A/C Heater System Deodorizing

A/C-Heater System Deodorizing

The A/C System Deodorizer, product EP-1710-FF, is a full-strength deodorizer which requires no dilution or mixing. Each vehicle treated will require 10 fluid ounces to complete the procedure.

The A/C System Deodorizer can be applied using the A/C Disinfectant Sprayer Unit (Rotunda model 134-00055), a siphon type sprayer, or a refillable aluminum or stainless-steel aerosol paint sprayer (touch-up guns provide better access).

1. Set the A/C control to the NORMAL A/C position. On vehicles equipped with a manually operated fresh air I recirculate air door, set the door to the fresh air position.

2. With the blower motor operating at high speed, spray three ounces of the deodorizer product into the fresh air inlet.

3. Set the A/C control to the MAX A/C position. Move the temperature control lever to the full cold position. On vehicles equipped with a manually operated fresh air / recirculate air door, set the door to the recirculate (interior air) position.

4. With the blower motor operating at high speed, spray 1-1/2 ounces of the deodorizer product into the recirculate air opening (located in the passenger side foot area of the vehicle). Set the temperature control to provide full heat and spray an additional 1-1/2 ounces into the recirculate air opening.

5. Shut the blower motor off.

6. Spray equal amounts of the remaining four ounces of the deodorizer product into each of the air outlet openings (defroster, instrument panel registers, and floor ducts).

7. Allow the vehicle to sit for approximately 30 minutes before returning to the customer.
