The air conditioning system produces an odour (Step 3 – Base Table C)

Under specific conditions, bacteria can form on the surface of the evaporators and cause an "unpleasant odour" inside the vehicle.

Treat the evaporator with any of WAECO’s cleaning products, such as Refresh-o-mat.

Recommendation for customers:
Turn off the air conditioner for a few minutes before the vehicle is stopped. Allow the compartment ventilation to run for a few minutes (which will dry the evaporator, which is otherwise a breeding ground for bacteria).

If the “unpleasant odour” continues to persist after implementation of the above steps, contact WAECO’s technical service department.
