| Description and Operation The purpose of the air distribution system is to route air to the designated registers. This is accomplished when air enters the plenum through the fresh air inlet and is routed to the selected outlets by use of distribution doors. The incoming fresh air is passed through a pollen filter which is standard and is located under the air cowl trim panel on the front passengers side. There are two different filter elements available: - The standard pollen filter is capable of removing all airborne particles larger than three microns in size and cleans the air of pollen, dusts and diesel soot.
- The activated carbon combination filter is optional and has the same advantages as the pollen filter plus an effective active carbon layer, which neutralizes unpleasant adours and keeps the air free of ozone.
Air ducts route air to specific areas of the air distribution system. These areas are the floor ducts, panel registers, side window demisters and defrost nozzles. The instrument panel registers are adjustable and used to aim the discharged air to a required area. The floor ducts, side window demisters and defrost nozzles are nonadjustable. |
