I am trying to find a picture of the desiccant filter installation on a 2006 duacto it is a cartridge type that goes into the condenser , trying to see if a spring goes in it and where it goes in . Also if any one knows if there is another type of filter that fits that I can buy in Australia or if I can refill the cartridge with the beads of another filter any help on this would be great . the number of filter is 51733521 I believe the condenser is a 244
