Refitting

- inner sliding races (arrowed in top right figures), teeth and inner surfaces that mate with cylindrical ridges of side distributor heater surfaces of square levers with toothed sectors (1 and 2) must be lubricated with vaseline;

- square levers with toothed sectors (1 and 2) must be fastened to the left side surfaces of the distributor heater unit so that the indicators (arrowed in the top left figure) are aligned with the triangles printed on the rack (3). - after connecting spirals at the end of the respective control cables on the cylindrical ridges of rack (3) and lever (4), connect sheaths on clips indicated by arrows in the central figure so that the distribution and mixer flaps move through their entire travel.

Refitting

To refit the evaporator - heater - distributor assembly, reverse instructions for removal, noting that pipes (6 and 7) marked by green and white stripes respectively must be fitted on left and right hand ducts of heater radiator marked by a raised dot in the same colour.

O rings of fittings connecting pipes (8) to pipes connected to expansion valve and evaporator must not be deformed; if they are replaced use only green rings which, unlike the black rings, are resistant to coolant R 134 A.
