Dismantling and assembling

9.2.1 Remove housing parts
9.2.1.1 Cover for electrical connection
The cover (1, Fig. 902) can be carefully levered off using a
blunt blade in the areas marked "X".
9.2.1.2 Grilles (optional) for cold air inlet and hot air
outlet
The grilles (6, Fig. 902, optional) can be released by twisting
them out of the latch and pulled off toward the front.
9.2.1.3 Covers for cold air inlet and hot air outlet
Both covers (3 and 5, Fig. 902) can be released from the latch
and removed at the top and bottom by pressing in the 4 lock-
ing lugs of the upper and lower shell (2 and 4, Fig. 902) with
a suitable tool.
9.2.1.4 Top shell
The upper shell (2, Fig. 902) can be lifted off after removing
the covers for the cold air inlet and hot air outlet.
9.2.1.5 Bottom shell
Remove base seal.
By slightly spreading to the side on both sides at the lower
shell (4), in the "Y" areas, the latch is released and the shell
can be separated from the drive unit. Also remove the 4 insu-
lators (7).
9.2.2 Fit the housing parts
9.2.2.1 Bottom shell
1. Make sure that the 4 insulators (7) are properly
positioned on the heat exchanger.
IMPORTANT
To avoid crushing the cable, ensure proper routing of all ca-
bles between the cooling ribs of the drive unit and heat ex-
changer.
2. Expand the bottom shell (4, Fig. 902) slightly at the side
and fit it to the heater from underneath until the securing
pins on the heater engage in the holes in the shell.
3. Fit a new base seal.
