 Disconnect the PE conductor's flat-pin connector
from the inside, preferably on the chassis.
 Remove the cover completely from the chassis, and
place or lay it down somewhere safe.
Dismantling of the unit is now complete.
8.4.3 Cleaning the components with com-
pressed air
After removing the cover from the unit, you will be able
to access the components in the outer circuit, particu-
larly the condenser, the condenser fan and the com-
pressor chamber.
 Wear cut-resistant gloves when cleaning with com-
pressed air, so as to avoid injuries caused by sharp
edges inside the unit.
 When cleaning the components with compressed air,
blow dirt sideways out of the cooling unit.
 Alternatively, use a suitable vacuum cleaner to clean all
components.
8.4.4 Re-assembling the cooling unit
Once the cleaning work is complete, the cooling unit
must be sealed and, in the case of full internal mounting,
fitted back into the mounting cut-out.
 First, completely re-assemble the cooling unit.
It is assembled in the reverse order from dismantling
(see section 8.4.2 "Dismantling the unit"), in the same
way as for the initial assembly (see section 5.3 "As-
sembly procedure").
 For full internal mounting of the cooling unit, re-insert it
into the mounting cut-out.
 Make the electrical connection for the cooling unit.
