4.2 Installing Ultraheat in Truma S 3004
4.2.1 Preparing the installation box
There are two versions of the installation box. The dif-
ference is in the perforation for the temperature switch.
The two versions require different work steps.
If a perforation is present, break this out. Then insert the
temperature switch with a screw.
If there is no perforation, the respective holes and open-
ings must be made using the enclosed templates. Then
insert the temperature switch with two screws.
CAUTION
Risk of cuts from sharp edges on the instal-
lation box.
Wear safety gloves.
