Installation
CAUTION:
- The legal provisions on page 1, relating to the installa-
tion of the heater, must be observed
- When installing the Thermo 90-ADR in vehicles de-
signed for the transport of hazardous materials the re-
quirements laid down in ADR 002 and ADR 003 (Techni-
cal Guidelines relating to the ordinance of transporting
hazardous goods on the road) must be fulfilled in addi-
tion to those of the StVZO.
- If the water heater is to be operated in a separately in-
stalled heating system, it is mandatory that the installa-
tion drawing be submitted to Webasto for approval
prior to installation.
NOTE:
The different vehicle-specific installation conditions should
be taken into account.
Installation Location
The heater should be installed at a level as low as possible
so as to ensure automatic venting of the heater and the cir-
culating pump. This is of special importance as the circulat-
ing pump is not of the self-priming type.
Type Plate
The type plate must be located in a place where it is pro-
tected against damage and be easily accessible once the
heater has been installed (or else, a type plate duplicate is
to be used).
The years not applicable are to be removed from the type
plate.
