Foreword
This installation documentation applies to Fiat Ducato 250 / Multijet Diesel vehicles - for validity, see
page 2 - from model year 2006 and later, assuming technical modifications to the vehicle do not affect
installation, any liability claims excluded. Depending on the vehicle version and equipment, modifications may be necessary during installation with respect to this ‘installation documentation’.
However, the stipulations in this ‘installation documentation’, the ‘operating instructions’ and ‘installation instructions’ for the Thermo Top C must always be observed.
The corresponding rules of technology and any information from the vehicle manufacturer should be
observed during the installation work.
General Instructions
Installation should be carried out according to the general, standard rules of technology. Unless specified otherwise, fasten hoses, lines and wiring harnesses to original vehicle lines and wiring harnesses
using cable ties. Insulate loose wire ends and tie back. Connectors on electronic components have to
audibly click into place during installation.
Sharp edges should be fitted with rub protection. Spray unfinished body areas, e.g. drilled holes, with
anti-corrosion wax (Tectyl 100K, Order No. 111329).
When installing a programmable control module (e.g. a PWM Gateway), the corresponding settings
must be checked or adjusted before the installation.
Special Tools
- Torque wrench for 2.0 - 10 Nm
- Hose clamping pliers

Coolant Circuit
WARNING!
Any coolant running off should be collected in an appropriate container. Route hoses kink-free. Unless
specified otherwise, always fasten using cable ties. Position clamps so that other hoses cannot be
damaged. The heater must be filled with coolant when installing the hoses.
The connection should be modelled on an ‘inline’ circuit and based on the following diagram:
