Section 4, Installing the Fuel System
International Thermal Research 4-3
Ensure that fuel lines are always protected from contamination by
foreign material. When installing or servicing, seal off ends to
prevent contamination. After installing, you may also wish to flush
the fuel line to rid it of any air and any foreign material.
4.4 Procedure
To complete the fuel system installation:
1 Install the inline fuel filter. The optimal location is on a
compartment wall next to the POLAR™ HD Heating
Module, inline between the fuel tank and the POLAR™ HD
Heating Module.
2 Connect the fuel line to the dedicated fitting on the main
diesel fuel tank.
3 Inspect the supply fuel line for any loose connections or
damage. Fittings must be airtight.
4 If desired, install a shut-off valve on the tank side of the
fuel filter to allow shutdown and filter service.
5 Install a shut off valve on the fuel line just before the inlet
to the heater.
