General instructions

The installation of the system shall be done in accordance with the installation manual provided by Prins
Autogassystemen.

Always disconnect the battery when installing the LPG/CNG system.

Do not place the main fuse into the fuse holder before having completed the installation of the VSI system.

The VSI computer has to be activated by means of the diagnosis software.

In the unlikely event the VSI computer fails, it will automatically switch over to petrol.
Never disconnect the VSI computer connector, unless you have removed the main fuse.

When installing the VSI wiring harness, ensure that it does not run near any of the ignition components.

Solder and insulate all electrical connections.
The wires in the loom are provided with numbers and text. The text on the wire explains the function of the wire.
The wire loom is not model specific, therefore is it may be necessary to adjust the length of the wires.
Ensure maximum care is taken when connecting wiring.
Make professional joints using solder and shrink sleeve. Do not stretch the wiring harness.

No component of the LPG/CNG-system shall be located within 100 mm of the exhaust or similar heat source,
unless such components are adequately shielded against heat.

Remove any internal burrs, after having shortened the LPG/CNG hose. (This guarantees the maximum flow
through the hose without pollution.)

If holes have to be drilled (wear safety glasses) in order to facilitate mounting the device frame, the reservoir
frame, the LPG/CNG cut-off valve, etc., the drilled holes must always be treated with an anti-corrosive, after the
burrs have been removed ( especially when mounting a exterior filler ).

After having completed the installation, check the whole system for gas leakage; use a gas leak detection device.

Fitting and maintenance is only allowed by Prins Autogassystemen selected LPG/CNG engineers.

Prins Autogassystemen is not responsible for any damages to people or objects as a result of changes to Prins
