GENERAL DIRECTIVE FOR DAMAGE REPAIRS IN SPRAY/DRY BOOTHS
In case of damage repairs to a car with an LPG system, the LPG tank must be removed when the car is
placed in a spray/dry booth with a drying temperature higher than 60°C. Otherwise, the opening
pressure of the overpressure safety valve will be exceeded.
GENERAL DIRECTIVE FOR DISMANTLING LPG SYSTEM
When a vehicle with an LPG system is dismantled, be careful with the LPG tank, including pipes, due
to possible remaining pressure in these parts. Also remove LPG tank before the vehicle is crushed.
GENERAL DIRECTIVE FOR EXTREME TEMPERATURES
Extreme temperatures and the fuel composition can influence the operation of the LPG system. It
may take longer for the system to switch from petrol to gas. In extreme situations the system may
switch back to petrol, because the minimum conditions for the proper system operation are not met.
LPG FUEL QUALITY
The LPG must be as specified in the DIN EN 589 regulation at a minimum. If a fuel quality other than
specified is used, all terms of guarantee become void.
VALVECARE (OPTIONAL)
General
ValveCare is an additive dosing device developed exclusively for the Prins SilverLine-2.0 system.
ValveCare is used for the correct dosage of additives which prevent excessive valve and valve seat
wear. These additives are added to petrol, but not to LPG/CNG.
Diagnosis
For diagnostic purposes a beeper is integrated in the SilverLine-2.0 system switch. The following
warnings regarding ValveCare may occur:
The diagnose/system check LED flashes
Diagnosis: The ValveCare fluid in the bottle is empty and the bottle must be replaced as soon as
possible. It is still possible to drive on LPG for a maximum of 60 minutes, before the
system automatically switches back to petrol.
Action: Replace the bottle for a new bottle of ValveCare fluid (see page 5). The system will
switch back to LPG automatically. If necessary contact a Prins dealer for a new bottle
of ValveCare fluid.
Buzzer beeps + diagnose/system LED illuminated brightly (fuel level indication LEDs off)
Diagnosis: An error has occurred in the system. It is not safe to drive on LPG. Therefore, the
system will automatically switch to petrol.
Action: Switch off buzzer by pressing the fuel selector switch. Consult your Prins dealer.
