Solenoid valve 30012
The solenoid valve 30012 (available as accessory) prevents the tank from emptying in case the fuel system fails. The
fuel filter should be installed before the solenoid valve.
Our recommendations in the following installation configurations:
Preferred installation layout (solenoid valve 30012 is not
required)
1. Fuel level is below the heater/stove. See figure 1.
• No special accessories required
Solenoid valve 30012 is recommended
2. Fuel level may temporarily rise above the heater/stove (e.g. in
the fuel tank filler pipe or when the boat tilts). See figure 2.
• No special accessories required but solenoid valve 30012 is
recommended.
Less desirable installation arrangement (solenoid valve
30012 must be installed)
3. Fuel level is above the heater/stove. See figure 3.
• Less desirable installation arrangement
• Possible siphon problem
• Solenoid valve
30012 must be installed in the fuel hose near the
tank.
If the fuel level in the tank is above the device, a solenoid valve 30012 must be installed in the fuel line
immediately after the tank lead-through.
