Installation
Installation instructions for Solenoid valve 30012 (accessory)
The solenoid valve (30012) prevents the tank from emptying in case the fuel line
breaks.
The fuel fi lter should be installed before the solenoid valve.
In a fuel hose with a T branch, the solenoid valve must function with both connect-
ed devices. Connect the solenoid valve to a relay group (accessory) and the relay
group to the devices.
Two devices can also be installed to the fuel system by connecting both devices
through their own tank connections and solenoid valves. This way the relay group
is not required.
