Installation
Fuel connections
Things to note about the connections
The standard length of the fuel hose is 4 m (max 8 m). Cut the fuel hose to a length
suitable for installation.
The lift height of the pump should be less than 2 m; preferably 0.5 – 1 m.
The fuel pipe must always have a Wallas filter. The fuel filter can be installed
either near the device, near the tank, or in another location where it can be easily
checked and replaced, when necessary.
Diesel engine fuel filters and/or separators are not approved for use. All soft con-
nections should be made with rubber or silicone hose which is resistant to diesel.
Country-specific requirements
The standard fuel hose is plastic. Please observe country-specific requirements
with regard to the material of the fuel hose/pipe and the fuel filter. The inner diam-
eter of a new replacement hose should be equal to the inner diameter of the plastic
hose. Copper pipe 300692 and metal filters 30016 are available as accessories.
Fuel feed
If the lift height exceeds 2 m, the fuel feed must be checked and, if necessary, ad-
justed. The fuel feed must also always be checked, if parts of the fuel system, such
as the pump or the electronics card, have been replaced.
Fuel system adjustments are device specific. These adjustments should only be
carried out by an authorized service shop.
Connection to a fixed tank
The device must have a dedicated connection with a fuel filter outside the tank.
Connection to a separate tank
Cap run-throughs and sintered filters are used on plastic tanks.
The fuel tank should be mounted securely.

The fuel connections must be tightened firmly so that the air cannot
leak into the hose. Always check the cleanliness of the connection
surfaces before tightening. Air leaks in the fuel system will cause the
device to malfunction.
