Installation
Fuel connections
Things to note about the connections
The standard length of the fuel hose is 4 m (max 6 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 filter.
Country-specific requirements
The standard fuel hose is plastic. Please observe the country-specific require
-
ments with regard to the material for the fuel hose / pipe, the fuel filter and the hose
clamps. The inner diameter of a new replacement hose must be equal to the inner
diameter of the plastic hose.
Copper pipe and metal filters are available as accessories.
Fuel feed
If the lift height is outside the recommended 0.5–1 m, the fuel feed must be
checked and, if necessary, adjusted. 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. We recommend that the adjustment
be carried out by an authorised service shop.
Tank placement
1. The fuel tank should always be placed below the base of the device. (The fuel
surface level must be below the device.) When the fuel level is above the base,
the solenoid valve
30017
must be installed on the tank-side end of the hose.
2. The fuel tank can be placed in the base housing
4031
, or outside it, for exam-
ple, in the foundations of the house or a suitable protective box. Protect the
tank and the fuel hose from direct sunlight.
3. The fuel hose lead-through must be shielded by a metal cover pipe.
4. The standard length of the fuel hose is 4 m. It can be extended with a 2 m ex-
tension hose, which gives a total length of 6 m. Connect the hoses with bayo-
net couplings, which are twisted together.
