Flushing

The external piping system must be thoroughly flushed before the engines are connected and
fuel is circulated through the engines. The piping system must have provisions for installation
of a temporary flushing filter.

The fuel pipes at the engine (connections 101 and 102) are disconnected and the supply and
return lines are connected with a temporary pipe or hose on the installation side. All filter
inserts are removed, except in the flushing filter of course. The automatic filter and the
viscosimeter should be bypassed to prevent damage. The fineness of the flushing filter should
be 6 

μ
