no more air escaping from the connection hose:

Fuel oil consumer installations should be checked for perfect condition by a specialist
company, or specialist company under water law where applicable, before initial start-up.

be started up.
Filter cup partially filled
Air and volatile oil components can evaporate out of the operating medium from an air / gas
cushion in the filter cup and accumulate in front of the moistened filter element. Particular
attention should be paid to this when using single conduit filters and low flow rates. The
interior of the filter element, which cannot be seen, is however still completely filled with
operating medium so that a filter cup which is only partially filled with operating medium has
no effect on safe operation.
