Bleeding
Bleeding the oil pump is only necessary with 1-pipe systems. On 2-pipe systems the pump is automatically bled through the return pipe.

Filter cleaning/filter replacement with ring filter (fig. 5)
Remove the four screws with a 4 mm hexagon key. Take off the cover. The filter can then be taken out for cleaning or replacement.Danfoss-BFP-11L3

Suction line lengths in meters
The tables apply to a standard fuel gas oil (Heizöl-EL) of normal commercial quality to current standards. When starting a system with empty piping, the oil pump should not be allowed to operate without oil for more than 5 minutes.

Attention!
BFP 20 pumps are without a solenoid valve. The oil pumps are used only for oil burners.

Please note that the solenoid valve must be replaced after 250.000 operations or 10 years (approved life expectancy)
