Connections (figs. 1, 2, 3 and 4)
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.
Filter replacement with cartridge filter (fig. 6)
Unscrew the filter plug in the cover with a 4 mm key and pull out the cartridge filter. If necessary, insert a screwdriver between filter and plug and carefully twist the filter out.
Scrap the filter and fit a new one onto the plug! Reassemble the cartridge filter and tighten it.
Changeover between 1-pipe and 2-pipe operation (figs 7 and 8)
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)
