Connections
Connections (fig. 1)
Bleeding
- Bleeding the oil pump is only necessary on 1-pipe systems.
- Bleeding is only possible at the P-port. On 2-pipe systems, the pump is automatically bled through the return pipe.
Filter replacement with cartridge filter (fig. 2)
- Unscrew the filter plug in the cover with a 4 mm key and pull out the cartridge filter. Insert if necessary a screwdriver between the filter and plug and carefully twist the filterout. Scrap the filter and press a new filter onto the plug!
- Reassemble the cartridge filter and tighten it slightly.
Conversion from 1 to 2-pipe operation
Conversion from 1 to 2-pipe operation (fig. 3)
-
1-pipe operation: without screw
-
2-pipe operation: screw fitted
Suction line lengths in meters
- The table is applicable for standard gas oil (Heizöl-EL) having a normal trade quality per applicable standards.
- When starting up a system with an empty pipe, the oil pump should not operate without oil for any more than 5 min. It is presumed that the pump contains some oil before starting up.
Attention
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).
