1.
Carefully close the rear cover (3) on the electronic meter index head and make sure that
none of the internal wires are jammed during this process. Fix the cover in place by
tightening the screw (2) by hand.
2.
Seal the meter against unauthorized access again using the supplied safety seal (1).
3.
To do this, insert the ends of the sealing wire (7) into the holes in the seal (1) from both
sides.
4.
Then turn the crosspiece (8) in a clockwise direction until the wire has been inserted so
far that the crosspiece breaks.

Lubrication
Note:
MQMe Quantometers with permanently lubricated ball bearings (no oil pump)
are maintenance-free. MQMe Quantometers with oil pumps require regular
lubrication, see section 9, page 15.
Process for the first lubrication
1.
It is recommended that you only use oil sold by Metreg Technologies. A pack of oil for
the initial commissioning is supplied with the meter.
2.
Approved oils are: Shell Morlina S2 BL 5 or Shell Morlina S2 BL 10.
3.
Fill with oil before commissioning the meter and after correct installation as described
4.
Add the correct volume of oil to the oil reservoir and then pull the pump lever in a
horizontal direction.
5.
Depending on the size of the meter, the following strokes are required:
DN 50:
3 strokes
DN 80:
5 strokes
DN 100: 5 strokes
DN 150: 9 strokes
6.
After completing the lubrication process, the oil reservoir should be closed tightly again
to prevent any contamination of the lubrication system.
