3 Connection MPak pump tubing
The regenerant MPak and pump tubing are connected using the
"tubing connection to MPak" 23 6.1837.000:
•
First connect the end which is to be connected to the pump
tubing!
•
Pressure screw 52 4.422.4510 and coupling 55 4.455.4500
are already pre-fitted on the "tubing connection to MPak" 23
6.1837.000. Screw this coupling 55 4.455.4500 onto the cou-
pling 60 6.2744.110 plugged onto the left-hand end of the
pump tubing (flow inlet).
•
Latch the other end of the "tubing connection to MPak" 23
6.1837.000 at the outlet of the regenerant MPak.
