2.6 Installing the eluent path
2.6.1 High-pressure pump – Removing the transport security
screws
The pump head is locked with three transport security screws 13 in or-
der to prevent damage to the pump drive during transport (see Figure
2). These transport security screws must be removed before placing
the high-pressure pump into operation. Also remove the red sticker at-
tached to the pump head 24.
The three transport security screws must be refitted every time before
a major transport operation of the pump in order to avoid damage to
the pump head.
2.6.2 Connection MPak → high-pressure pump
The eluent MPak must be connected to the pump head 24 via the tub-
ing connection 23 6.1837.000.
First connect the end at the pump head and then, not before, connect
the end at the MPak output. The eluent will start to drain out if you
connect the end at the MPak output first.
Procedure when connecting the tubing connection:
1 Connect the tubing connection using the PEEK
coupling to the pump head
• Connect the tubing connection 23 6.1837.000 using the
PEEK coupling 55 (already pre-fitted to the tubing) to the
capillary inlet of the pump head 24.
2 Connect the tubing connection to the eluent MPak
outlet
• Connect the other end of the tubing connection 23 to the elu-
ent MPak outlet (pierce the connection and turn it through 90°
clockwise).
