5.7 Shutting Down the Pump
Observe the following precautions before interrupting the operation or before shipping the
pump:

Rinse out any solvents if necessary. Fill the pump with methanol or a similar alcohol,
such as 2-propanol or ethanol. If a buffer is used as a part of the mobile phase, flush the
system with several volumes of methanol/water (50:50) before it is shut down. This will
prevent salt buildup inside the unit.

If operation is interrupted for more than 5 days, Dionex recommends removing the
Pharmed
®
tubing from the peristaltic pump. To remove the tubing, slightly press the lever
to the left, remove the tubing, and release the lever. This will avoid that the tubing
remains compressed and does not relax, thus blocking the wash solution.

If operation is interrupted for more than one week, fill the pump with methanol or a
similar alcohol, such as 2-propanol or ethanol. If the solvents in the pump are not miscible
with water, use an appropriate intermediate solvent.

Rinse out buffers or solvents that form peroxide.

Turn off the lamps in any UV or RF detectors that are connected to the pump. This will
prevent evaporation of the solvents in the flow cell.

When using an electrochemical (EC) detector with the pump, always turn off the potential
to the EC cells
before shutting off the pump flow to prevent damage to the cells.

If you want to ship or move the pump to a new location, be sure that no liquid remained in
the waste line of the rear seal wash system. (The waste line is routed on the pump bottom
to the drain port.) If necessary, lift and tilt the pump from the left side of the enclosure and
wait until no more liquid leaves the waste line.

Ship the pump only in the original shipping container and observe the packing
instructions. Shipping the pump in anything other than the original packaging voids the
warranty. For more information, see the warranty statement in the terms of sale.
If you are running Chromeleon, you can set the pump and HPLC system into the standby
mode or automate system shutdown.
