4.5 Set Up the Piston Seal Wash System
Replumbing the Seal Wash System (DP only) (Optional)
The standard piston seal wash system is designed for use with only one of the two
pumps in a DP module. When the DP is shipped from Dionex, the seal wash
system is connected to pump 1 (the bottom pump). If you want to connect the seal
wash system to pump 2 (the top pump), follow the instructions in this section.
NOTE Dionex offers an External Seal Wash Kit (P/N 063518)
for users who need to operate a piston seal wash system
for both pumps in the DP. Installation instructions are
provided in the kit.
1. Note the tubing connected from the peristaltic pump to the seal wash tube on
the secondary pump head on pump 1 (see Figure 4-1
). Disconnect this tubing
from the pump head and connect it to the seal wash tube on the secondary
pump head on pump 2.
2. Disconnect the seal wash reservoir inlet line from the primary pump head on
pump 1 (see Figure 4-1
). Connect the inlet line to the primary pump head on
pump 2.
3. Disconnect the short piece of tubing between the primary and secondary
pump heads on pump 1 (see Figure 4-1
). Connect this tubing to the pump
heads on pump 2.
4. When you finish these connections, go to the next section to continue setting
up the seal wash system.
