2. Plumbing the Workstation pump Inlets.
a. Workstation pump inlets, attach two fittings to 1/8” (3.2 mm) OD
PTFE tubing as described
earlier. (See Section 4.1, General Guidelines for Creating Your Own Tubing.)
To connect the SV5-4 buffer select valve or the SVT3-2 valve before the pump inlet, 1/8” (3.2
mm) OD
PTFE tubing is used.
b. Screw the tubing into the inlet connectors on the bottom of the Workstation pump housing.
Ensure a firm connection but do not over-tighten.
c. Place opposite end of tubing in solution bottles A and B. Refer to figure 4-1. If an SV5-4 valve is
in use, attach the pump inlet tube to its common port. Refer to section 2.6.3.
Figure 4-5. Plumbing Connections to the Workstation Pump
3. Plumbing from the Workstation pumpheads to the Transducer (Figure 4-3).
a. Use the two pieces of tubing labeled PUMP from the tubing kit or make two fittings using 1/16”
(1.6 mm) OD orange PEEK tubing and 1/4-28 fittings, as described in section 4.1.
b. Connect the tubing to each pumphead outlet port and to each transducer inlet port. Ensure a
firm connection but do not over-tighten.
4. Plumbing from the Transducer to the Mixer (Figures 4-2 and 4-3).
a. Use the tubing labeled #1 from the tubing kit or make a fitting using 1/16” (1.6 mm) OD orange
PEEK tubing and 1/4-28 fittings.
b. Connect the tubing to the transducer outlet port and to either of the inlet ports on the mixer. Plug
the unused mixer inlet port using the plug provided for this purpose. Ensure a firm connection
but do not over-tighten.
5. Plumbing from the Mixer to the AVR7-3 Inject Valve.
a. Use the tubing labeled #2 from the tubing kit or cut a suitable length of 1/16” (1.6 mm) OD
orange PEEK tubing that will reach from the mixer outlet port to port 5 of the inject valve. Attach
1/4-28 fittings to each end.
b. Connect the tubing to the mixer outlet port and to port 5 on the inject valve. Ensure a firm
connection but do not over-tighten.
