Plumb the instrument
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current material safety data
sheets (MSDS) for safety protocols.
Refer to
Figure 6
and the steps in this procedure to plumb the instrument.
User-supplied items:
• Wrench, 7/16-in.
• Isolation valve
• Tubing, ¼-in. OD polypropylene, PFA or 316 stainless steel for inlet and outlet
1. Install the isolation valve on the process pipe. Open and close the isolation valve several times to
let water into the system to remove debris.
2. Push the tube from the isolation valve into the WATER IN port until it stops. Do not crimp or bend
the tubing.
3. Tighten the compression nut on the WATER IN port by hand. Make a mark on the compression
nut and tube for reference.
Note: For the dual stream model, do step 2 and 3 for the second WATER IN port.
4. Tighten the compression nut another 1¼ turns.
5. Push one end of a 10-ft tube into the WATER OUT port until it stops. Do not crimp or bend the
tubing.
6. Tighten the compression nut on the water outlet side by hand. Make a mark on the compression
nut and tube for reference.
