Tubing connects to the 1/4" inlet (WATER IN) and outlet (WATER OUT) 316 stainless
steel compression fittings on the analyzer. See
wrench.
Figure 7 PAT700 water inlet and outlet connections
To connect plumbing to the 1/4" inlet (WATER IN) port, follow these steps:
1. To avoid introducing debris through the inlet plumbing, flush the isolation valve by
opening and closing it fully several times.
2. Without crimping or damaging the tubing, push one end of the inlet tubing into the
water inlet until it cannot be inserted any farther.
3. Without pulling on the tubing, hand-tighten the compression nut.
4. Mark the compression nut and the WATER IN connector as references for tightening
the nut.
5. Tighten the compression nut 1-1/4 turns to secure the connection.
CAUTION
Over tightening the compression nut can damage the ferrules, causing leaks that
can result in measurement error or property damage. After tightening the
compression nut 1-1/4 turns, do not tighten it more than another 1/4 turn to seal
the connection.
To connect plumbing to the 1/4" outlet (WATER OUT) port, follow these steps:
1. Attach the 10-foot long, 1/4" OD polypropylene drain tubing to the WATER OUT port
of the analyzer.
2. Taking care not to crimp or damage the tubing, push one end of the tubing into the
water outlet port until it cannot be inserted any farther.
3. Taking care not to pull on the tubing, hand-tighten the compression nut.
4. Mark both the compression nut and the WATER OUT connector as a reference for
tightening the nut.
5. Tighten the compression nut 1-1/4 turns to secure the connection.
6. Leak test the connections by slowly opening the upstream isolation valve to introduce
water into the analyzer. Pulse the valve several times by opening and closing it, then
recheck the fittings.
7. If necessary, slowly tighten the compression fittings to stop any leaks.
