6.2.2 Reconnect a tube fitting<br />
You can disconnect and reconnect a tube fitting many times and still obtain a correct<br />
leak-proof seal. Refer to Figure 6-2 detail A which shows a tube fitting after you have<br />
disconnected it. Use the following procedure to reconnect it:<br />
1. Refer to detail B. Insert the tube (5) with the swaged ferrules (2, 3) into the tube fitting (1),<br />
until the front ferrule (2) is fully in the body of the fitting.<br />
2. Refer to detail C. Tighten the nut (4) by hand.<br />
3. Use a wrench or spanner to turn the nut (4) to its original position (you will feel an increase in<br />
resistance when the nut is in its original position), then tighten the nut slightly.<br />
6.3 Maintenance frequency<br />
The iH system requires little user maintenance. The maintenance operations you can carry<br />
out are described in the following sections. The frequency of maintenance operations<br />
depends on your process. Adjust the frequency of maintenance operations according to your<br />
experience.<br />
When you maintain the iH system, use BOC <strong>Edwards</strong> maintenance and service kits. These<br />
contain all of the necessary seals and other components necessary to complete maintenance<br />
operations successfully.<br />
