User manual FIRSTLINE 1200A 7

[. . . ] Please make sure you read and understand all the guidelines in the User Manual provided with the vessel. Failure to do so may result in malfunction and potential catastrophic failure. It is recommended that only qualified technicians experienced in servicing hydraulic systems work with this vessel. [. . . ] The locking screws can be unthreaded using an M6 hex wrench. Step 5 Remove the Locking Crescent/Screw Assemblies The locking kit segment/screw assemblies should be easily removed from the retaining groove. Should the assemblies be difficult to remove, it may be necessary to rock the head slightly or tap the head inward with a rubber mallet. Be careful when using metal tools, avoid leveraging against the sidewall of the vessel or scratching the inside surface of the bell area. Step 6 Remove the Head Assembly with One of the Following Techniques FIRST LINE Head Removal Tools - A set of head removal tools is available from FIRST LINE. These head removal tools are expressly designed for the purpose and have proven to be an effective and easy way to remove the vessel head without causing any damage to the vessel. FIRST LINE head removal tools Alternative Head Removal - It is possible to remove the head assembly without the FIRST LINE head removal tools.

If the vessel has been in operation for an extended time, a slight rocking motion or forceful tug may be required to break the head seal bond. Also, a handle at the end of the pipe will ease head removal - forming a T with the pipe that threads into the permeate port. Head Installation Step 1 Install Head - Hold the head assembly, square to the axis of the vessel. Push firmly until the head is correctly positioned and the retaining groove is visible. It may be necessary to use a rubber mallet to tap the head into its engaged position. The thrust cone must be installed with the head at the feed water side of the vessel. * Side with larger outer diameter of thrust ring should be connected with the membrane, side with smaller outer diameter of thrust ring should be connected with the end plate Step 2 Install Locking Kit Segments - Clean and dry the retaining groove. Position the first locking segment so that the end section sits in the retaining groove and the screw aligns with one of the threaded openings in the bearing plate. Conduct a final tightness check of each screw after all three segments are installed. Step 3 Reconnect Permeate Piping - Reconnect the system permeate piping to the permeate port. Step 4 Conduct Pre-Pressurization Inspection - A thorough pre-pressurization inspection should be conducted, including verifying that the heads are properly installed, system piping connections are in place, elements are installed, adapters are installed, and thrust cone is installed at downstream end of the vessel. Step 5 Pressurize System Step 6 Inspect for Leaks - All connections should be free from leaks. Do not operate leaking vessels. Piping and Mounting Recommendations  Use two flexible Victaulic™ connections with an intermediate section of pipe when possible.
