          Spel Coalescer Units Guide Rail System/Lifting, Locating and Locking System
          This facilitates easy insertion and removal of coalescer unit. The system is robust, manufactured
          throughout in stainless steel and is action positive, leaving no doubt the coalescer unit is located properly.
          Brackets fixed to the top and bottom of the coalescer unit simply engage the stainless steel guide rail fixed
          to the top of the stub access shaft.

          The coalescer is then lowered in the normal way, being guided at the correct angle into the conical base
          unit which finally locates the coalescer unit into its final position. Extension guide rails can be incorporated
          into the SPEL extension shafts to suit (preferably when ordered with the separator). However, when the
          separator is full of water, debris or sludge accumulated over a period could prevent the coalescer unit from
          re-seating correctly after servicing. The coalescer unit lifting / locating / locking system ensures the
          coalescer unit is seated correctly and can be locked into position to prevent tampering. The stainless steel
          lifting handle can be extended to suit deep tank inverts and provide easy access for lifting manually or with
          a tripod and hoist utilising the lifting hook.

          2.1.2    SPEL Auto Closure Device (ACD)
          The Automatic Closure Device (ACD) is found in the first chamber of a Puraceptor. The purpose of the
          ACD is to close the separator off automatically when the maximum storage capacity of light liquid is
          attained. The ACD is to ensure that in the event of a major spillage, pollutants do not pass into the
          drainage system; it should not be regarded as a substitute for an automatic alarm / monitoring system.


          Operation and Maintenance
          If the tank should fill with light liquid, the ACD which is calibrated for a specific gravity of 0.85 will
          automatically sink and close off the SPEL Puraceptor. Normally routine maintenance would include
          removing light liquid intercepted within the Puraceptor. If a SPEL automatic alarm/monitoring system is
          incorporated, it will automatically indicate when the Puraceptor should be emptied. Only in an emergency
          will the Puraceptor fill to its maximum and operate the ACD. In such an event the Puraceptor should be
          completely sucked out and the ACD lifted out. To re-insert the ACD, partially fill the Puraceptor with clean
          water (if necessary) to ensure the ACD when re-inserted remains floating and then re-insert the ACD.
          Finally check the ACD is floating and the retaining cap has been replaced to safeguard against its removal
          by unauthorised persons, unless depth of tank precludes doing so from ground level.
