View Port Maintenance

  1. Cleaning or replacing of glass can be done while the equipment is in operation.
  2. To clean the interior of the glass, the frame (10) must be removed from the body (14) of the rectangular view port.
  3. Once this is done, the rectangular view port is no longer considered pressure-tight.
  4. We recommend following the Sub-Assembly Instructions procedure for both #1 and #2 Sub-Assemblies (as shown above) before the equipment is put back in to operation.
