    Important: Suction screens are intended to be installed in the suction hose after a major compressor failure.

  1. Using a caliper that reads to 3 decimal places, measure the ID of the suction hose or manifold suction fitting. Refer to the suction screen coverage chart above to determine the correct size screen for the application.

  2. Object Number: 812269  Size: SH
  3. Select and install the correct mandrel (1) on the threaded portion of the installation tool bolt.
  4. • The brass Universal Mandrel is for use on hose fittings with a smooth bore where the screen installs flush with the end of the fitting.
    • The 0.471 in (11.96 mm) Mandrel is only for the 0.471 in (11.96 mm) screen in hose fittings with an internal hourglass shape where the screen installs at the recessed, reduced diameter point.
