NOTE
Always read and understand the instructions. Never remove any piping component without verifying that the system is depressurized and drained.
Refer to Technical Data Sheet TFP1860 for more information.
Pipe Preparation
Step 1. Verify hole size from the table below.
Step 2. Hole must be drilled on the pipe centerline. For crosses, ensure double outlet holes are aligned.
Step 3. Remove any sharp or rough edges from the hole or upper housing contact area. The gasket-seating surface on the pipe should be examined to verify all loose debris, dirt, chips, paint and any other foreign material such as grease are removed.

a. Proper hole preparation is required for effective sealing and performance. Check the pipe seal sur- face within 5/8” of the hole to be certain it is free from conditions which would affect proper gasket sealing. Remove any sharp or rough edges from the hole or upper housing contact area that might affect assembly, proper seating of the locating collar or flow from the outlet. Check gasket grade to be certain it is suitable for the service. For crosses, ensure double outlet holes are aligned on op- posite sides of the pipe. The use of threaded products other than steel pipe, such as dry pendants, etc. may not be compatible with the female threaded outlet on the Mechanical Tee. Always confirm compatibility by contacting Tyco Fire Protection Products.
