connection exists, a leak detection port of minimum 2.4 mm diameter must be provided
at the lowest point in the process connection where leakage can occur.

If leakage is detected at any time while the device is installed, then the device process
connection parts must be disassembled and thoroughly cleaned prior to gasket
replacement and reassembly.
