Loss of sanitary approvals
Loss of sanitary approvals can result from improper installation/mounting.
• Take special care when installing in hygienic or sanitary applications. Comply with
installation/mounting guidelines to ensure cleanliness and the ability to keep the wetted
parts in a position to be readily cleanable. (See relevant EHEDG/3A documentation - not
supplied).
Loss of sanitary approvals
• For 3-A Sanitary Approved device installation where the customer tank process
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.
For Hygienic encapsulated antenna, the lens acts as a gasket/seal and should be used in
conjunction with a cleanable seal as required by the specific process connections (for
example, DIN 11864-3).
