Per LN Engineering instructions put into the freezer. When cold, install.
I took measurements during the freezer time:
Initial diameter: 47.00 mm or 1.8500 inches
After 1 hour: 46.99 mm or 1.8495 inches
After 2 hours: 46.97 or 1.8490 inches
After 3 hours: 46.97 or 1.8490 inches
Looks like two hours in the freezer at 0 degrees Fahrenheit is enough time.
