Illustration 1	g06029383

Measure the distance from the back of the lifting eye to front of the existing differential pressure sensor bracket. Refer to Illustration 1.
- If the distance is less than 18.5 mm (0.73 inch), 383-0205 Washers (1) are required
- If the distance is greater than 18.5 mm (0.73 inch), do NOT use washers (item 5).
