O-Rings
The Sediment Trap end cap o-rings are custom-made. O-rings must be installed properly and kept
in place at all times. Each set includes three custom o-rings (200-0071, 200-0072, 200-0073).
See Chapter 6, ‘Maintenance and Storage’ for detailed instructions on cleaning the o-rings and
positioning the o-rings when inserting the end cap into the controller housing.
Figure 1-7: Sediment Trap O-Ring Installation - Correct Placement is Critical
O-ring maintenance and correct placement is critical to keep the controller
housing end caps from water intrusion. Incorrect o-ring placement results in
cracks or splits that could affect the o-ring seal and cause water damage to the
controller. Water damage from incorrectly placed or maintained o-rings can
void the sampler warranty.
