3.Vertical check valve models: See Figure 9. Install the o-ring (29) on the check valve body (28) and push the o-ring down, over the 3 guide lands until it is in the o-ring groove of the check valve body (28). Install the check valve spring (27) on the check valve body so that the small coils of the spring slip over the check valve body. Install the assembled check valve body, o-ring, and spring (27, 28 & 29) in the end cover (6) so that the o-ring rests on its seat in the end cover (6) and the spring is visible. Install the perforated plate (26), in the end cover (6) and secure the check valve assembly using the retaining ring (30). Make certain the retaining ring is fully seated in its groove in the end cover (6).
