2. Unscrew the sight glass assembly where the elbow fitting joins the strainer/filter.

3. Remove used filter assembly, and replace with new assembly.

4. Inspect and clean the orifice inside the sight glass blocks. The orifice must be removed with an Allen wrench.

5. Coat/lubricate the O-rings with silicone grease.

6. Reattach the connectors to the sight glass/orifice blocks.;
