4. Take the tee assembly off of the primary discharge pipe. Do Not unscrew any of the Teflon taped fittings.

5. Clean all the PVC pipe ends with the PVC cleaner.

Hazardous fumes

Follow the cement and cleaner manufacturer’s instructions. Use the PVC

cement in a well ventilated area away from fire or flames.

6. Glue the PVC fittings where indicated by the pencil marks. Wait 10 minutes for the glue to cure.

Final Assembly:
