Plumbing set-up:
1) (#1) Durso drain pipe assembly. Unscrew the fastener nut from the bottom of the bulk-head fitting. Make sure the rubber gasket is in
place against the Flange of the bulk-head fitting. Slide the entire Durso drain pipe from the top of the aquarium and through the larger
drain hole of the tank.
2) (#2, #3) Return line and directional return nozzle. Unscrew the directional return nozzle (#3). Then just like step 1 of the Durso drain
pipe, Unscrew the fastener nut from the bottom of the bulk-head fitting. Make sure the rubber gasket is in place against the Flange of
the bulk-head fitting. Slide the entire return line from the top of the aquarium and through the smaller return hole of the tank. Once the
return line is in place, hold the return elbow against the smaller hole of the overflow box wall. Take the #3 directional return nozzle and
screw through the hole and into the return elbow (only hand tight is enough).
3) With both of the fittings in place. Open the cabinet and go under to screw in the fastener nuts onto the bulk head fittings from below.
Tighten as much as possible by hand and then use a Channel lock pliers to tighten another half of a turn (Avoid over tightening).
4) You may wish to glue the PVC pipe and tube into the fitting or you can also apply some Teflon tape on the edges and push into the
fitting.
5) Connect the return tube onto the pump outlet fitting. This will finish the return line from bottom to top.
6) Drain line's soft tubing now should go directly into the filter sock if you have added one. This will finish the drain line from bottom to
top.
