1. Insert the inlet pipe and the inlet/outlet assembly into the remaining hole on the left hand side of the Marine-Pac 3 (when viewed with the lighting arm pointing towards you, as shown in Figure 16.)
2. If the tube is hard to fit, dip the end of the return hose in a cup of boiling water to soften it and fit it over the hose barb on the inlet/outlet.
3. Attach the inlet/outlet assembly to the neck of the tank using the hook on the side of inlet/outlet assembly.
