To get the coefficient of determination you need to be in STAT mode (press MODE and choose 1 for stat) and then choose 1 for line (it only works for linear data). Type in your coordinate points (type in the x value then press the button next to ENT that says (x,y) and then type in your y value and press ENT. Your screen should then say DATA SET = 1.00.
Enter a few more coordinates.
Then to get your coefficient of determination press ALPHA (the blue green button under 2nd F) and press the ( button (above it in blue you will see r). Press = and there is your coefficient of determination.

This is a tough question because it is hard to find this info on the web and a different port is used for DE filters and sand filters. On sand filters the top port of the filter is the inlet while on DE filters the bottom port is the inlet. With the valve not connected to the DE filter and in the FILTER position determine which port allows water to flow to the bottom outlet of the filter. This can be easily determined by running water from a hose into the bottom port and whichever is the pump port will have water coming out of it. A similar test can be done for the other ports. I hope this helps.
