Well, I'm having the darndest time getting my camera to talk to the computer; have also tried emailing cell phone photos to myself without luck so far. Anyway, I still plan to post some pictures when I figure out those issues.
As for setup, given the lack of instructions that come with the package, I thought it might be useful to describe how I hooked things up, and what my reasoning was. The box came with two plastic bags of parts for connecting hoses -- two barbed fittings (threaded on one end, barbed on the other), two smooth hose connection fittings (threaded on one end, and more or less smooth on the other), two hose clamps, and four wire clamps (not sure what the technical name for these clamps is). I decided that the barbed fittings are best used with the transparent (with reinforcing web inside) piece of tubing that is provided to go from pump to filter, since that tube feels more 'stretchy' and flexible than the two ribbed hoses provided to connect the system to the pool. One of the barbed fittings I received was an L -- I put this on the filter side of the tubing, since there was no way it could thread into the port on the pump side of the tube (the end of the L would have hit the pump while trying to tighten it). I used the hose clamps on the pump/filter tubing; I think they make a better seal than the other type of clamp, and they were in the plastic bag with the barbed fittings (so perhaps it was Hayward's intention to use those clamps with those fittings).
I used the two smoother plastic fittings, and the wire-type clamps, with the hoses from pool to pump, and from filter back to pool. On the pressure side, I double clamped the hose at both ends (using hose clamps I already had in hand from the previous pump setup), since I had read various stories about hoses popping off.
I used 3-4 wraps of teflon tape on the fittings before threading them in (probably more than what was provided on the tiny little roll of tape provided with the system; I'm not sure, since I didn't use that tape). I did end up with a leak on the pressure side, at the pump fitting connected to the tubing running up to the filter. That wasn't too surprising, as that fitting screwed in more easily than the others, and bottomed out before I felt enough drag from the tape. Next spring, when I set this up for the long run, I will use more tape, or possibly the paste compound. There is also a slight suction side leak, where the ribbed hose is clamped onto the existing intake fitting on the pool. It works fine during normal operation (just a few tiny bubbles visible, whizzing through the water in the pump basket). However, when I experimented with vacuuming, a lot of air quickly got into the basket from the leak, so I discontinued that. Again, this is something to fix next spring.
After running the system for a about 8 hours a day, on two successive days, the gauge read 14 psi (it started at ~12.5 psi). I backwashed, watching sight glass, then rinsed, and it came back down to the original 12+. Kind of fun that this all works like it is supposed to (sand filters are a new thing to me).
Next spring I may also consider hard-plumbing part of the setup. For now, though, I am happy with how it works, and am now waiting for a nice sunny day to drain the pool and pack things up.
I will still post pictures, but wanted to give a few details that might be useful to other new owners of this system.
