How do I build the new pipe system?

The heat pump is on the way. I also ordered a new pentair multiport and a pentair rainbow chlorine feeder. Now all I have to do is put it all together. Any tips, tricks or, even more important, any "don't do this" stories would be appreciated. The only special consideration I have is I have limited space to install the heat pump. My filter is alongside my house and there is a chimney that is also in the way.

That is kinda they way it is. The dotted line is the house, the ch is the chimney. Pipes is where the pipes are. I am going to have to have a 90 degree turn from the filter to the pump and another 90 degree turn from the pump to the feeder and return to pool pipe. I was thinking of using the flexable pipe to reduce the sharpness of the turns. Any thoughts on this?
Thank you.

_Please note- the position of the heat pump is directly opposite the filter. The BB moves the word pump to the margin when it displays the post.

you can get long sweep 90 bends, they don't really have a sharp angle, they are more rounded and should work well.

sevver, you're not referring to the drain-waste-vent PVC swept 90's are you? If so they aren't schedule-40 and won't handle the pressure.

I would use 2 45 degree bends to make up the 90 degree turns. Make sure you buy the fittings that have the deep sockets so the pipe has plenty of area for the bond to occur. Another thing to keep in mind is make sure you plumb in some type of drain fitting in any runs where water would sit when the pump is off. This will help when winterizing.
