If you have any electrical smarts and a little plumbing knowledge, then you should be able to install it.
I recommend connecting the power to the booster pump motor 1st, since you can move the motor around more easily when it's not connected to the PVC pipes. Get a water tight PVC connector, some 1/2" flex conduit and some wire, and a 15 or 20 amp breaker and connect to your service panel. **** You can connect the booster pump to 120v or 240v. Been a while since I installed on, but I think they come from the factory prewired 240v There will be a wiring diagram on the motor and inside installation manual if you want to change it.
Once you have the electrical done, The suction side of the Polaris Booster pump is normally a 1" PVC. Just wrap some teflon tape around a 1" male adapter, and screw it into the booster pump housing. Then connect your suction side & pressure side. (Hopefully your PB label the pipes coming out of the ground at your pool equipment pad.)
