Hi Kevin ...
2 things going against you here...
1 . PFC caps are hooked up in parallel with the 120V in
2. you need motor run caps ( electrolytics wont work with AC too long
they go BANG !! )
the motor run caps are normally 6" tall 3" wide and 1-2" thick oval shaped
in an aluminum case
try to find a couple that are rated for 240V 30 or so uF.
