i got my membrane from amazon. just pulled out mine to look at the part number so i made sure to order the right one. as for a manual i cant help there. sorry
The V seal on the membrane is to keep the flow from going around the membrane. If you happen to pull it out and don't notice which way it was oriented, it goes on the end that the pressure from the pump comes in.
It's a standard 4x40" membrane, any of those will fit, but more info is needed to get the correct one. Kleen-Rite is almost certainly going to be cheaper than an equipment manufacturer.
