I purchased a glider that came with a PZL Vario (WRs-5D). All of
the instruments had been removed from the panel. I do have all the
components for this system, but I am looking to see if anyone has
a manual on how to correctly set this up.

It's a bog-standard vario. "S" is the static or total energy
connection, "W" is the capacity. It's a bit slower to react than a
Winter vario, but averages quite nicely as a result.
