On their site, they dont have the 11 version in 60hz, but they have the NL10MF. So presumably NL11MF?

EDIT: I was looking in the 240v section. In the 115v section they have one called NF11FX.
In the 220-240V versions they use the NL11F, in the 115V versions they use the NF9FX.
The difference in frequency (50Hz vs 60Hz) compensates the difference in displacement.

ppl use to say that is was hard to get these compressor to start with r507, need the exact amount or it wont start, chilly did that.
i always though that r410 was a second stage refrigerant, or a blend was requird to reduce the pressure for single stage.
R410a is used a lot in single stage systems. A lot of airconditioning systems use it. But yes, condensing pressures are higher, and I can imagine that these pressures give that poor R134a compressor a hard time in starting up

If you run into startup troubles, maybe you can try adding a run-capacitor to the system?
