You need to make sure your discharge hose does not freeze. Flexible hoses freeze easiest but even a solid pipe can freeze under some conditions when snow covers the end.
The best solution I seen is to replace the 90 degree fitting after the pipe comes out of the house with a T and a street 45. If the pipe freezes water will shoot out of the T instead of burning out your pump and or flooding the basement. The T will be straight up and down with the 45 attached up top directing the water away from the house.
