*For temperature pressure controlled cases, cutout pressure must produce listed evaporator temperature. Differential should preserve product integrity while preventing
compressor short cycling. **For temperature pressure termination, set termination control to terminate defrost when evaporator temperature reaches 48 degrees F
except when othewise listed. Use for non-critical temperature cases only. NOTE : Reverse air defrost is not recommended for any Impact Merchandiser except M1LGE.
