D431-4097 -National Evaporator Assy. is Obsolete and will be replaced by D431-4023

National Evaporator Assy. is Obsolete and will be replaced by D431-4023.  Works on either style refrigeration system.  For the newer style (small hole) you'll have to remove plate on evaporator and install upside down. See attached pictures for reference.

This is how the evaporator will look after you modify it to fit on a new style, small hole refrigeration unit on a National 431 cold food machine.  You will remove the rivets and flip the bracket.  Drill 2 holes, do NOT use existing holes or you can damage the evaporator, on each end to stabilize it.  See pictures below.  If you need help, please don't hesitate to call us at 800-445-8363.
