REFRIGERATION PIPING
The expansion valve and other controls are located on the
left-hand side of the case and are accessible without lifting
the fan plenum.
The controls cluster may be reached by lifting only the left
hand deck pan minimizing the need to unload product. The
compressor and condensing unit are located on top of the
case for easy access.
