Hill Phoenix 05DMA manual Refrigeration Piping

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 minimiz- ing the need to unload product. The compres- sor and condensing unit are located on top of the case for easy access.

The diagram below illustrates all of the refrigeration components in the O5DMA. The components surrounded by the box are located in the case tank. Basic definitions of these components are listed on the following page.

If it becomes necessary to penetrate the case bottom for any reason, make certain it is sealed afterward with canned-foam sealant and caulk.
