PARTS & SERVICE MANUAL for the DH Series
Display and Hold Cabinets
The DH Series Display & Hold Cabinets are engi-

temperatures ranges, physical wear takes its toll.
When this happens, the information found in this
Manual will prove very helpful. Although the
instructions are easy to follow, all repair proce-
dures should be carried out by a qualified Savory
Certified Service Representative.
