Note: The Delfield Blast Chiller/Shock Freezer is wired independently of the remote
condensing unit. No interconnecting wiring is required between the blast chiller
and the condensing unit. All condensing units have units have crankcase heaters.
Condensing unit control systems are provided wired from the factory. Field
Connection is made by connecting supply power to the compressor contactor.
Outdoor condensing unit applications require the use of an optional UL listed hood,
delfield P/N CUHOOD, for protection from the elements. Water cooled units are not
recommended for outdoor installation.
Interconnecting piping, curbs or other mounting methods and refrigerant are not
included. Installation must be made by a qualified refrigeration technician. Piping runs
of greater than 100 feet require consultaion with the factory.
