Deleld
Model numbers starting with the letters “SS” have a stainless
steel exterior and interior. Model numbers starting with the letters
“SA” have an aluminum interior and a stainless steel exterior.
Model numbers starting with the letters “SM” have an aluminum
interior and exterior with a stainless steel front and shroud. Door
gaskets are magnetic and mount to the door, snapping in place
and are removable without tools. Keyed door lock is mounted
in the door next to the handle.
Doors can be removed from the cabinet without the use of tools.
Each door has two edge mount, self-closing, cam lift style hinges.
Refrigeration System
All components are mounted to the exterior cabinet ceiling,
outside the food zone and are assembled as one-piece and can be
removed as one-piece. Environmentally friendly R404A refrigerant
is used. The system has the capability of maintaining between
33°F and 40°F (1°C and 4°C) in heavy use food service operations.
Refrigerant is metered using a highly responsive thermostatic
expansion valve. Systems are controlled using Delfield’s ACT
Electronic Temperature Control. It provides improved pull down
times, reducing compressor cycling and longer compressor life
with lower energy consumption. Control system uses adaptive
defrost to assure evaporator coil is free of ice and operating at
optimum efficiency. Evaporator condensate is eliminated using
an energy efficient hot gas system.
Freezer Refrigeration System
All components are mounted to the exterior cabinet ceiling,
outside the food zone and are assembled as one-piece and
can be removed as one-piece. Environmentally friendly R404A
refrigerant is used. The system has the capability of maintaining
between -5°F and 0°F (-21°C and -18°C) in heavy use food service
operations. Refrigerant is metered using a highly responsive
thermostatic expansion valve. System is controlled using
Delfield’s ACT Electronic Temperature Control, which provides
improved pull down times, reducing compressor cycling and
longer compressor life with lower energy consumption. Control
system uses adaptive defrost to assure evaporator coil is free of
ice and operating at optimum efficiency. Evaporator condensate
is eliminated using an energy efficient hot gas system.
Heating System
Heating system cabinets are designed to maintain temperatures
between 120°F and 200°F (49°C and 93°C). Heating elements
are helical shaped, with tubular fins. A circulating fan provides
uniform airflow in the cabinet. The entire heating system is
mounted to the exterior of the cabinet ceiling, outside the food
zone. It is assembled as one piece and can be removed as one
piece. An adjustable electronic thermostat controls temperature.
The system ON/OFF switch is located on the front exterior of
the cabinet.
Service Alert
During normal operation the evaporator fan may cycle
and/or pulse independently of the compressor. Consult
the service manual or contact Technical Support at
1-800-733-8829 if you are unsure of the proper function.
Dual Temperature Refrigeration/Freezer
Each compartment has its own separate refrigeration system.
Condensing units are located on top of the cabinet, outside the food
zone, behind the upper shroud. Evaporator coils are located inside
the cabinet mounted to the interior ceiling of each compartment.
Defrost is automatic. Condensate travels down a tube in the
cabinet sidewall to a receptacle mounted to the exterior bottom of
the cabinet where it evaporates with the aid of an electric heater.
Each compartment’s temperature is individually monitored and
controlled with Delfield's ACT Electronic Temperature Control. Two
exterior digital thermometers monitor temperature. Refrigerator
compartment maintains temperature between 33°F and 41°F (1°C
and 5°C). Freezer compartment maintains temperature between
-5°F and +5°F (-21°C and -15°C). Refrigerant is metered using
a highly responsive thermostatic expansion valve.
Power Switch
Select units are equipped with a power disconnect switch
located next to the energy saver switch and thermostat control
knob. Switch must be in the “on” position for the unit to
operate. On freezers, if the switch is turned off, then returned
to the on position, the unit will enter a defrost cycle and the
display will read “Def.”
