McCall MCCR1-G - Manual (Page 5)


McCall
McCall reach-in models 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 27°F and 41°F (3°C and 5°C) in heavy use food service
operations. Refrigerant is metered using a highly responsive
thermostatic expansion valve. Systems are controlled using an
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 an
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.
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 removable 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. Two exterior Thermometer,
Digitals 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.
