Section 3
Operation
Power To Cool
• After the cabinet is connected to the power source it will
automatically begin operating.
• With the covers and doors closed, the temperature of the
cabinet should reach 36°F to 40°F (2°C to 4°C) in about
one hour.
• Temperature on salad top will maintain 33°F to 41°F (1°C
to 4°C) with pans recessed 2.5” (6.5cm) at 86°F ambient
room temperature for a period of four hours, meeting
NSF-7 requirements.
Temperature Control
• The temperature control on all sald top units is located in
the rear of the unit.
• The factory setting for the control is 37.5°F and maintains
about 34°F(1°C) to 40°F (2°C) inside the box.
• There is also an optional display that can be added to the
front nosing of the unit. The control (without display)
would be mounted on the back of the unitl with a cable
connecting to the display.

or if the power is
shut off.
Efficient Operation
• Cabinets with pans should be operated with pans in
place. Operating the cabinet without all pans in place
may damage the cabinet.
• Continuous opening and closing of the door will hamper
the cabinet’s ability to maintain optimum refrigeration
temperature.
• Top section is not intended for overnight storage. Product
should be removed from pans. Pans can remain in
cabinet while empty.
Defrost
The electronic temperature controller monitors evaporator
temperature and compressor run time to determine the
proper time for a positive defrost cycle. A defrost cycle
can occur as often as every 45 minutes under extremely
heavy usage. When the controller enters the defrost mode
the compressor is shut off and will remain off until the
evaporator coil temperature exceeds 41°F or the controller
reaches a time limit of 50 minutes. The defrost cycle can last
from a minimum of 2 minutes to a maximum of 50 minutes.
Evaporator Fan Operation
Salad and mega top refrigerator units under 60” wide have
one evaporator and one axial fan. 60”, 64” and 72” wide units
have one large evaporator and two axial fans.

During normal operation the evaporator fan may cycle
