Temperature Controls

Adjusting the Temperature

• Your new refrigerator is already factory set to run at optimum temperatures for food safety and should require no adjustments.
• Refrigerators are set to cycle between a minimum temperature of 33°F and a maximum temperature of 40°F.
• Adjusting the temperature changes the minimum temperature at which your unit will run. Your unit will not run constantly at this setting. To change it, follow these instructions:

Temperature Controller Operation

NOTE: The temperature controller is located behind the front panel. To access, carefully pop off the front panel. After making temperature adjustments, carefully put the front panel back on the unit.

1. Set temperature:
   • Press SET button; the set temperature is displayed.
   • Press [down arrow] or [up arrow] to modify the displayed value.
   • Press SET button to exit the adjustment and display the unit's current temperature.
2. If no additional buttons are pressed within 10 seconds, the unit's current temperature will be displayed.
3. Lights: Press [light button] button to turn lights 'on' or 'off.'
4. Manual start/stop defrost: Press [defrost button] button and hold for 6 seconds to defrost or stop defrost.

4. Refrigerant LED: When the compressor is running, the LED is on; when the refrigerator temperature is constant, the LED is off. During the delay start, the LED flashes.

5. Defrost LED: During the defrost cycle, the LED is on; when it stops defrosting, the LED is off. During the delayed display of defrost, the LED flashes.

Defrost System

Refrigeration units contain an automatic defrost system. Refrigeration coils are kept below the freezing point (32°F). During compressor downtime, the evaporator fan continues to circulate air through the evaporator coil. This air circulation raises the coil temperature above the freezing point, melting any accumulated frost. Run-off water is drained into the evaporator pan and evaporated.

• If drainage pipe is available, lower the condensation drainage pipe and connect to a drain or condensation pump. Verify the pipe is unobstructed and it is lower than the water receiver indicated by the line on the sticker.
• If no drain is available, the condensation drainage pipe can be hung up. The excess water will be evaporated with the condensate evaporator pan. Note that the use of this option will increase the energy consumption of the unit.
• WARNING: High humidity environments can cause increased amounts of condensation that can overflow the evaporator pan. Connecting the drainage pipe to a nearby drain is necessary for environments exceeding 55% relative humidity.

Loading Product

• Ensure there is at least 4" of clearance from the evaporator.
• Ensure all shelves are sitting level and properly secured before loading products.
• DO NOT store flammable/explosive gas or liquids inside the unit.

Operation

Adjusting the Temperature of the Top Bakery Case Section

• Four perforated baffles come installed on the unit for the unit to operate with a fully refrigerated top section.
• Four solid baffles are included for altering the temperature of the top bakery case section.
• The baffle will prevent (solid) or allow (perforated) refrigerated air from circulating through the display area and returning through the air return grille.
• The top bakery case section of the equipment can be ambient, refrigerated, or 50/50 ambient and refrigerated:

Baffle Configuration for Temperature Control

Perforated Baffles: Allow air to circulate.

Solid Baffles: Block air circulation.

100% Ambient (Non-Refrigerated)

For 100% ambient conditions, two solid baffles must be positioned in each section of the cabinet to block the air flow and the air return grille.

100% Refrigerated

For 100% refrigerated conditions, two perforated baffles must be positioned in each section of the cabinet to allow air to circulate through the display area and return through the air return grille.

50/50 Ambient and Refrigerated

For 50/50 ambient and refrigerated, position two solid baffles in the half of the case intended to be ambient to block airflow. For the half intended to be refrigerated, position two perforated baffles to allow air to enter and return through the air return grille.
