Usage Features
Installation:
- Good Air Circulation: Requires at least 5 inches of clear space from the rear of the unit to the wall to ensure proper airflow and prevent obstruction.
- Strong Ground: Must be placed on a floor strong enough to support the total weight of the cabinet and its contents.
- Avoid Heat Sources: Should not be placed near hot corners, stoves, or in direct sunlight, as high ambient temperatures reduce cooling efficiency.
- Indoor Use Only: Designed for indoor installation to prevent exposure to rain.
- Stabilizing and Leveling: The unit must be installed in a stable, level condition with the front wheels locked.
- Dedicated Outlet: Each unit requires a dedicated electrical outlet.
- Condensate Pan: A black plastic condensate pan must be placed through the back or front, ensuring pads are installed upwards and a drain hose is in the pan.
Basic Operation (Refrigerators - TSR-23SD*, TSR-49SD, TSR-72SD):
- Power On: Plug in and turn on the power switch located on the bottom of the top grille (right side). The display panel will light up, emit a beep, and the compressor will start.
- Default Temperature: The default temperature setting is "5".
- Automatic Cycling: The compressor is automatically controlled by an electronic controller (PCB, D-Sensor).
- Automatic Defrost: The defrost cycle is automatically controlled by the R-sensor and the PCB.
- Temperature Setting: Users can adjust the temperature level from "1" (higher temperature) to "9" (lower temperature).
- Interior Light: Activated by a rocker switch at the bottom of the grille when the door is opened.
- Evaporator Fan: Runs only after all doors are completely closed.
Refrigerator Display Panel Features:
- Inner Temperature Display: Shows the inside temperature, with a range of 14°F to 69°F (-10°C to +20°C). Displays "LO" for temperatures below 14°F and "HI" for temperatures above 69°F.
- Fan Running Indicator: Illuminates when the fan motor is running. The evaporator fan motor activates when the door (or all doors for multi-door models) is closed.
- Door Opening Indicator: Illuminates when any door is open.
- A warning beep sounds three times if a door is open for approximately 30 seconds.
- The beep sounds five times if a door is open for approximately 1 minute.
- The beep sounds continuously if a door is open for approximately 5 minutes.
- The beep stops immediately when the door is properly closed.
- Turbo Cooling:
- Activated by pushing the T.C. (Turbo Cooling) button. The compressor runs continuously until the D-Sensor detects 14°F (-10°C) to quickly lower the temperature (maximum compressor run time is 120 minutes).
- Pushing the T.C. button again during Turbo Cooling mode returns the compressor to normal operation.
- The Up/Down temperature buttons do not affect compressor operation during Turbo Cooling mode.
- Up/Down Button (Temperature Control): Allows setting the inside temperature level from "1" to "9". Pushing the Down button lights higher level numbers for lower temperatures.
Basic Operation (Freezers - TSF-23SD, TSF-49SD, TSF-72SD):
- Power On: Similar to refrigerators, plug in and turn on the power switch. The display panel will light up, beep, and the compressor will start.
- Default Temperature: The default temperature setting is "5".
- Automatic Cycling: The compressor is automatically controlled by an electronic controller (PCB, F-Sensor).
- Automatic Defrost: The defrost cycle is automatically controlled by the D-sensor and the PCB.
- Temperature Setting: Users can adjust the temperature level from "1" (higher temperature) to "9" (lower temperature).
- Interior Light: Activated by a rocker switch at the bottom of the grille when the door is opened.
- Evaporator Fan: Runs only after all doors are completely closed.
- Good Air Flow: Critical for freezer units. Products should not press against the back wall or be within four inches of the evaporator compartment.
Freezer Display Panel Features:
- Inner Temperature Display: Shows the inside temperature, with a range of -50°F to 50°F (-45°C to +10°C). Displays "LO" for temperatures below -50°F and "HI" for temperatures above +50°F.
- Fan Running Indicator: Illuminates when the fan motor is running. The evaporator fan motor activates when the door (or all doors for multi-door models) is closed.
- Door Opening Indicator: Similar to refrigerators, it illuminates when any door is open and provides audible warnings for prolonged open doors (3 beeps at 30 seconds, 5 beeps at 1 minute, continuous beeping at 5 minutes).
- Manual Defrost:
- Initiated by pushing the MANUAL DEFROST button for 5 seconds.
- During manual defrost, the Up/Down temperature buttons cannot cycle the compressor ON or OFF.
- To return to normal mode from manual defrost, push the MANUAL DEFROST button for 5 seconds again.
- Up/Down Button (Temperature Control): Allows setting the inside temperature level from "1" to "9". Pushing the Down button lights higher level numbers for lower temperatures.
Defrost (Freezers):
- Automatic Defrost Cycle: The electronic defrost controller is factory-set to provide a defrost cycle every 6 hours (4 times per day).
- Adjustable Intervals: Defrost intervals can be changed by adjusting a switch located inside the top grille if unusual operating conditions require it.
- Defrost Termination: Once frost is eliminated, the temperature rises to 60°F (15°C). When sensed by the defrost limit control, the unit switches back to refrigeration mode.
- Display during Defrost: The panel displays "dF" during the defrost cycle.
Maintenance Features
Cleaning:
- Interior and Exterior: Can be cleaned with warm water and soap. Abrasive cleaners should not be used to avoid scratching the stainless steel surface.
- Condenser Fins: Must be kept free of dust, dirt, and grease for proper refrigeration performance. Periodic cleaning is required, at least every three months (90 days) or as needed.
- Gasket: The door gasket should be cleaned frequently to maintain proper sealing.
- Post-Cleaning Check: After cleaning, verify the unit's safety and proper operation.
Power Cord:
- Ensure the power cord is connected to the proper voltage.
- A protected circuit with correct voltage and amperage is required.
- Turn off the power switch before disconnecting the power cord for maintenance or cleaning.
