Safety Instructions
Always follow basic safety precautions when using electrical appliances to reduce the risk of fire, electrical shock, or injury.
- Electrical Safety: Ensure the unit is connected to a properly grounded 115V/60Hz/1-ph power supply with a dedicated circuit. Do not use extension cords.
- Placement: Position the unit on a level, stable surface. Allow adequate clearance around the unit for proper ventilation (minimum 6 inches from walls).
- Handling: The unit is heavy (357 lbs). Use appropriate lifting equipment and personnel when moving or installing.
- Cleaning: Disconnect power before cleaning. Use mild, non-abrasive cleaners.
- Maintenance: Only qualified service personnel should perform repairs.
- Ventilation: Do not block air vents or condenser coils.
- Food Safety: Maintain proper temperatures to ensure food safety.
Setup
- Unpacking: Carefully remove all packaging materials. Inspect the unit for any shipping damage. Report any damage to the carrier immediately.
- Caster Installation: The unit comes with (4) 6-inch casters (2 locking and 2 non-locking). Attach the casters to the bottom of the unit, ensuring the locking casters are positioned at the front for stability.
- Placement: Move the unit to its desired location. Ensure the floor is level and strong enough to support the unit's weight. Maintain at least 6 inches of clearance from walls and other equipment for proper airflow.
- Power Connection: Plug the unit into a dedicated 115V/60Hz/1-ph electrical outlet. The unit requires a NEMA 5-15P plug.
- Cutting Board & Food Pans: Place the 3/4-inch thick removable polyethylene cutting board on the top prep area. Insert the (12) 1/6 pans into the designated slots.
- Initial Startup: Allow the unit to sit for at least 2 hours after moving before plugging it in to allow refrigerants to settle.
Operating Instructions
Digital Temperature Controller
The unit is equipped with a precise digital temperature controller with an LED display for easy monitoring and adjustment.
- Power On/Off: Press the power button (usually marked with a circle and vertical line) to turn the unit on or off.
- Temperature Display: The LED display shows the current internal temperature.
- Setting Temperature: Refer to the controller's specific instructions (often a "SET" button) to adjust the desired temperature. Allow several hours for the unit to reach the set temperature after initial startup or adjustment.
- Automatic Defrosting: The unit features automatic defrosting, which periodically clears ice buildup from the evaporator coil. During defrost cycles, the temperature display may temporarily rise.
Food Preparation Area
- Insulated Hinged Lid: Keep the insulated hinged lid closed when not actively preparing food to maintain optimal temperatures in the food pans and conserve energy.
- Food Pans: Utilize the provided 1/6 pans for ingredients. Ensure pans are properly seated to allow for efficient cooling.
- Cutting Board: The removable polyethylene cutting board provides a convenient and sanitary surface for food preparation.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your prep table.
- Daily Cleaning:
- Wipe down all stainless steel surfaces with a soft cloth and mild, non-abrasive cleaner.
- Clean the removable polyethylene cutting board thoroughly after each use.
- Clean the interior of the cabinet and shelves with a mild soap and water solution.
- Door Gasket Maintenance: Regularly inspect door gaskets for tears or damage. Clean gaskets with warm, soapy water to maintain a tight seal. Replace damaged gaskets promptly.
- Condenser Coil Cleaning (Monthly/Quarterly):
The condenser coil, located at the rear, can accumulate dust and debris, reducing efficiency. Disconnect power before cleaning. Use a stiff brush or vacuum cleaner to remove dirt from the coil fins. For stubborn buildup, professional cleaning may be required.
- Drain Pan: Periodically check and clean the drain pan to prevent blockages and odors.
