• Do not store explosive substances such as aerosol cans with a flammable propellant in this appliance.
• Ensure the appliance is placed on a level, stable surface to prevent tipping.
• Maintain adequate clearance around the unit for proper ventilation and heat dissipation.
• Do not use electrical appliances inside the food storage compartments of the appliance, unless they are of the type recommended by the manufacturer.

Setup and Installation

1. Unpacking: Carefully remove all packaging materials, including protective film and tape. Inspect the unit for any shipping damage. Report any damage immediately to the carrier.
2. Placement: Position the refrigerator on a strong, level floor capable of supporting its weight (approximately 430 lbs empty, plus contents). Ensure there is sufficient space for air circulation around the unit, especially at the rear and sides, to allow the condenser to operate efficiently. The unit is equipped with four 2 1/2" casters for easy positioning. Once in place, ensure the casters are locked to prevent movement.
3. Electrical Connection: Connect the unit to a dedicated, properly grounded electrical outlet. Refer to the specifications section for electrical requirements. Do not use extension cords or adapter plugs.
4. Initial Cleaning: Before first use, clean the interior and exterior surfaces with a mild detergent and warm water. Rinse thoroughly and dry completely.
5. Initial Startup: After positioning and connecting power, allow the unit to run empty for at least 2-4 hours to reach its operating temperature before loading products.

Operating Instructions

Your Kool-It KSM-42 merchandiser is designed for user-friendly operation.

• Power On/Off: The unit powers on automatically when plugged into a live outlet. To turn off, disconnect from the power source.
• Temperature Control: The refrigerator features a digital temperature readout display and electronic thermostatic control. The optimal temperature range for preservation of foods and beverages is 33-40°F (approximately 0.5-4.4°C). Adjust the temperature using the controls on the digital display as needed.
• Loading Products: Utilize the heavy-duty polyethylene coated adjustable wire shelves to organize products efficiently. Ensure that products do not block the internal air circulation vents to maintain consistent temperatures throughout the cabinet. The positive air flow system ensures even cooling.
• Door Operation: The double-pane locking glass doors are ergonomically designed and self-closing. Ensure doors close completely after each use to maintain temperature and energy efficiency.
• Interior Lighting: The LED interior lighting provides total product display. This lighting typically operates when the unit is powered on.

Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your refrigerator.

• Regular Cleaning:
  • Interior: Clean the interior surfaces, shelves, and floor regularly with a mild, non-abrasive cleaner and warm water. Rinse and dry thoroughly to prevent odors and maintain hygiene.
  • Exterior: Wipe down the black exterior baked enamel steel finish with a soft cloth and mild cleaner. Avoid abrasive cleaners that can damage the finish.
• Condenser Coil Cleaning: The condenser coils, located at the bottom rear of the unit, should be cleaned every 1-3 months, depending on the operating environment. Dust and debris on the coils reduce efficiency and can lead to compressor failure. Use a brush or vacuum cleaner to remove accumulated dirt. Always disconnect power before cleaning the condenser.
• Gasket Inspection: Inspect the one-piece magnetic door gaskets regularly for cracks, tears, or signs of wear. Damaged gaskets compromise the seal, leading to energy loss and inefficient cooling. Replace worn gaskets promptly.
• Automatic Defrost System: This unit features an automatic defrost system. While manual defrosting is not required, ensure the drain pan is clear and free of obstructions.
