• Easy to Service & Load: Removable shelves and columns mean a route driver can swap out an empty shelf for a pre-loaded one in minutes, or quickly clear a jam without a major disassembly.

• Strong Security: Built with sturdy locks and durable materials to protect your cash and inventory from theft and vandalism.

• Established Parts & Service Network: As a Crane/National machine, there is a vast network of distributors and technicians familiar with the model, ensuring support is never far away.

4. Benefits for Location Hosts & Consumers

A well-placed National 168 provides significant value to the location where it’s installed and the end-users who purchase from it.

• Convenience: Offers both snacks and cold drinks in a single, compact footprint, saving valuable floor space.

• Increased Employee/Visitor Satisfaction: Provides quick access to refreshments, improving morale and keeping people on-site.

5. Machine Setup & Programming

Proper setup is crucial for smooth operation. Here’s a step-by-step overview:

1. Placement & Leveling:

• Place the machine on a solid, level floor near a dedicated 115V outlet.

• Use a level on the top of the cabinet and adjust the front leveling legs until the machine is perfectly plumb. An unlevel machine can cause products to vend incorrectly or get stuck.

2. Powering Up & Initialization:

• Plug the machine in. The control board will typically go through a initialization sequence.

• Allow the refrigeration system 4-6 hours to reach proper temperature before fully loading drinks.

3. Programming Basics (Using the Keypad Inside the Service Door):

• Accessing Programming Mode: Unlock the service door. The programming keypad is usually located near the control board.

• Setting Prices: Navigate to the price setting menu. You can set a single default price or use dual-pricing to set separate prices for snacks and drinks. Prices are usually set per selection (column/shelf number).

• Setting Dates & Times: Essential for tracking sales data.

• Configuring Cashless Pay (if equipped): This typically requires connecting to a management portal via Ethernet or cellular connection to activate the card reader.

• Consult the official Crane National 168 manual for specific programming codes and sequences, as they can vary by control board version.

4. Loading for the First Time:

• Snacks: Load each spiral, ensuring the product is seated firmly against the rear of the shelf. Set the correct spiral size (adjustable on most models) to match your product.

• Drinks: Load cans or bottles into each column, ensuring they stack neatly. Adjust the depth sensor if necessary for different package sizes.

6. Loading, Servicing & Maintenance

Routine care prevents most common issues.

Daily/Weekly (Operator Route):

• Collect cash and data (via DEX or handheld).

• Restock low or empty selections.

• Wipe down the exterior and glass.

• Check the delivery bin for any stuck product.

Monthly/Quarterly:

• Clean Condenser Coils: Located behind the lower front grill or at the back. Use a coil brush or compressed air to remove dust and lint. This is the #1 maintenance task to ensure efficient cooling and prevent compressor failure.

• Inspect Spirals and Motors: Look for worn or cracked spirals. Listen for noisy or struggling motors.

• Clean the Delivery Bin and Chute Area.

• Test Payment Systems: Ensure the bill validator is accepting and rejecting bills properly, and the coin mech is providing accurate change.::::Crane National 168

Troubleshooting Common Issues:

• Product Won’t Vend: Check for jams, ensure the spiral is turning, verify the motor is connected, and confirm the product is not too large or stuck.

• Machine Takes Money But Doesn’t Vend: Often a motor or sensor issue. Check if the selected motor is trying to run. The “motor drive” or “sold out” LED on the control board can help diagnose.

• Drinks Not Cold: Clean condenser coils. Check if the evaporator fan inside the cooler is running. Listen for the compressor operation.

• Payment System Errors: Clean bill validator with a specialized cleaning card. Check for jammed coins. Reboot the machine.

7. Advanced Management & Technology Integration

Modernizing a National 168 can significantly boost its performance and profitability.

• DEX (Data Exchange) Compliance: The machine can send detailed sales data (item-level sales, out-of-stock events, cash totals) to a handheld route device or directly to vending management software (VMS) via a DEX cable. This enables pre-kitting (preparing restock items in advance), dynamic routing, and precise sales analysis.::Crane National 168

• Cashless Vending Kits: Adding a card reader from companies like Cantaloupe, USA Technologies, or Ingenico is a straightforward upgrade. It opens up sales to customers without cash, increases average transaction value, and provides real-time sales and inventory data.

• Telemetry & Remote Monitoring: With a cashless kit or a separate modem, operators can monitor machine health (temperature, door status, power outages), track sales in real-time, and receive alerts for jams or outages, enabling proactive service.

• Energy Management Devices: Adding a device like the eSight can put the machine on an optimal energy-saving schedule, cycling lights and cooling during closed hours to cut electricity costs by 30% or more.:::Crane National 168

8. Pricing, ROI, and Where to Buy

• Pricing: Costs vary based on condition, age, and features.

  • New/Refurbished from Distributor: Typically between $4,500 and $7,500.

  • Quality Used/Reconditioned: A popular option, ranging from $2,000 to $4,500.

  • “As-Is” Used: Can be found for less than $2,000, but may require significant repair investment.

• ROI Considerations: A well-placed National 168 can generate $200-$500+ per week in sales. Factoring in product cost (approx. 40%), commission (15-25%), and expenses, a machine often pays for itself in 12-24 months, generating profit for many years thereafter.::Crane National 168
