The provided document is a general information section from a manual for a Vendo Sanden vending machine, specifically models V21 721, V21 821, and V21 621.
Function Description
This manual outlines the programming, operation, parts, and electrical wiring diagrams for the V21 series vending machines. These machines are equipped with a V21 microprocessor controller that allows for flexible pricing per selection (from $0.00 to $99.99), space-to-sales programming, and energy-saving modes. The primary function of these machines is to dispense various beverages, including 12 oz. cans, 16 oz. glass bottles, and 20 oz. PET bottles, based on customer selection and payment. The vending mechanism is designed to handle different product depths (single, double, triple, and quadruple) and includes a drop sensor assembly to confirm product delivery and cancel credit.

Maintenance Features
- Unpacking and Initial Setup: Instructions are provided for removing shipping materials and leveling the machine. Leveling legs should not raise the vendor more than 1 1/8 inch above the ground.
- Positioning: The vendor must be placed 3 to 4 inches (7.6cm to 10.2cm) away from any rear obstruction to ensure proper air flow for the refrigeration compartment.
- Power Supply Connection:
- CAUTION: Do not use an extension cord.
- Power requirements vary by country and must be verified against the serial plate.
- The power supply must be a properly grounded and polarized outlet. Testing the outlet before plugging in is recommended.
- If power requirements are not met, a licensed electrician should be contacted.
- Refrigeration Area Check: Instructions for checking the condensation pan's position and ensuring the drain tube is correctly attached and free of kinks. A water trap in the condensation pan prevents warm, moist air from reaching the evaporator.
- Vend Mechanism Parts: The manual provides a detailed description of interchangeable vend mechanism parts, including the vend motor assembly, vend bucket, motor coupling cam, gate, gate link, can step, rear bushing, front spacer, and drop sensor assembly. These descriptions aid in understanding and potentially troubleshooting the mechanism.
