What must you do if you receive a new fuel dispenser with a motor set for 110 volts but the service station island is serviced for 220 volts?

In this scenario, resetting the motor changeover plate is the appropriate action to take when the fuel dispenser's motor is set for a voltage that does not match the service station's supply voltage. Many motors are designed with adjustable settings that allow them to operate on different voltage levels. By resetting the changeover plate, you can switch the motor's configuration from 110 volts to accommodate the 220 volts supplied by the service station island.

This solution is efficient and cost-effective, as it avoids the need for new equipment or extensive rewiring, both of which could lead to increased costs and downtime. Additionally, it allows for the appropriate function of the fuel dispenser without compromising the overall electrical system's integrity.

Other options involve more significant alterations or equipment changes that may not be necessary if the motor can simply be adjusted to suit the available power supply.
