When installing a Healy VP-1000 Vac-Motor, which of the following actions is NOT necessary?

The action of replacing the nozzle is not necessary when installing a Healy VP-1000 Vac-Motor because the installation of this particular vapor recovery system is typically independent of the physical nozzle. The motor is designed to operate with the existing setup and is focused primarily on the vapor recovery function rather than the nozzle itself. Proper installation of the Vac-Motor centers around ensuring the motor is securely fitted, connected to appropriate power sources, and integrated into the existing vapor recovery system.

In contrast, wearing eye protection is essential during installation to safeguard against any potential hazards from debris or accidental releases of vapors. Properly barricading the area is also critical to ensure the safety of workers and the public, preventing unauthorized access to a potentially hazardous work zone. Turning off the power to the dispenser is a crucial safety measure that must be taken to avoid electric shock and ensure safe operation when performing any installation or repair work. Each of these actions contributes to maintaining a safe working environment and ensuring the proper functioning of the vapor recovery system, whereas replacing the nozzle does not directly impact the installation process for the Vac-Motor.
