What is the first procedure to perform when starting up a new unit?

When starting up a new unit, the first procedure to perform should focus on ensuring that the unit is safely powered and that the electrical system is prepared for operation. Checking the voltage is essential because it helps confirm that the power supply is within the required specifications for the unit. This step is crucial as improper voltage levels can lead to equipment damage or malfunction.

Verifying the voltage before turning on the power ensures that the unit will operate correctly and prevents potential electrical issues, which could result in costly repairs or unsafe operating conditions. Understanding the correct voltage requirements and having the appropriate readings before proceeding helps establish a safe working environment and allows for the remaining startup procedures to be conducted effectively.

While checking refrigerant levels, inspecting connections, and turning on the power are also significant steps in the startup process, they should follow after verifying the voltage to ensure that all systems are safe for operation. This structured approach aligns with best practices in the field.
