Safety and preparatory steps
Disconnect all power before servicing. Lockout/tagout and verify absence of voltage. Use PPE: insulated gloves, safety glasses, and hearing protection when required. Handle refrigerant circuit and compressor per environmental and safety regulations; only EPA/regionally certified technicians should service refrigerant systems. Use manufacturer-specified replacement parts and approved refrigerants. Improper parts or refrigerant can void warranty and cause system failure. Keep service manual and wiring diagrams accessible. Record serial numbers, firmware versions, and error histories before reconfiguration.
