Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.

  • Water leak detected during or after installation that cannot be stopped by tightening connections: Shut off water supply immediately. Contain water. Do not restore water until leak is resolved. Escalate if fitting damage is suspected.
  • Structural damage discovered during shelf or cabinet modification: Stop modification. Assess whether the cabinet integrity is compromised. Escalate for structural repair before continuing.
  • If a persistent water leak occurs during connection, immediately shut off the main water supply and call a qualified technician.
  • If structural damage is found during mounting, do not proceed; contact a qualified technician for structural assessment and repair.
