Inspect Threaded Connections for Leaks
This procedure verifies the integrity of the fittings within the water filtration system to prevent leaks and maintain clean water supply.
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.
- Major leak flooding the cabinet: Stop immediately. Isolate water and power. Escalate to facility maintenance.
- If any major leak is observed flooding the cabinet, immediately stop all activity, isolate both the water and power sources, and escalate this issue to a qualified technician.
- For any work involving the water supply or internal plumbing, always consult a qualified technician.
