Install — kit priorities

Install work leans hard on evacuation quality, nitrogen purge accessories, and tools that stay accurate when you’re opening new systems — not just topping off service calls.

Prioritize

  • Vacuum pump in a sensible CFM class for the systems you install — with micron verification
  • Standalone or manifold-integrated micron gauge (pair with pump page when live)
  • Nitrogen regulator / purge kit class (accessory — follow manufacturer guidance)
  • Flaring, swaging, bending, and torque tools that match the copper work you do
  • Recovery machine available when reclaim is required — sized for install-day logistics

Failure modes to watch

  • Trusting “done enough” without a micron reading you can defend
  • Underpowered pumps on long line sets; oil condition ignored
  • Hose and adapter mismatches that slow jobs and introduce leaks
  • Skipping documented A2L tool / hose requirements on transition equipment
