BEFORE YOU TRUST IT
Field-use checks
- 01Use clean oil and verify the pump can pull down by itself before blaming the system.
- 02Remove valve cores when the procedure and equipment allow, then use large evacuation hoses.
- 03Place the micron gauge away from the pump and isolate the pump for a decay test.
- 04Follow the equipment manufacturer’s evacuation target and standing-vacuum procedure.
04
RED FLAGS
What to avoid
- Selecting only by advertised CFM
- Using a manifold hose set as the default evacuation path
- Treating a low reading at the pump as proof the system is dry and tight
