Important Notices

| Temperature limits | Do not exceed max fluid temperature 194°F or max ambient temperature 131°F. Exceeding limits damages seals and motor insulation. |
| Dry running | Do not run dry. CM pumps use the pumped fluid to lubricate the shaft seal. Dry running destroys the seal within seconds. Install dry-run protection on all automatic installations. |
| Maintenance | Refer to the Grundfos Installation and Operating Manual (IOM) for correct installation, commissioning, and maintenance. Contact PumpStop for documentation. |
