| Electrical | Verify supply voltage, phase, and frequency match nameplate before installation. |
| Temperature limits | Do not exceed max fluid temperature per nameplate. Exceeding limits damages seals and motor insulation. |
| Dry running | Do not run dry. SP 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. |
