Important Notices
Electrical Verify supply voltage, phase, and frequency match nameplate before installation: 440-460-480V, 3.0-Phase, 60 Hz.
Temperature limits Do not exceed max fluid temperature 104°F. Exceeding limits damages seals and motor insulation.
Dry running Do not run dry. ACC 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.
