Temperature limits Do not exceed max fluid temperature per nameplate or max ambient temperature 140°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.
