1.Motor Rotation – Upon start-up, the pump "kicks" in the opposite direction of motor rotation.The correct rotation is counter- clockwise (CCW) as viewed from the impeller end of the pump. Rotation direction for 3-phase pumps is changed by reversing two of the power leads.

2.Mechanical Oil Seal – Use a good grade 10 weight non-detergent hydraulic oil (i.e. Shell Turbo 32 or equivalent). Fill oil cavity 75% to 85% full (allow air space for expansion).
