1.Motor Rotation – Upon start-up, the pump "kicks" in the opposite direction of motor rotation. The correct rotation is counterclockwise (CCW) as viewed from the impeller end of the pump.

2.Mechanical Seal Oil – 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).

3.Control Box - Control box (Table 2) may be required for certain pumping applications.
