1. Motor Rotation – Let pump hang freely from a lifting device. Start and stop pump while observing movement
(kick) of pump. If connected correctly the impeller will rotate clockwise (CW) as viewed from above. If pump rotates
counterclockwise interchange any two phases from the power source.
2. Mechanical Seal Oil – Use ISO VG32 lubrication oil, Mobile DTE 24 turbine oil 90 or equivalent. Fill oil chamber 75%
to 85% full (allow air space for expansion).
3. Control Box - For unattended operation, CB12 or CB14 Control Box (Table 3) is required. Control boxes will provide
thermal overload protection.
