Note 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.
Note 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).
Note 3:
Control Box - For unattended operation, CB12, CB12A, CB14, and CB14A Control Boxes (Table 4) are required. All
control boxes provide thermal overload protection.
