BJM Pumps three phase pumps have integral motor overload protection. BJM
recommends that all three phase pumps using a motor starting device also incorporate
motor overload protection. Pumps must be installed in accordance with the National
Electrical Code and all applicable local codes and ordinances. Pumps are not to be
installed in locations classified as hazardous in accordance with National Electrical
Code, ANSI/NFPA 70.
Connect pump to a junction box, outlet box, control box, enclosure with a wiring
compartment that meets NEC and local codes in volume, and applicable fittings for
supply connection. The provision for supply connection shall reduce the risk of water
entry during temporary, limited submersion and shall comply with the applicable
requirements of the Standard for Enclosures for Electrical Equipment, UL 50, or the
standard for Metallic Outlet Boxes, UL 514A, and the standard for Motor-Operated
Water Pumps. UL 778.

Safety glasses must be worn when visually checking impeller
rotation.
Switch ON the pump in inching mode and look into the impeller from the strainer side to
check its normal rotational direction, just before complete stop of the impeller.
Checking before piping connection can be made by looking into the impeller from the
discharge pipe side.
If the rotational direction of the impeller is reverse upon checking, interchange optional
two wires of the power cable.
