• If required by application and code, install a safety relief valve to protect
against over temperature and over pressure.
• Do not install with the motor above the impeller. This installation can cause
the pump to run dry leading to premature failure of the pump and voids the
warranty.
4.5 Electrical installation
4.5.1 Precautions
WARNING:
• Make sure that all connections are performed by a qualified
electrician in accordance with all applicable codes,
ordinances and good practices. Failure to follow these
instructions could result in serious injury, death and/or
property damage.
• Before starting work on the unit, make sure that the unit and
the control panel are isolated from the power supply and
cannot be energized.
• Risk of Electrical Shock. To reduce the risk of electric shock,
connect only to a properly grounded, grounding type
receptacle. This warning applies to pumps fitted with flexible
cord connections.
• Electrical Grounding Hazard. Adequate electrical grounding
is required for the safe operation of B&G pumps. The use of
grounded metal conduit assures this requirement. If the
means of connection to the supply-connection box (wiring
compartment) is other than grounded metal conduit, ground
the pump back to the service. Use copper wire at least the
size of the wires supplying power to the pump. Connect the
ground wire to the ground terminal in the wiring
compartment. Failure to follow these instructions could
result in serious personal injury, death and or property
damage.
4.5.2 Connect the wires
1. Loosen the screw that secures the motor cover and remove the screw and
cover.
See
Figure 6: Electrical connections on page 24 for more information.
2. Attach an appropriately sized electrical connector to one of the 7/8”
diameter holes on the side of the conduit box.
