•
Trap air in high points of discharge line can affect the pump
operation.
•
Avoid hydraulic shock by closing the valve near the discharge
before the pump shutdown.
•
The discharge pipe should be as short as possible and fitted
with either a check or gate valve for each pump that uses the
same line. This valve is used to prevent backflow into the
pump which can cause excessive flooding and damage to the
pump. The valve may also be used to stop flow into the pump
to help with priming and starting, shutdown, maintenance,
and pump removal.
Electrical connections.
Power and Cables Control: The cable assembly mounted to the
pump should not be modified in any way except for shortening to a
specific application. Any splice between the pump and the control
panel must be in accordance with all applicable electrical standards.
Do not leave the electrical wire
exposed, as it may reach the motor
and cause serious damage.
The black, white, and red wires are all energy carriers or conductors.
The green wire is the grounding wire.
ATTENTION.
Always use the installed handle, never the cord, to lift the
pump,
