Electric Shock
To avoid potential injury from electric shock, shut off
power to the control box before installing the sensors
or servicing the leak detector system.
Pressure Relief
Your diaphragm pump stays pressurized until
pressure is relieved manually. To help prevent
serious injury from pressurized fluid, such as
splashing in the eyes or on skin, follow the Pressure
Relief Procedure when you stop pumping and before
you install the leak detector sensors. Refer to your
pump manual for the correct Pressure Relief
Procedure.
